Polypedilum (Uresipedilum) paraviceps Niitsuma, 1992: 703.
Material examined: 2 males, CHINA: Fujian Province, Yongtai County, Light trap. 16. 17. 19. IX. 2002; Z. Liu.
Diagnostic characters: Differs from other members of the subgenus in having a ventral subapical tubercle on the inferior volsella.
Male imago (n = 2, except when otherwise stated)
Total length 2.51–2.70 mm. Wing length 1.32–1.46. Total length/ wing length1.85– 1.90. Wing length /length of profemur 2.04–2.06.
Coloration. Body entirely yellow except pale brown fore tarsi. Wing pale.
Head. AR 1.68–1.73. Ultimate flagellomere 546–599 m long. Temporal setae 9–11; including 3–3 inner verticals; 4–5 outer verticals and 2–3 postorbitals. Clypeus with 13–15 setae. Tentorium 117–120 m long, 26–29 m wide. Palpomere lengths (in m): 29–31; 31–39; 101–120; 101–117; 161–195.
Wing (Fig. 11A). VR 1.21–1.27. Brachiolum with 1 setae, R with 15–16; R 1 with 10– 12, R 4+5 with 20–25. Squama with 5–9 setae.
Thorax. Dorsocentrals 7(1); acrostichals 11–12; prealars 4–4. Scutellum with 9(1) setae.
Legs. Terminal scale (Fig.11B) of front tibia oval, 26–29 m long; spur on median tibiae 44–52 µm long including 23–26 m long comb, un­spurred comb 23–25 m long, spur on posterior tibia 52–55 m long including 26–29 m long comb, un­spurred comb 23–25 m long. Width at apex of front tibia 36–39 m, of middle tibia 42–57 m, of hind tibia 47– 49 m. Lengths (in m) and proportions of legs (Table 11):
Hypopygium (Figs.11C–F). Anal tergite bands fused basal to median anal tergite setae. Anal tergite with 5–6 median setae, laterosternite with 2–3 setae. Anal point broad 40–50 m long, tapering to rounded apex. Phallapodeme 60–75 m long; transverse sternapodeme 30–35 m long. Gonocoxite 100–118 m long. Superior volsella 28–38 m long, strongly projected posteriorly, base with 3 inner setae and 1–2 apical setae; apicomedial projection 30–33 m long, pointed at apex. Inferior volsella 70–75 m long with 17–19 oral setae, not swollen laterally but ventrally with a subapical tubercle bearing one long seta extends caudally. Gonostylus 125–130 m long. HR 0.80–0.94. HV 1.93–2.16.
Distribution: The species is distributed in Japan and Southeast China (Oriental Region).
Remarks: The species resembles P. (U.) aviceps, but differs from the latter as follows: Apicomedial projection of superior volsella much longer in P. (U.) paraviceps; apex of superior volsella strongly projecting posteriorly in P. (U.) paraviceps, straight in P. (U.) aviceps; inferior volsella of P. (U.) paraviceps with subapical ventral tubercle, without in P. (U.) aviceps; oral setae of inferior volsella in P. (U.) paraviceps situated on a tubercle, scattered in P. (U.) aviceps.
In the Chinese material examined, one specimen has a superior volsella (Fig. 11D) with one apical seta but the others have two apical setae (Fig. 11C).
