Leptogorgia thomassini
(
Tixier-Durivault, 1972
)
new comb.
Lophogorgia thomassini
Tixier-Durivault, 1972: 47
, fig. 19 (
Madagascar
).
Psudopterogorgia thomassini
(new comb.)
Williams & Vennam 2001: 88
.
Opinion: There is no evidence that this species occurs in the region.
Justification:
These Indian records seem to be either invalid or unconfirmable

Literature analysis
: Tixier-Durivault’s description of this taxon as
Lophogorgia thomassini
is very inadequate. As is often the case with that author’s works the sclerite drawings are extremely poor and do not match the text, and consequently the species is unrecognisable. William & Vennam (2001) interpreted some of the sclerite drawings as indistinct scaphoids, presumably H and I in figure 19, and transferred the species to the genus
Pseudopterogorgia
. Although these sclerites are not actually curved they are asymmetrical and have larger warts on one side, but it is the side with the greatest, and not the lessor, convexity. It is more likely the original diagnosis was correct, but the name should be
Leptogorgia thomassini
as
Lophogorgia
is a synonym of
Leptogorgia
: there are a number of species of this genus off the east coast of Africa.
The accounts of the Indian material by
Fernando (2011)
and
Fernando
et al
. (2017)
are identical and the specimen described as
Psudopterogorgia thomassini
actually appears to be a species of
Leptogorgia
as the colony form is not pinnate and there does not appear to be any scaphoids among the figured sclerites. But, unlike the
holotype
of the species, their colony does not have branches with a medial groove, the polyps are all around and not biserial, and the spindles have 2–9 whorls of warts and not 2–4. Their specimen appears to be extremely similar to, and perhaps the same as, their
Pseudopterogorgia vedalaiensi
specimen described in the same two papers.
