Genus Stenoterommata Holmberg, 1881

Stenoterommata Holmberg, 1881: 125 . Type species by original designation, Stenoterommata platensis Holmberg, 1881 . Raven, 1985: 106; Goloboff, 1995: 57; World Spider Catalog, 2016.

Ctenochelus Mello-Leitão, 1923: 61 . Type species by original designation, C. maculatus Mello-Leitão, 1923 . First synonymized by Guadanucci & Indicatti, 2004: 256.

Emended diagnosis. Males of Stenoterommata differ from those of Bayana , Neostothis Vellard, 1925 , Psalistopoides , Pselligmus Simon, 1892b , Prorachias Mello-Leitão, 1924 , Pycnothele and Rachias by the rigid and smooth (and usually longitudinal) parallel keels of the embolus ( Figs 19, 21, 22 View FIGURES 17 – 28 , 56–58 View FIGURES 56 – 64 ; Indicatti et al., 2008a, fig. 27), and tibia I with a sessile apical retrolateral megaspine ( Figs 32 View FIGURES 29 – 40 , 61 View FIGURES 56 – 64 ; Goloboff, 1995, figs 72K, 73F; Indicatti et al., 2008a, fig. 28). Females differ from those of Prorachias , Pselligmus , Pycnothele by the absence of scopulae on tibia I, II; from Rachias by the labium wider than long, maxillary posterior heel not produced ( Goloboff, 1995, figs 71A, 72B), and without long, curved setae covering the cuspules. In addition, it also differs by the triangular apical segment of the PLS, and by having a row of enlarged pumpkiniform spigots along the inner edge of the PLS spinning field ( Figs 38, 40 View FIGURES 29 – 40 ), in conjunction with well-developed preening combs ( Goloboff, 1995, fig. 8) on the female metatarsi II, and numerous maxillary cuspules ( Fig. 29 View FIGURES 29 – 40 ; Goloboff, 1995, figs 71A, 72B, E), usually over 40, up to 160 ( Goloboff, 1995).
