Glaberana dentilamina , sp. nov.

( Plate 2C , Fig. 90-96 )

Description. Length. Male 7.60 mm., female unknown.

External morphology. Moderate size, slender species. General color black; forewings, mesonotum and pronotum black without markings; crown brown with black stripe on each side of middle, contiguous anteriorly; eyes ivory; face yellow, without markings; head narrower than pronotum, anterior margin nearly acutely angled; crown narrower than width of eyes, produced anteriorly about 1/3 of entire length, lateral margins convergent basally; eyes large, elongate ovoid; clypeus long, broad, lateral margins broadly convex; clypellus short, about 1/3 as long as clypeus, narrow, apex flared laterally.

Male genitalia. Pygofer moderately large, triangulate, with small caudoventral, digitate lobe, glabrous ( Fig. 90 ); aedeagus long, narrow, tubular, straight in dorsal view, shaft broadly curved in lateral view, basal 1/4 broad, tapered in apical ¾, glabrous ( Fig. 91, 92 ); style small, boot-shape (calceus) in lateral view, apophysis narrow in dorsal view ( Fig. 93, 94 ); dorsal connective long, narrow ( Fig. 95 ); connective small, anterior arms narrow, medial ridge absent, stem sub-ovate ( Fig. 94 ); subgenital plate long, narrow, with row of teeth on inner lateral margin in distal 1/5 ( Fig. 96 ).

Material examined. Holotype male. THAILAND: Phetchabun, Khao Kho NP., Savanna at nursery/ 16 o 52.568’N 101 o 08.104’E., 520 m., pan traps, 6-7.x.2006, / Somchai Chatchumman and Sa-ink Singtong, leg., T797 ( QSBG).

Etymology. The name of the species is descriptive for the toothed subgenital plate.

Remarks. From G. arca (Nielson) to which it is similar in aedeagal features, G. dentilamina can be separated by the much shorter style, presence of a caudoventral lobe of the pygofer and by the row of teeth on the inner lateral margin of the subgenital plate.
