Description of adults: Examined: 1 . Forewing length: 3.65 mm. Head with erect, hair-like scales; face smoothly scaled, metallic shining; eyes semiglobular, enlarged, about 0.2 mm in diameter, distance of eyes (frontally) about 0.27 mm; maxillary palpi three-segmented, straight, segments 225, 250 and 50 Ám long (from basis to tip), the short terminal segment pointed; labial palpi three-segmented, in total 525 Ám long and thus as long as maxillary palpi; basal segment short, medial and terminal segments of about equal length, straight; medial segment with several distant bristles; antennae in about 5/6 of forewing length; scapus swollen; segments of flagellum with an erect scale each on both sides; haustellum short, broad, only slightly enrolled; underside of thorax metallic shining, legs alike; foretibia without epiphysis; midtibia with a long pair of spurs at distal end; hindtibia with a very long pair of spurs each medially and at distal end; upperside of abdomen with distant scales, underside smoothly scaled.

Distribution:

So far, the species is known only from a single specimen from the type locality, which is Baltic amber from the "Blue Earth" deposit near Kaliningrad.

Biology:

The species is a member of the amber wood biocenosis.

Anatomy:

Venation. In forewing, all R-veins free; R5 preapical; stem of media not recognizeable; A2 + A3 forming a distinct basal loop.

Genitalia. In preparation mostly inside the abdomen and therefore not recognizeable.

Diagnosis:

From other members of the genus Adelites Rebel, 1934, the species is separated primarily by its small size. The forewing length of 3.65 mm is almost only half of that in the other known species.

B>Phylogeny: The short antennae, which do not even reach the forewing length, and the enlarged eyes in males clearly assign the species to the genus Adelites.
