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 ).
