Hiatusorus supraspinosus , sp. nov.

( Plate 3B , Fig. 148-154 )

Description. Length. Male 9.00 mm., female unknown.

External morphology. Large, somewhat narrow species. General color brown to black; forewing translucent pale brown throughout; mesonotum black with dark yellow markings; pronotum black, bullae dark yellow; crown dark yellow with short black stripe on each side of middle; eyes dark brown; face yellow with orange longitudinal stripe on inner lateral margins; clypellus tinged with orange medially; head narrower than pronotum, anterior margin broadly rounded; crown short, very broad, wider than width of eyes; eyes large, elongate ovoid; pronotum very large, nearly twice as long medially as crown, surface bullated; mesonotum large, abut 1/3 longer medially than pronotum; clypeus long, broad, lateral margins broadly convex; clypellus narrow, slightly inflated longitudinally on middle, lateral margins slightly convergent apically.

Male genitalia. Pygofer large, sub globular except caudodorsal process, process very long, sharply pointed, sparsely setose ( Fig. 148 ); aedeagus very long, tubular, broad in basal half in dorsal view, narrow, slightly sinuate in lateral view; incurvated in distal 1/6 on dorsal margin, with patch of small teeth on dorsal margin, gonopore within distal 2/6 ( Fig. 149, 150 ); style small, moderately long apophysis ( Fig. 151, 152 ); dorsal connective moderately long, narrow ( Fig. 149, 150 ); connective large, anterior arms very narrow; medial ridge complete, stem small, sub-ovate ( Fig. 153 ); subgenital plate very long, robust, with prominent subapical spine on inner lateral margin, moderate long spine apically ( Fig. 154 ).

Material examined. Holotype male. THAILAND: Chiang Mai, Doi Chiang Dao NP Nature trail. / 19 o 24.278’N 98 o 55.311’E., Malaise trap, 10-17.iii.2008. / Songkran and Apichart, leg. T3155 ( QSBG).

Etymology. The name of the species is descriptive for the large subapical spine on the subgenital plate.

Remarks. This species is unique and can be distinguished from all members assigned to the genus by the large subapical spine on the subgenital plate.
