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).
