Description

(based on male only). Habitus (Fig. 1). Elongate, subparallel, moderately convex. Tegument. Dorsally smooth, largely impunctate, only head in frontal furrows and vertex laterally, as well as pronotum base between impressions coarsely punctate. Measurements and ratios. See Table 2. Color. Body anthracite black dorsally and ventrally, antennomeres 2-11, palpomeres and tarsomeres dark red to fire brick red. Microsculpture. Chiefly reduced (not visible); isodiametric on pronotal lateral margins and basal impressions, elytral basal border and striae, transverse-mesh on labrum and abdominal sterna in middle. Lustre. Dorsal and ventral surfaces moderately shiny, prosternal process, metasternum, and abdominal sterna shinier medially. Head (Fig. 2). Longer than wide, slightly narrower than pronotum; disc smooth; eyes as long as 1.2 times length of antennomere 3, tempora minute, ca. 1/5 of length of eye; frontal furrows wide, deep, roughly and coarsely punctate on inside and marginally; vertex with some large, scattered punctures on each side; clypeal suture partly obliterated; mandibles lightly pointed and hooked at apex. Thorax. Pronotal disc slightly convex, mostly smooth, only internal margin at each basal impression with a few coarse punctures; anterior angles rounded, hardly protruded; posterior angles obtuse, slightly protruded outside (Fig. 2). Elytra elongate, with sides narrowed towards base, widened towards apex; shoulders completely rounded; striae well-impressed, both grooved and wide; stria 7 with one preapical setiferous puncture (Fig. 4); intervals impunctate, smooth, 1-3 flat over most extent, 4-9 subconvex; intervals 2 and 8 fused apically; single apical puncture on lateral margin behind both end of stria 7 and junction of intervals 2 and 8 (Fig. 4); umbilicate series with 16 pores on left elytron and 18 pores on right elytron, humeral group of seven pores on both elytra, apical group consists of nine pores on left elytron and eleven pores on right elytron. Hind wings present. Prosternal process with posterior margin rounded. Legs moderately long and slender; metatarsomeres 1-2 setose medioventrally, in addition to lateroventral setae. Abdomen. Terminal sternite 6 distinctly sinuate and bordered on external margin, with two large marginal punctures (Fig. 7). Male genitalia (Figs 8-10). Median lobe of aedeagus long, ventrally bent at an angle of nearly 90˚, dorsally slightly curved to right apically, with apical lamella narrowed before tip, thereupon widened, subquadrate at tip, with a left-sided lobe prominent. Inner sac of aedeagus with a submedial lamella transversely situated, large and well chitinized. Left paramere conchoid, without transverse apophysis, with apical denticle on ventral margin (Figs 8-9, c–d). Right paramere falcate, with apical part protracted, medial part moderately broadened and a hasp at subbasal position (Figs 8-9, b, e).

Etymology.

A noun in the genitive case for the collector of the holotype of this new species, the prominent specialist of Staphylinidae Harald Schillhammer.

Type locality and habitat.

Harald Schillhammer (personal communication) kindly provided us detailed description for the site and time when the holotype of Apophylon schillhammeri sp. n. was collected: "9) SE Kaili, Leishan Co., NE Leishan, E - slope of Leigong Shan, 26°26.59'N, 108°16.53'E, ca. 900 m, Nanmang river at and above Fangxiang village, ca. 15-20 m wide, variably fast flowing, slightly polluted by surrounding farmland. 16.6.2001, leg. Schillhammer & Wang; 10) as 9), gravel banks, large-sized stones (up to 50 cm diameter), with interstitial of fine sand and clay. 16.6.2001, leg. Schillhammer & Wang".

According to this information, the correct GPS coordinates of the type locality are 26°26.59'N, 108°16.53'E, which differ from the data written on the label pinned under the specimen (see "Type material"). In reality, it was an error in the process of printing the labels (Harald Schillhammer, personal communication).

The small river of Nanmang flows into the upper part of the basin of the Qingshui River. The Qingshui enters the Yuan River, which is one of the main tributaries of the Yangtze River in Hunan. Most probably, the species is a hygrophilous upland dweller that lives adjacent to water. Administratively, the type locality is in Leishan County, Qiandongnan Miao and Dong Autonomous Prefecture, south-eastern part of Guizhou Province, China (Fig. 22).
