“…In Brazil, few studies have been conducted on crustacean setae, for instance in the study of adult Anomura MacLeay, 1838 and Parastacidae Huxley, 1879 (Horn & Buckup, 2004); in larval stages of shrimp (Calazans & Ingle, 1998) and crabs (Rieger & Santos, 2001;Rieger et al, 2003), and the oral appendages of Thalassinidea Latreille, 1871 (Coelho et al, 2000), with functional importance in the capture, selection and manipulation of food.…”

Thejuveniledevelopment of the freshwater crab Dilocarcinus pagei Sdmpson, 1861 was studied under laboratory conditions, focusing on setae morphology. The ovigerous females were eollected manually associated with water hyacinth at the Municipal Dam of Sao José do Rio Preto (Sao Paulo, Brazil). The specimens were raised in the laboratory under constant aeration, photoperiod (12:12 h) and temperature (27 ± 1°C). Twelve juvenile stages were obtained with descriptions of the main morphological characters that allow their identification are presented. Fourteen types of setae were discovered: dentate, denticulate, serrulate, papposerrate, cuspidate, plumose, plumodenticulate, plumoserrulate, simple, pappose, brush, curved, nail and setules. The greatest diversity of setae was found on the mouth appendages, especially the maxillule. The gill ontogeny and sexual dimorphism becomes apparent from the second juvenile stage onwards. At the third juvenile stage, the carapace begins to exhibit a wider shape, becoming similar to that of the adults.

“…However, the dorsal rows of scales accompanying the denticules on the serrate setae of thalassinideans is similar to those of porcellanids, but distinguished from the dense digitiform setules lying above the denticules on the brush setae of lithodids. Moreover, setae similar to the P5 serrate setae of the present species have been noted on the anterior limbs of other callianassids (Stamhuis, Dauwe & Videler, 1998) and upogebiids (Coelho, Williams & Rodrigues, 2000) where they were associated with feeding.…”

“…This difference in setal complement of the P5 brushes between the two species is perhaps conservative at the family level (cf . Nickell et al, 1998;Stamhuis et al, 1998;Coelho et al, 2000). Although gill-cleaning methods (active type) are similar in N. japonica and U. major, the setal composition and extent of their P5 brushes are morphologically differentiated.…”

The burrowing habits of thalassinidean shrimps presuppose their high susceptibility to the deleterious effects of gill fouling by particulate debris and epibionts. The structures and strategies used to prevent gill fouling were examined in Nihonotrypaea japonica and Upogebia major by morphological inference and aquarium observations. The gill complement of both species consists of 10 arthrobranchs, with flattened filaments of the phylloid trichobranch type. Nihonotrypaea japonica and U. major lack passive gill-cleaning setal systems in the branchial chamber, but were found to actively groom gills by inserting and brushing the gill filaments with a pad of dense setae on the distal segments of their fifth pereiopods (P5 brush). Grooming setae of the P5 brush in N. japonica are of serrate and plumose types, whereas they are serrate and pappose in U. major. Serrate setae with distally curved spiniform denticules were morphologically similar in both species. Phylogenetic mapping of the gill-cleaning mechanisms suggests that gill-cleaning characters are homoplasic and systematically conservative among the families of the Thalassinidea.

“…All the setae were identified with a letter that indicates their category (A-G), and a number that indicates the number of variations found (FACTOR 1978, COELHO & RODRIGUES 2001a. The pores were named according to their specific morphology.…”

ABSTRACT. This study describes the morphology and arrangement of the cuticular structures of Hyalella castroi González, Bond-Buckup &Araujo, 2006 and Hyalella pleoacuta González, Bond-Buckup &Araujo, 2006, to identify specific characters that can be used in taxonomstudies of this genus. The entire cuticular surface of both species was examined by optical and scanning electron microscopy. The data obtained were compared with available information for other members of Peracarida, mainly Amphipoda and Isopoda. Five different types of cuticular structures, including 30 types of setae, four types of microtrichs, three types of pores, and some structures formed by setules and denticles were identified. The results were compared with other groups of gammarids, and peracarideans, such as Thermosbaenacea and Isopoda. The use of cuticular structures as a tool for taxonomic studies showed important results, not only at species level, but also at genus, and family levels.
