Macrocoeloma laevigatum ( Stimpson, 1860)

(Figure 5F)

Material examined. Petro-UFS—4 (1 M); CW: 11.48 mm; CZUFS CRU- 00105. Penaeid—1 M; CW: 2.3 mm; CZUFS CRU- 00319.

Station. Petro-UFS—4, 5, and 18; Penaeid—3.

Distribution. Western Atlantic—Florida ( USA), West Indies to Brazil (from Pará to Sergipe) ( Barreto et al. 1993; Melo 1996; Serejo et al. 2006; Almeida et al. 2007 a; Barros-Alves et al. 2015).

Ecological notes. From shallow waters to a depth of 30 m. On sandy and rocky substrates and algae bottoms ( Melo 1996).

Remarks. According to the classification of Ng et al. (2008) this species belonged to the subfamily Mithracinae , which was raised recently to family Mithracidae ( Windsor & Felder 2014) . However, some genera, including Macrocoeloma Miers , were removed from Mithracidae based on molecular phylogenetics (12S, 16S and COI mitochondrial genes) and a morphological re-examination. This genus is now considered an incertae sedis group, closely related to other Epialtidae ( Windsor & Felder 2014) . As the position of M. laevigatum is not well defined, we decided to follow the classification of Ng et al. (2008) and retained it in the family Majidae .
