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 GoogleMaps .2007, L. S. Carvalho ( MPEG 15589 View Materials ) .

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mirabilis (see Bilde et al. 2007; Nitzsche, 2011), to court the female during the reproductive period (Paulo Motta, unpublished data).
