T y p e m a t e r i a l: Holotype: " China (Yunnan), Baoshan Pref., Gaoligong Shan nr. Xiaoheisha N. R., 35 km SE Tengchong, 2110 m, 24°50'16"N, 98°45'43"E, (prim. decid. forest, litter, sifted), 30.V./ 4.VI.2007, D. W. Wrase [11] / Holotypus Porocallus wrasei sp.n. det. V. Assing 2007" (cAss). Paratype: " China: Yunnan [ CH 07-11], Baoshan Pref., Gaoligong Shan nr. Xiaoheisha N. R., 35 km SE Tengchong, 2110 m, 24°50'16"N, 98°45'43"E, decid. forest, litter, sifted, 4.VI.2007, M. Schülke" (cSch).
E t y m o l o g y: The species is dedicated to my friend and colleague David Wrase, specialist of Carabidae , who collected the holotype.
D e s c r i p t i o n: Body length 5.6-6.3 mm. Habitus as in Fig. 1 View Figs 1-7 . Coloration: body blackish, with the posterior margin of the elytra and abdominal segment VIII reddish brown; legs, antennae, and maxillary palpi reddish.
Head ( Fig. 2 View Figs 1-7 ) transverse, 1.10-1.15 times as wide as long; punctation extremely dense, coarse, areolate, and well-defined; pubescence short, brownish, inconspicuous, and more or less depressed; eyes large and bulging, slightly shorter than postocular region in dorsal view. Antenna ( Fig. 3 View Figs 1-7 ) slender; antennomeres III approximately twice as long as wide, IV-IX as long as wide or weakly oblong, X approximately as long as wide, and XI somewhat shorter than the combined length of IX and X.
Pronotum ( Fig. 2 View Figs 1-7 ) approximately 1.3 times as wide as long and 1.3 times as wide as head; maximal width approximately in the middle; posterior angles rather well-marked; punctation similar to that of head; pubescence similar to that of head, but somewhat longer, pubescence of midline directed caudad. interstices reduced to narrow ridges, without microsculpture.
Elytra approximately 1.3 times as wide and at suture about as long as pronotum; punctation as dense as, and even coarser than that of head and pronotum; interstices reduced to narrow ridges, without microsculpture, and glossy; pubescence slightly longer than that of pronotum. Hind wings fully developed. Legs rather long and slender; distal third of metatibia weakly bent; metatarsomere I longer than combined length of metatarsomeres II-IV.
Abdomen ( Fig. 4 View Figs 1-7 ) 0.85-0.90 times as wide as elytra; tergites III-V anteriorly with deep impressions, these impressions with extremely coarse and dense punctation; tergite VI- VII without such impression, anteriorly coarsely punctate, but much less so than anterior impressions of tergites III-V; posterior two thirds of tergites III-VII with sparse and rather fine punctation; interstices without microsculpture and distinctly glossy; posterior margin of tergite VII with palisade fringe; posterior margin of tergite VIII distinctly convex.
: posterior margin of sternite VIII strongly convex; median lobe of aedeagus as in Figs
5-6.
: posterior margin of sternite VIII weakly convex; spermatheca as in Fig. 7. View Figs 1-7
C o m p a r a t i v e n o t e s: InthekeyinASSING (2006), the species would key out together with P. tianmuensis ( PACE 1999) . In order to account for the new species, the key is modified as follows:
1 Elytra with conspicuously coarse, dense, and more or less well-defined punctation. ...... 1a - Elytra either with well-defined finer punctation and shiny interstices, or with illdefined, irregular, confluent punctation..............................................................................2 1a Pronotum and elytra with dense and conspicuously suberect to erect pubescence (best visible on lateral margins of pronotum and elytra). Elytra with less defined punctation and with narrower and less glossy interstices ( ASSING 2006: figure 9). Posterior two thirds of abdominal tergites VI-VII more coarsely punctate ( ASSING 2006: figure 10).
: median lobe of aedeagus with apically shorter and less slender ventral process (best visible in lateral view) ( PACE 1999: figures 8-9). Eastern China: Zhejiang province ........... .......................................................................................................... P. tianmuensis (PACE) - Pronotum and elytra with sparse and more or less depressed pubescence. Whole surface of elytra with well-defined punctation and with distinctly glossy interstices ( Fig. 2 View Figs 1-7 ). Posterior two thirds of abdominal tergites VI-VII finely and sparsely punctate ( Fig. 4 View Figs 1-7 ).: median lobe of aedeagus with apically longer and more slender ventral process ( Figs 5-6 View Figs 1-7 ).: spermatheca as in Fig. 7 View Figs 1-7 . Southwestern China: W-Yunnan............... .................................................................................................................. P. wrasei nov.sp.
