Hiatusorus aviformus , sp. nov.

( Plate 3A , Fig. 141-147 )

Description. Length. Male 8.80 mm., female unknown.

External morphology. Large, robust species. General color light to dark brown to black; forewings brown, large black triangulate mark at apex of clavus, transparent area distally, apical 1/5 dark brown, veins interspersed with short yellow and black stripes, cells translucent except at apex, mesonotum black, apex yellow; pronotum black, bullae dark yellow; crown brown; eyes dark brown; face entirely brown; head narrower than pronotum, anterior margin obtusely rounded; crown short, broad, slightly narrower than width of eyes, produced anteriorly about ¼ of entire length, lateral margins convergent basally; eyes large, semiglobular; pronotum large, about half longer medially than crown, surface bullated, mesonotum large, about 1/3 longer medially than pronotum; clypeus long, broad, lateral margins broadly convex; clypellus short, about 1/3 as long as clypeus, narrow, longitudinally inflated medially, apex flared laterally.

Male genitalia. Pygofer in lateral view with long robust caudodorsal process, apex aviform, glabrous ( Fig. 141 ); aedeagus long, tubular, shaft slightly inflated in distal 1/5, in lateral view sinuate, narrow incurvation in apical 1/5, apex toothed, gonopore subapical ( Fig. 142, 143 ); style with moderately long apophysis ( Fig. 144, 145 ); dorsal connective short, narrow ( Fig. 142, 143 ); connective small, anterior arms curved apically, medial ridge incomplete, stem small, subrectangulate ( Fig. 146 ); subgenital plate long, broad, with moderately long, slender apical spine, sparsely setose apically ( Fig. 147 ).

Material examined. Holotype male. LAOS: (Oudomxai), 1-9.v.2002, 1100 m., 20 o 45’N 102 o 09’E., Oudom Xai (17 km. Nee), Vit Kuban, leg / Entomological expedition, “Laos 2002”, Moravian Museum, Brno, Czech Republic ( MMBC).

Etymology. The species name is descriptive for the aviform apex of the caudodorsal process of the pygofer.

Remarks. From H. heidainus Li and Wang to which it is similar in the apex of the pygofer caudodorsal process, H. aviformus can be separated by the broad subgenital plate which is not membranous on the outer lateral margin, not toothed on the margin of the incurvated aedeagus and broader anterior arms of the connective. The crown is much shorter than in H. heidainus .
