Three new species of the giant vinegaroon genus Mastigoproctus (Thelyphonida: Thelyphonidae) from Mexico

Abstract

The giant vinegaroons of the genus MastigoproctusPocock, 1894 have been the subject of recent investigations aimed at elucidating relationships between their species and their validity. In particular, new data have revealed the presence of new species as well as revalidated species that were previously considered as synonyms of Mastigoproctus giganteus (Lucas, 1835). The genus occurs in southern USA, Mexico and South America. In this paper, we describe three additional new species from Mexico: M. franckei Barrales-Alcalá, sp. nov. from Xilitla, San Luis Potosí, M. xetame Barrales-Alcalá & Francke, sp. nov. from the highlands of Jalisco and M. yalchanchak Barrales-Alcalá & Francke, sp. nov. from La Esperanza, Chiapas. The present contribution raises the diversity of the order Thelyphonida in Mexico to 10 species.
