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 ).
