Hyalojassus elongatus sp. nov.

( Figs 3 E, F, 16A–F)

Male 8.0 mm long, 3.2 mm wide across humeral angles. Color dull orange dorsally, stramieous ventrally except anteclypeus dark brown apically ( Fig. 3 E, F). Structural features ( Fig. 16 A–F) as in H. takensis Evans except as follows. Head in dorsal view with anterior margin distinctly produced medially ( Fig. 3 G). Male pygofer in lateral view quadrate with numerous long setae of various widths on dorsal half; posterior margin with dense group of setae dorsally, few sparse setae more ventrad, and group of short stout setae near posteroventral corner ( Fig. 16 A). Valve completely fused to pygofer, apex acutely produced between subgenital plates ( Fig. 16 A). Subgenital plate oblong, ovoid, lateral margin straight, medial margin broadly rounded, apex subtruncate with few long thin apical setae and few short submedial setae preapically ( Fig. 16 B). Connective bowl-shaped with prominent lateral lobes, oriented vertically with long axis aligned with vertical axis of atrium of aedeagus ( Fig. 16 D). Style with apodeme broad, paddlelike, shorter than apophysis; apophysis in lateral view slender, sinuate, apex acuminate with dorsal preapical tooth ( Fig. 16 C). Aedeagus with dorsal apodeme columnlike, shaft weakly compressed, U-shaped in lateral view; apex with pair of long slender spines crossing each other medially and extended distad; gonopore preapical on posterior surface ( Fig. 16 E, F).

Material examined. Holotype ♂ THAILAND: Loei, Na-Haeo (biostation) 5–12.V.2001, J. Constant & P. Grootaert, light trap [ RISB].

Notes. This species is readily distinguished from H. takensis by the paler coloration of the head and thorax and more elongate body form, as well as by the distinctive male genitalia. The species name, elongatus , refers to the more elongate body of this species in comparison with the type species of the genus.
