Males of Anemesia parvula sp. nov. differ from those of A. pallida sp. nov. in the shape of the bulb (which is comma-shaped with a weakly convex anterior lobe in the former species, but pegtop-shaped with a strongly bulging anterior lobe in the latter; Figs 213–214 View Figs 206–214 , cf. Figs 211–212 View Figs 206–214 ).


The specific name is derived from the Latin adjective ‘ parvulus ’ meaning ‘small’, and reflects the minute size of the specimens; the gender is feminine.

Male (holotype)

HABITUS. See Fig. 11. View Figs 10–17

MEASUREMENTS. TBL 10.10, CL 4.08, CW 3.46, LL 0.38, LW 0.70, SL 2.04, SW 1.90.

COLOUR. Prosoma, palps and legs pale yellowish orange with slightly darker brownish orange chelicerae, clypeus and radial grooves of carapace; eye tubercle blackish brown; most part of abdomen and spinnerets milky white; dorsal abdominal pattern represented with narrow and interrupted brown longitudinal stripe and five pairs of brownish chevrons posteriorly.

PROSOMA. Clypeus and eye tubercle as in Fig 58 View Figs 48–62 . Eye diameters and interdistances:AME 0.12(0.20), ALE 0.25, PLE 0.12, PME 0.08, AME–AME 0.15(0.07), ALE–AME 0.08(0.04), ALE–PLE 0.10, PLE–PME 0.04, PME–PME 0.44. Cheliceral rastellum consists of ca 20 spikes located in front of fang base and on low mound. Each cheliceral furrow with 7–8 promarginal and 4 small retromarginal teeth. Sternum, labium and maxillae as in Fig. 100 View Figs 99–107 . Sternal sigilla very small, rounded posterior pair set relatively close to sternal edge. Maxillae with approximately 20 cuspules each.

LEGS. Tibia and metatarsus I as in Fig. 128 View Figs 125–132 . Scopula entire and distal on metatarsus I, narrowly divided on tarsi I and II, elsewhere absent. Trichobothria: 2 rows of 7–8 each on tibiae, 12–14 on metatarsi, 10–12 on tarsi, 10 on cymbium. PTC I–II, III and IV with 6–8, 4–6 and 4–5 teeth on each margin, respectively. SPINATION. Palp: femur d4, pd1; tibia d3–4, p2–3, r1, pv4; tarsus d18–20. Leg I: femur d6, pd3, rd3–4; patella p1; tibia p3, pv4, rv3+m; metatarsus p3, v6. Leg II: femur d5, pd3, rd2–3; patella p1; tibia p3, v8; metatarsus p3, v7; tarsus p2. Leg III: femur d5–6, pd3, rd3; patella p3, r1; tibia d1, p3, r3, v8; metatarsus d2, p4, r3, v7; tarsus p8–10, r4. Leg IV: femur d6, p3, r3; patella p2, r1; tibia d1, p3, r3, v9; metatarsus d2, p5–6, r3–4, v10–11; tarsus p10–11, r5–6. Only palpal patella and tarsus I aspinose.

PALP. Tibia, cymbium and palpal organ as shown in Figs 183 View Figs 173–187 , 213–214 View Figs 206–214 . Palpal tibia short cylindrical and spinose ( Fig. 183 View Figs 173–187 ). Palpal organ with embolus tapering and slightly curved ( Figs 213–214 View Figs 206–214 ).

SPINNERETS. See Fig. 284 View Figs 278–290 . PMS: length 0.37, diameter 0.15. PLS: maximal diameter 0.40; length of basal, medial and apical segments 0.73, 0.75, 0.44; total length 1.92; apical segment triangular.




The carapace length is 4.44 in the only paratype male; the colouration, including the dorsal abdominal pattern, looks completely the same as in the holotype and distinctive from that in males of A. pallida sp. nov.

Known only from the type locality in the central part of Tajikistan ( Fig. 372 View Fig ).
