Guafo Island Long-clawed Mouse

Geoxus lafkenche

French: Géoxus de Guafo / German: Guafo-Langkrallenmaus / Spanish: Raton topo de Guafo

Taxonomy. Geoxus lafkenche Teta & D’Elia, 2017 , Punta Weather, Guafo Island, Region de Los Lagos, Chile.

Geoxus lafkenche was erected as a distinct species mostly based on cytochrome-b differences against mainland populations of Geoxus . Morphological differences are subtle and based on two specimens. A proper comparison with the form chiloensis from neighboring Chiloé Island was not performed. In this context, validity and nomenclatorial implications of lafkenche remain debatable. Monotypic.

Distribution. Guafo I (SW of Chiloé I), Chile. View Figure
