DiagnosisDefinition. Amphisbaena kiriri sp. nov. is identified by the following combination of characters: 1) head round-shaped; 2) nasal suture >< frontal suture > prefrontal suture; 3) two precloacal pores without a median hiatus; 4) 158–165 body annuli; 5) three to four lateral annuli; 6) 12–14 caudal annuli; 7) autotomy on third or fourth caudal annulus; 8) tail tip rounded; 9) 14–16 dorsal segments on midbody annulus; 10) 15–16 ventral segments on midbody annulus; 11) four supralabials; 12) three infralabials; 13) one row of postgenials; 14) postmalar row present; 15) dorsal and ventral sulci absent, lateral sulcus present; 16) rostral, nasals, first supralabial, and (sometimes) anterior part of prefrontals cream colored; 17) dorsum dark gray; 18) first two to three ventral segments dark gray, the rest cream colored or (at least after first third of body) cream with a dark gray half-circle at anterior border.

Diagnosis. Amphisbaena kiriri sp. nov. is diagnosed from all South American amphisbaenids by the combination of two precloacal pores, 158–165 body annuli, four supralabials, and a postmalar row. The closest species in number of body annuli are A. anaemariae (156–170) and A. neglecta (151–155), which also have two precloacal pores, but three supralabials and no postmalars. The new species can be further distinguished from A. anaemariae and A. neglecta by the nasal suture longer than prefrontal suture (vs. shorter in both species) (Fig. 3 in Ribeiro et al. 2018). 
CommentMorphology: This species is one of ~20 species of Amphisbaena with two precloacal pores (Ribeiro et al. 2019). 
EtymologyThe name kiriri, used as a noun in apposition, makes reference to the indigenous tribes (also known as kariri or cariri) that once inhabited Brazilian backlands, particularly the Caatinga. Four dialects were spoken by them, all currently extinct. The word kiriri is said to have it origin in the Tupi language spoken by the natives of coastal areas, meaning ‘‘silent,’’ ‘‘taciturn’’.
