Comments.

Identification of present specimens is based on diagnosis provided by Kritsky et al. (2009b) which transferred this species from Haliotrema  to Haliotrematoides  on the basis of study of Zhukov’s (1976) original figures and those provided by Bosques-Rodríguez (2004). This species is characterized in having an inner spur on the dorsal anchor shaft and shaft of MCO having a proximal loop (see Kritsky et al. 2009). Haliotrematoides cornigerum  is currently reported from L. synagris  and L. mahogoni  from the Bay of Campeche (Area Havana) and Puerto Rico ( Zhukov 1976, Bosques-Rodríguez 2004, Kritsky et al. 2009b). Recently, Montoya-Mendoza et al. (2016) reported E. cornigerum  (voucher CNHE 10217), from L. synagris  from Santiaguillo Reef, Veracruz (Gulf of Mexico). Examination of that voucher allowed us to confirm the species identity.

Specimens deposited.

Six reference specimens in the CNHE (10603).
