Atopolinus uncinatus n. sp.
Material examined:
Holotype ♂: Yunnan, Dali Bai Aut. Pref., Wuliang Shan, 9 km SW Weishan, 2450-2500 m, 25.10N, 100.14E, M. Schülke 13.VI.2007 (cS); paratypes: same data, 1 ♂, 6 ♀ ♀ (cS), 2 ♂ ♂, 2 ♀ ♀ (cB); same data, A. Pütz leg. 13.VI.2007, 1 ♂, 2 ♀ ♀ (cP); 2 ♂ ♂ (one abdomen lost), 1 ♀ (cB); same data, W. Wrase 13.VI.2007, 1 ♀ (cS). GoogleMaps
Description:
Body 7 mm long; length from the antrerior margin of the head to the posterior margin of elytra: 3,5 mm. Brachypterous. Body slender, reddish brown with light humera; antennae and legs yellow-brown. Head ovoid, with largely rounded posterior angles. Eyes very small and almost flat. Surface of the head shiny, with very fine and scattered punctation. Pronotum shiny, slightly longer and narrower than head, with largely rounded anterior angles, sides almost rectlinear, with dorsal series of 8-9 points and lateral series of 6-7 irregular points; other points near the sides of the pronotum. Elytra shorter and scarcely larger than pronotum, with obsolete humera. Surface shiny, feebly rugose, with numerous series of fine and thick punctation. Abdomen with very fine and superficial transversal micro striature and fine punctation.
Sixth visible tergite with posterior margin very peculiar, as in fig. 15 View Figs 12-18 and 6 View Figs 1-11 ° visible sternite as in fig. 16 View Figs 12-18 . Male genital segment symmetrical ( fig. 17 View Figs 12-18 ), with connected basal portion of the pleurae, and sternite as in fig. Aedeagus ( fig. 18 View Figs 12-18 ) with pseudoparameres partially membranous; internal sac with numerous spinules and three big distal spines.
Etymology:
It takes its name from the Latin uncinatus - a- um (hooked) (see the 6° visible tergite).
Bionomy:
“Forest with oaks and pines, in litter” (from the label).
Distribution:
It is known to me only from the type locality.
Notes:
This new species is related to A. subnigroaeneussubnigroaeneus (COIFFAIT, 1982) from Nepal and West Bengala ( BORDONI, 2002) by the general shape of the distal part of the abdomen in dorsal view, but differs by the structure of the 6° visible abdominal segment, pseudoparameres and internal sac of the aedeagus.
Atopolinus inusualis n. sp.
Material examined:
Holotype ♂: Yunnan, Dali Bai Aut. Pref., mnt range N Er Hai, 42 km N Dali, 2500-2550 m, 26.04N, 100.09E, M. Schülke 16.VI.2007 (cS); paratype: same data, 5 ♀ ♀ (cS), 1 ♂, 3 ♀ ♀ (cB). GoogleMaps
Description:
Body 8 mm long; length from the antrerior margin of the head to the posterior margin of elytra: 4 mm. Reddish brown, with antennae and legs testaceous. Head ovoid, with largely rounded posterior angles. Eyes small and slightly protruding. Surface of the head shiny, with two series of three large points between the eyes, and with fine and scattered points, especially on the sides. Pronotum sub rectangular, not dilated anteriorly, longer than head, as large as head, with rounded anterior angles. Surface shiny, with dorsal series of 7-8 points and lateral series of 4 ponts, all similar that those of the head. Elytra short, shorter than pronotum, sub rectangular, with evident humera. Surface shiny, with numerous series of large points. Abdomen with fine transversal microstriation and fine punctation.
Tergite and sternite of the male genital segment as in figs 20-21 View Figs 19-22 . Aedeagus ( fig. 22 View Figs 19-22 ) large (2,2 mm long), sub ovoid, with asymmetrical sub triangular pseudoparameres, partially membranous; internal sac large and long, ribbon-like, covered by evident fine spinules and with some long transversal spines on the distal portion.
