( Fig. 46A–E)

Material examined. UKRAINE: Kiev Province, Korostyshev, 100 km west of Kiev, 1 female, 20.vii.1905, Yu Wagner ( ZMB) .

Diagnostic characters. This taxon is characterized by having very densely hairy wings; the ventrolateral lobe is strongly curved and shaped very differently from all known Pentapedilum females.

Female (n = 1)

Total length not measurable. Wing length 2.82 mm. Wing length / length of profemur 2.43. Brown.

Head. AR 0.37. Temporal setae 10 including 3 inner verticals, 4 outer verticals, and 3 postorbitals. Clypeus with 20 setae. Tentorium 163 µm long. Palpomere lengths (in µm): 60, 45, 50, 42, 72.

Wing. Anal lobe moderately reduced. Brachiolum with 3 setae, RM with 5 or 6, M with 33 setae. Wing membrane densely covered with macrotrichia. Squama with 9 setae.

Legs. Scale on foretibia ( Fig. 46A) 49 µm long, with 45 µm long apical spur. Spurs on midtibia 46 µm long; on hind tibia 50 µm long. Comb on midtibia 24 µm long; combs on hind tibia 25 µm and 23 µm long. Width at apex of foretibia 57 µm; of midtibia 69 µm; of hind tibia 71 µm. Length and proportions of legs as in Table 59.

Genitalia ( Fig. 46B). Gonocoxite IX with 8 setae; tergite IX with 35 setae; segment X with 4 setae. Cercus 105 µm long. Seminal capsule spherical, 104 µm long, 87 µm wide, with 18 µm long sclerotized neck. Notum 149 µm long. Dorsomesal lobe ( Fig. 46D) 87 µm long, 41 µm wide; ventrolateral lobe ( Fig. 46E) brush-like, strongly curved; apodeme lobe as in Figure 46C. Postgenital plate U-shaped.

Remarks. Although the female differs from all other examined females, it could belong to one of the described males. We thus refrain from naming the species.
