Abstract

The land snail Leptopoma (Leucoptychia) lamellatum Sykes, 1903 wasreported from the Raja Ampat Islands, West Papua. The type locality of this snail isWaigeo Island, but it also occurs on Salawati island. Based on specimens collected in2007 and 2008 from Waigeo, Salawati and Batanta, we present a re-description of theshell including new information on body coloration, radular morphology and habitat.The known range of the species is extended to include Batanta Island.

Abstract

The freshwater gastropod Tarebia H. Adams & A. Adams, 1854, are found in rivers, lakes, and other limnetic habitats. In Indonesia, Tarebia granifera (Lamarck, 1822) is the only species within the genus that has a wide distribution. The systematics and identity of this species are still doubtful due to high variation in shell morphology, especially shell height and ornamentation or sculpture of shell. To determine the identity of T. granifera from Lombok, Banten, and Maros, ontogenetic studies have been conducted. The results showed that T. granifera from Lombok produce the highest number of embryonic shells. The number of progeny in the brood pouch from a single individual of T. granifera can vary between 9 to 203 embryonic shells which are found in various stages of 0.22 mm to about 5 mm in size inside the brood pouch.
