Diagnosis

Males of Z. logunovi sp. nov. differ from other congeners by a very short embolus directed forward (only Z. schmitzi possesses a similarly short embolus, but in the latter case the embolus is sidewarddirected, cf. Fig. 7 A–D). The ventral brush of setae on the cymbium adjoining the bulb is more welldeveloped than in any other congener (cf. Figs 24 C, 28G–I, 30I). Females are easily distinguished from all other female congeners except Z. annulipes and Z. halepensis sp. nov. by having long, non-divergent median receptacles considerably exceeding the small and globular lateral pair in size ( Fig. 21 ). Females of Z. logunovi sp. nov. differ from those of Z. annulipes and Z. halepensis sp. nov. by the shape of their digitiform (not clublike) median receptacles, which are considerably thinner than in the two latter species (cf. Figs 5 C–D, 9D–F).

Etymology

This species is named after our friend and colleague Dmitri Logunov (University of Manchester, Manchester, UK).

Female (paratype from Kordai)

HABITUS. See Fig. 19 C.

BODY LENGTH. 4.67.

COLOUR. As in male, but darker brownish pattern of carapace is more developed; dorsal abdominal pattern weaker; legs with a few incomplete darker fasciae.

CARAPACE ( Figs 19 D, 42B). 1.78 long, 1.43 wide.

EYES. AME 0.07, ALE 0.17, PLE 0.15, PME 0.10, AME–AME 0.05.

ENDOGYNE ( Fig. 21 ). Both pairs of receptacles cylindrical and with corrugated stems; median receptacles twice as long as laterals and about 1.3 times thinner, median receptacles with wide base and, in anterior view ( Fig. 21 C), both pairs of same diameter; gland pores cover only tips of receptacles.
