Pseudomurraytrematoides n. gen.

Synonymy: Murraytrematoides Yamaguti, 1963 , partim.

Diagnosis: With the characteristics of the subfamily.

Type species: Pseudomurraytrematoides pricei ( Caballero, Bravo-Hollis & Grocott, 1955) n. comb. from Cynoponticus coniceps ( Jordan & Gilbert) ( Muraenesocidae ).

Remarks: From the five species of Murraytrematoides recognized by Oliver (1987), only M. ditrematis (type species), M. lateolabracis and M. pricei were available for study. The comparative analysis of the reproductive structures and the cladistic analysis suggest that the studied specimens are not congeneric. Murraytrematoides pricei shows a simple male copulatory organ (MCO), accessory piece, and genital pore opening posterior to MCO. Murraytrematoides ditrematis and M. lateolabracis have MCO formed by nested tubes, genital pore opening anterior to the MCO, and the absence of accessory piece. In the cladistic analysis, M. pricei appears as basal within Diplectanidae , sister group of clade “C”, while M. ditrematis and M. lateolabracis appear in a polytomy with Anoplectanum (clade “V”). Thus, we propose to accommodate M. pricei , as Pseumurraytrematoides pricei n. comb., a member of the new subfamily. The generic name is from Greek (pseud/ o = false) and refers to the fact that members of this genus are not congeneric with Murraytrematoides , as presented herein.
