THE FRESHWATER SNAIL GENUS SULCOSPIRA TROSCHEL, 1857 FROM JAVA, WITH DESCRIPTION OF A NEW SPECIES FROM TASIKMALAYA, WEST JAVA, INDONESIA (MOLLUSCA: GASTROPODA: PACHYCHILIDAE)

Members of the viviparous freshwater snail genus Sulcospira Troschel, 1858 occur in lotic habitats in Southeast Asia. Three species have been reported from Java, two of which (Sulcospira sulcospira and S. pisum) may have become extinct, while S. testudinaria is fairly common. Based on recent collections, here we describe a new species, Sulcospira kawaluensis, from Tasikmalaya, West Java. Shell, embryonic shell, and radula characters of the new species clearly differ from those in S. testudinaria. Sulcospira kawaluensis new species has a rather restricted occurrence near Tasikmalaya in West Java.
