Diagnosis

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 , cf. Figs 211–212 ).

Etymology

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

LEGS. Tibia and metatarsus I as in Fig. 128 . 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.

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 , 213–214 . Palpal tibia short cylindrical and spinose ( Fig. 183 ). Palpal organ with embolus tapering and slightly curved ( Figs 213–214 ).

SPINNERETS. See Fig. 284 . 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.

Female

Unknown.

Variation

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.

Habitat

See the corresponding data for A. infuscata sp. nov.

Distribution

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