Treatment

Lobrathium kuanicum View in CoL sp. n. ( Figs 228-234 View Figs 228-233 View Figs 234-243 )

Type material:

Holotype ♂: " Taiwan, Kaohsiung Hsien, Kuanshan trail above Kaunshanchi Riv., 2650 m, 21.IV.92, A. Smetana [ T95 ] / Holotypus ♂ Lobrathium kuanicum sp. n., det. V. Assing 2010" (cAss) . Paratype: 1 ♀: same data as holotype (cSme) .

Description:

Body length: 7.5-8.5 mm. Habitus as in Fig. 228 View Figs 228-233 . External characters as in L. spoliatum , except

for the somewhat larger eyes, their length approximately half the distance from posterior margin of eyes to posterior constriction in dorsal view ( Fig. 229 View Figs 228-233 ).

♂: posterior margin of tergite VIII weakly angled in the middle; sternite VII not depressed in the middle, posterior margin almost truncate; sternite VIII with impression of somewhat oblong triangular shape, this impression with very sparse setae, without clusters of peg-setae, posterior excision shallowly concave ( Fig. 230 View Figs 228-233 ); aedeagus of characteristic morphology, apical lobes slender and subapically hooked ( Figs 231-232 View Figs 228-233 ).

♀: posterior margin of tergite VIII strongly and convexly produced in the middle ( Fig. 233 View Figs 228-233 ); sternite VIII not oblong, posterior margin broadly convex, in the middle truncate; lateral sclerites of tergite IX very narrowly separated anteriorly; tergite X obtuse anteriorly, rather slender and acute apically ( Fig. 234 View Figs 234-243 ).

Comparative notes:

From other representatives of the L. stimulansstimulans group, L. kuanicum is readily separated by the morphology and chaetotaxy of the male sternite VIII, the conspicuous shape of the aedeagus, as well as by the shape of the female tergite VIII.

Etymology:

The specific epithet (adjective) is derived from the name of the mountain range where the species is probably endemic.

Distribution and natural history:

The type locality is situated in the Kuanshan, Kaohsiung Hsien, southern Taiwan, at an altitude of 2650 m. The specimens were sifted from moss on large rocks and fallen trees in a primary coniferous forest (mostly fir) with bamboo undergrowth .
