Remarks. Lysmata bahia was first reported from Brazil by Fausto Filho (1970) as Hippolysmata wurdemanni Gibbes, 1850 , followed by the first occurrence in São Paulo as Lysmata wurdemanni ( Gibbes, 1850) by Chace (1972), which were later considered paratypes of L. bahia by Rhyne and Lin (2006). It is also one of the three species that belongs to the L. wurdermanni complex in Brazil, along with Lysmata ankeri Rhyne and Lin, 2006 and L. wurdermanni (see Pachelle et al., 2020). The analyzed specimens presented all the diagnostic characteristics of L. bahia , according to Pachelle et al. (2020). The two specimens presented long stylocerites, almost reaching the distal margin of the first article of the antennular peduncle, which is a characteristic that differentiates L. bahia from L. ankeri and L. wurdemanni (which have a comparatively shorter stylocerite) ( Pachelle et al., 2020). However, the two specimens presented the carpus of the first pereiopod about 4 times longer than tall, instead of 4.5 times,as indicated by Pachelle et al. (2020).
