Arenaeus cribarius ( Lamarck, 1818)

(Figure 6C)

Material examined. Petro-UFS—8 (1 M, 2 F); size range: 67.30 ≤ CW ≤ 100.65 mm; average: CW = 88.99 ± 18.80 mm; CZUFS CRU- 00019. Penaeid—4 (2 M, 2 F); size range: 16.71 ≤ CW ≤ 55.43 mm; average: CW = 34.99 ± 19.99 mm; CZUFS CRU- 00244.

Stations. Petro-UFS—2, 10, 13, 14, and 16; Penaeid—4, 5, and 8.

Distribution. Western Atlantic—USA (from Massachusetts to North Carolina, Bermuda, Florida, and Gulf of Mexico), Antilles, Colombia, Venezuela, Brazil (from Ceará to Rio Grande do Sul); Uruguay, and Argentina ( Melo 1996; Scelzo 2001).

Ecological notes. Intertidal to 70 m. Well adapted to live on sandy beaches. Rarely find on estuaries or inland waters ( Melo 1996).

Remarks. Quite similar to Arenaeus mexicanus (Gerstaecker) , both species were recently redescribed and some characteristics were pointed to distinguish them as the number of rostrum teeth, spines on the carpus, and the presence or absence of a spine on the epistome. In addition, the phylogenetic analysis also suggests that these are two separate species ( Zupolini et al. 2017).
