Pseudoneureclipsis dongian , new species

Figs 65–68

This species from North Vietnam resembles P. h a i Malicky, 1995, from South Vietnam (Nam Ct Tien). It is separated from P. h a i by its clearly triangular inferior appendages, not long and oval; the setiferous segment X being deeply excised medially in dorsal view, with 2 lateral, triangular lobes; and the phallic apparatus with a single, long spine, not 2 broad spines as in P. hai .

Male. Forewing length 4.0 mm.

Male genitalia. Segment IX with about equally large tergite and sternite, both with narrowing lateral rods articulating in lateral hinge joints. Segment X setose, sub-triangular in lateral view, deeply excised mesally and produced into 2 triangular lobes in dorsal view; interlobular gap triangular. Pair of paraproctal processes spine-like, bare, without setae, curving slightly dorsad apically, their bases located ventrally and laterally of phallic apparatus, articulating with bases of preanal appendages. Preanal appendages broad, nearly triangular in lateral view; narrowly triangular in dorsal views. Coxopodites broadening distad, nearly triangular in lateral view; narrowing, sharply triangular, with laterad-curving apices in ventral view. Harpagones positioned basidorsally, basal part robust; distal part setose and forming long, slender hook curving posterad, then ventromesad. Intersegmental membrane of each inferior appendage (articulation line between coxopodites and harpago) well visible. Phallic apparatus with broad phallobase continuing into straight, horizontal, tubelike phallotheca; end of phallotheca and protruding endotheca discernible; long, slender, single spine associated with phallic apparatus.

Holotype male: VIETNAM: Tamdao, 200 m, 12.x.1986, at light [J. Oláh], (OPC). Etymology. Dongian , from Vietnamese “don gian,” single, referring to the single specimen collected of this species.
