Remarks

This species was reported for the first time in Martinique (Petite Anse Macabou) by Müller (1990a) as Tanystylum sp. , and was formally described later by Müller & Krapp (2009) from Colombia. The characteristic tubercle near the abdomen base is quite variable in size, but it is generally lower in the studied material compared to Müller & Krapp’s drawing. This tubercle is the only conspicuous character differentiating T. tayronae from T. geminum Stock, 1954 . A more diversified sampling of this species and DNA barcodes are needed to make sure the two species are not synonymous.

All specimens were collected on the Atlantic and Caribbean coasts of Martinique.

Distribution

So far only known from the Caribbean ( Colombia and Martinique).

Depth range

0–2 m, extended to 15 m.
