Abstract

The Neotropical blindsnakes of the genus Anomalepis are reviewed. Four species are recognized: A. mexicanus in Costa Rica, Panama and Peru; A. colombia in Colombia; A. flavapices in Ecuador; and A. aspinosus in Peru. Numbers of dorsal scales and scale rows around the body are the only characteristics by which the species can be diagnosed. Anomalepis colombia, A. flavapices and A. aspinosus comprise a species group (the aspinosus group) with a combined geographic distribution somewhat similar to that of A. mexicanus, but more restricted. The aspinosus group is characterized by higher numbers of dorsal scales and scale rows: 308-363 dorsals, and a scale-row formula of (26-27-28-30)-(24-26-30)-(24-27). Anomalepis mexicanus is characterized by fewer numbers of dorsal scales and scale rows: 259-299 dorsals, and a scale-row formula of (24-25-26)-(20-22-23-24)-(20-21-22). Anomalepis flavapices and A. aspinosus may be synonymous.
