Remarks. This is the second record of a species recently described from Guadeloupe by Galea (2010), extending its known range northwards to Florida from the Caribbean Sea. Male gonothecae are illustrated for the first time ( Fig. 6c View FIGURE 6 ). They differ from those of the female ( Fig. 6b View FIGURE 6 ) in having fewer lateral crests and in being approximately 30% smaller.

Morphologically, Halecium calderi Galea, 2010 closely resembles Halecium sibogae Billard, 1929 (type locality: Indonesia) and H. sibogae marocanum Billard, 1934 (type locality: Morocco). Relationships of these nominal species-group taxa remain unresolved. For now, the binomen established by Galea (2010) for the warm western North Atlantic population is adopted.

Reported distribution. Atlantic coast of Florida. First record.

Western Atlantic. Florida (this record) to Guadeloupe ( Galea 2010).
