in his new genus. This attribution appears to have been made on biogeographic grounds, as Myers clearly indicated that he had not examined specimens of either Malagasy species. Scheel (1968) refined Myer’s definition of the genus with the addition of two additional diagnostic characters. However, the material of

actually came from the island of Nosy Be, off northwestern Madagascar. Subsequent collecting has demonstrated these two taxa differ sufficiently in coloration and morphology to warrant recognition as separate species. Parenti (1981) subsequently redefined the genus, placing particular emphasis upon several skeletal apomorphies. However, Parenti neither examined topotypical material of
