Vojnits, A.: New Eupithecia species from Soviet Central Asia (Lepidoptera, Geometridae)
Remarks — The study of a larger series revealed that Eupithecia omnigera VOJNITS and E. recentissima VOJNITS represent the two sexes of the same species, namely that E. recentissima, described on the basis of a single female, is that of E. omnigera diagnosed by a single male specimen. The variability of the species is considerable, both as to external morhology and the configuration of the genitalia. Examined material: 25çfrf and 489 9 from the Pamir, Altai and Vantshu regions, preserved in the Zoological Institute, Academy of Sciences, Leningrad, and the Hungarian Natural History Museum, Budapest.

A. Vojnits. Eupithecia subomnigera sp. n. Derivation of specific name: beside or similar to omnigera. Diagnosis — Alar expanse of fore wings of the single male specimen 22.5 mm, that of two females 22 and 23 mm. Wings elongated. Costa of fore wing slightly, termen hardly, dorsum not, arcuate. Apex obtuse, tornus rounded. Hind wing rounded. Basic colour of fore wing yellowish white, pattern yellow or pale brownish yellow. Discal spot indiscernible. Hind wing densely striated. Underside of wings quite pale, pattern pale, yellowish or fuscous. Cilia with a sericeous shine, pale fuscous, medium long (Plate 1 : figs 1-2). Genitalia — rf: Basically agreeing with those of Eupithecia omnigera VOJNITS (Plate 3 : figs 21-23). — 9 : Rather similar to the elongated bursal type of E. omnigera VOJNITS (Plate 3: fig. 24). Biology — First stages and foodplant unknown. The known exemplars were collected in June-July. Distribution — Ranging in Soviet Central Asia. Locus typicus : Pamir. Specific differences — The genitalia agree considerably with those of Eupithecia omnigera VOJNITS, and differences occur only in certain details. However, the differences in pattern and colour —even with regard to the worn state of the three typespecimens —are so great, and also the shape of the wings of quite another cast, that we are surely dealing with a distinct species. Remarks — The "species pair" Eupithecia omnigera — subomnigera is another good example of the phenomena not rare and causing considerable identification and systematic problems among the Eupithecia species, namely that the genitalia of species standing far from each other as to external morphology may be closely similar and, vice versa, the genitalia of species not even belonging in the same type may agree with each other in external characteristics.
