Elachista deresyensis Traugott-Olsen, 1988: 308 .

Material studied. Turkey: Ürgüp, 19–21. VII.1998, 7 ♂, 1 ♀, 5 km NW Ürgüp, 17. VI.1999, 1 ♂ J. Junnilainen leg. (Coll. J. Junnilainen and MZH).

Diagnosis. E. deresyensis is a medium-sized species of the E. dispunctella compex, with white forewing, scattered with brown tips of scales. The male genitalia are similar to those of E. galactitella , but the uncus lobes of E. deresyensis are broader than in E. galactitella , as long as wide; those of E. galactitella are twice as long as wide. The female genitalia are similar to those of E. elsaella , both having a small colliculum with distinct sclerotized band. The anterior part of the ductus bursae is granulose with longitudinal ribs in E. deresyensis , smooth in E. elsaella .

Biology. Unknown.

Distribution. Turkey.

Remarks. Kaila (1999a) synonymized E. deresyensis with E. galactitella (Eversmann) . Examination of new material suggests that the above synonymy is unjustified, and E. deresyensis is here re-instated as a valid species.

There is a sample of 29 males collected from Turkmenistan: Central part of the Kopetdagh Mts., 15 km W from Firyuza (now Poevryuze), Mt. Dushak, [2100 m a.s.l., mountain xerophytous belt, Juniperus tree savana-like forest], by light trap, VII 1990 V.V. Dubatolov leg. (SZMN, MZH); this taxon closely resembles E. deresyensis ; externally its forewing maculation is black rather than brown, and in the male genitalia the valva is broader and the incision between uncus lobes deeper. Even though the external appearance seems to differ consistantly from E. deresyensis , there is some variation in the width of the valva, similar to E. elsaella . Due to the limited material and unknown female for the Turkmenian taxon, it is not formally named here.
