Hiatusorus robustus , sp. nov.

( Plate 3C , Fig. 155-161 )

Description. Length. Male 7.60 mm., female unknown.

External morphology. Moderately large, slender species. General color light brown to black; forewings membranous except for suffused light brown markings apical 1/6, veins black; mesonotum black with small yellow contiguous spots; pronotum black, bullae dark yellow; crown light brown; eyes transparent; face yellow; clypeus with orange, longitudinal stripes on inner lateral margins; clypellus tinged with orange; head narrower than pronotum, anterior margin obtusely rounded; crown short, broad, slightly wider than width of eyes, lateral margins convergent basally; eyes large, semiglobular; clypeus long, narrow, lateral margins broadly convex; clypellus very narrow, slightly tumid longitudinally in middle.

Male genitalia. Pygofer in lateral view very large with long robust caudodorsal process, sparsely setose on ventral margin of process ( Fig. 155 ); aedeagus moderately long, narrow, tubular, incurved in distal 4/5, row of teeth in apical 5th ( Fig. 156, 157 ); style small with short, narrow apophysis, base very broad ( Fig. 158, 159 ); dorsal connective moderately long, very narrow, curved medially in lateral view ( Fig. 156, 157 ); connective small, anterior arms narrow, obliquely truncate apically, medial ridge complete, stem very small, ovate ( Fig. 160 ); subgenital plate long, broad, setose apically ( Fig. 161 ).

Material examined. Holotype male. CHINA: Yunnan, Jinhong , 5.III.1999, river bed, Grootaert, leg. ( IRSNB).

Etymology. The name of the species is descriptive for the large robust caudodorsal process on the pygofer.

Remarks. The combination of the large caudodorsal pygofer process, small connective with narrow, oblique truncate arms, absence of subgenital apical spine will distinguish the species.
