(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.

Description. Apterous male (Fig. 1). 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.

Apterous female. 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.
