Polypedilum (Uresipedilum) basilarum View in CoL sp. n.
( Fig. 1 View FIGURE 1 )
Type material: Holotype male ( BDN No. 05939): CHINA: Xizang Autonomous Region (Tibet), Zham County, 2400m, 15. VIII. 1987, C. Deng.
Etymology: From Latin basilaris, at the base, refers to the inner setae situated in the base of the superior volsella.
Diagnostic characters: Differs from other members of the subgenus by having the inner setae of the superior volsella situated in the base of apicomedial projection.
Male imago (n = 1)
Total length 2.44 mm. Wing length 1.76 mm. Total length/ wing length 1.39. Wing length /length of profemur 2.39.
Coloration. Head yellowish brown. Thorax yellow, legs uniformly pale yellow. Abdomen yellow laterally and white in the middle.
Head. AR 0.92. Ultimate flagellomere 345 m long. Temporal setae 7; including 3 inner verticals; 2 outer verticals and 2 postorbitals. Clypeus with 10 setae.
Wing ( Fig.1A View FIGURE 1 ). VR 1.28. Brachiolum with 1 seta, R with 17, R 1 with 14, R 4+5 with 30. Squama with 3 setae.
Thorax. Dorsocentrals 15; acrostichals 9, biserial; prealars 4. Scutellum with 4 setae.
Legs. Terminal scale ( Fig.1B View FIGURE 1 ) of front tibia pointed, 36 m long including 10 m long apical spine; spur on median tibiae 57 µm long including 31 m long comb, unspurred comb 26 m long, spur on posterior tibia 62 m long including 29 m long comb, unspurred comb 23 m long. Width at apex of front tibia 42 m, of middle tibia 42 m, of hind tibia 44 m. Lengths (in m) and proportions of legs ( Table 1 View TABLE 1 ):
Hypopygium ( Figs. 1C–F View FIGURE 1 ). Anal tergite bands weak. Anal tergite with 2 strong median setae, laterosternite with 1 seta. Tergite IX acute posteriorly. Anal point 44 m long, slender and parallelsided for entire length. Phallapodeme 65 m long; transverse sternapodeme 42 m long. Gonocoxite 130 m long. Superior volsella 39 m long, with apex nearly straight; base with 12 inner and 1 apical seta, microtrichiae present on dorsal surface, the inner setae arise near the base of the apicomedial projection. Inferior volsella nearly parallelsided and with prominent seta. Gonostylus 107 m long. HR 1.21; HV 2.28.
Distribution: The species is known only from the type locality (Oriental Region) with altitude 2400m a.s.l.
Remarks: The species resembles P. (U.) kibatiense Goetghebuer from Israel and Zaire, but differs in the location of the inner setae of the superior volsella, which arise on the apicomedial projection. The front tibia scale is oval in P. (U.) kibatiense , pointed in the present species.
