description: Pseudovelia shaanxiensis Li, Bu & Ye sp. nov.
(Figs. 5, 11, 21, 27, 33, 39, 45, 51, 57, 63)
Material examined. Holotype: apterous male, CHINA, Shaanxi Prov., Hua County, Shaohuashan National Forest Park, 15 August 2015, Zhen Ye leg (NKUM). Paratypes: CHINA, Shaanxi Prov.: 2 apterous females, same data as holotype (NKUM).
Diagnosis. The genital segments (Figs. 39, 45, 51, 57, 63) of P. shannxiensis sp. nov. are quite similar to those of P. tibialis tibialis Esaki & Miyamoto, 1955. However, P. shannxiensis sp. nov. can be distinguished by the process on hind tarsal segment I (Fig. 33) and the anterior margin of the middle tibia (Fig. 27) without a tuft of stout bristles.
Description. Apterous male (Fig. 5). Color: ground color dark-brown, head black, clypeus brown, rostum yellowish-brown with black apex, buccula dark-brown; antennal segment I yellowish-brown, apical part infuscated, segments II–IV brown; pronotum yellowish-brown, with dense black spots on posterior part, lateral part of metanotum black; legs (Figs. 21, 27, 33) mainly yellowish-brown, femora yellowish, apical part of femora infuscated, tibiae and tarsi yellowish-brown, grasping combs brown; mediotergites black, connexiva black with dull-orange margin, lateral part of mediotergite I, medial parts of mediotergites II, III, VI, VII and lateral margins of connexival segments I–V with prominent silvery pubescence; abdominal segment VIII (Figs. 39, 51), pygophore (Fig. 63) and proctiger pale-yellowish, each of them weakly infuscated apically. Structural characteristics: body small-sized, relatively stout, oval-like, bearing short, grayish setae, area around eyes and antennal segment I covered by relatively few, longer, grayish setae, outer margin of eyes covered by relatively dense, short, silver pubescence. Head short and wide, relatively perpendicular to thorax, without inflection; buccula not produced posteriorly; eyes bare except for the presence of two ocular setae. Pronotum relatively broad, bearing dense, dark punctures on the posterior portion of lobe, anterior and hind pronotal margins nearly straight; metanotum completely hidden beneath pronotal lobe except laterally. Fore tibia (Fig. 21) with widened apex, covered with dense, short, brown setae, medial part of venter on fore tibia with slight process, grasping comb relatively thin; middle femur (Fig. 27) covered with dense, short, grayish setae, middle tibia covered with dense, short, brown setae and few, long, suberect, brown hairs; hind tibia (Fig. 33) slightly curved, covered with dense, suberect, brown and bristle-like setae, apical part of lateral margin of hind tarsal segment I with a tuft of suberect, long, black bristles, apical part of hind tarsal segment I with a distinct process (Fig. 33), ventral arolium bristle-like. Abdomen almost flat, connexiva slightly raised, with suberect, few, long and brown setae; abdominal venter flat. Genital segments: small, segment VIII (Figs. 39, 45, 51, 57) relatively stout, about 2.0 times as long as wide, hind margin with a very few, long, brown, suberect setae, ventrally with subtriangular depression, hind margin of the depression with a tuft of short, bristle-like setae; lateral margin of depression with a pair of bristle-like setae, longitudinal midline of the depression bearing a row of short setae apically; hind margin of pygophore (Fig. 63) with very short, erect, yellowish setae; proctiger small, hind margin with dense, short, yellowish setae; parameres symmetrical, small, with widened apex.
Apterous female (Fig. 11). Color: similar to male. Structural characteristics: body small-sized; structure of head including antenna as in male; hind margin of pronotum straight; fore tibia without grasping comb, hind tibia and tarsus not modified, venter of hind tarsal segment I lacking black, long bristles; abdomen pleurally and ventrally without special modifications, connexiva slightly raised, converging posteriorly and touching caudally; end of abdomen raised in lateral view, gonocoxa I elongate, proctiger brown, with dense, short hairs.
Macropterous female and macropterous male: unknown.
Measurements. Apterous male. Body length: 2.00, head width: 0.51, head length: 0.30, head width about 1.70 times head length; antenna about 0.60 times as long as body, length of antennal segments I–IV: 0.33, 0.24, 0.25, 0.38; pronotum width: 0.70, pronotum length: 0.35, about 2.00 times as wide as long; length of grasping comb 0.25, about 0.50 times tibial length; length of leg segments (femur, tibia and tarsus): fore leg: 0.50, 0.56, 0.30, middle leg: 0.79, 0.83, 0.54 (0.18+0.36), hind leg: 0.73, 1.00, 0.69 (0.19+0.50). Apterous female. Body length: 2.31–2.33, head width: 0.53–0.55, head length: 0.30–0.31, head width about 1.77 times head length; antenna about 0.52 times as long as body, length of antennal segments I–IV: 0.36, 0.25, 0.25, 0.36; pronotum width: 0.72–0.75, pronotum length: 0.33–0.34, about 2.21 times as wide as long; length of leg segments (femur, tibia and tarsus): fore leg: 0.56, 0.51, 0.30, middle leg: 0.74, 0.73, 0.44 (0.13+0.31), hind leg: 0.81, 0.93, 0.48 (0.15+0.33).
Etymology. The specific epithet is derived from the name of the type locality, Shaanxi Province, China.
Distribution. China (Shannxi) (Fig. 65).
