description: Pseudovelia globosa sp. n.
(Figs. 5, 18, 30, 42, 54, 66, 78, 90, 102, 114, 126)
Material examined. Holotype: apterous male, CHINA, Guangdong Prov., Shaoguan city, Nanling Nature Reserve 20 August 2011, 1100 m, Zhen Ye leg (NKUM). Paratypes: CHINA, Guangdong Prov.: 5 apterous males, 7 apterous females, same data as holotype (NKUM).
Description. Apterous male (Fig. 5). Colour: ground colour blackish brown, head almost black, clypeus dark brown; labrum black, rostrum yellowish with black apex, buccula orange; basal part of antennal segment I orange, apical half brown, segments II–IV blackish brown; pronotum dull orange, posterior portion with dense, black spots; legs mainly brown, with apices of femur and tibia weakly infuscated, tarsus blackish brown; abdomen mainly dark brown, connexiva dull orange, lateral portions of mediotergite I, medial portions of mediotergites II, III VI and VIII with prominent silvery pubescence; segment VIII, pygophore and proctiger yellowish, each apically infuscated. Structural characteristics: body length: 2.79–2.83 (holotype: 2.8), medium-sized, rather stout, bearing short, suberect, grayish hairs, areas around the eyes and antennal segment I covered by with relatively long, suberect, grayish hairs. Head short and wide, width: 0.63–0.65, length: 0.34–0.36, head width about 1.83 times head length, relatively perpendicular, posterior margin almost straight; labrum angular, buccula clearly visible, not produced posteriorly; eyes bare except for the presence of two ocular setae; antenna about 0.66 times as long as body, lengths of antennal segments I–IV: 0.61, 0.36, 0.36, 0.53. Pronotum almost rounded, width: 0.82–0.84, length: 0.49–0.51, about 1.66 times as wide as long; bearing dense, dark punctures on posterior part of pronotal lobe, anterior and posterior margins almost straight; metanotum completely hidden beneath pronotal lobe except laterally; fore tibia (Figs. 18, 30) slightly widened apically, with dense, suberect, short hairs, medial portion of venter on fore tibia with slight process, length of grasping comb 0.31, about 0.39 times fore tibial length (Fig. 30); middle leg (Fig. 42) with short, suberect hairs; hind tibia (Fig. 54) straight, hind tarsal segment I (Fig. 66) extremely short, almost globose, basal portion of hind tarsal segment I with a cluster of relatively long, black bristles, ventral arolium bristle-like; lengths of leg segments (femur, tibia and tarsus): fore leg: 0.81, 0.79 and 0.38, middle leg: 1.05, 1.04 and 0.58 (0.15+0.43), hind leg: 1.11, 1.09 and 0.65 (0.13+0.52). Abdomen with mediotergites almost flat, connexival segments IV–VI approximately rectangular, strongly raised; mediotergites II–VI subequal in length; abdominal venter flat, slightly concave medially. Genital segments: relatively small, segment VIII (Figs. 78, 90, 102, 114) about 1.49 times as long as wide, posterior margin with sparse, erect, brown hairs, with sub-square shaped depression ventrally, hind margin of depression with a pair of laminar processes, medial part and lateral part of this depression with clusters of short hairs; lateral part of sub-anterior margin of pygophore (Fig. 126) with a cluster of slender, blackish brown hairs, posterior margin of pygophore with short, relatively dense, brown hairs; proctiger small, with rather blunt apex, posterior margin with rather short, erect, black hairs; paramere symmetrical, small, stick-like, with rounded, widened apex.
Apterous female. Similar to male; body slightly wider than in male, length: 2.79–2.83; structure of head including antenna as in male, head width: 0.62–0.64, head length: 0.34–0.36, head width about 1.8 times head length, antenna about 0.62 times as long as body, lengths of antennal segments I–IV: 0.52, 0.34, 0.37, 0.50; hind margin of pronotum straight, width: 0.81–0.83, length: 0.44–0.46, about 1.8 times as wide as long; fore tibia without grasping comb, hind tibia and tarsus unmodified, venter of hind tibia without row of blackish-brown short spines, hind tarsal segment I extremely short, but not globose, venter of hind tarsal segment I without a row or cluster of black bristles; lengths of leg segments (femur, tibia and tarsus): fore leg: 0.80, 0.73 and 0.40, middle leg: 1.00, 0.98 and 0.58 (0.18+0.4), hind leg: 1.05, 1.1 and 0.6 (0.17+0.43); abdomen pleurally and ventrally without special modifications, connexiva relatively broad, strongly raised, converging posteriorly and touching caudally; end of abdomen raised in lateral view, gonocoxa I elongate, proctiger blackish brown, with dense, short hairs.
Macropterous female and macropterous male: unknown.
Etymology. The specific epithet “ globosa ” (from Latin, meaning rounded or globular) refers to the fact that hind tarsal segment I of the male is extremely short and almost globular.
Diagnosis. The most striking character of P. globosa sp. n. is the form of hind tarsal segment I which is extremely short and almost globose, with a length only about 0.25 times that of hind tarsal segment II (Fig. 66). In addition to above mentioned character, P. globosa sp. n. may be separated from P. e x t e n s a sp. n. by the structure of the medial portion of the fore tibial venter, which is only slightly convex (Fig. 30), and by the absence of a row of 8–10 short, black spines on the lateral portion of the hind tibia; further differences are found in the structure of the venter on abdominal segment VIII (compare Figs. 78, 90, 102, 114 with Figs. 76, 88, 100, 112).
Distribution. China (Guangdong) (Fig. 138).
