Laosolidia tuberis, sp. nov.

(Plate 3D, Fig. 162-168)

Description. Length. Male 8.50 mm., female unknown.

External morphology. Moderate size, slender species. General color dark brown to black with numerous yellow specks on mesonotum and forewings, veins marked with ivory dashes; head narrower than pronotum, obtusely angulate anteriorly; crown short, narrower than eyes, lateral margins slightly convergent basally; eyes large, slightly elongate ovoid; pronotum large, about 1/3 longer medially than crown, surface bullated, yellow; mesonotum large, longer medially than pronotum; forewings long, narrow, venation typical; clypeus long, slender, lateral margins broadly convex, about twice as long as clypellus; clypellus as in L. complexa.

Male genitalia. Pygofer in lateral view slightly narrow, apex distad of segment X very short, triangulate (Fig. 162); aedeagus in lateral view inflated, constricted medially, with blunt toothed, subapical process near middle of shaft near gonopore, tuft of long setae distad of middle, subapical row of short teeth on dorsal margin, in ventral view inflated near middle on outer lateral margin, triangulate process subapically, gonopore near middle (Fig. 163, 164); style short, configuration similar to L. complexa (Fig. 165, 166); dorsal connective long and narrow (Fig. 163, 164); connective as in L. implicata, except stem narrower (Fig. 167); subgenital plate long, inflated subapically on outer lateral margin, glabrous (Fig. 168).

Material examined: Holotype male. LAOS: 24-29.iv.2001, Khammouan Prov., 18o 07’N, 104o 29’E., Ban Khoun Ngeun, 200 m., Vit Kuban, leg. Entomological Expedition, Moravia Museum, Brno, Czech Republic (MMBC).

Etymology. The name is descriptive for subapical swelling on the outer margin of the subgenital plate.

Remarks. This species is closest to L. longiserrata and can be separated by the tuberous subgenital plate, by the tuft on long subapical setae on the aedeagus shaft and by the overall configuration of the aedeagus.
