Laosolidia longiserrata , sp. nov.

( Plate 3F , Fig. 176-182 )

Description. Length. Male 8.20 mm., female unknown.

External morphology. Moderate size, slender species. General color dark brown with numerous tiny, yellow specks on forewings, veins marked with ivory dashes; head narrower than pronotum, anterior margin obtusely angled; crown narrower than width of eyes, slightly produced anteriorly, lateral margins convergent basally; eyes large, semiglobular; pronotum large, slightly longer medially than crown, surface with yellow bullae; mesonotum large, nearly twice as long medially as pronotum; forewings long, narrow, venation typical; clypeus long, narrow, lateral margins broadly convex; clypellus short, about 1/3 as long as clypeus; clypellus as in L. implicata .

Male genitalia. Pygofer in lateral view elongate, small lobe apically ( Fig. 176 ); aedeagus in lateral and dorsal views with shaft inflated except subapically, in lateral view with long row of teeth on dorsal margin, apex curved laterally with subapical process ( Fig. 177, 178 ); style short, apophysis digitate ( Fig. 179, 180 ); dorsal connective long, narrow ( Fig. 177, 178 ); connective large, triangulate ( Fig. 181 ); subgenital plate long, broad throughout except in apical 1/5, reduced to pendulate lobe, few short microsetae apically ( Fig. 182 ).

Material examined. Holotype male. LAOS: 24-29.iv.2001, Khammouan Prov., 18 o 07‘N, 104 o 29‘E., Bhan Khuoun Ngeun, 200 m., Vit Kuban, leg. Entomological Expedition, Moravian Museum, Brno ( MMBC).

Etymology. The name of the species is descriptive for the long row of teeth on the dorsal margin of the aedeagal shaft.

Remarks. This species can be easily separated from its congeners by the pendulate apex of the subgenital plate and by the long row of teeth on the dorsal margin of the aedeagus.
