Polypedilum (Pentapedilum) robusticeps (Guha et Chaudhuri) View in CoL comb. n.
( Fig. 29)
Pentapedilum robusticeps Guha et Chaudhuri, 1985: 195 View in CoL .
Material examined. INDIA: West Bengal, Palasi , paratype male, 18.viii.1986, S. Chattobadhyay ( ZSM) ; West Bengal, Bastar , paratype male, 7.iv.1980, S. Ahmed ( ZSM) .
Diagnostic characters. Among species with numerous setae on the wing membrane, uniformly colored abdomen, foretibial scale without spur, base of superior volsella without microtrichia and with 4–5 inner setae, the species can be distinguished by having the lateral seta of the projection of the superior volsella placed basally, scutellum with 25–27 setae, and brachiolum with 7–8 setae.
Male (n = 2)
Total length not measurable; 3.24 mm according to Guha and Chaudhuri (1985). Wing length 1.83–2.00 mm. Wing length / length of profemur 1.95–2.18. Brown.
Head. AR 1.98 (1). Ultimate flagellomere 813 (1) µm long.
Thorax. Acrostichals 14, dorsocentrals 34–39, prealars 4. Scutellum with 25–27 setae.
Wing ( Fig. 29A). Anal lobe well developed. VR 1.18–1.43. Brachiolum with 7–8 setae, R with 59–62, R 1 with 79–86, R 4+5 with 77–87, Sc with 58–69, RM with 1–3, M with 19–22, M 1+2 with 65–85, M 3+4 with 31–63, Cu with 34–72, Cu 1 with 24–26, PCu with 97–124, An with 32–35 setae. Cells r 4+5, m 1+2, m 3+4, cell m basal of RM and cu plus an each with numerous macrotrichia. Squama with 9–14 setae.
Legs. Scale on foretibia ( Fig. 29B) 45–48 µm long, rounded, without apical spur. Spurs on midtibia 66–70 µm long, on hind tibia 66–69 µm long. Comb on midtibia 25–30 µm long, combs on hind tibia 14–32 µm and 29–30 µm long. Width at apex of foretibia 57–61 µm, of midtibia 51–55 µm, of hind tibia 62–69 µm. Length and proportions of legs as in Table 37.
Hypopygium ( Fig. 29E). Tergite IX with 14–15 median setae, laterosternite IX with 5 setae. Anal point stout, 76–90 µm long, 18–19 µm wide at base, nearly parallel-sided towards 17–18 µm wide, blunt apex. Transverse sternapodeme 39–57 µm long; phallapodeme 100–120 µm long. Gonocoxite 183–212 µm long. Superior volsella ( Fig. 29C, D) 57–67 µm long, base bare with 4–5 inner setae, projection may be slightly curved at apex, with 1 lateral seta. Inferior volsella ( Fig. 29F) 86–99 µm long.
Remarks. The AR is 1.98, not 3.00; the HR is higher than 1.00, not 0.57, as stated by Guha and Chaudhuri (1985). Their illustration of the hypopygium is also inaccurate and it is not impossible that their type series were mixed.
Distribution. Only known from India.
