Pseudoneureclipsis cauky , new species

Figs 57–60

This small-sized brown animal from Vietnam is similar to P. linos Malicky & Bunlue (Malicky et al. 2004) from Thailand. The new species differs in the genitalia, particularly in the presence of setose segment X being bilobed with a wide quadrangular interlobular gap; the preanal appendages each with a very long filiform dorsal process and a shorter, broad-based ventral process, not short, robust and hook-shaped; the paraproctal processes each with a small ventral branch; the coxopodites being slightly excised at the broadened apices, each with a small ventral lobe, not straight-cut; and the coxopodites each having a triangular apex, not rounded. The cephalic and thoracic grooves and setal warts follow the general pattern of the genus.

Male. Forewing length 4.0 mm.

Male genitalia. Segment IX consisting of short tergite and robust sternite, semicircular in lateral view; sternite without long, narrow, dorsal projections; tergite hinged directly to apicodorsal corner of sternite. Segment X setose, with large, quadrangular, basal plate and 2 hand-shaped lobes in dorsal view; interlobular gap wide, quadrangular. Pair of paraproctal processes spine-shaped, without setae, curving slightly mesoventrad, each supplied with small ventral process; basal parts of paraproctal processes meeting under phallic apparatus, forming discernible U-shaped strap beneath phallic apparatus. Preanal appendages bilobed: dorsal lobe long, filiform, with terminal spine; ventral lobe short, with broad base in lateral view. Inferior appendages with coxopodites slightly broadening apicad; each with apex concave and with small apicoventral lobe in lateral view; armed with strong anterad-curving spines at middle of mesal face; in ventral view with triangular apex. Harpagones located basidorsally, each forming strong, straight process in lateral view, curving mesad in ventral view; intersegmental membrane of each inferior appendage (articulation line between coxopodites and harpago) well-visible. Phallic apparatus with broad phallobase continuing in straight, horizontal, tube-like phallotheca; slightly constricted at midway, apically curving ventrad; end of phallotheca and protruding endotheca discernible; sclerotized structures visible inside apex: 1 separate sclerotized rod; 1 pair of long sclerotized rods meeting anteriorly; 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).

Paratype: S ame data as holotype, 1 male.

Etymology. C auky, from Vietnamese “ cauky ,” complex, refering to the complexity of the genitalia.
