A new species of Amphisbaena is described from municipalities of Babaçulândia, State of Tocantins, and Estreito, State of Maranhão, northern Brazilian Cerrado. The new species differs from other two-pored species of the genus, by presenting mainly slender body shape; snout rounded in profile and dorsal view; high number of body annuli (328-342); 12-14 dorsal segments and 14-16 ventral in midbody half-annulus; autotomic site between 9-10 caudal annuli; absence of chevron-shaped anterior dorsal half-annuli; 20-23 caudal annuli; postmalar row absent; and precloacals pores arranged in a continuous series of the precloacal half-annuli. Additionally, we present a key for two-pored species of Amphisbaena.

A new species of Garra (Labeoninae) is described from the Zubza River, a headwater of the Brahmaputra River basin, in Kohima district of Nagaland, North-eastern India. The new species is distinguished by the following combination of characters: a black spot located on the principal ray and first three branched rays of the dorsal (upper) lobe distal part, as well as a black submarginal V-shaped band on the principal ray and whole branched rays of the ventral (lower) lobe of caudal fin; snout with weakly-developed proboscis represented by slightly upwards elevated hump, with no transverse groove and no transverse lobe, and with 10-12 small tubercles on anterodorsal marginal aspect; 34 lateral-line scales including two pored scales on caudal fin; absence of scales on chest and presence of poorly developed scales on belly; relatively shorter caudal peduncle (10.7-12.

Here, we describe a new species of Amphisbaena with two precloacal pores from open Cerrado areas of the municipality of Arenópolis, in the Brazilian state of Goiás. The new species differs from other South American amphisbaenids by the folllowing combination of characters: (1) snout rounded in dorsal view and slightly convex in lateral view; (2) two precloacal pores; (3) 161-176 dorsal half-annuli; and (4) 12-15 tail annuli. Our molecular phylogenetic analysis retrieved a monophyletic Amphisbaena silvestrii group, with A.
