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).
