New Species in the Eupithecia haworthiata-group* (Studies on Palaearctic Eupithecia Species, Lepidoptera, Geometridae, n.) By A. VOJNITS, Budapest Abstract — The description of six new Eupithecia species (E. pekingiana sp. n., meszarosi sp. n., minibursae sp. n., rudniki sp. n., sidemii sp. n., pseiidoplumbeolata sp. n.) are given from Asia and mainly China. The unknown male of Eupithecia gozmanyi ussuriensis VOJNITS, occurring also in China, is also described. The study of materials originating from Asia, and principally from China, revealed that seemingly hardly different, small, grey or fuscous sjiecimens, hitherto grouped together in the various collections, represent several species new to science. These animals are externally highly similar to Eupithecia haworthiata DBL., frequent in Europe, or to the morphologically also nearly allied E. plumbeolata HAW. Howewer, the structure of the genitaha is so characteristic that the new forms can safely be separated both from one another and from the heretofore described species. The female genitalia differ in excellent and constant features, whereas in the males the differences in primarily the aedoeagi and the shape of tergite VIII are the most conspicuous. The female genitalia are so characteristic that I found it repeatedly justified to describe new species even if I had no conspecific males available for study. In my investigations I had extensively relied on the rich comparative Palaearctic material of the Zoologisches Forschungsinstitut und Museum A. Koenig, Bonn (Curator Dr. U. ROESLER), and of the Zoologische Sammlung des Bayerischen Staates, Munich (Director Dr. W. FORSTER). The study of t3'pes deposited in some other institutions, but chiefly in the Institut für Spezielle Zoologie und Zoologisches Museum der Humboldt Universität, Berlin (Curator Dr. H. HANNEMANN), was also indispensable. It is my agreeable duty to express my thanks for this help also in the present paper. I am also deeply obliged to the Humboldt Foundation, Bad Godesberg, German Federal Republic, for the research stipend making possible my work in various museums in Germany for a whole year.

Eupithecia gozmanyi ussuriensis VOJNITS, ~f new The description of the subspecies was based on six female exemplars (VOJNITS 1972). I have subsequently found 17 other female specimens and 21 male individuals mainly in HONE'S collection from China, The shape, colour and pattern of the male * The author contends that the intergeneric classifications of the various Eupithecia taxa are more or less arbitrary even today, with the "similarity" or "remotely allied" state of the species being adjudged subjectively. The designation "haworthiata-group" serves only for an easier relegation of the species in question within the system of the SEITZ work (and other books), and rests on some external morphological characteristics.
