Vojnits, A.: Data to the Eupithecia fauna of Asia (Lepidoptera, Geometridae)

base, the arms very long (Fig. 19).— 9 : bursa copulatrix elongate, two oppositely situated fields of robust chitinous spines, those in posterior part of bursa of identical size. Only a short section of cervical part of bursa sclerotized. Sternite VIII an upright oblong. Anterior and posterior apophyses very long. Papillae anales elongate, heavily sclerotized (Fig. 17). Biology — First stages and foodplant unknown. Both known specimens have been collected in July. Distribution — Known from the Far East. Locus typicus: Tomovsk, Sachalin. Specific differences — The new species stands nearest to E. bohatschi STAUDINGER, 1987, differring externally mainly by the more detailed and vivid pattern. The male genitalia are more heavily sclerotized, the valvae wider, the arms of sternite VIII larger. In the female genitalia, the location of the patches of chitinous spines and the shape of the bursa copulatrix are different, and the apophyses are also longer. Holotype çf : "Sahhalin Tomovsk, 12-14. 7. 1975, leg. J. Viidalepp" "Eupithecia bohatschi Stgr. det. Viidalepp 1977" "Gen prep. No. 11 222 çf Dr. A. Vojnits, Budapest TTM". — Paratype: Chabarowsk, airport, 13. 7. 1970, 1 9. Slides : Nos. 11.222 (çf), 11.085 (9), gen. prep. Á. Mészár and A. Vojnits. Remarks — As already stated above, all specimens identified as E. bohatschi by VIIDALEPP, and later sent to me for study, proved to represent a new species (= viidaleppi sp. n.), with one exception. This latter specimen became the holotype of Eupithecia sachalini sp. n. Irrespectively of specific assignment, I should like to emphasize that the male specimens of the alleged series of bohatschi could be segregated, both as to external morphological features and especially the configuration of the genitalia, into two sharply different forms. V. EUPITHECIA FENNOSCANDICA KNABEN FROM MONGOLIA Eupithecia fennoscandica KNABEN, 1949, Ent. Tidskrift, 70 (1-2) : 77.81, Figs. A-E, A-H, Pl. 1. Eupithecia undata FREYER, 1858, N. Beitr. z. Schmetterlingskunde, 4: 54. In the second part of my papers discussing the Eupithecia species of Mongolia (VOJNITS 1975), I treated E. undata FREYER under serial number 21. VIIDALEPP suggested (1977) that this must be a case of misidentification. On the basis of VIIDALEPP'S work I have again examined the specimen and can now state that my earlier standpoint was wholly erroneous ("the genital slide assigns it unequivocally to this species"). The animal in question represents E. fennoscandica KNABEN, the species shown also by VUDALEPP from Mongolia. The species E. undata FREYER is to be deleted from the Mongolian Eupithecia fauna, and to be substituted by E. fennoscandica KNABEN with the following (unchanged) data (male genitalia represented by Fig. 20): Examined material — Archangaj aimak : Changaj Gebirge, zwischen Somon Ichtamir and Somon Culuut, 20 km W von Ichtamir, 2150 m, 19.

I am also indebted to DR. U. ROESLER (Bonn, and later Karlsruhe), DR. H. BACK (Bonn), PROF. DR. F. SAUER (Bonn), G. EBERT (Karlsruhe), DR. W. FORSTER (Munich), DR. H. J. HANNEMANN (Berlin), J. VIIDALEPP (Tartu), PROF. H. INOUE (Bushi), for their extensive help partly in the course of my work in the various institutions and partly for the loan of type-materials; their support had largely contributed to the successful execution of my work.
