| Abstract | An analysis of protein variation at 26 electrophoretic loci in the blindsnake Typhlops richardi inhabiting the Puerto Rico Bank revealed the presence of three cryptic species. One, T. richardi, is restricted to the Virgin Islands; the other two occur on Puerto Rico (and satellite islands) and are sympatric. The large and widely distributed Puerto Rican species takes the available name T. platycephalus. The small Puerto Rican species, known from northern and southeastern coastal localities and some satellite islands, is described herein as T. hypomethes. Except for body size, morphological differences distinguishing all three species are slight. Typhlops richardi catapontus from Anegada is raised to species level and T. r. naugus from Virgin Gorda is placed in its synonymy. Thus, the Puerto Rico Bank and adjacent Mona Island are inhabited by seven species of Typhlops: T. catapontus, T. granti, T. hypomethes, T. monensis, T. platycephalus, T. richardi, and T. rostellatus. |
