Senglet, Antoine, 2011, New species in the zelotes tenuis-group and new or little known species in other zelotes groups (gnaphosidae, araneae), Revue suisse de Zoologie 118 (3), pp. 513-559 : 515-516

Zelotes tenuis -group

DEFINITION: The male pedipalp has an embolar radix, an intercalary sclerite and an elevated arched embolar base with a distad-directed embolus. The terminal apophysis has a posterior sclerite connected to the median part of the radix in Z. subterraneus and Z. longipes -groups ( Senglet, 2004: figs 1a, 1d, 12-14), the connection is situated below the base of the embolar radix. The arched embolar base has a variable tooth, which is replaced in Z. manitchensis and Z. alpujarraensis sp. n. by a retrolateral projection. The female has plain lateral epigynal folds enclosing a membranous cuticle. Except for Z. alpujarraensis , the type of ocular group shown in Figs 54-55 is shared by all species of the Z. tenuis -group; the PME are larger or equal to the PLE and separated by 15 to 35% of their diameter. In Z. alpujarraensis the posterior eyes are of equal size, separated by 70% of their diameter.

MATING MECHANISM: In Zelotes tenuis (Fig. 1) and Z. fuscorufus ( Senglet, 2004: 32-34) the apical part of the embolar base is inserted into the posterior segment of the epigynal pocket, putting the embolus in contact with the insemination pore. In Zelotes semirufus (Figs 2-4), however, the proximal apophysis of the embolar base (Figs 2, 11-12) is inserted into the swollen membranous median cuticle of the epigynum (Fig. 3); the broken prolateral hook of the embolar base of Fig. 4 remains inside the cuticle in Fig. 3; the transverse cuticle fold filling the gap between embolus and prolateral embolar base apophysis is visible. The same type of folded median membranous part is found in Z. chaniaensis sp. n. and Z. fulvaster . Figures 5-11 show details of the male bulbus in copula.
