Electromethes gen. n.

Type species: Electromethes alleni sp. n.

Description. Adult male. Alate, flattened, elongate (Fig. 1). Head transverse, exposed. Eyes moderately large, spherical. Labrum conspicuous, sclerotised, located anteriad of clypeus. Palps small, slender; ultimate palpomeres securiform. Gula transverse (Fig. 3). Antennal sockets separated by ca. their diameter. Antenna 11-segmented, moderately long, antennomeres 4–10 flabellate; pedicel (antennomere 2) short, subequal in length and width to antennomere 3 and considerably shorter than subsequent antennomeres; pubescence on antennomeres 3–11 short and decumbent (Fig. 2).

Pronotum transverse, narrowed and rounded anteriorly, with punctate convex disk, explanate sides and almost straight posterior angles (Figs 1–2). Prosternum triangular (Fig. 3). Scutellum elongate, rounded at apex (Fig. 1). Discrimen complete, bifurcate near mesoventrite. Elytra elongate, flattened, slightly broadening posteriorly, densely punctate, with inconspicuous longitudinal costae, pubescence short and decumbent (Fig. 1). Epipleuron absent. Metathoracic wings fully developed.

Legs relatively short and robust; hind coxae contiguous; trochanters short; femurs and tibiae straight, tibiae noticeably longer than femurs, almost non-widened distally; tarsomeres 1–4 slightly widened, with plantar pads; claws simple, shortly appendiculate at base.

Abdomen with eight ventrites; exposed portion of ultimate ventrite small, transverse, rounded at apex; ventrites without photic organs. Aedeagus with laterally exposed outside sternite 9 parameres (Fig. 3). Female. Unknown.

Diagnosis. Electromethes gen. n. is easily distinguishable from other omethids by a combination of the following characters: more prominent and more sclerotised labrum, securiform ultimate palpomeres, non-flabellate antennomere 3, location of the bases of flabellae of antennomeres 4–10 at the apices of antennomeres (Fig. 1), triangular prosternum (Fig. 3), absent elytral epipleuron, present plantar pads on tarsomeres 1–2 (Fig. 3), etc.

Etymology. The name of the new genus is derived from "electron", the Greek for "amber", and the genus name " Omethes ". Gender masculine.
