Orphnebius nigrapicalis View in CoL spec. nov.

( Figs 220–222 View Figs 216–235 )

Type material: Holotype ♂: “ Laos, 1.–16.v.1999, Louangphrabang pr., 20°33–4'N 102°14'E, Ban Song Cha (5 km W), 1200 m, Vít Kubáň leg. / Holotypus ♂ Orphnebius nigrapicalis sp. n., det. V. Assing 2015” ( NHMB).

Etymology: The specific epithet is an adjective composed of the Latin adjectives niger (black) and apicalis. It alludes to the infuscate abdominal segment VIII.

Description: Size, coloration, and other external characters as in O. fuscapicalis , except as follows:

antennomeres I–IV blackish-brown; tibiae dark-brown to blackish-brown.

♂: median lobe of aedeagus ( Figs 220–221 View Figs 216–235 ) 0.93 mm long; ventral process short and broad, of subtriangular shape in ventral view; internal sac with large and strongly sclerotized structures; paramere 0.7 mm long, shaped as in Fig. 222 View Figs 216–235 .

♀: unknown.

Comparative notes: Based on the similarly derived morphology of the antennae, the extremely similar remaining external character (including the infuscate abdominal segment VIII), and on the similar morphology of the aedeagus, this species is very closely related to O. fuscapicalis , from which it differs only by the coloration of the antennae and legs, as well as by the shorter, stouter, and in ventral view much broader ventral process of the aedeagus and by the shape of the paramere.

Distribution and natural history: The type locality is situated in Louang Phrabang province, North Laos, at an altitude of 1200 m. The holotype was collected together with O. lunatus , O. extensus , and O. reductus .
