Mayarhynchus

edit
Main article: Mayarhynchus

The genus Mayarhynchus Pinacho-Pinacho, Hernández-Orts, Sereno-Uribe, Pérez-Ponce de León & García-Varela, 2017 is different from the other 17 genera in Neoechinorhynchidae by having a small proboscis. It has nine longitudinal rows of five hooks each, totaling 45 to 46 relatively weak rooted hooks.[3] It contains only one species: Mayarhynchus karlae Pinacho-Pinacho, Hernández-Orts, Sereno-Uribe, Pérez-Ponce de León & García-Varela, 2017.[3]

Atactorhynchus

edit
Main article: Atactorhynchus

Atactorhynchus Chandler, 1935 has two species:

  • Atactorhynchus duranguensis Salgado-Maldonado, Aguilar-Aguilar and Cabañas-Carranza, 2005

A. duranguensis has been found in the intestine of the Mezquital pupfish (Cyprinodon meeki) a fish from in-land Mexico. Diagnostic features include: body small, stout, ventrally curved; small cylindrical proboscis armed with 16 alternating vertical rows of four or five hooks; anterior two or three hooks conspicuous, stout and larger than other hooks, and have large, rod-shaped roots with a markedly and abruptly enlarged base; three posterior hooks of each row are smaller and rootless; single-walled proboscis receptacle; lemnisci equal in length, elongate and robust; and cement gland syncytial, larger than testis. The new species is smaller than A. verecundus with smaller hook lengths and slightly smaller proboscis. A. duranguensis is also shaped differently: it has a proboscis shape that is not widest at the apex, and the greatest width of the trunk is in about the middle contrasting A. verecundus where the trunk is widest posteriorly, and the proportion of large apical proboscis hooks in relation to the small basal hooks is different: the basal hooks of A. verecundus are about half the size of the anterior hooks and but only about a quarter of the size in A. duranguensis. Unlike A. verecundus, the base of the roots are markedly and abruptly enlarged in the new species. Finally, the eggs of the new species are smaller (23-27 x 8-10 um) than those of A. verecundus (27-30 x 12-13 um).[4]
