Introduction

The genus Jujubinus Monterosato 1884 comprises a small group of marine trochids (Gastropoda Trochidae)

living mostly in the intertidal zone down to about 80 m and consistently associated with algal vegetation andor

marine angiosperms (Mariottini et al 2013) The alpha-taxonomy and distribution of this genus remains

unresolved The genus was described by Monterosato (1884a) only briefly ldquoJujubinus Monts (nov sect)

Conchiglie piccole ornamentate che formano un gruppo ben distinto dal Zizyphinusrdquo (small shells ornamented

forming a distinct group of Zizyphinus) In a further work by Monterosato (1884b) the description of this genus

was slightly improved Many papers dealing with this genus have been published in the last forty years Nordsieck

(1973) commenting the European distribution of Jujubinus species described several subgenera some of them not

ranked as valid taxa by Ghisotti amp Melone (1975) in their revision of this genus Some of the Mediterranean

Jujubinus species were discussed by Curini-Galletti amp Palazzi (1980) Curini-Galletti (1982andashc) Cretella

(1992ndash1993) Bogi amp Campani (2005) and Spanu (2011) while eastern Atlantic taxa were treated by Gofas (1991)

Rolaacuten amp Templado (2001) Rolaacuten amp Swinnen (2009) and Avila et al (2011) including the description of some new

species

According to WoRMS (2013) the genus Jujubinus is represented by 29 species 18 are listed by CLEMAM

(Gofas amp Le Renard 2013) as European species most of them restricted to the Mediterranean Sea The typical

Jujubinus shell has a slender trochiform shape with a sculpture consisting of 4ndash8 spiral threads of variable strength

often beaded and with tiny prosocline lamellae between the spiral threads (Monterosato 1884a) The

Mediterranean species Jujubinus curinii Bogi amp Campani 2005 shows a peculiar sculpture consisting of flat spiral

threads which are pairing in the abapical part of the last whorl lacking lamellae between the spiral threads and

with a smaller sutural cord (Bogi amp Campani 2005) This species is endemic to the Strait of Messina and to our

knowledge its distribution is limited to the coralligenous bottoms offshore the coast of Scilla (Calabria Italy) The

Messina Strait is considered as a separate Mediterranean biogeographical microsector (Bianchi 2004) inhabited by

rich benthic invertebrate communities and some particular assemblages that are unknown from other

Mediterranean regions (Giacobbe et al 2007 Bo et al 2009 Salvati et al 2010) Recently we had the opportunity

to examine shells of Jujubinus from two locations in the Sicily Channel (Skerki and Talbot Banks) The studied

Discussion

Jujubinus curinii (Figs 113ndash118) differs from all other Atlantic and Mediterranean Jujubinus species by showing

a teleoconch sculpture with flat spiral cords each consisting of two paired cordlets and by lacking the typical

prosocline lamellae present in the spiral furrows between cords occurring in all other Jujubinus species so far

Zootaxa 3815 (4) copy 2014 Magnolia Press middot 587NEW JUJUBINUS SPECIES FROM SICILY

described SEM analysis has confirmed the lack of prosocline lamellae in J curinii and revealed that the flat spiral

cords described in the original description are formed by up to eight spiral lines and not all the cords are

subdivided in two cordlets (Figs 29ndash212 311ndash315) Furthermore at high magnification the whole teleoconch

appears to be densely microsculptured by fine prosocline growth striae including the basal cord The two new taxa

described in this work belong to the J curinii complex and they share the same diagnostic features related to the

presence of flat spiral cords and lack of prosocline lamellae

Both J eleonorae n sp and J trilloi n sp though similar to J curinii are clearly distinct taxa Jujubinus

eleonorae n sp (Figs 11ndash16 21ndash24 31ndash35) differs from J curinii (Figs 113ndash118 29ndash212 311ndash315) by

having (a) stouter shell (b) distinct ratchet spiral ornament ie spiral are asymmetric steeply sloping adapically

and shallowly sloping abapically (absent in J curinii) (c) basal cord bigger and more distinct (d) different shell

colour Jujubinus trilloi n sp (Figs 17ndash112 25ndash28 36ndash310) differs from J curinii by having (a) larger shell

