Part 7. The genus Sphaerobulbus Smetana 2003. Section 2. Zootaxa 1006 (1): 53-64, DOI: 10.11646/zootaxa.1006.1.6, URL: https://biotaxa.org/Zootaxa/article/view/zootaxa.1006.1.6
03C0BB41FFC6304CC769FDD97FB90715.taxon	discussion	Comments. Sphaerobulbus bisinuatus was until now known only from the Diancang Shan near the old town of Dali (some specimens bear only “ Dali ” as the locality, see also above) in Yunnan. The occurrence of the species in Daliang Shan (Meigu and Eriyzuxiang) in southern Sichuan confirms my suspicion that S. bisinuatus may be more widely distributed (Smetana 2003: 73). But the presence of this species in Daliang Shan is of particular interest because another, similar and closely related species, S. abdominalis Smetana, 2003, also occurs in Daliang Shan (type locality: pass 20 km S of Muli [Bowa]). The specimens of the Daliang Shan population of S. bisinuatus agree perfectly with those of the type series from Diancang Shan (Dali), except that they lack the paler apex of the abdomen (i. e. the abdomen is entirely dark), just like that of S. abdominalis. The difference in the coloration of the abdominal apex was used to distinguish these two species (see Smetana 2003: 69, 74), but it became useless now. Specimens of S. abdominalis may be distinguished from those of S. bisinuatus by the distinctly denser punctation of both the head and pronotum (the difference is particularly obvious on the disc of the head), and by the markedly larger aedoeagus. The latter character state seems to be useful, although only one male (holotype) of S. abdominalis is known at present. The length of the aedoeagus of the holotype is 2.6 mm; the length of the aedoeagi of the six males of S. bisinuatus varies between 2.0 – 2.1 mm. It is possible, however, that these two species may turn out, after more material becomes available for study, as two different populations of one species. The specimens from near Eryizuxiang were taken from pitfall traps set in primary forest. Due to a technical problem, the figures showing the apical portions of the aedoeagi of both S. bisinuatus and S. abdominalis in the original descriptions were not quite accurate (Figs. 22 and 26 in Smetana 2003). New illustrations are presented here (Figs. 1, 2).	en	Smetana, Aleš (2005): Contributions to the knowledge of the “ Staphylinus-complex ” (Coleoptera: Staphylinidae: Staphylinini) of China. Part 7.

Sphaerobulbus rex is a member of the “ bisinuatus ­ group ” (Smetana 2003: 69), based on the modification of the basal portions of the first three visible abdominal tergites. It differs from all larger species of the group (S. bisinuatus Smetana, 2003, S. abdominalis Smetana, 2003, S. nagahatai Smetana, 2005), in addition to the differences in the shape of the aedoeagus, by the narrower, rounded head, the narrower pronotum, and by the piceous­black legs.	en	Smetana, Aleš (2005): Contributions to the knowledge of the “ Staphylinus-complex ” (Coleoptera: Staphylinidae: Staphylinini) of China.

Length 14.0 – 19.0 mm. Geographical distribution. Sphaerobulbus businskorum is at present known from the high elevations of mountain ranges of Daxue Shan and Shalui Shan in west­central Sichuan. Bionomics. Nothing is known about the habitat requirements of this species; however, it apparently lives in high mountain habitats, most likely in the upper zone of the montane forest and above the tree line. Recognition and comments. Sphaerobulbus businskorum is the second species of the genus that has spots of yellow or golden tomentose pubescence on the abdominal tergites. The other species (S. brezinai) is apparently endemic to Yulong Shan in northern Yunnan. Sphaerobulbus businskorum differs from S. brezinai easily, in addition to the different shape of the aedoeagus, by the larger and more robust body, by the shinier surface of the fore body (in S. brezinai, the dorsal surface of the head and pronotum bears dense microsculpture), and by the golden spots of tomentose pubescence on visible abdominal tergites 4 and 5 (the spots of tomentose pubescence are yellowish in S. brezinai). Most specimens collected by Murzin are missing numerous appendages, apparently due to the prolonged exposure to the liquid in pitfall traps.	en	Smetana, Aleš (2005): Contributions to the knowledge of the “ Staphylinus-complex ” (Coleoptera: Staphylinidae: Staphylinini) of China.

