Euplexaura amerea
Grasshoff, 1999
Euplexaura amerea
Grasshoff, 1999: 36–37
, fig. 55–58 (
New Caledonia
).
Opinion: There is no evidence that this species occurs in the region.
Justification:
These Indian records seem to be either invalid or unconfirmable
:
Kumar
et al
. 2014a: 82
, pl. 38, fig. A–D (Munak Gate);
Fernando
et al
. 2017: 75
, pl. 31, fig. A–D (Munak Gate).
Literature analysis
: The accounts of
Kumar
et al
. (2014a)
and
Fernando
et al
. (2017)
are identical but it is impossible to know the true characteristics of their specimen as a large proportion of the text is taken word-forword from Grasshoff’s paper. However, neither the colony (which has an unusual shape) nor the sclerite figures match those of the
holotype
. The sclerites of the
holotype
are described and figured as small, blunt ellipsoids, almost spherical in shape, relatively uniform in size and with small tubercles. The text of
Kumar
et al
. (2014a)
and
Fernando
et al
. (2017)
duplicates this but the figured sclerites are quite different, and they are stated to be up to twice the size. Also, the polyp sclerites bear no resemblance to those of the
holotype
, particularly the collaret sclerite at the base of the pair of point sclerites in the latter.
