Abstract
    The genus Martinichthys belongs to the order Tselfatiiformes and contains two valid species, M. brevis with a short rostrum and M. ziphioides with a long rostrum. The species M. acutus, M. alternatus, M. gracilis, M. intermedius and M. latus are junior synonyms of M. ziphioides. The genus is characterized by five autapomorphies: a snout lengthened in a rostrum, a narrow cranial roof, the premaxillae forming a secondary palate and hiding the vomer, the lack of an anterior process on the maxilla, and the supraoccipital without a median crest. Despite its specialized characters, Martinichthys also keeps some primitive features for the order, such as the presence of an autogenous basisphenoid and of three lingual toothed plates. Within the Tselfatiiformes, Martinichthys appears especially close to the genera Plethodus and Thryptodus.
