( Figs 4–5 View FIGURES 4 – 5 )

Description. Male. Testaceous; elytra dark brown.

Eyes bulging, interocular dorsal distance ca. 3 times greater than eye radius. Maxillary and labial palps slender; ultimate maxillary palpomere elongate, ultimate labial palpomere roundish. Antennae filiform, attaining to elytral two fifths, with antennomere 3 subequal in length to pedicel (antennomere 2) and only slightly shorter than scape ( Fig. 4 View FIGURES 4 – 5 ).

Pronotum strongly transverse, ca. 2.4 times as wide as long, strongly narrowed anteriorly, margined throughout, with prominent acute posterior angles; disk sparsely punctate. Scutellum transverse, triangular, slightly emarginate at apex ( Fig. 4 View FIGURES 4 – 5 ).

Elytra elongate, 2.6 times as long as wide at humeri ( Fig. 1 View FIGURES 1 – 3 ); with ten rows of round impressions in the middle transforming into six rows at apices.

Terminal abdominal ventrite elongate, almost parallel-sided, with rounded apex, ca. 2 times longer than wide and longer than two preceding ventrites together ( Fig. 5 View FIGURES 4 – 5 ).

Length (from anterior head margin to end of elytra): 2.3 mm. Width (humerally): 0.8 mm.

Female. Unknown.

Type material: Holotype, 3, specimen No. L- 042011, Palanga, Lithuania, Baltic amber, Upper Eocene (Insect Centre collection, Moscow).

Diagnosis. Electotreta rasnitsyni sp. n., the only known representative of the genus, is easily distinguishable from other ototretines by the generic characters.

Etymology. The new species is named after a prominent palaeоentomologist Dr. A.P. Rasnitsyn (Moscow).
