First record for Brazil. Espírito Santo and Rio de Janeiro ( Christoffersen 1980)   .

Distribution. Western Atlantic: USA (Florida Keys), Caribbean Sea (e.g., Trinidad & Tobago, Curaçao) and Brazil (Ceará, Rio Grande do Norte, Paraíba, Pernambuco, Alagoas, Sergipe, Bahia, Espírito Santo, Rio de Janeiro, São Paulo) ( Christoffersen 1980; Ramos-Porto et al. 1995; Almeida et al. 2007, 2012; Riul et al. 2008; Barros-Alves et al. 2015, 2016; Pachelle et al. 2016; present study) ( Fig. 16 View FIGURE 16 ).

Ecology. On hard and mixed sand-rocky bottoms, under rocks, coral rubble, etc., depth range 1–22 m ( Chace 1972; d’Udekem d’Acoz 2000).

Remarks. Lysmata intermedia   appears to be one of the most common and widely distributed species of the genus in Brazil in the rocky intertidal. Christoffersen (1980) was the first to report the species from Brazil based on material from Espírito Santo and Rio de Janeiro. According to Christoffersen (1980) ’s detailed description of L. intermedia   , the material from Brazil agrees well with the diagnostic characters of the species, including the number of post-rostral teeth, the presence of a pterygostomial tooth, the accessory ramus of the antennule with three or four free articles and the second pereopod carpus with 25–28 subdivisions. Ramos-Porto et al. (1995) also listed the species from Pernambuco, reporting individuals with 23–26 subdivisions on the second pereopod carpus. Subsequently, a number of studies reported the species as L. cf. intermedia   , mainly due to some differences in the number of subdivisions of the second pereopod carpus between the Brazilian material and the material from southern Florida, the type locality, as redescribed by d’Udekem d’Acoz (2000) ( Almeida et al. 2007; 2012; Santos et al. 2012; Barros- Alves et al. 2015, 2016). Pachelle et al. (2016) reported L. intermedia   from Ceará, but did not mention the number of subdivisions on the second pereopod carpus of their specimens. However, a re-examination of one specimen (MZUSP 33034) listed in Pachelle et al. (2016), revealed that it has 23 subdivisions on the second pereopod carpus on both sides. Thus, at least some specimens from Pernambuco and Ceará seem to have fewer subdivisions (23–26) in the second pereopod carpus than the topotypical specimens from Florida (25–31, typically 28–30, d’Udekem d’Acoz 2000) and Christoffersen’s (1980) specimens from Espírito Santo and Rio de Janeiro (25–28) (see also Table 1 and discussion of the diagnostic characters of Lysmata   below).

A specimen from Rio Grande do Norte (MZUSP 29792) presented a stout spiniform seta on the first pereopod merus, on the ride side ( Fig. 7E View FIGURE 7 ); however, because this spiniform seta was present only on the right appendage, it seems to be an atypical condition.

The colour pattern of the Brazilian and Caribbean specimens appears to be nearly identical (cf. Rhyne et al. 2012: fig. 5; Barros-Alves et al. 2015: fig. 1D, 2016: fig. 1b; Pachelle et al. 2016: fig. 9).

Terossi et al. (2018) re-examined one specimen of Barros-Alves et al. (2016) ’s material of L. intermedia   from Ubatuba, São Paulo (MZUSP 32642) and reassigned it to L. jundalini   . According to these authors, the specimen from Ubatuba matches L. jundalini   because the lateral antennular flagellum has 23 articles in the fused portion, before its bifurcation with the accessory ramus (versus 9–17 in L. intermedia   , according to d’Udekem d’Acoz 2000). We re-examined this specimen and confirmed that the right lateral flagellum has indeed 23 subdivisions in the fused portion; however, some of these subdivisions are somewhat swollen, suggesting an abnormal development ( Fig. 6 View FIGURE 6 , white arrow; also note the difference in length between the left (normal) and right (abnormal) accessory ramus of the lateral antennular flagella). Unfortunately, the left lateral flagellum is broken near the base in the preserved specimen. Terossi et al. (2018) did not comment on the number of subdivisions in the second pereopod carpus of the Ubatuba specimen (23 according to Barros-Alves et al. 2016), but our study revealed that the specimen actually has 25 subdivisions on the right side and 27 on the left side, which is within the range of L. intermedia   . The colour photographs of the material reported by Barros-Alves et al. (2016) show neither a blue spot near the fourth pereopod coxa ( Fig. 6 View FIGURE 6 , black arrow) nor bright orange chromatophores on the dorsal surface of the third to fifth pereopods, which are diagnostic colour features of L. jundalini   ( Rhyne et al., 2012; see also Fig. 10 View FIGURE 10 ). Based on these observations, the specimen from Ubatuba (MZUSP 32642) is here re-identified as L. intermedia   . However, the possible occurrence of L. jundalini   in Brazil is discussed below.

Manning & Chace (1990) listed Rio Grande do Norte in the distribution range of L. intermedia   , however, without providing more details or listing material or references. Christoffersen (1998) stated that “the presence of the species in Rio Grande do Norte has not been confirmed”. Thus, our material from Praia de Baixa Grande represents the first confirmed record of L. intermedia   in Rio Grande do Norte   .
