Rondon’s Tuco-tuco

Ctenomys rondoni

French: Tuco-tuco de Rondon / German: Rondénia-Kammratte / Spanish: Tuco tuco de Rondonia

Taxonomy. Ctenomys rondoni Miranda-Ribeiro, 1914 ,

type locality not given. Identified byJ. Moojen in 1955 as “Maria de Molina” (= Campos dos Palmares de Maria Molina), Vilhena, Rondoénia State, Brazil, 12° 07’S, 60° 28’W.

There is uncertainty regarding the proper classification of C. rondoni. It was described based on only two specimens, and exact type locality is uncertain. Moreover, the recorded type locality is near that of C. bicolor. Thus, C. rondoni and C. bicolor might be the same species. Karyotype and sperm form of C. rondoni are unknown. Monotypic.

Distribution. SW Brazil, known only from two sites, the type locality in Rondonia and Juruena (Mato Grosso State)Descriptive notes Head-body ¢.230 mm, tail ¢.80 mm. No specific data are available for body weight. Rondon’s Tuco-tuco is medium-sized. Dorsal hairs are pale at bases and sepia at tips. Head and venterare slightly rufous, and tail is uniform brown. Skull is robust and depressed. Inter-maxillaries are also robust, with lateral protruding expansion; maxillaries are narrow; and mandible is strong and wide. Supraorbital process protrudes, and traverse occipital-temporal crest is straight. Bullae are inflated.

Habitat. Forests in the southern Amazonian region.
