Comments:
Vanin (1986)
described this species from a number of specimens from Mustique Island,
Grenadines
, and from
Grenada
. According to staff at the Natural History Museum in London, all specimens (
holotype
and nine
paratypes
) from their collection were lost in return transit following description and study by Vanin. The description of the species presented here is modified from
Vanin (1986)