(b) teleoconch shape less turriculated (c) larger base (d) basal cord wider and more pronounced (e) fewer but

larger spiral cords (f) different shell colour with distinct axial opisthocline brown-reddish narrow bands Jujubinus

eleonorae n sp differs from J trilloi n sp by having (a) stouter shell (b) spiral cords distinctly stepped (c) basal

cord stronger and more marked (d) different shell colour with yellowish-orange bands

To summarize J trilloi is closer to J curinii than J eleonorae because they share a similar shell outline

sculpture and background colour Interestingly the distribution of both new taxa seems to be limited to the Sicily

Channel in particular to two peculiar marine spots J eleonorae n sp from the Skerki Bank and J trilloi n sp

from the Talbot Bank Apparently there is no geographical overlapping between these two new taxa For this

reason and due to differences in shell morphology we consider them as distinct endemic species (Fig 4)

Unfortunately these new records lack any information regarding the accompanying benthic community We

conservatively consider the new species as infralittoral without speculating upon their precise positions within this

zone (upper or lower) The two new species differ from J ruscurianus (Weinkauff 1868) which is distributed in

the western Mediterranean Sea (Spain Africa) and in the eastern Atlantic (Portugal Canary Islands) (Locard

1903 Gofas et al 2011) This species differs in several shell characters mainly in teleoconch sculpture and it

clearly belongs to the Jujubinus group with fine prosocline lamellae between spiral lamellae a diagnostic feature

re-described by Cretella (1992ndash1993 vol 266 p 49) We also had the opportunity to examine J ruscurianus type

material stored at the Museo Civico di Zoologia di Roma (Rome Italy) confirming the differences between J

ruscurianus and the two new species described herein

SMRIGLIO ET AL588 middot Zootaxa 3815 (4) copy 2014 Magnolia Press

Jujubinus catenatus Ardovini 2006 described from the Sicily Channel differs from the new taxa described

herein by the shell shape (more elongated in J catenatus) and its sculpture showing the typical prosocline lamellae

between the spiral cords (absent in the J curinii species complex) Furthermore J catenatus is a a circalittoral

species being collected at a depth of 45ndash70 m but no coordinates of the locus typicus were reported (Ardovini

2006) Similar to the Strait of Messina from where the endemic J curinii has been described (Bogi amp Campani

2005) the Sicily Channel represents a Mediterranean location of high diversity for the genus Jujubinus The

occurrence of three endemic Jujubinus species in such a restricted geographical area could be explained by specific

preferences to particular habitats exclusive to this area possibly combined to limited larval dispersal capabilities

Jujubinus from the Sicily Channel is not an isolated case of gastropod endemism in the Mediterranean Sea For

example the trochid Gibbula nivosa Adams 1851 is endemic near Malta Island (Evans et al 2011) and probably

has restricted larval dispersal

Discussion

Jujubinus curinii (Figs 113ndash118) differs from all other Atlantic and Mediterranean Jujubinus species by showing

a teleoconch sculpture with flat spiral cords each consisting of two paired cordlets and by lacking the typical

prosocline lamellae present in the spiral furrows between cords occurring in all other Jujubinus species so far

Zootaxa 3815 (4) copy 2014 Magnolia Press middot 587NEW JUJUBINUS SPECIES FROM SICILY

described SEM analysis has confirmed the lack of prosocline lamellae in J curinii and revealed that the flat spiral

cords described in the original description are formed by up to eight spiral lines and not all the cords are

subdivided in two cordlets (Figs 29ndash212 311ndash315) Furthermore at high magnification the whole teleoconch

appears to be densely microsculptured by fine prosocline growth striae including the basal cord The two new taxa

described in this work belong to the J curinii complex and they share the same diagnostic features related to the

presence of flat spiral cords and lack of prosocline lamellae

Both J eleonorae n sp and J trilloi n sp though similar to J curinii are clearly distinct taxa Jujubinus

eleonorae n sp (Figs 11ndash16 21ndash24 31ndash35) differs from J curinii (Figs 113ndash118 29ndash212 311ndash315) by

having (a) stouter shell (b) distinct ratchet spiral ornament ie spiral are asymmetric steeply sloping adapically

and shallowly sloping abapically (absent in J curinii) (c) basal cord bigger and more distinct (d) different shell

colour Jujubinus trilloi n sp (Figs 17ndash112 25ndash28 36ndash310) differs from J curinii by having (a) larger shell

