First record for Brazil. Ceará (Fausto Filho 1970, as H. (H.) wurdemanni , see under Remarks below).

Distribution. Western Atlantic: Panama and Brazil (Ceará, Sergipe, Bahia, Rio de Janeiro, São Paulo) ( Rhyne & Lin 2006; Barros-Alves et al. 2015; Pachelle et al. 2016) ( Fig. 16 View FIGURE 16 ).

Ecology. Typically on hard and mixed bottoms, such as rocky reefs and shallow fossilised reef terraces with abundance of small caves and other shelters, depth range: 1–25 m ( Rhyne & Lin 2006; Barros-Alves et al. 2015).

Remarks. Lysmata bahia is one of the three species of the L. wurdemanni complex presently known to occur in Brazil. It can be separated from L. ankeri and L. wurdemanni by the longer stylocerite, reaching or almost reaching the distal margin of the first article of the antennular peduncle (versus reaching to about mid-length of this article in L. ankeri and L. wurdemanni ) ( Fig. 4A View FIGURE 4 ; see also Rhyne & Lin 2006: figs. 1A–B, 7A–B, 16A–B). In life, L. bahia can be easily distinguished from L. ankeri by the presence of a transverse band on the posterior margin of the second pleonite and the more heterogeneous pattern of the dorsal stripes on the second and third pleonites ( Figs. 1 View FIGURE 1 , 3 View FIGURE 3 ; see also Rhyne & Lin 2006: pl. 1). Although L. bahia and L. wurdemanni share a similar arrangement of bands and stripes on the pleon, L. bahia can be separated by the less intense transverse band on the posterior margin of the third abdominal somite ( Fig. 3 View FIGURE 3 ; Rhyne & Lin 2006: pl. 1; Terossi et al. 2018: fig. 2C–D). Additionally, L. bahia differs from L. ankeri by the colour of freshly laid eggs, which are green in L. bahia and pink in L. ankeri . Lysmata bahia also has been shown to be genetically separated from L. ankeri and L. wurdemanni ( Baeza et al. 2009; Baeza 2010, 2013).

Fausto Filho (1970) was the first author to report specimens of L. bahia from Brazil, under the name Hippolysmata wurdemanni ( Pachelle et al. 2016) . Chace (1972) mentioned specimens of L. wurdemanni from Santos, São Paulo, which were later designated as paratypes of L. bahia by Rhyne & Lin (2006). The distribution map for L. bahia in Rhyne & Lin (2006 : pl. 2) includes Santa Catarina. However, as no material of L. bahia from that state was listed by Rhyne & Lin (2006), we do not consider this map record in the currently known distribution of the species (cf. Fig. 16 View FIGURE 16 ). In addition, the specimen depicted in Rhyne & Lin (2006) ’s fig. 8C as L. ankeri might be L. bahia because of the unusually long stylocerite (see remarks under L. ankeri ).

Coelho & Ramos (1972) reported Hippolysmata (H.) wurdemanni from Brazil (“to Paraíba ”) and Rhyne & Lin (2006) listed their record under the synonymy of L. bahia . However, since Rhyne & Lin (2006) did not examine Coelho & Ramos (1972) ’s material, this synonymy remains questionable.
