Females

(Females of the spinimana, beshkentica and maracandica species groups can be confidently distinguished from each other only by the shape of the receptacles, but this feature is not a group-specific character).

1. Intensely brown-coloured spiders; abdomen uniformly brown; legs always with darker though diffuse fasciae (Figs 5 A–B, 6A, 8E–G, 10A–E, 11A–E, 12A–B, D–E) ……………………………………2

– Pale yellowish-coloured spiders; abdomen pale yellow or yellowish-grey, with or without darker dorsal pattern; legs often uniformly pale without darker fasciae (Figs 14 A–D, 15A–B, 16C, 17A–B, 18A, 19A–D, 22A–G, 26A, 27F, 29A–H, 30A–B, 31A, 34A, C–D, 35K, 36A–C, 38A–D, 39A–C, 41A–C) ……………………………………………………………………………………………………3

2. Legs I–IV with broader and less contrasting fasciae (Figs 5 A–B, 6A); receptacles as in Figs 5 C–D, 7E–K ……………………………………………………………………………… schmitzi -group

– Legs I–IV with narrower and more contrasting fasciae (Figs 8 E–G, 10A–E, 11A–E, 12A–B, D–E); receptacles as in Figs 9 D–F, 11F–G, 12G–I ……………………………………… annulipes -group

4. Median receptacles tubular, not diverging laterally and always considerably longer than lateral pair (Fig. 21) …………………………………………………………………………… logunovi- group

– Median receptacles often rounded, of same size or even shorter than lateral pair (Figs 26 B–C, E, 27H–I, 30C–E, 33A–B, D, 35E–J, 38E–I, 40, 41I –M); if longer, they diverge laterally as in Figs 25, 29 I–K, 36D–E ………………………………………………………………………………………5
