Electromethes alleni sp. n.

( Figs 1–3 )

Description. Male. Dark brown; elytral margins testaceous.

Eyes bulging, interocular dorsal distance over 3 times greater than eye radius. Maxillary and labial palps slen- der; ultimate maxillary palpomere elongate, ca, 3 times longer than wide, ultimate labial palpomere about 1,5 times longer than wide. Antennae flabellate, attaining to elytral middle, with antennomeres 2 and 3 combined about 2 times shorter than antennomere 4; flabellae of antennomeres 4–10 noticeably longer than antennomeres ( Figs 1–2 ).

Pronotum transverse, ca. 1.5 times as wide as long, convex at disk, with noticeable anterior angles. Scutellum elongate, almost parallel-sided, rounded at apex ( Fig. 1 ).

Elytra long, 3.4 times as long as wide at humeri ( Fig. 1 ).

Tibiae ca. 1.2 times longer than femurs; tarsomere 1 almost as long as tarsomeres 2-4 combined ( Fig. 3 ).

Length (from anterior head margin to end of elytra): 6.4 mm. Width (humerally): 1.7 mm.

Female. Unknown.

Type material: Holotype, 3, specimen No. L- 052011, Baltic amber, Upper Eocene (Insect Centre collection, Moscow).

Diagnosis. Electromethes alleni sp. n., the only known representative of the genus, is easily distinguishable from other omethids by the generic characters.

Etymology. The new species is named after Mr. Albert Allen (Boise, Idaho) who enabled me to study this remarkable Baltic Amber beetle specimen and donated the inclusion to the collection of the Insect Centre, Moscow.