(b) teleoconch shape less turriculated (c) larger base (d) basal cord wider and more pronounced (e) fewer but

larger spiral cords (f) different shell colour with distinct axial opisthocline brown-reddish narrow bands Jujubinus

eleonorae n sp differs from J trilloi n sp by having (a) stouter shell (b) spiral cords distinctly stepped (c) basal

cord stronger and more marked (d) different shell colour with yellowish-orange bands

To summarize J trilloi is closer to J curinii than J eleonorae because they share a similar shell outline

sculpture and background colour Interestingly the distribution of both new taxa seems to be limited to the Sicily

Channel in particular to two peculiar marine spots J eleonorae n sp from the Skerki Bank and J trilloi n sp

from the Talbot Bank Apparently there is no geographical overlapping between these two new taxa For this

reason and due to differences in shell morphology we consider them as distinct endemic species (Fig 4)

Unfortunately these new records lack any information regarding the accompanying benthic community We

conservatively consider the new species as infralittoral without speculating upon their precise positions within this

zone (upper or lower) The two new species differ from J ruscurianus (Weinkauff 1868) which is distributed in

the western Mediterranean Sea (Spain Africa) and in the eastern Atlantic (Portugal Canary Islands) (Locard

1903 Gofas et al 2011) This species differs in several shell characters mainly in teleoconch sculpture and it

clearly belongs to the Jujubinus group with fine prosocline lamellae between spiral lamellae a diagnostic feature

re-described by Cretella (1992ndash1993 vol 266 p 49) We also had the opportunity to examine J ruscurianus type

material stored at the Museo Civico di Zoologia di Roma (Rome Italy) confirming the differences between J

ruscurianus and the two new species described herein

Bank) and J curinii (circle Scilla)

SMRIGLIO ET AL588 middot Zootaxa 3815 (4) copy 2014 Magnolia Press

Jujubinus catenatus Ardovini 2006 described from the Sicily Channel differs from the new taxa described

herein by the shell shape (more elongated in J catenatus) and its sculpture showing the typical prosocline lamellae

between the spiral cords (absent in the J curinii species complex) Furthermore J catenatus is a a circalittoral

species being collected at a depth of 45ndash70 m but no coordinates of the locus typicus were reported (Ardovini

2006) Similar to the Strait of Messina from where the endemic J curinii has been described (Bogi amp Campani

2005) the Sicily Channel represents a Mediterranean location of high diversity for the genus Jujubinus The

occurrence of three endemic Jujubinus species in such a restricted geographical area could be explained by specific

preferences to particular habitats exclusive to this area possibly combined to limited larval dispersal capabilities

Jujubinus from the Sicily Channel is not an isolated case of gastropod endemism in the Mediterranean Sea For

example the trochid Gibbula nivosa Adams 1851 is endemic near Malta Island (Evans et al 2011) and probably

has restricted larval dispersal

Discussion

Jujubinus curinii (Figs 113ndash118) differs from all other Atlantic and Mediterranean Jujubinus species by showing

a teleoconch sculpture with flat spiral cords each consisting of two paired cordlets and by lacking the typical

prosocline lamellae present in the spiral furrows between cords occurring in all other Jujubinus species so far

