( Figs. 3 View FIGURES 1 – 3 , 10, 11, 12 View FIGURES 4 – 12 , 15, 18, 25, 26, 27, 34, 35, 36, 39, 40)

Material examined. Holotype: apterous male, CHINA, Taiwan Prov., Yilan County, Suao town, Wushibi (24°28'N, 121°50'E), 8 June 2013, Zhen Ye leg. ( NKUM). Paratypes: 2 apterous males, 2 apterous females, same data as holotype ( NKUM); 2 apterous males, 3 apterous females, Taiwan Prov., Yilan county, Yuanshan village, Fushan Botanical Garden (24°45'N, 121°36'E), 9 June 2013, Zhen Ye leg. ( NKUM).

Diagnosis. Pseudovelia spiculata sp. nov. is closely related to P. taiwanensis Ye, Polhemus & Bu, 2013 . However, P. spiculata sp. nov. can be distinguished by the venter of hind tarsal segment I with a row of long, black bristles (Fig. 18); lateral portion of male hind tibia bearing a row of short, black spines ( Fig. 12 View FIGURES 4 – 12 ); and by distinct differences in the structure of abdominal ventrite VIII ( Figs. 25, 26 View FIGURES 19 – 27 , 34, 35 View FIGURES 28 – 36 ).

Description. Apterous male ( Fig. 3 View FIGURES 1 – 3 ). Color: ground color brown, head blackish brown, clypeus brown; labrum black, rostrum dark yellow with black apex, buccula brown; basal part of antennal segment I dark yellow, apical part infuscated, segments II–IV blackish brown; pronotum dull orange, with dense, black spots on posterior part; legs mainly yellowish brown, basal part of femora yellowish, apex of femora weakly infuscated, tibiae and tarsi yellowish brown; abdomen mainly blackish brown, connexiva dark orange, lateral portions of mediotergite I, and medial parts of mediotergites II, III, VI and VII with prominent silvery pubescence; abdominal segment VIII, pygophore and proctiger yellowish, each of them apically infuscated. Structural characteristics: body length: 2.01– 2.04 (holotype: 2.03), small-sized, rather stout, bearing short, suberect, grayish setae, area around eyes and antennal segment I covered by relatively few, long, suberect, grayish setae. Head short and wide, relatively perpendicular, width: 0.48–0.51, length: 0.28–0.31, head width about 1.67 times its length; labrum angular, buccula clearly visible, not produced posteriorly; eyes bare except for the presence of two ocular setae; antenna about 0.63 times as long as body, lengths of antennal segments I–IV: 0.37, 0.23, 0.28, 0.40. Pronotum relatively broad, width: 0.63–0.66, length: 0.37–0.40, about 1.67 times as wide as long, with dense dark punctures scattered on posterior part, hind margin almost straight, anterior margin slightly emarginated; metanotum completely hidden beneath pronotal lobe except laterally; fore tibia ( Figs. 10 View FIGURES 4 – 12 , 15) slightly widened apically, with dense, suberect, short setae, medial part of venter with slight process (Fig. 15), length of grasping comb 0.23, about 0.45 times fore tibia length (Fig. 15); middle leg ( Fig. 11 View FIGURES 4 – 12 ) normal, without any modification; hind tibia ( Fig. 12 View FIGURES 4 – 12 ) straight, with dense, short, decumbent setae, lateral portion bearing a row of 5–6 short, black spines ( Fig. 12 View FIGURES 4 – 12 ), venter of hind tarsal segment I with a row of long, black bristles (Fig. 18), ventral arolium bristle-like; lengths of leg segments (femur, tibia and tarsus): fore leg: 0.50, 0.51 and 0.24, middle leg: 0.62, 0.63 and 0.37 (0.12 + 0.25), hind leg: 0.61, 0.70 and 0.46 (0.20 + 0.26); mediotergites almost flat, connexival segments III–VI approximately rectangular and flat; mediotergites II–V subequal in length; abdominal venter flat, slightly concave medially. Genital segments: relatively small, abdominal segment VIII ( Figs. 25, 26 View FIGURES 19 – 27 , 34, 35 View FIGURES 28 – 36 ) about 2.32 times as long as wide, posterior margin with short, sparse, yellowish setae, with an irregularly shaped depression ventrally, hind margin of this depression with a prominently laminar process, which bears spine-like setae medially, lateral part of depression slightly convex, bordered by spine-like setae; lateral part of of pygophore with a cluster of short, brown setae ( Figs. 27 View FIGURES 19 – 27 , 36 View FIGURES 28 – 36 ), posterior margin of pygophore with short, sparse, erect, black setae ( Figs. 27 View FIGURES 19 – 27 , 36 View FIGURES 28 – 36 ); proctiger small, with rather blunt apex, posterior margin with rather short, erect, black setae; parameres symmetrical, small, constricted medially, apical part widened with rounded apex.

Apterous female. Body small-sized, slightly larger than in male, body length: 2.15–2.19; structure of head including antenna as in male, head width: 0.50–0.53, head length: 0.30–0.33, head width about 1.65 times its length, antenna about 0.59 times as long as body, lengths of antennal segments I–IV: 0.37, 0.24, 0.27, 0.40; hind margin of pronotum straight, pronotum width: 0.60–0.63, pronotum length: 0.30–0.33, about 1.97 times as wide as long; fore tibia without grasping comb or ventral process, hind tibia and tarsus unmodified, venter of hind tarsal segment I without a row or cluster of black bristles; lengths of leg segments (femur, tibia and tarsus): fore leg: 0.51, 0.52 and 0.25, middle leg: 0.63, 0.64 and 0.38 (0.12 + 0.26), hind leg: 0.61, 0.71 and 0.48 (0.21 + 0.27); abdominal pleura and venter without special modifications, connexiva slightly raised and widened, converging posteriorly and touching caudally; end of abdomen raised in lateral view, gonocoxa I elongate, proctiger blackish brown, protruded backward, with dense, short setae.

Macropterous male and female: unknown.

Etymology. The specific epithet “ spiculata ” (from Latin, meaning spine) refers to the lateral portion of the hind tibia in male bearing a row of short, black spines.
