Eleniella kyseluci Berest, 2001 —new junior synonym of Monardia obsoleta Edwards, 1938

Material studied: holotype male, with the data as specified in the original description ( Berest 2001).

Berest (2001) introduced the genus Eleniella for a single new species, Eleniella kyseluci , which she classified in the tribe Strobliellini . The holotype male of E. kyseluci is poorly preserved: most parts of the body, including the antennae, are collapsed ( Fig. 2 ); one of the wings is folded ( Fig. 3 ), and the genitalia are cut into two portions, with the larger one still attached to the abdomen ( Fig. 2 ). On re-examination this specimen proved to belong to Monardia obsoleta Edwards, 1938 , a species of Micromyini with a wide distribution in the Palearctic region ( Jaschhof 1998, Jaschhof & Jaschhof 2009). Berest’s misidentification results obviously from a preparation artifact. The long, basally disappearing CuA1 highlighted in the original description of E. kyseluci ( Berest 2001: fig. 1, referred to in the text as M3+4) is in fact a fold that runs diagonally through one of the wings, which is corrugated, but is missing in the other wing ( Fig. 3 ). Veins M1+2 and CuA2, both of which are often weak and short in M. obsoleta ( Jaschhof 1998) , were depicted approximately correctly. Other diagnostic characters of M. obsoleta distinguishable in the specimen in question are as follows: flagellomere nodes bear distally a small, leaf-shaped translucent sensillum (not described by Berest); there is a dense row of 11–12 postocular bristles (not described); the palpus appears to probably have three segments (not four as described by Berest), the apical one being the longest; the subrectangular claws have two tiny teeth medially; empodia are rudimentary; the arrangement of sensory buds on the wing veins is in accordance with the pattern found in Micromyini (described differently by Berest); tegmen and ejaculatory apodeme show the outline as is typical of Micromyini (not described); and the slender gonostylus is strongly tapered towards the apex and bears a thin, tooth-like spine. Also, the body size, described by Berest (2001) to be about 0.9 mm, fits M. obsoleta better than a Strobliellini , which typically are three to four times larger.
