Lepidophyma cuicateca — JOHNSON et al. 2017 
DistributionMexico (Oaxaca)

Type locality: 1 km SE Santa María Texcatitlán, Municipality of Santa María Texcatitlán, Oaxaca, México (17.704° N, 97.062° W), 1180 m elevation.  
TypesHolotype: MZFC 16419, adult female, on 28 July 2001 by Andrés Alberto Mendoza-Hernández (AMH-075). 
DiagnosisDiagnosis: Lepidophyma cuicateca is most similar to the species of the Lepidophyma gaigeae Group (sensu Bezy and Camarillo, 2002) with which it shares the following characteristics: 1) small body size, 2) absence of tubercular scales on the body, and 3) poorly differentiated caudal whorls and interwhorls. The new species differs from other members of the group, except L. gaigeae, in having the enlarged caudal whorls sep-arated by two complete rings of interwhorls (in L. dontomasi, L. lowei and L. radula, the whorls are separated dorsally by two rows of smaller interwhorls, only one of which is complete across the venter). The new species differs from L. gaigeae in having a higher number of middorsal scales between the occiput to rump (160– 161 vs. 121–155), and by having a lower number of femoral pores (21–27 vs. 31–34). Furthermore the new species is distinguished from the other species except L. lowei, in having a higher number of dorsals. 
EtymologyThe name cuicateca is an adjetive and refers to the type locality, Cañada de Cuicatlán.
