A second species of Brasilotyphlus (Amphibia: Gymnophiona: Caeciliidae) from Brazilian Amazonia

摘要

Brasilotyphlus is rediagnosed in light of the discovery of a second species of the genus, B. guarantanus sp. nov., in the municipality of Guaranta do Norte, state of Mato Grosso, Brazil. The new species differs from B. braziliensis mainly in annular counts, having 151-170 primaries and at most 2 secondaries (instead of 142-147 primaries and 23-36 secondaries).
