Genus Indoartemon Forcart, 1946

Odontartemon (Odontartemon) : Kobelt, 1905: 91 (non Pfeiffer, 1856). Thiele, 1931: 730.

Oophana (Indoartemon) Forcart, 1946: 215 . Benthem Jutting, 1954: 95.

Indoartemon: Zilch, 1960: 562 . Richardson, 1988: 223–225. Schileyko, 2000: 776, 777.

Type species. Streptaxis eburnea Pfeiffer, 1861 , by original designation.

Remark. Shells of Oophana and Indoartemon are similar but there are differences in the apertural dentition. Indoartemon possesses one parietal lamella and one palatal lamella; in addition basal and columellar lamellae are present in I. layardianus ( Benson, 1853) and I. cingalensis ( Benson, 1853) . Apertural dentition of Oophana usually includes a single parietal lamella, palatal lamella, basal lamella, and columellar lamella. An upper palatal lamella or supracolumellar lamella are present in some species such as Oophana strangulatus ( Möllendorff, 1894) , O. diplodon ( Möllendorff, 1900) , and O. pachyglottis ( Möllendorff, 1900) .

The first genital morphological study of Indoartemon presented here indicates that the following characters may be diagnostic for the genus; a long penis with a thin penial sheath extending about half of the penis length; penial hooks present. The vas deferens does not pass through the penial sheath. The seminal vesicle is about one and a half times longer than the length from the talon to the branching point of the seminal vesicle. In Oophana the vas deferens enters the penial sheath distally, penial hooks and a seminal vesicle are present ( Berry, 1963).