Black, dull; maxillary and labial palpi dark brunneous to brunneopiceous, antennae piceous­black with first segment vaguely paler, legs brownish­red. Head of rounded quadrangular shape, with entirely rounded, obsolete posterior angles, wider than long (ratio 1.31), eyes small, rather flat, tempora considerably longer than eyes from above (ratio 1.61), dorsal surface of head very densely, moderately finely punctate and pubescent, punctation gradually becoming sparser anteromediad; very narrow, impunctate midline present on posterior half of head; interspaces between punctures without appreciable microsculpture. Antenna short, segment 3 longer than segment 2 (ratio 1.20), segments 4 – 7 longer than wide, becoming gradually shorter, segment 8 about as long as wide, segments 9 and 10 slightly wider than long, last segment shorter than two preceding segments combined. Pronotum about as long as wide, slightly narrowed anteriad, narrow marginal groove disappearing downwards just in front of middle of pronotal length; disc of pronotum with complete, narrow, impunctate midline; punctation and pubescence similar to that on head but slightly finer and even denser, interspaces between punctures without microsculpture. Scutellum finely and densely punctate and setose, more densely so on apical portion, surface with extremely fine, rudimentary transverse microsculpture. Elytra short, not appreciably widened posteriad, at suture considerably (ratio 0.65) at sides distinctly (ratio 0.83) shorter than pronotum at midline; punctation fine and quite dense, finely asperate, interspaces between punctures with fine, dense, granulose microsculpture, elytra therefore appearing dull; pubescence black, dense. Wings each reduced to minute, nonfunctional stump. Abdomen with tergite 7 (fifth visible tergite) lacking pale apical seam of palisade setae; tergite 2 (in front of first visible tergite) entirely, finely and densely punctate; posterior basal line on first three visible abdominal tergites simple, almost straight; all tergites very finely and densely punctate, punctation markedly finer than that on elytra, gradually becoming vaguely sparser toward apex of each tergite and in general toward apex of abdomen; interspaces with extremely fine microsculpture of short transverse striae that become rudimentary toward middle of each tergite; pubescence black, dense. Male. Sternite 8 with moderately wide, rather shallow, obtusely triangular medioapical emargination. Male genital segment with sternite 9 with moderately wide and deep, arcuate apical emargination (Fig. 18). Tergite 10 moderately large, triangular with differentiated apical portion with obtuse apex bearing long apical and subapical setae, otherwise moderately densely setose (Fig. 19). Aedoeagus small and wide, as in Figs. 20 – 22; median lobe short with parallel­sided middle portion, with short, subacute apex; paramere situated on median lobe markedly asymmetrically, with obliquely truncate apex distinctly not reaching apex of median lobe; underside of paramere with a few inconspicuous, not pigmented sensory peg setae, with five long apical setae along left lateral margin and with two minute, stout setae situated in middle of apical portion of paramere below apex (Fig. 21). Length 16.0 – 17.0 mm. Geographical distribution. Sphaerobulbus bicolor is at present known only from the type locality in southern Sichuan. Bionomics. Nothing is known about the habitat requirements of this species. Recognition. Sphaerobulbus bicolor resembles in external characters small specimens of S. yulongmontis (apparently endemic to Yulongshan), but it differs, in addition to the entirely different shape of the aedoeagus, by the shorter antenna, the more rounded head, by the pronotum which is appreciably narrowed anteriad, and by the absence of the microsculpture on interspaces between punctures both on the head and pronotum.	en	Smetana, Aleš (2005): Contributions to the knowledge of the “ Staphylinus-complex ” (Coleoptera: Staphylinidae: Staphylinini) of China.
