Pseudoneureclipsis congkem , new species

Figs 61–64

This species is small-sized and with a brown body. The genitalia resemble those of P. boquan , new species, P. erebos Malicky & Sangpradub ( Malicky et al. 2001) , P. quancong , new species, P. u s i a Malicky & Chantaramongkol, particularly by the presence of a lateral flank of each inferior appendage coxopodite. Pseudoneureclipsis congkem is separated from the other species by possessing a single lanceolate finger-like process on each preanal appendage; a pair of sinuous paraproctal processes, not straight; and a broader segment X, forming a longitudinally elongate quadrangular plate with setose triangular ridges and membranous venter, a structure that is more narrow or digitate in the other species.

Male. Forewing length 4.0 mm.

Male genitalia. Segment IX with short tergite and large sternite with rod-like dorsal strap hinged directly to narrow tergite. Segment X forming large elongate quadrangular plate with triangular setose median ridge and membranous venter. Pair of paraproctal processes spine-like, without setae, curving slightly mesoventrad, each with terminal spine-like seta, their basal parts fusing under phallic apparatus forming U-shaped strap beneath phallic apparatus. Preanal appendages slightly elongate papillose flaps; each with lanceolate, rod-like process arising from middle of mesal face. Coxopodites elongate filiform, each with lateral flank and narrowing apex in lateral view; broad at middle laterally and with apex triangular in ventral view. Harpagones located basodorsally, curving slightly ventrad and laterad, each with tapering apex; intersegmental membrane of each inferior appendage (articulation line between coxopodites and harpago) well visible. Phallic apparatus with broad phallobase continuing in dorsad-curving, tube-like phallotheca, slightly constricted at apex; end of phallotheca and protruding endotheca discernible; sclerotized structures invisible; protruded endotheca covered by minute, densely packed microtrichia of 2 distinct sizes.

Holotype male: VIETNAM: Bac Thai Province, Quang Chu, 24–25.v.1987, at light [J. Oláh], (OPC).

Paratypes: Same data as holotype, 18 males.

Etymology. Congkem , from Vietnamese “ quancong kem,” less arm, referring to the fewer arm-like, lanceolate processes on the dorsal complex of the genitalia.
