Differential diagnosis

Females of A. tonoi sp. nov. can be differentiated from those of all described species of Anyphaena of the pacifica and pectorosa groups by the opposing L-shaped copulatory ducts, and the adjacent genital openings being inside a small longitudinal rectangular atrium ( Figs 46E–F View Fig , 47G–C View Fig ). Central genital openings are also present in females of A. jimenezi sp. nov., but the latter species differs by the moustacheshaped copulatory ducts. Males can be differentiated by the presence of the following features: distal edge of median apophysis with two transparent lamellae and a sclerotized central hook ( Figs 46D View Fig , 47D View Fig ), middle section of ventral tegular projection broad, retrolateral border with a transparent cuticular edge, distal section shaped as a folded lamella. RTA anterior branch rectangular, long and straight, posterior branch lamella-shaped with a middle notch ( Fig. 47C–D View Fig ), and coxal ventral surfaces smooth ( Figs 45E– F View Fig , 46A–D View Fig , 47A–F View Fig ). Ventral tegular projection with broad middle sections and translucent retrolateral edges are also found in males of A. zorynae ( Durán-Barrón et al. 2016: figs 5–6), A. quadricornuta Kraus, 1955 ( Kraus 1955: figs 108–109), A. stigma sp. nov. ( Fig. 50E View Fig ), A. miniducta sp. nov. ( Fig. 32A View Fig ) and A. bermudensis ( Sierwald 1988: fig. 1), these latter two species without the lateral edge. A median apophysis with transparent lamella are present in A. pectorosa , A. fraterna , A. lacka Platnick, 1974 and A. alachua ( Platnick 1974: figs 51–58). Similar RTA are present in A. scopulata F. Pickard-Cambridge, 1900 (Pickard-Cambridge F. 1900: pl. 7 fig. 17), A. simplex O. Pickard-Cambridge, 1894 (Pickard-Cambridge O. 1896: pl. 23 figs 1–2) and A. stigma sp. nov. ( Fig. 50F View Fig ).

Etymology

The species epithet is dedicated to Marcial Antonio Galán-Sánchez, Mexican arachnologist, and current member of the second author’s lab.
