ANNALES HISTORICO-NATURALES MUSEI NATIONALIS HUNGARICÏ Tomus73. Budapest, 1981 p. 221-237. Data to the Eupithecia fauna of Asia (Lepidoptera, Geometridae)* by A. M. VOJNITS, Budapest Abstract

— Eupithecia comparanda sp. n., E. ingrata sp. n., E. repetita sp. n., E. infecunda sp. n. shown from Pakistan, E.

producta sp. n., E. invicta sp. n. and E. likiangi VOJNITS shown from North India. E. recens DiETZE,an erroneous idenfification from Japan; E. repentinaVomns et DE LAEVER bona species; E. virgaureata invisa BUTLER stat. n. (sec INOUE), erroneous; E. invisa BUTLER = sp. inquierenda. E. bohatschi STAUDINGER = E. tuvinica VIIDALEPP, syn. n. E. viidaleppi sp. n. and E. sacltalini sp. n. from the Far East. E. undata FREYER, an erroneous identification from Mongolia (= E. fennoscandica Knaben). With 20 figures. MR. G. EBERT, Karlsruhe, has kindly sent me for identification a smaller series of Eupithecia specimens collected in Pakistan and North India. The study of the material resulted in the detection of some new species and the demonstration of a rare species from a new locality.

—Studying also INOUE'S excellent works on the Eupithecia species of Japan (1979, 1980), I found some misinterpretations; of these I propose to discuss (or solve) those concerning Eupithecia recens DIETZE and E. invisa BUTLER. One of VIIDALEPP'S works (1976) called my attention to the misidentifications concerning E. bohatschi, a species giving its name to a group recently proved to be very rich in species and of considerable complexity, a fact which may give rise to problems with regard to the interpretation of the entire group. The revision resulted in the synonymization of a species described by VIIDALEPP and the additional description of two new species. In one of my papers on the geometrid moths of Mongolia (VOJNITS 1975), I have shown Eupithecia undata FREYER from that country. This, too, proved to be an erroneous identification, because the specimens in question represent E. fennoscandica KNABEN. I. NEW AND RARE EUPITHECIA SPECIES FROM PAKISTAN AND NORTH INDIA 1. Eupithecia comparanda sp. n.
