First record of Amphidromus from Australia, with anatomical notes on several species (Mollusca: Pulmonata: Camaenidae)
Abstract
Amphidromus cognatus Fulton, 1907, described from a single specimen without locality data, is here recorded from several places north of Darwin in the Northern Territory. This is the first record from Australia of this South-east Asian to Timor genus of arboreal snails. Dissections of the genotype, Amphidromus perversus (Linné, 1758) from Bali and A. poecilochrous jaeckeli Laidlaw, 1954, from Flores, Indonesia, provide comparative data on genital and radular structures of A. cognatus. There are easily observable species differences in the terminal genitalia, although shell variation is great and confusing.
