New morphological, taxonomic and faunistic data on the genus
In recent years, we obtained numerous
The examined material is deposited in the following public collections:
The genitalia and other dissected parts were mounted on plastic slides and attached to the same pin as the respective specimens. Photographs were taken with a Canon EOS 7D camera with a MP-E 65 mm macro lens or with a Canon G9 camera mounted on an Olympus CX31 microscope.
The following abbreviations were used in the text, with all measurements in millimeters:
The type labels were cited with the original spelling; different labels are separated by slashes.
Paratype ♂ [teneral]: “KUATUN FUKIEN, China 21.4.46, (TSCHUNG SEN.) / PARATYPUS,
(9 ♂♂, 6 ♀♀).
The original description was based on three type specimens from Guadun, Fujian (

The original description was based on two type specimens from Min Shan, Gansu (
Holotype ♂: China: Xizang Prov., Linzhi County, Pailong,
Measurements (in mm) and ratios:
Habitus as in Fig.
Head transverse; posterior part of clypeus and vertex distinctly elevated, with indistinct lateral impressions in middle part and semicircular deep impression in front of ocelli, infraorbital ridges slightly impressed; eyes large and convex; small acute postocular ridge situated away from posterior margin of eye; ocelli large; frons smooth and glossy. All antennomeres longer than broad; measurements of antennomeres (length): I: 0.22; II: 0.14; III–VII: 0.16; VIII: 0.13; IX–X: 0.11; XI: 0.19.
Pronotum distinctly transverse; lateral margins finely crenulate and with somewhat regular outline; lateral portions strongly impressed; disc of pronotum with wide, very convex middle elevation and with distinct longitudinal impression; punctation coarse, rather dense in posteromedian portions, sparser in anteromedian and lateral portions, and very irregular and scattered in median portion.
Elytra without distinct longitudinal ridges; suture elevated in posterior two thirds; punctation coarse and arranged in partly irregular series (except in posterior portion of elytra); each elytron with approximately 3 or 4 smooth tubercles. Hind wings present.
Male. Protarsomeres I–IV very weakly dilated; sternites III–VII unmodified; sternite VIII (Fig.
Female. Protarsomeres I–IV not dilated. Abdominal sternite VIII without posterior excision. Otherwise similar to male.
Based on the coloration of the body, 6–8 smooth tubercles of the elytra, the presence of pronounced elevations on the pronotum and elytra, as well as the morphology of the aedeagus, the new species is most similar to
The type locality is situated in Pailong to the northeast of Linzhi, southern Xizang. The specimens were sifted from leaf litter, moss and mushrooms in broad-leaved forests at an altitude of 2100 m (Fig.
Patronymic, named after Xiao-Bin Song, who collected some of the type specimens.
Holotype ♂: China: Hunan Prov., Yizhang County Mangshan N. R.,
Measurements (in mm) and ratios:
Habitus as in Fig.
Head transverse; posterior part of clypeus and vertex moderately elevated, with indistinct lateral impressions in middle part and weak impression in front of ocelli, infraorbital ridges impressed; eyes large and convex; small acute postocular ridge situated away from posterior margin of eye; ocelli large; frons smooth and glossy; antennomeres I–VIII and XI longer than broad; antennomeres IX–X as long as broad; measurements of antennomeres (length): I: 0.17; II: 0.10; III: 0.12; IV–V: 0.11; VI: 0.07; VII: 0.10; VIII–X: 0.08; XI: 0.14.
Pronotum distinctly transverse; lateral margins finely crenulate and with somewhat irregular outline; lateral portions indistinctly impressed; disc of pronotum with wide, very convex middle elevation and with distinct longitudinal impression; punctation coarse, dense in posteromedian portions, rather sparser in anteromedian and lateral portions, and irregular and scattered in median portion.
Elytra without distinct longitudinal ridges; punctation coarse and arranged in partly irregular series (except in posterior portion of elytra); each elytron with approximately three smooth tubercles. Hind wings probably present.
Male. Abdominal sternites III–VII unmodified; sternite VIII (Fig.
Unknown.
As can be inferred from the similar morphology of the aedeagus, the new species is allied to
The type locality is situated in Mangshan to the south of Yizhang, southern Hunan. The specimens were sifted from leaf litter in mixed deciduous forests at an altitude of 1400 m (Fig.
Habitats of
The specific epithet (Latin, adjective: with spines) alludes to the presence of sclerotized spines in the internal sac of the aedeagus.
