Left P 5 with elongate Exp 2, with concave inner margin furnished with setules, and outer distal spine; Exp 3 short, armed with 3 elements: inner medial spine, terminal pointed process with row of spinules, and outer spine. Distribution. This species was originally described from Airstrip Caves, Discovery Bay, Jamaica, and it is the second cave-dwelling calanoid copepod recorded from anchialine systems of the YP, after Stephos fernandoi Suárez-Morales, Gutiérrez-Aguirre, Cervantes-Martínez and Illife, 2017 (Suárez-Morales et al. 2017 b), and the third calanoid copepod found in Cozumel Island, where an epigean freshwater diaptomid Mastigodiaptomus ha Cervantes, 2020 was also reported (Cervantes-Martínez et al. 2021). Remarks. We identified this species as E. rubra by possession of the following structures that agree with its original description: both female and male individuals had a reddish color before fixation; rostrum with long filaments near distal tip of rostral base; the antenna has exopod segments compressed; mandible with raptorial gnathobase, mandibular palp with unarmed triangle-shaped basis, and small unsegmented endopod distally placed to basis, with two unequal setae; maxilla and maxilliped with long basis; armature of thoracic legs as originally described. Male fifth legs with 3 rd exopods and left fifth leg 2 nd exopod, partially modified. Female P 5 unmodified, but with 2 - segmented exopods and endopods in both rami, based on a single specimen. In addition, we found some morphological differences of the YP E. rubra with respect to the original description, including: (1) the integument of all body parts is covered with minute scale-like spinules, a character not reported before; (2) rostrum with relatively shorter filaments with a patch of setulae like elements (Fig. 2 B), instead of the large pores described for the Jamaican specimens (Fosshagen et al., 2001: Figs. 1 C, 14 A); and (3) female fifth leg with 2 - segmentedramus. Weidentifiedsomeornamentation details that were not recorded previously, like: (1) the accessory spines on the proximal area of the mandibular gnathobase; and (2) male left fifth leg Exp 2 with inner setules.	en	Mejía-Ortiz, Sarahi Jaime Eduardo Suárez-Morales Adrián Cervantes-Martínez Martha A.

Bofuriella spinosa is known from its type locality in Middle Caicos Islands (Fosshagen and Iliffe, 2007), with previous records in Turks and Caicos Islands (Gonzalez et al., 2020). This is the first record of B. spinosa outside its type locality and in caves of the Mexican Caribbean, also, the third epacteriscid reported from the YP (see Suárez-Morales et al., 2006). Remarks. Currently, only three species of Bofuriella are known for the Caribbean Sea (see Appendix – Tab. A 1), including Bofuriella vorata Fosshagen, Boxshall and Iliffe, 2001 and Bofuriella paravorata Fosshagen and Iliffe, 2007 from Bahamas (Fosshagen et al., 2001; Fosshagen and Iliffe, 2007). We identified our specimen as member of Bofuriella by following the emended generic diagnosis by Fosshagen and Iliffe (2007: 85): (1) antennary endopod almost 2 / 3 as long as the exopod and has a well-developed inner lobe; (2) mandibular palp with 2 - segmented endopod, with 2 – 5 setae; (3) maxilla with well-developed praecoxal and coxal lobes on. We also identified this male individual as B. spinosa by its possession of (1) a short seta on exopod 1 of the antenna; (2) 5 setae on the endopod of the mandibular palp; and (3) large spines on leg 1 exopodal segments. Based on the male description of B. spinosa from Mexico, we identified the following structures that allowed us to distinguish this species from its congeners B. vorata (see Fosshagen et al., 2001: fig. 26 C) and B. paravorata (see Fosshagen and Iliffe, 2007: fig. 8 C, D), for example: (1) exopod 2 of right fifth leg with long ramus that reaches beyond exopod 3; (2) exopod 3 of right fifth leg has three well differentiated thick spinal elements; (3) left fifth leg basipod with inner sinusoid spinous process, compared to the strong projection as described for both congeners; (4) exopod 3 of left fifth leg elongated and slender, with 2 unequal setae and terminal papules; and (6) endopod 3 of left fifth leg without the known row of flattened spinules. These comparisons along with other structures are shown in Tab. A 2 (Appendix) in more detail. We also provide a key of Bofuriella species.	en	Mejía-Ortiz, Sarahi Jaime Eduardo Suárez-Morales Adrián Cervantes-Martínez Martha A. Gutiérrez-Aguirre Luis M.
