Two new species of Vaejovis from Mexico


Fernanda Chavez-Samayoa and co-workers have recently described two new species of Vaejovis C.L. Koch, 1836 (Vaejovidae) from Mexico.

Two new species of the genus Vaejovis (C L Koch 1836) belonging to the mexicanus group from Aguascalientes, Mexico, are described and compared to other species closely related to them geographically and morphologically. The species are compared based on the nomenclature and homology proposed by Gonzalez-Santillan and Prendini (2013). An extension of the homology, functionality, and nomenclature of the hemispermatophore proposed by Monod et al. (2017) is applied to vaejovid scorpions for the first time. We provide meristic evidence to support species delimitation and an identification key to the mexicanus species group (Soleglad, 1973) from Aguascalientes. We provide new records that broaden the distribution area, supplement its diagnosis, and expand the description, including details on the hemispermatophore and the telotarsi of Vaejovis tenamaztlei Contreras- Felix et al., 2015.
