Material examined. Holotype: apterous male, CHINA, Zhejiang Prov., Lin’an city, Tianmushan mountain Nature Reserve, Tianmushan, mountain canyon, 2 August 2011, 1000 m, Zhen Ye leg. (NKUM). Paratypes: 3 apterous males, 2 apterous females, same data as holotype (NKUM).
Description. Apterous male (Fig. 1). Colour: ground colour black; head dark blackish-brown, clypeus, pseudocellar spots and median line of head dark brown; labrum black, rostrum dark yellow with black apex, buccula gray brown; antennal segment I brown, apical part dark, segments II–IV blackish brown; inner margin along eyes with prominent silvery pubescence; pronotum black, posterior part with dense, black spots, area behind head along anterior margin with a dull orange narrow band; legs mainly blackish brown, basal part of femur dark yellow, with apex of femur weakly infuscated, tibia and tarsus almost blackish brown; abdominal dorsum mainly black, abdominal venter mainly gray-black, connexiva black, lateral parts of mediotergite I, medial portions of mediotergites I–III and VI–VII and internal parts of laterotergites III–VI with prominent silvery pubescence; segment VIII, pygophore and proctiger yellowish, each of them apically infuscated. Structural characteristics: body length: 1.93–1.96 (holotype: 1.95), small-sized, relatively stout, set with short, grayish, suberect hairs, area around the eyes and antennal segment I bearing scattered, long, suberect, grayish hairs. Head short and wide, relatively perpendicular, width: 0.52–0.54, length: 0.29–0.31, head width about 1.77 times head length; labrum angulate, buccula clearly visible, but not produced posteriorly; eyes bare except for the presence of two ocular setae; antenna about 0.57 times as long as body, lengths of antennal segments I–IV: 0.30, 0.20, 0.22, 0.39. Pronotum relatively broad, width: 0.69–0.71, length: 0.32–0.33, about 2.12 times as wide as long; bearing dense dark punctures scattered on posterior part of pronotal lobe, hind margin of pronotum almost straight, with anterior margin slightly emarginated; metanotum completely hidden beneath pronotal lobe except laterally. Legs with venter of fore tibia (Figs. 14, 26) flat, bearing short, dense setae, length of grasping comb 0.48, about 0.42 times fore tibia length (Fig. 26); middle leg (Fig. 38) with short, suberect hairs; hind tibia (Fig. 50) straight, with dense, short, decumbent hairs, venter of hind tarsal segment I (Fig. 62) with a row of 4–6 relatively long, black bristles, ventral arolium bristlelike; lengths of leg segments (femur, tibia and tarsus): fore leg: 0.55, 0.48 and 0.23, middle leg: 0.68, 0.6 and 0.35 (0.11+0.24), hind leg: 0.69, 0.78 and 0.46 (0.18+0.28); mediotergites almost flat; abdominal venter flat, medially slightly concave. Genital segments: small, segment VIII (Figs. 74, 86, 98, 110) about 2.0 times as long as wide, posterior margin with short, sparse, erect, blackish brown hairs, anterior margin of segment VIII with a pair (1+1) of short, laminar processes and a subtriangular-shaped depression ventrally, lateral margin of this depression with a small, compact row of short setae, anterior and posterior margins respectively with a spine-like seta; posterior margin of pygophore (Fig. 122) with short, sparse, erect, yellowish brown hairs; proctiger small, with apex rather blunt, posterior margin with rather short, erect, brown hairs; paramere symmetrical, small, stick-like, medial part slightly twisted, apical part widened with rounded apex.
Apterous female. Body larger than in male, almost oval, body length: 2.31–2.32; structure of head including antenna as in male, head width: 0.57–0.58, head length: 0.30–0.31, head width about 1.9 times head length, antenna about 0.52 times as long as body, lengths of antennal segments I–IV: 0.33, 0.22, 0.24, 0.40; hind margin of pronotum straight, pronotum width: 0.75–0.76, pronotum length: 0.33–0.34, about 2.2 times as wide as long; legs relatively slender, fore tibia without grasping comb, hind tibia and tarsus not modified, venter of hind tarsal segment I lacking a row or cluster of black bristles; lengths of leg segments (femur, tibia and tarsus): fore leg: 0.60, 0.50 and 0.28, middle leg: 0.70, 0.67 and 0.42 (0.14+0.28), hind leg: 0.80, 0.88 and 0.44 (0.15+0.29); abdomen pleurally and ventrally without special modifications, connexiva slightly raised and widened, converging posteriorly and touching caudally; end of abdomen high in lateral view, gonocoxa I elongate, proctiger black, with dense, short hairs.
Macropterous female and macropterous male: unknown.
Etymology. The specific epithet “ anthracina ” (from Latin, meaning black) refers to the nearly black color of the male and female dorsum.
Diagnosis. P. anthracina sp. n. is similar to P. hirashimai, with both of these two species having similar ground colour and silvery markings. However, P. anthracina sp. n. can be distinguished by having the pronotum about 1/2 as long as wide (in P. hirashimai, the pronotum is about 2/3 as long as wide); hind tarsal segment I about 3/5 the length hind tarsal segment II (in P. hirashimai, the length of hind tarsal segment I is subequal to hind tarsal segment II); the venter of hind tarsal segment I with a row of 4–6 long, black bristles (in P. hirashimai the venter of hind tarsal segment I bears a row of 3 long, black bristles); and differences in the ventral structure of abdominal segment VIII (Figs. 74, 86, 98, 110).
Distribution. China (Zhejiang) (Fig. 138).
