— Annls hist.-nat. Mus. natn. hung. 1988 80: 79-90. Abstract — The description of larger series of the new species Eupithecia subomnigera sp. n., E. pamiri sp. n., E. mystica sp. n., E. hysterica sp. n. E. myoma sp. n., E. abundeli sp. n. and E. hangayorum sp. n., found in the Central Asian material of the Zoological Institute, Academy of Sciences, Leningrad. Eupithecia omnigera VOJNITS, 1982 ( = E. recentissima VOJNITS, 1982, syn. n.). With 6 photoplates. Colleagues of the Collection of Lepidoptera and of the Entomological Department, Zoological Institute of the Academy of Sciences, Leningrad, have kindly lent for study a part of the "innotata group" present in their Central Asian material, for which I wish to express my gratitude also in this place. The extraordinary difficulties inherent in interpreting the external morphological characters of the group were again revealed when I found that a large part of the collection, selected as representing members of the group, could by far not be relegated to the innotata assembly, indeed, in more than one case species far removed from that group appeared during dissection. The segregation of taxa actually belonging to the innotata group is rather problematic; the elaboration of also the Central Asian material corroborates the contention that although the genus Eupithecia CURTIS (or the tribe Eupitlieciini) is, largely, of primordial evolvement, a number of its groups are, as also the innotata group, in an intense state of speciation. Eupithecia omnigera VOJNITS Eupithecia omnigera VOJNITS, 1982: Annls hist.-nat. Mus. natn. hung. 74: 218, fig. 1. Eupithecia recentissima VOJNITS, 1982, syn. n.: Annls hist.-nat. Mus. natn. hung. 74: 219, fig. 2. Diagnosis — Alar expanse of fore wings of both males and females highly varying; that of males between 17.5-26 mm (mean 23 mm), that of females between 20-27 mm (mean 24 mm). Pattern rather marked (except in worn specimens). Old specimens turn yellowish or brownish. Genitalia — rf: Of the parts not discussed in detail in the original description, as the pulvinulus, ampulla, falces, clavulus, lamellula, scopulina, and vesica, it is mainly the vesica or rather its sclerotized excrescences which display variability. The valval ventrum also varies somewhat, concerning the size of its projection; the eighth sternite may also be narrower or wider (Plate 3: figs 17-19). — O : The bursa copulatrix is in the majority of cases sphaerical and only in about onethird of the specimens elongated to a shape as shown in the original [figure ( = E. recentissima VOJNITS) (Plate 3: fig. 20). Biology — First stages and foodplant unknown. Imagos in two broods, in April-June and in July. Distribution — Ranging in Soviet Central Asia.
