( Figs. 1 , 4, 5, 6 , 13, 16, 19, 20, 21, 28, 29, 30, 37, 40) Material examined. Holotype : apterous male, CHINA , Guizhou Prov ., Libo county, Maolan Nature Reserve, Bake ( 25°16'N , 108°04'E ), 28 July 2013 , Zhen Ye leg. ( NKUM ). Paratypes : 2 apterous males, 3 apterous females, same data as holotype ( NKUM ). Diagnosis. Pseudovelia recava sp. nov. appears to be closely related to P. extensa Ye, Polhemus & Bu, 2013 . However, P. recava sp. nov. can be distinguished from it by the venter of hind tarsal segment I with a cluster of relatively long, black bristles only on basal portion ( Figs. 6 , 16), whereas in P. extensa , the venter of hind tarsal segment I with a row of long, black hairs and the basal portion with a cluster of long, black bristles; distinct differences in the structure of abdominal ventrite VIII ( Figs. 19, 20 , 28, 29 ); and lateral portion of proctiger without a row of relatively long, brown setae.

Color: ground color dull brown, head brown, clypeus dark brown; labrum black, rostrum yellowish with black apex, buccula orange; antennal segment I orange, segments II–IV blackish brown; area behind head along anterior margin of pronotum with a distinctly dark yellow transverse band, posterior part of pronotum with dense, black spots; legs mainly brown, basal part of femora broadly yellowish, apex of femora and tibiae infuscated, tarsus blackish brown; abdomen mainly dull brown, connexiva dull orange, lateral parts of mediotergite I, medial parts of mediotergites II, III, VI and VII with prominent silvery pubescence; abdominal segment VIII, pygophore and proctiger yellowish, each of them weakly infuscated apically. Structural characteristics: body length 2.57–2.61 ( holotype : 2.59), medium-sized, rather stout, bearing short, grayish setae, area around the eyes and antennal segment I covered by relatively long, suberect, grayish setae. Head short and wide, relatively perpendicular, width: 0.57–0.60, length: 0.32–0.35, head width about 1.79 times its length; labrum angulate, buccula clearly visible, but not produced posteriorly; eyes bare except for the presence of two ocular setae; antenna about 0.65 times as long as body, lengths of antennal segments I–IV: 0.50, 0.33, 0.40, 0.46. Pronotum width: 0.78–0.82, length: 0.42–0.45, about 1.78 times as wide as long; hind margin slightly rounded, anterior margin slightly emarginated, dense darker punctures scattered on the posterior portion of pronotal lobe; metanotum completely hidden beneath pronotal lobe except laterally. Fore tibia ( Figs. 4 , 13) with dense, short setae, medial portion of venter with distinct process (Fig. 13), length of grasping comb 0.33, about 0.55 times tibial length (Fig. 13); middle leg ( Fig. 5 ) with relatively long, suberect setae; hind tibia ( Fig. 6 ) straight, with a row of 5– 6 short black spines on lateral part, basal portion of venter on hind tarsal segment I with a cluster of relatively long, black bristles (Fig. 16), ventral arolium bristlelike; lengths of leg segments (femur, tibia and tarsus): fore leg: 0.61, 0.60 and 0.38, middle leg: 0.78, 0.80 and 0.51 (0.20 + 0.31), hind leg: 0.81, 0.95 and 0.70 (0.32 + 0.38); mediotergites almost flat, connexival segments IV–VI approximately rectangular, slightly raised; mediotergites II– VI subequal in length; abdominal venter flat, slightly concave medially. Genital segments: relatively large, segment VIII ( Figs. 19–20 , 28–29 ) about 2.5 times as long as wide, posterior margin with few short, yellowish, erect setae bearing a subtriangular depression ventrally, hind margin of this depression with a pair (1+1) of processes with tufts of very short, dense setae; lateral part of sub-anterior margin of pygophore with a cluster of sparse, yellowish setae ( Figs. 21 , 30 ), posterior margin of pygophore with relatively dense, long, yellowish setae ( Figs. 21 , 30 ); proctiger small, with apex rather blunt; parameres symmetrical, small, twisted, with widened apex.

Similar to male but body slightly wider, body length: 2.60–2.63; structure of head including antenna as in male, head width: 0.59–0.63, head length: 0.38–0.39, head width about 1.53 times its length, antenna about 0.64 times as long as body, lengths of antennal segments I–IV: 0.49, 0.31, 0.41, 0.46; pronotum as in male, width: 0.78–0.81, length: 0.48–0.51, about 1.60 times as wide as long; fore tibia without grasping comb or ventral process, middle leg normal, hind tibia straight, without row of black short spines, basal part of hind tarsal segment I without bristles; lengths of leg segments (femur, tibia and tarsus): fore leg: 0.62, 0.60 and 0.35, middle leg: 0.70, 0.80 and 0.44 (0.14 + 0.30), hind leg: 0.84, 0.92 and 0.54 (0.20 + 0.34); abdominal pleura and venter without special modifications, connexiva broad, almost flat, converging posteriorly and touching caudally; end of abdomen slightly high in lateral view, gonocoxa I elongate, proctiger blackish brown, with dense, short setae. Macropterous male and female : unknown. Etymology. The specific epithet “ recava ” (from Latin, meaning concave) refers to abdominal segment VIII bearing a subtriangular depression ventrally.
