03AD87B2FFB15D0A35C9FE4CFD38FB43.taxon	discussion	Remarks. In the sampling conducted during the REVIZEE Program Central Score, B. biunguiculatus was found at stations with depths ranging from 50 to 100 m (C 5 - 2 R, C 5 - 13 R, and C 5 - 16 R) and at stations C 5 - 4 F and C 5 - 7 F, to which were attributed much greater depths of 1700 to 1500 m, respectively (Serejo et al. 2006). As the latter depths are far beyond the usual depth limit of this species, it is likely that either collection station or depth attributions in Serejo et al. (2006) were erroneous.	en	Almeida, Alexandre O., Boehs, Guisla, Araújo-Silva, Catarina L., Bezerra, Luis Ernesto A.

03AD87B2FFB35D0935C9F964FD9DFBC2.taxon	discussion	Remarks. Alpheus armillatus is a large species complex with six nominal species in the eastern Pacific and four nominal species in the western Atlantic, two of them currently seen as synonyms of A. armillatus (Anker 2001; Mathews, 2006; Mathews & Anker 2009). However, molecular data suggest the existence of at least 19 distinct ESUs within this complex, including 11 in the western Atlantic (Mathews & Anker 2009). The western Atlantic species of the A. armillatus complex are currently being revised (A. Anker, pers. com.). Alpheus cf. armillatus was the most abundant alpheid in our samples. Two distinct color patterns of A. cf. armillatus indicate existence of at least two species in Bahia.	en	Almeida, Alexandre O., Boehs, Guisla, Araújo-Silva, Catarina L., Bezerra, Luis Ernesto A.

03AD87B2FFB25D0935C9FB4DFD9AF818.taxon	discussion	Remarks. In the western Atlantic, A. bouvieri can be easily confused with the amphi-Atlantic A. agilis Anker, Hurt & Knowlton, 2009. However, A. bouvieri can be separated from A. agilis by the absence of spiniform setae on the P 3 and P 4 ischium, as well as the much more distinct rostral carina (Anker et al. 2009 a). Based on these characters, the material from southern Bahia was identified as A. bouvieri. The color pattern of A. bouvieri consists of transverse brownish bands on the carapace and abdomen and includes a characteristic whitish spot on the mesial surface of the major chela palm (Fig. 2 A).	en	Almeida, Alexandre O., Boehs, Guisla, Araújo-Silva, Catarina L., Bezerra, Luis Ernesto A.

03AD87B2FFBF5D0435C9FE1EFAB3FBE0.taxon	discussion	Remarks. Many previous records of A. heterochaelis from Brazil were based on misidentifications and confusion with A. armillatus, A. bouvieri and A. nuttingi (Schmitt, 1924), among others (Christoffersen 1984). However, according to this author, A. heterochaelis s. str. does occur in Brazil, for example, in Pará and Paraíba states. Almeida et al. (2006) extended the southern distribution of A. heterochaelis to Ilhéus, Bahia. Alpheus pontederiae de Rochebrune, 1883, which also occurs in Brazil (see below), differs from A. heterochaelis by the presence of two small prominences on the mesial side of the major chela pollex, and by the distolateral spiniform seta of the uropodal exopod being flanked by two small, acute teeth. The record of A. heterochaelis from the Abrolhos Bank (Young & Serejo 2005) is extremely doubtful, since this species is typically found in estuarine habitats.	en	Almeida, Alexandre O., Boehs, Guisla, Araújo-Silva, Catarina L., Bezerra, Luis Ernesto A.

03AD87B2FFBF5D0535C9F977FD3DFD7A.taxon	discussion	Remarks. Kingsley (1878) described A. normanni based on specimens from the Pacific coast of Panama. Two years later the same author described A. packardii based on specimens from Key West, Florida (Kingsley 1880). Chace (1937) compared the eastern Pacific and the western Atlantic (Bermuda) materials of A. normanni and A. packardii and concluded that they are identical morphologically, placing A. packardii in the synonymy of A. normanni. Both Chace (1972) and Christoffersen (1979) continued to treat A. packardii as a junior synonym of A. normanni. Kim & Abele (1988) again compared specimens from the eastern Pacific and western Atlantic (Florida). These authors found consistent morphological differences between the eastern Pacific and western Atlantic specimens, viz. in the fingers of the minor chela, and removed A. packardii from the synonymy of A. normanni. However, the taxonomy of both A. normanni and A. packardii remains unsettled due to the presence of several cryptic taxa in the eastern Pacific and western Atlantic (A. Anker, in study). Thus, it is presently impossible to determine the true identity of the Bahian material.	en	Almeida, Alexandre O., Boehs, Guisla, Araújo-Silva, Catarina L., Bezerra, Luis Ernesto A.

