Etymology. The epithet is a noun apposition of a local legend in the Dominican Republic, which originated from the European lycanthropy. It makes reference to a man who can tranform into animals.

Diagnosis. Males of Masteria galipote n. sp. resemble those of M. spinosa , M. simla and M. sabrinae n. sp. in having paraembolic apophysis, but differ in the short and tapered embolus and paraembolic apophysis ( Fig. 28B– C ). Females resemble those of Masteria simla and M. spinosa in the bilobed spermathecae with high ectal lobe and short ental lobe, but differs from those of M. simla in the separated lobes and from M. spinosa in the ectal lobe with narrowed duct and rounded apex ( Fig. 28F ).
