Treatment

Pulaeus krama as well as P. longignathos Bu & Li, 1987 were described based on males which were misinterpreted as females. Also, Bu & Li (1987) in the same paper described the female of P. chongqingensis Bu & Li, 1987 . Males and females of the aforementioned species from the Crimea sometimes occur in the same samples. Therefore, I consider P. longignathos syn. nov. and P. chongqingensis syn. nov. as the male and the female of P. k r a m a.

Female ( Figs. 28–35 View FIGURES 28 – 31 View FIGURES 32 – 35 ). Gnathosoma ( Figs. 28, 29 View FIGURES 28 – 31 ). The chaetotaxy of gnathosoma as in P. leonidi sp. nov. Ve n - tral surface of the subcapitulum with transverse rows of lobes behind setae hg4; the surface lateral and anterior to setae hg4 with papillae nearly reaching setae hg2 ( Fig. 28 View FIGURES 28 – 31 ). Dorsal surface of the coxal region papillated. The dorsal surface of the first and proximal half of second cheliceral segments with papillae. Surface of palps almost smooth, except proximal half of second segment covered by papillae ( Fig. 29 View FIGURES 28 – 31 ).The chaetotaxy of palps as in P. leonidi sp. nov. including single ventrally directed pointed process on tibiotarsus.

Idiosomal dorsum ( Fig. 30 View FIGURES 28 – 31 ). The chaetotaxy is typical for genus. Entire surface of dorsal idiosomal shield with transverse rows of lobes. Dorsal cuticle with thin papillated striae. Setae f1 and f2 on each side are situated on a poorly sclerotized common platelet bearing lobes and with indistinct borders. Setae ve are the longest among simple dorsal idiosomal setae. Setae c1-2, d1, e1 and h2 subequal. Setae c1 shorter than distance between setae c1-c2. Setae f1 is about 1.5-1.7 times longer than f2.

Idiosomal venter ( Fig. 31 View FIGURES 28 – 31 ). The borders of coxal plates are distinct ( Fig. 5 View FIGURES 1 – 5 ). The propodosomal coxal plates is medially completely divided and with 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 striae. Genital setae (g1–4) situated in the same row, g4 slightly longer other genital setae. Venter with 6 pairs of setae between hysterogastral coxal plates (excepting setae on coxal plates and genital valves). An unpaired seta sometimes present anteriad to genital opening.

Legs ( Figs. 32–35 View FIGURES 32 – 35 ). Leg chaetotaxy: trochanters I–IV: 1—1—2—1 sts; basifemora I–IV, 4—6—3—2 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 —1 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, 4 bsl, 1 dep, 1 dtsl, 2 tsl, 21 sts —1 bsl, 1 dtsl, 1 tsl, 19(18) sts —16 sts —17 sts. Entire leg surface with papillae, which are dorsally larger but sparser.

Male ( Figs. 36–43 View FIGURES 36 – 39 View FIGURES 40 – 43 ). Gnathosoma ( Figs. 36–38 View FIGURES 36 – 39 ). The gnathosomal constituents (as well as hypognathal and palpal setae) noticeably elongated. The surface of gnathosoma mainly smooth but with few papillae on dorsal surface of the coxal region and on first cheliceral segment. Ventral surface of palps with weakly developed longitudinal striae. The chaetotaxy is the same as in female. Setae hg3 are the longest and setae hg4 are the shortest hypognathal setae.

Idiosoma ( Figs. 39 View FIGURES 36 – 39 ). The chaetotaxy is the same as in female except number of setae between hysterogastral coxal plates ( Fig. 39 View FIGURES 36 – 39 b). There are only 4 pairs of setae (6 in female). Entire surface of dorsal idiosomal shield with transverse rows of lobes ( Fig. 39 View FIGURES 36 – 39 a). Propodosomal coxal plates entirely fused medially Genital opening relatively smaller and shifted towards anal opening. Setae g3 and g4 situated near to each other.

Key to species of the genus Lupaeus of Crimea 3 (based on females only)

1. The length of subcapitulum is greater than its width; ventral surface of subcapitulum mainly smooth except narrow transverse papillated field at hg4 setae level; palpal tibiotarsus with single pointed process; genu of legs I with 3 solenidia; genital setae (g1–4) situated in the same row................................................. L. subterraneus (Berlese, 1916)

- The length of subcapitulum is shorter than its width; ventral surface of subcapitulum mainly papillated; palpal tibiotarsus with three pointed process; genu of legs I with 4 solenidia; setae g3 situated more laterally than the row formed by setae g1, g2 and g4 ................................................................................ L. valentinae sp. nov.

3. Castro & Den Heyer (2009) considered Cunaxoides trepidus Kuznetsov & Livshits, 1979 as Pulaeus , Scutopalus (p. 20) and Lupaeus (p. 28). I consider this species as a member of the genus Scutopalus Den Heyer, 1980 , because setae f2 absent; palp femurogenu with 5 setae and all 6 setae of palp tibiotarsus are simple (no modified bladder-like seta)
