Laena dentata Xiao-Lin & Guo-Dong, 2012 sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Type material
Holotype ♂ (MHUB): China, Yunnan, Dali, Cangshan E slope, 3400 m, 19 August 2008, J. S. Xu leg.
Paratype: 1♀ (MHUB): labelled as the holotype.
Etymology
Named after anterior tibiae of male with a medial tooth.
Diagnosis
The new species shares with Laena schusteri Schawaller, 2001 the body shape, and the medial tooth of anterior tibia, but can be separated by the teeth of all femora, and middle and posterior tibiae of male with finely hooked inner apex.
Description
Male. Eyes (Fig. 4) elliptical, moderately prominent. Antennae (Fig. 32) extending to base of pronotum, ratio of length (width) of antennomeres II–XI as follows: 7.8 (10.8): 22.1 (11.5): 15.5 (12.8): 16.8 (12.0): 15.0 (13.9): 16.5 (13.9): 15.5 (13.0): 17.8 (13.1): 16.9 (14.2): 20.8 (13.9).
Pronotum (Fig. 4) elliptical, 1.3 times as wide as long, widest at middle; disc with small scattered punctures, their distance 0.5–3 times as long as puncture diameters, all punctures with short and adpressed setae, disc with a pair of feeble impressions, lateral margins narrowly bordered, basal margin unbordered, and not bent downwards, posterior angles rounded; propleura without punctures and setae.
Elytra (Fig. 4) nearly parallel-sided from base to middle, 1.9 times as long as wide, widest at middle; elytra with punctural rows of without striae, punctures distinctly larger than those of pronotum, each puncture bearing a short and adpressed seta, intervals with nearly invisible punctures, but with some similar setae, all intervals flat and shagreened, interval IX with 3 setiferous umbilicate pores.
All femora each with a tooth, but middle femur (Fig. 34) with a pair of equally sized teeth. Anterior tibia (Fig. 33) with median tooth and dilated apex, anterior and middle tibiae excavate medially and with caespitose setae, middle and posterior tibiae (Fig. 35) with finely hooked inner apex.
Last abdominal ventrite (Fig. 36) somewhat sharp at apex. Aedeagus see Figs. 38–40.
