(Figure 8)  
 Lysmata jundalini Rhyne, Calado & Santos 2012: 72, figs. 1–4.   
 Not Lysmata jundalini — Terossi et al. 2018: 83 [= L. intermedia (Kingsley, 1878), see above].   
 Material examined. Brazil: 1 non-ov. specimen (pocl 4.1 mm), MZUSP 34362, Espírito Santo, Guarapari, Escalvada Island, depth 15 m, coll. J.L. Gasparini, 19.i.1997.   
 Comparative material. Lysmata jundalini (Figures 9, 10). Panama: 4 non-ov. specimens (pocl 5.7–4.0 mm), MZUSP 31046, Bocas del Toro, Isla Bastimentos, Coral Cay, coll. C. Tavares, 06.viii.2008; 1 non-ov. specimen (pocl 3.7 mm), MZUSP 33775, Bocas del Toro, Isla Colón, Boca del Drago, shallow flat with seagrass and coral rubble, in coral ruble, depth 0.5–2 m, coll. A. Anker et al., 01.v.2015; 3 non-ov. specimens (pocl 4.1–4.0 mm), MZUSP 33924, Bocas del Toro, Isla Colón, Punta Caracol, in coral rubble, depth 0.5–2 m, coll. A. Anker et al., 27.iv.2015; 1 non-ov. specimen (pocl 3.5 mm), MZUSP 38019, Bocas del Toro, Isla Bastimentos, Playa Polo, coral rubble, coll. A. Anker et al., 29.iv.2015; 1 non-ov. specimen (pocl 3.2 mm), FLMNH UF 51814, Bocas del Toro, between Bastimento and Solarte, 9º20’18.7’’N 82º13’02.8’’W, rocky bottom, inside rock, depth 4–6 m, coll. M. Leray et al., 29.iii.2019; 3 non-ov. specimens (pocl 5.0– 3.2 mm), MZUSP 31937, Venezuela, Isla de Cubagua, in Millepora sp., coll. N. Castro, 2001–2002.   
 Remarks. A single specimen from Guarapari, Espírito Santo (MZUSP 34362), corresponds to L. jundalini in most taxonomically important morphological characters, including the number of subdivisions in the fused portion of the lateral antennular flagellum and the relatively longer first pereopod carpus (Fig. 8; see also Rhyne et al. 2012: fig. 3a). However, this specimen was collected at a depth of 15 m, possibly on rocky or mixed bottom, which differs from the typical habitats of L. jundalini in the Caribbean Sea, i.e. shallow subtidal flats dominated by sea grass and coral rubble (A. Anker, pers. obs.). Due to the lack of any information on the colour pattern of the Guarapari specimen (field notes or colour photographs), we tentatively assigned it to L. cf. jundalini, awaiting a molecular analysis of the Guarapari specimen and/or collection of more material.   
 The relative proportions of the first pereopod carpus may represent the most consistent morphological difference between L. jundalini (4.5–5.0 times as long as high) and L. intermedia (3.0–3.5 times as long as high). The redescription of L. intermedia by d’Udekem d’Acoz (2000) is somewhat problematic for his illustrations were made using several older specimens, without any information on their colour pattern or ecology. For example, the proportions of the first pereopod carpus of the specimens illustrated by d’Udekem d’Acoz (2000: fig. 3A) are more similar to those of L. jundalini, whereas the number of subdivisions in the fused portion of the lateral antennular flagellum (idem.: fig. 2C, in the text: 9–17) is typical for L. intermedia. Therefore, it cannot be excluded that this author had both L. jundalini and L. intermedia in his material.
