Brasilotyphlus
''Brasilotyphlus'' is a genus of caecilians in the Siphonopidae family. It was considered monotypic, containing only the species ''Brasilotyphlus braziliensis'', but the recently described species ''Brasilotyphlus guarantanus'' has been placed in this same genus. Both species have only been recorded from Brazilian Amazonia.〔Maciel, A.O. & M.S. Hoogmoed, "Taxonomy and distribution of caecilian amphibians (Gymnophiona) of Brazilian Amazonia, with a key to their identification" Zootaxa, 2984: 1-53〕 This genus has also been suggested as paraphyletic to ''Microcaecilia''.〔
==History==
The genus was discovered less than a century ago, and relatively little is known about it to date.〔The physical shape and structure of ''Brasilotyphlus'' has been recorded, while information concerning even basic biology, such as physiology and habitat, of this genus is lacking. Currently, it is known to be a subterranean genus living in the rainforest of Brazil.〔Miguel Trefaut Rodrigues, Claudia Azevedo-Ramos, Mark Wilkinson, ("Brasilotyphlus braziliensis" ) IUCN Red List of Threatened Species Version 2012.2〕 Further, the threats to this genus are currently unknown, as its ability to adapt to a secondary habitat has not been observed.〔 Both species have been located exclusively in Brazil. Their known locations are small and restricted. They were found independent of each other, and their habitats may not overlap. The closest known habitats for the two species, with respect to each other, are approximately 950 km apart.〔Adriano O. Maciel, Tami Mott, Marinus S. Hoogmoed, "A Second species of Brasilotyphlus (Amphibia:Gymnophiona:Caeciliidae) from Brazilian Amazonia" Zootaxa 2009〕 Beyond this there is little to no knowledge as to the distribution of this genus, which makes locating a subject for research quite difficult.〔Cardoso Pinheiro, Leandra, Youszef Oliveira Da Cunha Bitar, Ulisses Galatti, Selvino Neckel-Oliveira, and Maria Cristina Dos Santos-Costa ("Amphibians from Southeastern State of Pará: Carajás Region, Northern Brazil" ) Check List 8.4 (2012): 693-702〕 The first of these species, ''Brasilotyphlus braziliensis'' has not even been seen since 1997.〔 Even the classification of this genus is a source of confusion, as not all scholars agree on the phylogeny.〔Unknown, ("Brasilotyphlus Braziliensis." ), AmphibiaWeb – Inaturalist,〕 To date, no photographs have been published of the living ''Brasilotyphlus brasiliensis''.〔
