Webbolidia kristenseni , sp. nov.

( Plate 7J , Fig. 451-457 )

Description. Length. Male 10.60 mm., female unknown.

External morphology. Large, robust species. General color light brown to black; forewings light brown, apical 1/7 dark brown, veins black with short, yellow stripes, numerous light brown, irregularly shaped markings in cells; mesonotum black with numerous yellow spots; pronotum black, bullae yellow; crown light brown with short black stripe on each side of middle; eyes dark brown; face light yellow, black longitudinal stripe on inner lateral margins; clypellus with dark brown suffused spot; head narrower than pronotum, anterior margin broadly rounded; crown short, very broad, broader than width of eyes, slightly produced anteriorly, lateral margins convergent basally; eyes large, semiovoid; pronotum very large, nearly twice as long medially as crown, surface bullated; mesonotum large, about half longer medially than pronotum; clypeus long, narrow, lateral margins broadly convex; clypellus short, about 1/ 3 as long as clypeus, narrow, inflated longitudinally along middle, apex strongly flared laterally.

Male genitalia. Pygofer in lateral view very large, broadly triangulate, sparsely setose apically, with caudodorsal lobe, caudoventral margin with small digitate lobe near middle ( Fig. 451 ); aedeagus very long, narrow, tubular, slightly sinuate in dorsal and lateral views, with short, serrated flange near apex, 2 short setae subapically, gonopore distad of middle ( Fig. 452, 453 ); style short, with moderately long apophysis ( Fig. 454, 455 ); dorsal connective moderately long, narrow; connective large, anterior arms broad, somewhat tapered apically, medial ridge incomplete, stem large, ovate ( Fig. 456 ); subgenital plate very long, broad, short spine apically, sparsely setose apically ( Fig. 457 ).

Material examined. Holotype male. THAILAND: Chiang Mai province, Doi Saket , 450 m., 3.xi.1981, Zool. Museum Copenhagen, leg. ( ZMUC) . Paratype, 1 male, THAILAND: 7 km. NW of Fang, Horticultural Experiment Station, 30.xi.-2.xii.1979, Zool. Mus., Copenhagen Exped. ( MLBM).

Etymology. The species is named for Niels Kristensen, Curator of the Hemiptera collection in the Zoology Museum in the University of Copenhagen, Denmark and who was very helpful during my visit there in the fall of 2010.

Remarks. From W. obliquasimilaris to which it is similar, W. kristenseni can be separated by the setal processes arising subapically from the one side of the aedeagus, by shorter apical spine on the subgenital plate and by the presence of the digitate caudoventral pygofer process.
