Cyclophorusis one of the genera in terrestrial gastropods that inhabits forest floor, leaf litter, rocks, and decayed wood.This research aims to determine the morphological and anatomical characters of the genus Cyclophorusin Indonesia and its phenetic relationship. Descriptive method was applied by conducting observation onshell, operculum, as well as anatomical characters. Cluster analysis in Rstudio was conducted to analyze the morphological data and to see its phenetics relationship. Based on 214 shell and 21 genitalia, 12 Cyclophorusspeciesand subspeciesstored in the Museum Zoologicum Bogoriense (from the total of 20speciesand subspeciesin Indonesia) were identified. The morphological character of the Cyclophorusin Indonesia (shell and operculum) can be differentiated based on the shell shape, shell pattern, spiral bands, the number of whorls, shell diameter, and operculum. Diagnostic characters in the genitalia are the bursa copulatrix and oviduct (female), and penis (male). The cluster analysis shows the separation of adult shells and operculum into six (6) groups i.e. (1) C. nigricansfrom Sulawesi is allegedly a distinctive species of the eastern region in Indonesia; (2)C. rafflesiieximiusfrom Sumatra and Java; (3) C. theobaldianusfrom Kalimantan; (4) C. rafflesiidan C. rafflesiirafflesiifrom Sumatra and Java; (5) C. schepmaniand C. stevenabbasorumfrom Sumatra which an allegedly the typical species of Sumatra; and (6)C. tuba plicifera, C. tuba, C. perdix, C. perdix perdix and C. perdix borneensisfrom Sumatra, Java and Kalimantan.
