( Figs. 105–109View FIGURE 105View FIGURE 106View FIGURE 107View FIGURE 108View FIGURE 109, 138)

Glenognatha spherella Chamberlin & Ivie, 1936: 66  , pl. 17, fig. 154–156. (male holotype and female paratype from Chilapa, Guerrero, Mexico, x.1929, deposited in ZMB 26040, examined); Cabra-García et al. 2014: 1029, figs. 1P, 3E, 4G, 6E, 8F; World Spider Catalog 2015.

Diagnosis. Males of G. spherella  resemble those of G. gloriae  and G. australis  by the prominent Ret2 ( Figs. 106B – CView FIGURE 106) and the absence of anterior tooth ( Fig. 106 AView FIGURE 106). It can be distinguished from the former by the shape of the clypeus in lateral view, which is not projected ( Fig. 105BView FIGURE 105) and from the latter by the smaller size and the coiled embolus tip ( Figs. 109 A –DView FIGURE 109). Females can be easily distinguished from all other Glenognatha  species (except G. boraceia  , G. lacteovittata  and G. florezi  ) by the presence of a postero-lateral cheliceral bulge ( Fig. 106EView FIGURE 106); distinguished from these species by the presence of spermathecae ( Figs. 108 A –EView FIGURE 108).
