Abstract: Enchiridium evelinae Marcus, 1949 Fig. 5 C, D Material examined. Yucatan coast, Mexico • 1; Bajos de Sisal; 21.2°N, 90.0°W; 1 m; 10 Sep. 2017; A. Hernández leg.; CRPPY -0033. Distribution. Recorded in São Paulo (Marcus 1950), Rio Grande do Norte, and Alagoas (Bahia et al. 2012, 2014, 2015; Bahia and Schrödl 2018) in Brazil and Panama (Rawlinson 2008). It is also known in Curaçao (Marcus and Marcus 1968). This work represents a new record for the Yucatan coast. New record for the Gulf of Mexico. Description. Body shape elongated, 3 cm in length and 1 cm in width. Body cream-coloured with brown, orange, and yellow spots arranged densely along the midline and paler towards the margins (Fig. 5 C, D). Tubular pharynx extends to ~ 1 / 3 of the body’s length. Reproductive male apparatus with an enclosed seminal vesicle and two prostatic vesicles included in a common muscular bulb, and a long penis papilla armed with a stylet opening in a long male atrium. Remarks. The spots disappear after fixation and, according to Marcus (1950), the pigmentation of these spots is lipoid (Fig. 5 C, D). The specimens recorded here have a lower density of dots compared to the specimens described in Bahia et al. (2014: fig. 14).
