description: Lupaeus valentinae sp. nov.
Female (Figs. 44–52). Gnathosoma (Figs. 44–46). The length of subcapitulum is shorter than its width. Subcapitulum bearing a peg-like setae on each dorsal edge lateral to the cheliceral trochanters, two pairs of short adoral setae and 4 pairs of simple hg -setae of which hg3 are the longest. The main part of ventral surface of subcapitulum papillated and with transverse rows of lobes near setae hg4 (Fig. 44). The papillae become smaller anteriad and reach to setae hg2. The surface of coxal part of the subcapitulum smooth dorsally. The first palpal segment papillated. The surface of second segment smooth except proximal one third part with papillae. The first palpal segment without setae; the second segment with 6 simple setae; the third segment (tibiotarsus) with 5 hair-like setae, 1 bladder-like seta and three-pointed process (Fig. 45). The dorsal surface of first and second segments of chelicerae with papillae (Fig. 46). The papillae reach across the half of length of second segment.
Idiosomal dorsum (Fig. 47). The surface of dorsal idiosomal shield smooth. The shield with 2 pairs of coarsely setose sensillae (vi and sce) and 6 pairs of simple setae (ve, sci, c1-2, d1 and e1). Setae ve are the longest among simple setae on the shield. Its length is about 1.5 times longer than length of others. Setae f1 and f2 on each side are situated on a poorly sclerotized common platelet bearing lobes and with indistinct borders. Setae f1 is about 1.5 times longer than f2. Dorsal cuticle with long and thin striae which bear numerous small papillae posteriad to setae d1.
Idiosomal venter (Fig. 48). The propodosomal coxal plates medially completely divided and without small median platelet between the posteromedian edges. Each coxal plate with 6 setae. A peg-like seta on the dorsal part of coxae I present. Genital valves with longitudinal rows of papillae and/or lobes of various length. Genital setae (g1–4) subequal in length. Setae g3 situated more laterally to row of setae g1–2 and g4. The genital papillae welldeveloped; the anterior pair slightly larger than posterior. Venter with 5 pairs of setae between hysterogastral coxal plates (excepting setae on coxal plates and genital valves).
Legs (Figs. 49–52). Leg chaetotaxy: trochanters I–IV: 1—1—2—1 sts; basifemora I–IV, 4—6—3—1 sts; telofemora I–IV, 5—5—4—3 sts; genua I–IV, {1 asl, 1 sts}, 3 asl, 4 sts —2 asl, 5 sts —1 asl, 5 sts —2 asl, 5 sts; tibiae I–IV, 1 asl, 1 bsl, 5 sts —1 bsl, 5 sts —1 bsl, 5 sts —1 T, 4 sts; tarsi I–IV, 3 bsl, 1 dep, 1 dtsl, 2 tsl, 19 sts —1 bsl, 1 dtsl, 1 tsl, 18 sts —1 tsl, 16 sts —15 sts. Solenidion on tibia III relatively long and as solenidion on tarsus II distinctly transversely striated. Leg ventral surface with papillae. Dorsal surface of genua, telofemora and tibia I-II smooth. Dorsal surface of rest leg segments with papillae.
Measurements. Length of idiosoma 270; width 190. Length of hypognathum 116; width 130. Length of palps 60. Chelicerae 110. Length of dorsal idiosomal shield 180; width 140. Legs: I 172; II 150; III 175; IV 427 190. Length of setae: ve 35; sci 22; c1 24; c2 17; d1 24; e1 25; f1 28; f2 18; h1 30; h2 42; g 1–4 10–12. Distance between setae: ve–ve 63; sci–sci 48 55; c1–c1 56; c1–c2 23; d1–d1 52; e1– e1 40.
Male and immatures unknown.
Etymology. The new species is named after my mother, Valentina Sergeyenko.
Differential diagnosis. This new species closely resembles L. platygnathos (Bu & Li, 1991) but it differs by the number of solenidia on leg genua I and IV 4—2 (vs. 3— 1 in L. platygnathos). In new species, setae g3 situated more laterally to row of setae g1–2 and g4 (setae g1–4 situated in the common row in L. platygnathos).
Type material. Female holotype, Ukraine, Crimea, Tyup-Tarkhan peninsula, in soil under cereals and wormwoods, 20.VI.2004 (Coll. Sergeyenko, A.L.).
