Pseudoneureclipsis hailan , new species

Figs 69–72

This small-sized, brown animal from Vietnam is similar to P. linos Malicky & Bunlue from Thailand. It is easily distinguished from P. linos by having an extremely long tergite X; a bifid segment X; setose preanal appendages each with a single process; seta-less paraproctal processes with 2 sinuous spines; and harpagones that are longer and more slender.

Male. Forewing length 4.0 mm.

Male genitalia. Segment IX in lateral view with quadrangular sternite and rectangular tergite. Segment X setose, bilobed, with wide triangular dorsal interlobular gap. Pair of paraproctal processes each with 2 spinelike, sinuous processes, without setae; ventral spines curving mesad and meeting under phallic apparatus. Preanal appendages broad-based, each with elongate, single, dorsad-curving process. Inferior appendages with coxopodites short, broad, broadly rounded apically in lateral view; in ventral view long, nearly quadrangular. Harpagones located basodorsally on their coxopodites, each broad and with long setae basally, curving ventrad and mesad to tapering apex. Intersegmental membrane of each inferior appendage (articulation line between coxopodites and harpago) short. Phallic apparatus with broad phallobase continuing into almost straight, horizontal, tube-like phallotheca; end of phallotheca and protruding endotheca discernible; 2 long, thin sclerites visible internally at border of phallotheca and endotheca; protruded endotheca covered by minute, densely packed microtrichia; pair of medium-sized, black spines located ventrally before apex.

Holotype male: VIETNAM: Cuc Phuong, 12.x.1963 [T. Pócsi], ( NHMB). Etymology. Hailan , from Vietnamese “ hai lan,” double, referring to the 2-spined paraproct of the genitalia.
