Type locality: Boca del Toro, Granma Province, Cuba.

TypesHolotype: MNHNCU 4421. Paratypes: MNHNCU 4422, USNM 512213, 512214, UMMZ 90720. 
DiagnosisDIAGNOSIS: Three Cuban species, Amphisbaena cubana, A. barbouri, and A. carlgansi, share a major fusion of head scales (ocular + second supralabial) not found in other Antillean species of the genus (Gans and Alexander, 1962). Therefore it is appropriate to compare A. carlgansi with A. cubana and A. barbouri. Of the three species, A. carlgansi is most similar to A. barbouri and thus the diagnostic differences distinguishing A. barbouri from A. cubana also distinguish A. carlgansi from A. cubana. Most notably, A. barbouri and A. carlgansi are smaller and more slender species with higher numbers of body and caudal annuli and lower interfrontal/interprefrontal and intemasal/ interprefrontal ratios (Table 1). The most relevant comparison of A. carlgansi is with its presumed closest relative A. barbouri. The two species can be separated by a combination of the following characters: tail length/ SVL (0.080-0.086 in carlgansi, 0.060-0.079 in barbouri) (Fig. 3), coloration (pale pinkish-tan in carlgansi, medium brown in barbouri), number of body annuli (212-228 [x̅ = 219] in carlgansi, 226-240 [x̅ = 233] in barbouri), and total midbody segments (31-34 [mode = 32] in carlgansi, 28-32 [mode = 30, 31] in barbouri) (Table 1). (Thomas & Hedges 1998).
