DIAGNOSIS: Mastigoproctus differs from Mayacentrum Víquez and Armas, 2006 , Ravilops Víquez and Armas, 2005 , and Thelyphonellus Pocock, 1894 , in the presence of a well-developed carina that extends from the lateral ocelli approximately two-thirds the length of the carapace toward the median ocular tubercle. Mastigoproctus differs further from Thelyphonellus in the presence of a pair of pygidial ommatoids, which are absent in the latter genera, and from Ravilops by the shape and macrosculpture of the pedipalps, which are elongate, punctate, and tuberculate in Mastigoproctus , but short and smooth in Ravilops . Additionally, Mastigoproctus differs from Mayacentrum in the structure of the tergites and sternites. Only the anterior tergites (I–III) are divided medially in Mastigoproctus , whereas all tergites are partially or completely divided in Mayacentrum , and sternites II and III are unmodified or with at most vague lateral swellings in the adult male of Mastigoproctus , whereas sternites II and III are distinctly bilobed in the adult male of Mayacentrum .

Mastigoproctus View in CoL differs from Mimoscorpius Pocock, 1894 View in CoL , as follows. The pedipalp femur of the adult male bears a pair of teeth, one on the retroventral surface and one on the proventral surface, in Mastigoproctus View in CoL whereas only one tooth is present on the proventral surface in Mimoscorpius View in CoL . The pedipalp tibia of the adult male is distinctly longer than wide in Mastigoproctus View in CoL but almost as wide as long in Mimoscorpius View in CoL . The tibiae of legs II–IV each possess a single ventrodistal spur in Mastigoproctus View in CoL whereas two ventrodistal spurs are present in Mimoscorpius View in CoL . The seminal receptacles are short, triangular, and posteriorly directed in Mastigoproctus View in CoL but tubular and kidney shaped in Mimoscorpius View in CoL .

Mastigoproctus View in CoL differs from Valeriophonus Víquez and Armas, 2005 View in CoL , as follows. The tibiae of legs II–IV each possess a single ventrodistal spur in Mastigoproctus View in CoL whereas a ventrodistal spur is present only on the tibia of leg IV in Valeriophonus View in CoL . The pedipalp of Mastigoproctus View in CoL is elongate and without a lobe on the retrolateral surface of the fixed finger, whereas the pedipalp of Valeriophonus View in CoL is short and robust, with a pronounced lobe on the retrolateral surface of the fixed finger. The macrosetae comprising the stridulatory surface of the pedipalp coxa are randomly scattered in Mastigoproctus View in CoL but evenly aligned in Valeriophonus View in CoL .
