Pahamunaya khoii , new species

Figures 109–115

Diagnosis: This new species is most similar to P. directoris from which it is separated by the shape of the gonopods, and the complex structure of the fused cerci and paraprocts. In addition the setose segment X narrows towards its apex and is simple, while in P. directoris segment X is bilobed.

Description: Male. Body pale brown with lighter setal warts covered with darker setae. Maxillary palp formula II-I-IV-III-V. Anterior tentorial pits located laterally ( Fig. 109 ), short pregenal area, frontoclypeal area broad; pair of frontal lateral compact setose warts and nearly equally large clypeal lateral compact setose warts present; clypeal warts circular; frontal lateral warts inverted drop-shaped. Coronal groove well pigmented, situated on posterial 2/3rds of vertex ( Fig. 110 ). Pair of crescent-shaped, anterad-turning occipital compact setose warts dominating on dorsum together with pair of rounded vertexal ocellar compact setose warts and pair of vertexal lateral preocellar setose warts. Vertexal lateroantennal and fused vertexal medioantennal warts fused. Narrow postgenal setose warts present along posterior ocular groove. Anterior tentorial arms thin ( Fig. 111 ); posterior tentorial arms short, broad; tentorial bridge well-developed, supplied with small, broad anteromesal protuberance. Forewing length 3.0 mm.

Male genitalia. Sternite IX triangular ( Fig. 112 ), with long digitate process on each posterior margin midway between dorsal articulation of gonopod and posterodorsal corner. Tergum IX membranous. Segment X well developed, semimembranous, monolobed, ligulate, as long as dorsal paraproctal processes and cerci; dorsoapical 1/3 rd densely setose ( Fig. 113 ). Cerci elongate, rod-like, heavily sclerotized, glabrous along basal 2/3rds, setose and bending slightly mesad in distal 1/3rd; each with apex pointed; base fused to paraproctal complex. Paraproctal complexes each with obliquely elongate, rounded, basal plate ( Fig. 113 ); long, slender, spine-like dorsal paraproctal process; and short, stout, ventral paraproctal process, with opposing ventral paraproctal processes tapering and curving mesad, almost touching mesally, forming subphallic bridge, embrancing phallic apparatus ventrally. Gonopods trilobed ( Fig. 112 ) with dorsolateral, 2-lobed branch and ventromesal lobe with longitudinal ridge visible in lateral and ventral views ( Figs. 112, 114 ). Phallic apparatus ( Fig. 115 ) complex; base thick, dome-shaped in lateral view; more distally tubular, arching, produced ventrally into stout, median, heavily sclerotized, ventrad-curving process; 2 small lateral wings present ventrally; single triangular hump present dorsoapically; small weakly sclerotized, finger-like protrusion present at apex of membranous endophallus; pair of triangular sclerites possibly representing phallotremal sclerites visible on retracted membranes at midlength of phallotheca.

Holotype male: VIETNAM: Lamdong : Baoloc, Duchma stream, 26.x.1988, sweep net [J. Oláh]— ( OPC) . Paratypes: Same data as holotype— 1 male ( OPC) ; Baco stream, 26.x.1988, sweep net [J. Oláh]— 1 male ( OPC) ; Dalat , Vang River, side tributary, 17.x.1988, sweep net [J. Oláh]— 2 males ( OPC) . Distribution: Vietnam. Etymology: Khoii, named after Nguyen Dong Khoi, the Director of Scientific Research Centre at Dalat, who organized the fieldwork for the collector (J. O.) .
