Taphomimus nanensis Kazantsev, 2004, sp. n.

Taphomimus nanensis sp. n. (Figs. 36–38)

Description

Male. Black. Pronotum and elytra orange­red.

Head almost flat behind antennal prominence. Eyes relatively small (interocular distance 2.5 times as long as the radius). Labial palpi slender, with ultimate joint widened apically, longer than palpomeres 1 and 2 combined. Antennae slender, filiform, with antennomere 3 subequal in length and width to antennomere 2 and about 5 times shorter than antennomere 4; 3 antennomeres 1–3 with decumbent pubescence, antennomeres 4–11 with erect pubescence.

FIGURES 36–41. Aedeagi. 36 — Taphomimus nanensis sp. n., ventrally; 37 — laterally; 38 — dorsally; 39 — Dictyoptera gansuensis sp. n., ventrally; 40 — laterally; 41 — dorsally. Scale: 0.5 mm.

Pronotum transverse, 1.25 times wider than long, with conspicuous median areola, connected with sides by prominent carinae; posterior bulges prominent; lateral margins slightly widening anteriorly, with hind angles acute and relatively long. Scutellum elongate, parallel­sided, finely emarginate at apex.

Elytra long, 3 times longer than wide at humeri, only slightly widening posteriorly, with 4 equally developed primary costae; interstices with single row of relatively irregular, mostly transverse, rectangular cells and traces of double rows basally. Short pubescence distributed along costae, with pubescence denser on longitudinal ones.

Metatrochanters with blunt posterior angles.

Aedeagus with long, apically slightly bent median lobe (Figs. 36–38).

Length: 8.5 mm. Width (humerally): 2.4 mm.

Female. Unknown.

Diagnosis

T. nanensis sp. n. differs from all other known species of Taphomimus by the greater size and the shape of its aedeagus (Figs. 36–38). The unique type, and only known specimen, is not intact, and is missing its maxillary palps and portions of its antennae.

Etymology

Named after the type locality.