Etymology:
It take its name by the Latin inusualis - ee (unusual) (see the shape of the internal sac of the aedeagus).
Bionomy:
“Oaks forest, in litter” (from the label).
Distribution:
It is known to me only from the type locality.
Notes:
This species differs from the congeneric taxa by the shape of the internal sac of the aedeagus.
Atopolinus subtropicalis n. sp.
Material examined:
Holotype ♂: Yunnan, Nujiang Lisu Aut. Pref., Gaoligong Shan, 9 km W Gongshan, 2660 m, 27.45N, 98.34E, W. Wrase 7.VI.2007 (cS); paratype: same data, 1 ♀ (cB). GoogleMaps
Description:
Body 9,5 mm long; length from the antrerior margin of the head to the posterior margin of elytra: 5 mm. Large and shiny species. Black with antennae and legs brown. Pubescence of the body yellow light. Head big, long, dilated backwards, with strictly rounded posterior angles. Eyes small and slightly protruding. Surface of the head with two series of three points between the eyes and with scattered, deep puncturation. Pronotum narrow, longer and narrower than the head, with oblique anterior margins and largely rounded anterior angles, with dorsal series of 11-12 irregular points and lateral sieries of 9-10 irregular points. Elytra sub rectangular, as long as the pronotum, larger than the pronotum, with evident humera, with numerous series of fine puncturation. Abdomen with fine transversal micro striation and fine puncturation.
Sixth visible tergite as in fig. 23 View Figs 23-26 , with characteristic posterior margin; 6° visible sternite with the posterior margin feebly concave. Male genital segment ( fig. 24 View Figs 23-26 ) asymmetric, with sternite as in fig. 25 View Figs 23-26 . Aedeagus ( fig. 26 View Figs 23-26 ) very big (2,33 mm long), with minute and asymmetrical pseudoparameres; internal sac with numerous large spines.
Etymology:
It take its name from the subtropical forest of the type locality.
Bionomy:
“Under stones along pass road” (from the label).
Distribution:
It is known to me only from the type locality.
Notes:
This species is peculiar by the large dimension, the black colouration and the structures of the internal sac of the aedeagus.

Description:
Body 6,5 mm long; length from the antrerior margin of the head to the posterior margin of elytra: 4,5 mm. Head black, pronotum, elytra and abdomen reddish brown with humera yellow red; antennae testaceous; legs yellowish. Body shiny. Head ovoid, dilated backwards, with largely rounded posterior angles. Eyes moderately large and protruding. Surface of the head with two series of three points between the eyes and with very scattered puncturation. Pronotum longer and narrower than the head, with oblique anterior margins and largely rounded anterior angles. Surface with dorsal series of 6 large and scattered points and lateral series of 4 small points. Elytra very large, longer and larger than pronotum, dilated backwards, with evident humera. Surface with three series of large points near the suture and one median series; other points near the epipleural sides. Abdomen with fine transversal micro striation and fine puncturation.
genital segment; 30 sternite of the same; 31 aedeagus (bar scale: 0,1 mm).
Sixth visible tergite and sternite of peculiar shape ( figs 27-28 View Figs 27-31 ). Male genital segment asymmetric, with the right pleura, in dorsal view, provided by a long distal lobule ( fig. 29 View Figs 27-31 ); sternite as in fig. 30 View Figs 27-31 . Aedeagus ( fig. 31 View Figs 27-31 ) large (1,65 mm long), with short pseudoparameres; internal sac with two big and long spines and other less large spines in the median portion.
Etymology:
Dedicated to Michael Schülke, well known specialist in Tachyporinae .
Bionomy:
“Devastated decidous forest with clearings ans shrubs, in litter and wood” (from the label).
Distribution:
It is known to me only from the type locality.
Notes:
This species is closely related to A. asymetricus (COIFFAIT, 1976) from Nepal by the peculiar structure of the male genital segment, but differs by the shape of the 6° visible tergite and sternite and by the aedeagus.
