Other common names: Dark Mexican Shrew
Taxonomy. Cryptotis griseoventris H. H. T. Jackson, 1933 View in CoL , “ San Cristobal [= San Cristobal de las Casas] , altitude 9500 feet [= 2896 m], State of Chiapas, Mexico.”
Cryptotis griseoventris is in the C. goodwini group based on morphological data, but genetic data are needed to validate this. Based on forefoot morphology, C. griseoventris is closest to C. goodwini . Populations now attributed to C. mam were previously attributed to this species. Monotypic.
Distribution. Highlands of Los Altos de Chiapas, C Chiapas (SE Mexico); possibly also Las Margaritas, E Chiapas, although these specimens might be attributed to Merriam’s Small-eared Shrew (C. merriamz). View Figure
