Isis hippuris
Linnaeus, 1758
Isis hippuris
Linnaeus, 1758: 799
(unknown locality);
Bayer & Stefani 1987: 55–57
, pl. 1–7.
Opinion: It is not possible to determine if this species occurs in the region.
Justification:
These Indian records seem to be either invalid or unconfirmable

Literature analysis
:
Bayer & Stefani (1987)
detailed many morphologically different forms of putative
Isis hippuris
specimens from the
Philippines
and the Ryukyus across to
New Caledonia
that showed a huge range of sclerite forms, and Rowley
et al
. (2015) suggested there may have been two different species at her study sites in
Indonesia
. The first record of the species occurring in the region is that of
Simpson (1906)
, but his material contained quite different sclerites in the tentacles and its identity was questioned by Bayer & Stephani. Unfortunately, none of the other descriptions of Indian specimens assigned to this species mention the tentacle sclerites, and the surface sclerites the authors illustrate are different from those shown by Simpson and also by Bayer & Stephani (1987).
Kumar
et al.
(2019b)
lists the species and present a very small underwater image of a colony that seems to be similar to those from the Indo-Pacific generally assigned to this species, but the colonies figured by Simpson,
Thomson & Simpson (1909)
,
Kumar
et al
. (2014a)
and
Fernando
et al.
(2017)
have a different and quite an unusual growth form. The descriptive texts given by
Fernando (2011)
and
Fernando
et al.
(2017)
are identical, but the illustrations are different, there being only naked colony axes in the 2011 paper. The illustrations in the 2017 paper are the same as those in
Kumar
et al
. (2014a)
.
Thomas & George (1987)
and
Rao & Devi (2003)
just list the species, and
Kumar
et al
. (2015
,
2018
) list the species and provide an image of part of the material from 2014 and 2017 papers mentioned above.
Kumar
et al
. (2019b)
lists the species and provide a colony image, while
Kumar
et al
. (2018a)
just lists the species.
