Glenognatha australis ( Keyserling, 1883)  

( Figs. 100–104 View FIGURE 100 View FIGURE 101 View FIGURE 102 View FIGURE 103 View FIGURE 104 , 135 View FIGURE 135 )

Pachygnatha australis Keyserling, 1883: 211   (syntypes from Pacasmayo , Peru, deposited in BMNH, examined through photographs of the habitus and male genitalia).  

Glenognatha australis: Simon, 1894: 716   ; Cabra-García et al. 2014: 1029, figs. 1D, 2D, 5E, 7D, 9 A –B; World Spider Catalog 2015.

Diagnosis. Males of G. australis   resemble those of G. gloriae   and G. spherella   by the prominent Ret2 ( Figs. 101B– C View FIGURE 101 ) and the absence of anterior tooth ( Fig. 101 A View FIGURE 101 ). It can be distinguished from the former by the shape of the clypeus in lateral view, which is not projected ( Fig. 100F View FIGURE 100 ) and from the latter by the bigger size and the uncoiled embolus tip ( Figs. 104E–F View FIGURE 104 ). Females resemble those of G. vivianae   by the bean-shaped spermathecae, but are distinguished from the latter by the enlarged Prt2 ( Fig. 101D View FIGURE 101 ).

Description. Male and female described by Keyserling (1883). Additional data.

Specimens from southern Brazil and Argentina exhibit a different coloration pattern ( Figs. 100E–L View FIGURE 100 ).