Zootaxa 3815 (4) copy 2014 Magnolia Press middot 587NEW JUJUBINUS SPECIES FROM SICILY

described SEM analysis has confirmed the lack of prosocline lamellae in J curinii and revealed that the flat spiral

cords described in the original description are formed by up to eight spiral lines and not all the cords are

subdivided in two cordlets (Figs 29ndash212 311ndash315) Furthermore at high magnification the whole teleoconch

appears to be densely microsculptured by fine prosocline growth striae including the basal cord The two new taxa

described in this work belong to the J curinii complex and they share the same diagnostic features related to the

presence of flat spiral cords and lack of prosocline lamellae

Both J eleonorae n sp and J trilloi n sp though similar to J curinii are clearly distinct taxa Jujubinus

eleonorae n sp (Figs 11ndash16 21ndash24 31ndash35) differs from J curinii (Figs 113ndash118 29ndash212 311ndash315) by

having (a) stouter shell (b) distinct ratchet spiral ornament ie spiral are asymmetric steeply sloping adapically

and shallowly sloping abapically (absent in J curinii) (c) basal cord bigger and more distinct (d) different shell

colour Jujubinus trilloi n sp (Figs 17ndash112 25ndash28 36ndash310) differs from J curinii by having (a) larger shell

(b) teleoconch shape less turriculated (c) larger base (d) basal cord wider and more pronounced (e) fewer but

larger spiral cords (f) different shell colour with distinct axial opisthocline brown-reddish narrow bands Jujubinus

eleonorae n sp differs from J trilloi n sp by having (a) stouter shell (b) spiral cords distinctly stepped (c) basal

cord stronger and more marked (d) different shell colour with yellowish-orange bands

To summarize J trilloi is closer to J curinii than J eleonorae because they share a similar shell outline

sculpture and background colour Interestingly the distribution of both new taxa seems to be limited to the Sicily

Channel in particular to two peculiar marine spots J eleonorae n sp from the Skerki Bank and J trilloi n sp

from the Talbot Bank Apparently there is no geographical overlapping between these two new taxa For this

reason and due to differences in shell morphology we consider them as distinct endemic species (Fig 4)

Unfortunately these new records lack any information regarding the accompanying benthic community We

conservatively consider the new species as infralittoral without speculating upon their precise positions within this

zone (upper or lower) The two new species differ from J ruscurianus (Weinkauff 1868) which is distributed in

the western Mediterranean Sea (Spain Africa) and in the eastern Atlantic (Portugal Canary Islands) (Locard

1903 Gofas et al 2011) This species differs in several shell characters mainly in teleoconch sculpture and it

clearly belongs to the Jujubinus group with fine prosocline lamellae between spiral lamellae a diagnostic feature

re-described by Cretella (1992ndash1993 vol 266 p 49) We also had the opportunity to examine J ruscurianus type

material stored at the Museo Civico di Zoologia di Roma (Rome Italy) confirming the differences between J

ruscurianus and the two new species described herein

Bank) and J curinii (circle Scilla)

SMRIGLIO ET AL588 middot Zootaxa 3815 (4) copy 2014 Magnolia Press

Jujubinus catenatus Ardovini 2006 described from the Sicily Channel differs from the new taxa described

herein by the shell shape (more elongated in J catenatus) and its sculpture showing the typical prosocline lamellae

between the spiral cords (absent in the J curinii species complex) Furthermore J catenatus is a a circalittoral

species being collected at a depth of 45ndash70 m but no coordinates of the locus typicus were reported (Ardovini

2006) Similar to the Strait of Messina from where the endemic J curinii has been described (Bogi amp Campani

2005) the Sicily Channel represents a Mediterranean location of high diversity for the genus Jujubinus The

occurrence of three endemic Jujubinus species in such a restricted geographical area could be explained by specific

preferences to particular habitats exclusive to this area possibly combined to limited larval dispersal capabilities

