THE NORTH AMERICAN SPECIES OF ANASTATUS MOTSCHULSKY (HYMENOPTERA, EUPELMIDAE)

Introduction
The genus Anastatus Motschulsky has never been revised for
North America, though a considerable amount of information has
been published on the biology of some of our species. Anastatus
disparis Ruschka was successfully introduced from Europe into
North America for biological control of the gypsy moth, Porthetria
dispar (L.), in the early years of this century (Clausen, 1956), and there is a very large literature about this species. A. tenuipes Bolivar y Pieltain, a successful parasite of the brown-banded
roach, Supella supellectilium (Serv.), which seems to have followed
its host unaided into the United States, has also accumulated a
rather extensive bibliography (Roth and Willis, 1960). Peck (1963) gives complete bibliographies for all the North
American species of Anastatus up to 1959; later references are in
Burks (1967). Since both these publications are readily avail
able, I have not repeated those citations in this paper. I do give
here, however, the original citation and a brief statement about
hosts and distribution for each species. Where necessary, I have
designated lectotypes from existing cotype series.
In Anastatus antigeny is very great. The males and females
bear little resemblance to each other, figs. 1,2. It is only possible to associate the two sexes through fortunate rearings that happen to produce both sexes under conditions that leave no doubts
about the association of the males and females. Also, the males are rare or absent in some species. As a result, I have had little
reliable male material with which to work and have had to base
the classification entirely on the females.
All the North American species of Anastatus are primary Qgg
parasites that usually develop in the eggs of Hemiptera, Orthop tera, or Lepidoptera. Some of these primary egg parasites may,
however, occasionally act as secondary parasites and develop in

This species has not been reared again since it was described
80 years ago. At present, because of the remaining mutilated
type specimen, it cannot be placed with any certainty among the
other species of the genus. I have not designated this damaged
specimen as the lectotype of the species because, should the
missing cotype specimen be found at some later time, it might be
a more suitable specimen to be chosen as the lectotype.
