Helcophorus gobindanus sp. n. ( Figs. 45–47 )

Description

Male. Orange. Antennomeres 4 to 11 dark brown; abdominal ventrites dark brown, gradually becoming reddish brown apically.

Head flat behind antennal prominence. Eyes small (interocular distance 3 times as long as the radius). Labial palps slender, with ultimate palpomere widened and flattened apically, about the length of palpomeres 2 and 3 combined. Antennae filiform, extending to slightly beyond the middle of elytra; antennomere 3 equal in length, but wider than antennomere 2 and both combined about as long as antennomere 4; antennomeres 4–10 subequal in length; antennomeres 1–3 with reddish decumbent pubescence, following antennomeres with short erect pubescence.

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

Elytra long, 3.6 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 mostly transverse rectangular cells and feeble traces of double rows basally. Pubescence uniform, short and decumbent.

Metatrochanters with acute posterior angles.

Aedeagus narrow, with inconspicuous apical notch of parameres dorsally ( Figs. 45– 47 ).

Length: 10.2 mm. Width (humerally): 2.5 mm. Female. Unknown.

Diagnosis

H. gobindanus sp. n. is similar and obviously closely related to H. miniatus , from which it differs by the darker antennae and the shape of the aedeagus ( Figs. 45–47 ).

Etymology

Named after the type locality.
