Lysmata jundalini Rhyne, Calado & Santos, 2012

Lysmata jundalini Rhyne, Calado & Santos, 2012: 72 , figs. 1–4.

Material examined. Brazil, São Paulo: 1 ind (1 ov), MZUSP 32642 , Ubatuba, Couves Island , coll. D. Alves, vi.2013.

Distribution. Western Atlantic — Mexico (Yucatan Peninsula) to Panama, Puerto Rico, Brazil (São Paulo) ( Rhyne et al. 2012; Santana-Moreno et al. 2013; present study)

Previous records. Ubatuba, Couves Island [ Barros-Alves et al. 2016 as Lysmata cf. intermedia ( Kingsley, 1878) ].

Remarks. Barros-Alves et al. (2016) sampled two specimens of L. cf. intermedia occurring syntopically with more than 30 individuals of L. ankeri in Couves Island. One of the specimens (size 6.2 mm) was re-examined, but the other specimen reported (5.4 mm in CC) was not found in the MZUSP collection. The specimen examined by us matches L. jundalini , since it has 23 fused segments on the lateral antennular flagellum (vs. 17 fused in L. intermedia ) and 3 teeth on the dactylus of the 3rd to 5th pereiopods (vs. 4 in L. intermedia ) ( d’Udekem d’Acoz 2000; Rhyne et al. 2012). This finding extends the species distribution considerably south-westwards to São Paulo and constitute the first record from Brazil, since the previous southern limit of occurrence of these shrimps was Panama ( Rhyne et al. 2012; Santana-Moreno et al. 2013). Our record exemplifies one more case of decapod misidentified along the Brazilian coast and several, non-exclusive hypotheses may explain the low number of captured individuals such as cryptic habit, low collection efforts in the rocky subtidal areas, and recent introduction as proposed to other congeners ( Barros-Alves et al. 2016). Regarding the color pattern, we cannot discuss much based on the analyzed specimen, since there is practically no shading due to the fixation and there is no reference which specimen is (that one we examined or that one we could not find) in the photo provided by Barros-Alves et al. (2016; Fig. 1b, p . 2 ). Taking in account the photos of specimens recorded by Rhyne et al. (2012; Fig. 4, p. 76) in the original description and Santana-Moreno et al. (2013; Fig. 2C, p . 227) that recorded the species in Mexico, there is some variation of color tonality in combination with some similarity in the general aspect as translucent body with wide rust colored longitudinal stripes, lateral carapace with longitudinal strips, lacking transverse bands and dorsal carapace with heavy singular inverted U-shaped band. Molecular analyses are in progress to give more subsidies and elucidate this taxonomic field. In addition, due to the impossibility of analyzing a second specimen collected by Barros-Alves et al. (2016), the hypothesis of the occurrence of L. intermedia cannot be completely ruled out, a fact that should be investigated.