03AD87B2FFB95D0235C9FE8EFCB0FAE4.taxon	discussion	Remarks. This species is morphologically close to A. cf. paracrinitus but differs from it in the color pattern. Alpheus cf. rostratus has wide transverse bands on the carapace and abdomen and a pair of dark dorsal spots on the third abdominal somite (see Figs. 2 D and 2 E for comparison). A similar color pattern exists in the eastern Pacific A. rostratus, which belongs to the A. paracrinitus complex (A. Anker, pers. comm.). Some minor morphological differences were noted between A. cf. rostratus and A. rostratus, based on the original description and figures (Kim & Abele 1988). For example, A. cf. rostratus differs from A. rostratus by the more strongly produced distodorsal margin of the antepenultimate article of the third maxilliped. In A. cf. rostratus, the distolateral tooth of the scaphocerite extends slightly beyond the anterior margin of the blade, and the cleft between the blade and the tooth is approximately 1 / 3 of the total length of the scaphocerite. In cotrast, in A. rostratus, the distolateral tooth of the scaphocerite extends conspicuously beyond the anterior margin of the blade, and the cleft between the blade and the tooth slightly less than 1 / 2 of the total length of the scaphocerite. In A. rostratus, the tooth on the ventromesial carina of the antennular peduncle is concave, whereas in A. cf. rostratus, the anterior margin of this tooth is nearly straight. These differences, if shown to be valid and consistent, suggest that the Bahian material may belong to a new species close to A. rostratus. However, only a taxonomic revision of the entire A. paracrinitus complex will clarify the identity of A. cf. rostratus and A. cf. paracrinitus. Therefore, all records of A. paracrinitus from Brazil (Christoffersen 1998) need to be treated with a lot of caution.	en	Almeida, Alexandre O., Boehs, Guisla, Araújo-Silva, Catarina L., Bezerra, Luis Ernesto A.

This first record of L. axianassae from Bahia fills a significant gap in the species distribution in Brazil, which extends from Pernambuco to São Paulo. The species is easily recognizable by the short antennular peduncles (with articles slightly longer than wide) (Fig. 4 A) and the presence of only one large, triangular, obtuse tooth on the cutting edge of the major chela pollex (Fig. 4 C, D; see also Dworschak & Coelho 1999, p. 480, fig. 18). Another important feature of L. axianassae, viz. the presence of a small tubercle on the eyestalks, was not observed to avoid damage of the rare material.	en	Almeida, Alexandre O., Boehs, Guisla, Araújo-Silva, Catarina L., Bezerra, Luis Ernesto A.

The scaphocerite of the Bahian specimen of S. ul has a distinct blade (Fig. 7 G) similar to that of S. pandionis. However, it differs from S. pandionis in having unequal spiniform setae on the posterior margin of the telson, with the lateral pair being shorter than the mesial pair (Fig. 6 D); these setae are subequal in length in S. pandionis. In S. ul, the distolateral tooth of the uropodal exopod is adjacent to the preceding spiniform seta (Figs. 6 E, F) (vs. more separated and with a small lobe between them in S. pandionis); and the mesial protuberance (erroneously referred as lateral side in Ríos & Duffy 2007) on the base of the major chela pollex, characteristic of S. pandionis, is absent (Fig. 7 F). Synalpheus ul also resembles S. hoetjesi Hultgren, Macdonald & Duffy, 2010, but differs from it by the presence of a scaphocerite blade (20 – 75 % the length of scaphocerite vs. absent or vestigial in S. hoetjesi) (Fig. 7 G), the shape of the distal superior margin on the major chela (gently sloping in S. ul vs. bulging over the accessory tooth in S. hoetjesi) (Figs. 7 A, B), and the thickness of the spiniform setae on the posterior margin of the telson (mesial subequal to lateral in S. ul vs. mesial larger than lateral in S. hoetjesi). The present record of S. ul from Bahia, the first for Brazil and the southwestern Atlantic Ocean, significantly extends the southern range of this species.	en	Almeida, Alexandre O., Boehs, Guisla, Araújo-Silva, Catarina L., Bezerra, Luis Ernesto A.

(2007 b) reported some differences between L. cf. intermedia from Camamu Bay, Bahia, and topotypical specimens of L. intermedia (d’Udekem d’Acoz 2000). The main difference observed (here confirmed by the analysis of two additional individuals) was in the number of articles in the P 2 carpus (23 – 25, more commonly 23 in L. cf. intermedia vs. 25 – 31, more commonly 28 – 30 in L. intermedia). Other small differences were observed in the number of articles in the P 2 merus and in the spinulation of the P 3 – P 5 merus and propodus, suggesting that this material belongs to a hitherto undescribed species.	en	Almeida, Alexandre O., Boehs, Guisla, Araújo-Silva, Catarina L., Bezerra, Luis Ernesto A.
