Remarks
The general morphology of
Martinique
specimens corresponds well to the description in
Carpenter (1904)
, as well as that in
Müller & Krapp (2009)
, including the distal spiny tubercle on the lateral processes. However, these specimens are much smaller than other records (the trunk is about half as long as indicated in
Müller & Krapp 2009
), the ocular tubercle and lateral processes are smaller, and the number of observed cement gland pores is 13 rather than 19 as mentioned by Müller & Krapp (2019). The CO1 barcoding tree of
Sabroux
et al.
(2019b)
showed a sister-group relationship with a specimen of
Endeis mollis
from Caribbean
Colombia
identified by
Arango & Wheeler (2007)
, although the genetic distance is very high (p-distance = 0.157; see Appendix). It is therefore probably another species than
E. mollis
, but due to the complexity of taxonomy within
Endeis
, we refrain from describing it as a new species as long as a review for the genus is not available. All specimens were found at the same station, at the entrance of Baie de Fort-de-France.
Distribution
Endeis mollis
is a commonly found pantropical species recorded from the Tropical West Atlantic (Caribbean,
Surinam
,
Brazil
), West Africa (Occidental Sahara, off
Guinea
,
Nigeria
), Indian Ocean (
South Africa
,
Madagascar
,
Somalia
, Red Sea, Suez,
Oman
,
Pakistan
,
India
,
Sri Lanka
,
Maldives
, Christmas Islands,
Philippines
) and the West Pacific (
Australia
,
Japan
mainland, Ryukyu Islands,
New Caledonia
,
Guam
,
Marianas Islands
, Polynesia). There is only one record from the Western Mediterranean, north of
Tunis
.
