Vojnits, A.: A revision of the "Eupithecia innotata group", I. (Lepidoptera, Geometridae)

Eupithecia praesignata BOHATSCH (PROUT, L. B. : Eupithecia, in : SEITZ, Suppl. ad IV, 1934-39,p. 202). Eupithecia praesignata BOHATSCH, 1893 (VHDALEPP, J. : Ent. Obozr., 1978, 57: 753). Diagnosis. As is to be seen from the description, BOHATSCH assigned (1893) a darker and a ligher form to this taxon; also DIETZE (1913) mentioned this circumstance. The species is represented by the darker specimens; they were the first ones mentioned by BOHATSCH and they also supplied the type. Genitalia, çf : Compared to the species of the "innotata group", the main characteristics are: valva short, ventrum slightly sinuous with alternating convex and concave stretches. Uncus long. Vinculum semicircular. Aedoeagus with even the usually larger chitinous spine also small, the smaller one quite thin. Sternite VIII wide (Fig. 18); $ : Bursa copulatrix piriform, nearly 2/3 padded with chitinous spines. Anterior and posterior apophyses rather short and thin, papillae anales angular. Ductus seminalis originating in midline of bursa, wholly different from the situation observable, for instance, in Eupithecia paupera VOJNITS (Fig 17). Biology. First stages and foodplant unknown. Flight period in July. Distribution. Occurring in Central Asia. — Locus typicus : Transalai. Specific differences. Eupithecia paupera VOJNITS appears to be the nearest relation, so that the two species are not easily distinguishable by external features alone. It is more or less the discal spot which differs in site and shape. The differences in the genitalic configurations are given above. Remarks. PROUT (1915) assumed the distinct specificity of the taxon quite early, though he first treated it as a form of Eupithecia innotata HUFN. DIETZE (1913) thought similarly, mentioning that the systematic position will be decided by anatomical studies. Subsequently, PROUT (1939) considered it unequivocally as a distinct species*.
