( Figs 73-79 ) Type material: Holotype : " Taiwan - Hsinchu Co., Wufeng , Rd. 122, km 19, 1200 m , mountain forest litter, 26.III.2008 , leg. Vít [12] / Holotypus  Neosclerus inarmatusinarmatus sp. n. det. V. Assing 2009" (cAss). Figs 73-79: Neosclerus inarmatusinarmatus sp. n. : habitus ( 73 ); forebody ( 74 ); male sternite VII ( 75 ); male sternite VIII in ventral view ( 76 ); male sternite VIII in lateral view ( 77 ); aedeagus in lateral view ( 78 ); aedeagus in ventral view ( 79 ). Scale bars: 73: 1.0 mm; 74: 0.5 mm; 75-79: 0.2 mm. Description: Body length 3.4 mm . Habitus as in Fig. 73 . External morphology as in N .. configensconfigens (see below), except as follows: Head with denser puntation; postocular region shorter, almost obsolete. Elytra slightly longer, approximately 0.75 times as long as pronotum ( Fig. 74 ). : sternite VII with very weakly concave posterior margin, in posterior median portion with somewhat denser, but otherwise unmodified pubescence ( Fig. 75 ); sternite VIII with broadly V-shaped posterior excision, its depth approximately 1/6 the length of sternite, in anterior half with median elevation, this elevation without posterior spinose extension ( Figs 76-77 ); aedeagus of distinctive morphology, ventral process subapically weakly dentate in lateral view ( Figs 78-79 ). Etymology: The name (Latin, adjective: unarmed) refers to the absence of a posterior spinose extension of the median elevation of the male sternite VIII, a character distinguishing N .. inarmatusinarmatus from other micropterous species known from Taiwan . Comparative notes: This species is distinguished from other micropterous congeners distributed in Taiwan by the denser punctation of the head, the practically obsolete postocular region, the longer elytra, the morphology of the aedeagus, and by the absence of an anterior carina with posterior process on the male sternite VIII. Distribution and bionomics: The type locality is situated in Hsinchu Hsien , northwestern Taiwan , where the holotype was sifted from mountain forest litter at an altitude of 1200 m in March .
