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
).
