Thaumasia senilis Perty, 1833: 192 , pl. 38, fig. 5.

Philodromus senilis ; Walckenaer, 1837: 561.

Type. Male neotype, here designated, from Parque Nacional de Sete Cidades , Brasileira e Piracuruca, Piauí, Brazil [04°03’S, 41°43’W], 29. VI .2007, L. S. Carvalho ( MPEG 15589 ) .

Note. Since no original material of this species exists, due to the loss of Perty’s types after a bombing during the World War II ( Naturhistorisches Museum de Burgergemeinde Bern and Zoologische Staatssammlung München ( ZSM), confirmed by the curators Dr. Christian Kropf and Dr. Roland Melzer, respectively), we here designate a neotype from specimens collected in the type locality (Piauí, Brazil), which is within the area of its natural distribution, to clarify the taxonomic status of the species and for nomenclatural stability .

Diagnosis. The males of T. senilis resemble those of T. oriximina sp. nov. ( Fig. 152) in the rounded apex of the median apophysis (MA), but can be distinguished by the grooved apex of the median apophysis (MA) ( Figs 30, 31), by the presence of a rounded, flattened area on the middle of the EnB ( Figs 32, 33) and by the presence of a notch dividing the apex of the MA in two parts ( Figs 30, 31). The females resemble those of T. oriximina sp. nov. in the projected middle field of epigynum (MF) ( Fig. 154) and by the excavation on the lateral portion at the anterior margin of the epigynum ( Fig. 154), but can be distinguished by the enlarged end of the second copulatory duct (CD2) ( Fig. 27).

Natural history. The male was reported to exhibit a nuptial gift behavior, as in Pisaura mirabilis (see Bilde et al. 2007; Nitzsche, 2011), to court the female during the reproductive period (Paulo Motta, unpublished data).
