Platia, Giuseppe & Ahmed, Zubair, 2016, Contribution to the fauna of click beetles (Coleoptera: Elateridae) from Pakistan., Arquivos Entomolóxicos 16, pp. 3-28 : 17-18

Phorocardius tibialis n. sp. ( Figs. 1 9 , 19a , 26, 26a , 28, 39, 65)

Material examined. Holotype ♂ - Pakistan: Chakri , Islamabad , 29.VI.2013 ( ZACP); 1 Paratype ♀ - Trai, Lower Dir, 3.VIII.2014 ( CPG).

Diagnosis. Very similar to P. pakistanicus n. sp., it is immediately separated by the tibiae dilated and with very strong, thickened pubescence.

Description.

Male. Moderately shiny; entirely ferruginous with blackish shadings on the base of elytra around the scutellum; covered with dense, long an thickened, particularly on the tibiae, yellowish pubescence.

Frons slightly impressed between the eyes and before the anterior margin, this subarcuate, directed downwards and protruding above the clypeus; punctuation coarse with punctures variable in size, simple or vaguely umbilicate with very short shiny intervals or contiguous.

An tennae mu tila ted.

Pronotum 1,15x longer than wide, widest at the middle, convex; sides moderately arcuate from the middle regularly converging to the posterior angles, the latter short, truncate, not divergent, with a very fine, few visible carina; lateral suture -like margins substraight, very fine, obsolete before the anterior margin; punctuation much more fine than frontal punctuation, uniformly distributed, punctures approximately of the same size, deep, simple with intervals, shiny, on average equal to their diameters.

Scutellum heart-shaped, as long as wide, impressed at middle very finely punctured.

Elytra 2,5x longer than pronotum and a little wider than it, convex, rather acuminated at apices; sides from base regularly converging to the apices; striae well marked and punctured, interstriae convex from base to near the apices with the eighth interstria subcostiform and the extreme compressed.

Anterior and median tibiae dilated in the middle with very strong, thickened pubescence on the outer margin as in the fig. 28.

Claws bifid before the apex.

Male genitalia as in the Figs. 19, 19a (length 1.31 mm).

Female. Identical to the male. We can evaluate the length of antennae because they are also mu tila ted.

Bursa copulatrix sclerified as in the Figs. 26, 26a .

Size. Length 8.5 (♂) - 1 0.0 mm (♀); width 2.09 (♂) - 2.50 mm (♀).

Etymology. The name is derived from the dilated tibiae.
