Helcophorus murzini sp. n. ( Figs. 42–44 )

Description

Male. Orange. Meso­ and metasternites, abdomen, tarsi, palps and antennomeres 4–11 brownish­black.

Head glabrous, flat behind antennal prominence. Eyes relatively small (interocular distance 3 times as long as the radius). Maxillary palpi slender, with ultimate palpomere parallel­sided, about twice as long as joint 3, flattened at apex. Antennae slender, filiform, extending to slightly beyond the middle of elytra, with antennomere 3 1.3 times longer than antennomere 2 and 2:1.3 times shorter than antennomere 4; antennomeres 4–10 subequal in length; antennomeres 1–3 with reddish decumbent, antennomeres 4–11 with black erect pubescence.

Pronotum transverse, about 1.2 times wider than long, with conspicuous median areola, connected with lateral margins by prominent carinae; lateral margins slightly narrowing anteriorly, with hind angles acute, but relatively short. Scutellum elongate, parallelsided, emarginate at apex.

Elytra very long, more than 4 times longer than wide at humeri, slightly widening posteriorly, with 4 conspicuous primary costae; costa 3 considerably stouter than others; interstices with single row of relatively irregular mostly square cells and traces of double rows basally. Pubescence uniform, short and relatively dense.

Metatrochanters with blunt posterior angles.

Median lobe of aedeagus with straight base in lateral view ( Figs. 42–44 ). Length: 8.0–9.0 mm. Width (humerally): 1.9–2.0 mm. Female. Unknown.

Type material

Holotype male: China, N Yunnan, env. Zhongdian, Shudagang, 3700 m, 22– 24.V.2000, S.Murzin leg.; Paratypes, paratypes, 2 males, same label ( ICM).

Diagnosis

H. murzini sp. n. is placed near H. delicatus Kazantsev , distinguishable by its coloration, the longer elytra with weaker reticulation, and the shape of the aedeagus ( Figs. 42– 44 ).

Etymology

Named after its collector, Dr. S.Murzin (Moscow).
