Eupithecia costisignataDiETZE mitigataT)iETZE (PROUT. L. B. : Eupithecia, in: SEITZ, 1915, IV, p. 294.). Eupithecia costisignata DIETZE (?) mitigata DIETZE (PROUT, L. B.: Eupithecia, in: Seitz, Suppl. ad IV, 1934-39, p. 203). Diagnosis. DIETZE (1908) gave a detailed and very good description of the external morphological features. Genitalia, rf : Valva medium long, dorsum slightly arcuate, basal part of ventrum nearly parallel with dorsum, apical half largely straight to apex; ventrum medially finely projecting. Uncus long, thin. Aedoeagus short, stout, among its chitinous formations most characteristic are a large and arcuate as well as a short and straight dentiform spine. Sternite VIII wide, attenuating, terminally obtusely biapical (Fig. 15); 9 : unknown. Biology. First stages and foodplant unknown. Flight period in May. Distribution. Occurring in Central Asia. — Locus typicus: Lop Nor. Specific differences. The fine pattern on the peculiar beige basic colour already distinguish the species from all near relations, but the male genitalia also offer distinguishing characters. Remarks. DIETZE (1908) had at first described this form as a distinct species. Thus it is the more striking when he enumerated it later (1913) among the forms of Eupithecia costisignata DIETZE. This was first accepted also by PROUT (1915), but later pointed out (1939) that the systematic relegation of the taxon is unsatisfactory; however, this is referable only to the later (DIETZE 1913; PROUT 1915) and not to the earlier (DIETZE 1908) standpoints. DIETZE wrote of four males and one female, preserved in the PÜNGELER and DIETZE collections; he mentions further specimens from DRAUDT'S collection.
