As Tethorchestia sp. B, Bousfield 1984, p 204; ‘Tethorchestia’ LeCroy 2011, p 757; Mexorchestia carpenteri carpenteri Wildish and LeCroy 2014, p. 562 .

Material examined

Two samples, 5B and 9A, n = 14, both from Stovell ’ s Bay on Spanish Point. This taxon was found in the same bleached Enteromorpha wrack with P. monodi BOLD: AAB 3402.

Distribution

This taxon was found in only one location, Stovell ’ s Bay, of the 19 locations sampled.

Remarks

Live specimens can readily be distinguished by the conspicuous red and black epidermal pigment patterns present on a pale white or fawn-coloured background ( Figure 3 ). In the Florida specimens of this taxon ( Wildish and LeCroy 2014) the pigment patterns are also variable. It is of interest that the bauplan of the Bermuda dorsal pigment patterns are very similar to those recorded by Wildish and Lecroy (2014, see fig. 6D); for coastal Atlantic specimens of this taxon at Fort Lauderdale, Florida.
