Pseudoneureclipsis loang , new species

Figs 77–80

This small-sized, brown animal from Vietnam is similar to P. j o s i a Malicky & Chantaramongkol, 1993, from Thailand in having a very short segment IX. The new species differs in several genitalic structures: setose segment X narrows apicad, not forming a broad plate; the preanal appendages have a long, digitiform ventral lobe, not short; the paraproctal processes are slender, spine-like, with broad bases; and the coxopodites are nearly triangular apically in lateral view, not bluntly rounded, and almost parallel-sided in ventral view, not tapering.

Male. Forewing length 4.5 mm.

Male genitalia. Segment IX short, consisting of short tergite and short, sinuous sternite; segment looks like narrow sclerotized strap. Segment X setose, long, triangular, with dorsomesal ridge, entire surface covered with strong setae, strongest setae located mostly on lateral margins and along dorsomesal ridge. Paraproctal processes slender, spine-like, with broad bases, without setae, curving slightly dorsomesad; basal parts meeting under phallic apparatus, forming U-shaped strap beneath phallic apparatus. Preanal appendages each consisting of broad, auriform flap and long, digitiform process arising from ventromesal surface of flap, visible in lateral and dorsal views. Inverior appendages with coxopodites long, parallel-sided, apically triangular. Harpagones located basodorsally on coxopodites, each forming mesoventrad-curving, slender spine. Intersegmental membrane of each inferior appendage (articulation line between coxopodites and harpago) well visible. Phallic apparatus with broad, long phallobase continuing into straight, horizontal, tubelike phallotheca. Dorsal, posteriorly acute spine present at end of broad phallobase. End of phallotheca and protruding endotheca discernible; sclerotized structure scarcely visible inside phallotheca, ending in protruding endotheca; protruded endotheca covered by minute, densely packed microtrichia.

Holotype male: VIETNAM: Bac Thai Province, Quang Chu, 24–25.v.1987, at light [J. Oláh], (OPC). Etymology. Loang , from Vietnamese “loan,” thin, referring to the slender harpagones in the genitalia.
