Patrera Simon, 1903

Patrera Simon, 1903: 30 , type species: Patrera fulvastra Simon, 1903: 30 ; Petrunkevitch (1911: 505; 1928: 163); Roewer 1954: 544; Bonnet 1958: 3439; Brescovit 1997: 31 ̅36; Dupérré & Tapia 2016: 30 ̅44.

Emended diagnosis. Patrera species can be distinguished by the following characters combination: carapace subrectangular, tracheal spiracle between the middle of the abdomen and the epigastric groove, lateral margin of endites concave, male palp with subtegular projection, prominent in fulvastra and florezi species groups or reduced in philipi species group. Additionally, the latter group is provided with a sclerotized ventral tegular process ( Figs 22E ̅F; 23C̅E; 24E̅G; 25C̅E; 26D̅F; Dupérré & Tapia 2016:30 ̅41, figs 41, 46). Females can be distinguished from Katissa Brescovit and Shuyushka Dupérré & Tapia by having a distinct sclerotized hood situated on the anterior region of the epigynum, which can be triangular, transversal or scape-shaped ( Figs 1F ̅G; 6F̅G; 13F̅G; 14F̅G; 15F̅G; 16F̅G; 17F̅G; 29F̅G; Brescovit 1997: 146, figs 51̅52; Dupérré & Tapia 2016: 30 ̅41, figs 44, 52, 58, 63). Additionaly, Patrera species also can be distinguished from those of Shuyushka by the absence of a ventral patellar apophysis and from those of Lepajan by the presence of chilum (see Dupérré & Tapia 2016:21 ̅29, figs 28̅29, 33̅34, 38̅39; Brescovit 1993:125 ̅128, figs 1̅8).
