TypesHolotype: MLP R. 5441, adult male. Collected by J.A. Scolaro, O.F. Tappari and A. Marcus, 29 November 2008. Paratypes: MLP-R 5442, adult male; MLP-R. 5443, adult female; MLP-R 5444 adult female; JAS-DC 1234 adult male; JAS-DC 1219 adult female. The same data as detailed for the holotype. 
CommentThis species belongs to the patagonicus group (fide LOBO et al. 2010).

Diagnosis. Phymaturus castillensis can be distinguished by a peculiar colour pattern similar to the colour patterns observed in females of some species of the patagonicus clade (Fig. 4a, c). However, from most species, except P. videlai, P. indistictus and P. patagonicus, P. castillensis is considerably isolated geographically by hundreds of kilometers (Fig. 3). From these three geographically closer species, P. castillensis can be differentiated by its pattern of coloration (Figs. 1, 2, 4) as well as the morphological differences detailed in the previous paragraph. In this new species there are no dichromatic differences between the sexes. The new species is a member of the patagonicus group, distinguished from the flagellifer group in having flat imbricate superciliaries rather than being rectangular and non-overlapping; slightly spiny and non-rugose caudal scales in verticilles (as seen among members of the flagellifer group). However, it has also the subocular scale not fragmented and separated from supralabials by two rows of lorilabials, as in most species of the patagonicus group, but not seen in the majority of members of the flagellifer group [SCOLARO & PINCHEIRA-DONOSO 2010]. 
EtymologyThe species name refers to the terra typica where this species is restricted.
