Based on our results, we recognize each of the three currently described taxa as separate species, and describe two additional species. Vermicella multifasciata is restricted to those specimens from the Darwin area that display exceptionally high numbers of and very thin body bands, and is sympatric with a new species described in this paper. Vermicella snelli is restricted to northern Western Australia and a second species from the Alice Springs area of the Northern Territory that displays fewer body bands is described. Males have a lower mean number of ventral scales and a higher mean number of subcaudal scales than females in the four species with sample sizes large enough for meaningful statistical analyses, and V . In conjunction with the taxonomic study, we also examined reproductive biology and diet of Vermicella .
Females reach larger adult body sizes than males in V .
Gut contents of four species confirm previous studies suggesting that they feed solely on blind snakes of the genus Ramphotyphlops . Clutch sizes for the smaller species of Vermicella are low, ranging from one to four, while published data for the larger V . Back to Publication list. Allometry and sexual dimorphism in the lung morphology of prairie rattlesnakes, Crotalus viridis viridis . We quantified sexual dimorphism and allometric changes in the lung morphology of 160 juvenile and adult specimens of prairie rattlesnake, Crotalus viridis viridis , from a single population.