Jujubinus from the Sicily Channel is not an isolated case of gastropod endemism in the Mediterranean Sea For

example the trochid Gibbula nivosa Adams 1851 is endemic near Malta Island (Evans et al 2011) and probably

has restricted larval dispersal

Page 6: \u003cp class=\"HeadingRunIn\"\u003e\u003cstrong\u003eDescription of two new \u003cem\u003eJujubinus\u003c/em\u003e species (Gastropoda: Trochidae) from the Sicily Channel, with notes

described SEM analysis has confirmed the lack of prosocline lamellae in J curinii and revealed that the flat spiral

cords described in the original description are formed by up to eight spiral lines and not all the cords are

subdivided in two cordlets (Figs 29ndash212 311ndash315) Furthermore at high magnification the whole teleoconch

appears to be densely microsculptured by fine prosocline growth striae including the basal cord The two new taxa

described in this work belong to the J curinii complex and they share the same diagnostic features related to the

presence of flat spiral cords and lack of prosocline lamellae

Both J eleonorae n sp and J trilloi n sp though similar to J curinii are clearly distinct taxa Jujubinus

eleonorae n sp (Figs 11ndash16 21ndash24 31ndash35) differs from J curinii (Figs 113ndash118 29ndash212 311ndash315) by

having (a) stouter shell (b) distinct ratchet spiral ornament ie spiral are asymmetric steeply sloping adapically

and shallowly sloping abapically (absent in J curinii) (c) basal cord bigger and more distinct (d) different shell

colour Jujubinus trilloi n sp (Figs 17ndash112 25ndash28 36ndash310) differs from J curinii by having (a) larger shell

(b) teleoconch shape less turriculated (c) larger base (d) basal cord wider and more pronounced (e) fewer but

larger spiral cords (f) different shell colour with distinct axial opisthocline brown-reddish narrow bands Jujubinus

eleonorae n sp differs from J trilloi n sp by having (a) stouter shell (b) spiral cords distinctly stepped (c) basal

cord stronger and more marked (d) different shell colour with yellowish-orange bands

To summarize J trilloi is closer to J curinii than J eleonorae because they share a similar shell outline

sculpture and background colour Interestingly the distribution of both new taxa seems to be limited to the Sicily

Channel in particular to two peculiar marine spots J eleonorae n sp from the Skerki Bank and J trilloi n sp

from the Talbot Bank Apparently there is no geographical overlapping between these two new taxa For this

reason and due to differences in shell morphology we consider them as distinct endemic species (Fig 4)

Unfortunately these new records lack any information regarding the accompanying benthic community We

conservatively consider the new species as infralittoral without speculating upon their precise positions within this

zone (upper or lower) The two new species differ from J ruscurianus (Weinkauff 1868) which is distributed in

the western Mediterranean Sea (Spain Africa) and in the eastern Atlantic (Portugal Canary Islands) (Locard

1903 Gofas et al 2011) This species differs in several shell characters mainly in teleoconch sculpture and it

clearly belongs to the Jujubinus group with fine prosocline lamellae between spiral lamellae a diagnostic feature

re-described by Cretella (1992ndash1993 vol 266 p 49) We also had the opportunity to examine J ruscurianus type

material stored at the Museo Civico di Zoologia di Roma (Rome Italy) confirming the differences between J

ruscurianus and the two new species described herein

Bank) and J curinii (circle Scilla)

SMRIGLIO ET AL588 middot Zootaxa 3815 (4) copy 2014 Magnolia Press

Jujubinus catenatus Ardovini 2006 described from the Sicily Channel differs from the new taxa described

herein by the shell shape (more elongated in J catenatus) and its sculpture showing the typical prosocline lamellae

between the spiral cords (absent in the J curinii species complex) Furthermore J catenatus is a a circalittoral

species being collected at a depth of 45ndash70 m but no coordinates of the locus typicus were reported (Ardovini

2006) Similar to the Strait of Messina from where the endemic J curinii has been described (Bogi amp Campani

2005) the Sicily Channel represents a Mediterranean location of high diversity for the genus Jujubinus The

occurrence of three endemic Jujubinus species in such a restricted geographical area could be explained by specific

preferences to particular habitats exclusive to this area possibly combined to limited larval dispersal capabilities

Jujubinus from the Sicily Channel is not an isolated case of gastropod endemism in the Mediterranean Sea For

example the trochid Gibbula nivosa Adams 1851 is endemic near Malta Island (Evans et al 2011) and probably

has restricted larval dispersal
