Icochilus Ameghino 1889
Description
Icochilus Ameghino, 1889
Type species (this contribution). Icochilus extensus Ameghino, 1889: 471 –472.
Comments. Ameghino (1889) did not designate the type species of genus Icochilus among the four species originally defined within this taxon. Neither Sinclair (1909), who was the first reviewer, nor Mones (1986) noticed this omission. As a result, this nomenclatural act was pending until now, because for genera described before 1930, the reviewer must select the type species among those included within the genus when it was described (ICZN 2000: Art. 69). In this case, Ameghino (1889) defined Ic. extensus, Ic. excavatus, Ic. undulatus and Ic. rotundatus along with the generic description. As there is no priority criterion regarding the pages, the priority is determined by the reviewer (ICZN 2000: Art. 69). Therefore, we choose Ic. extensus as the type species, because its type material involves an almost complete individual with reliable and recognizable dental and craneo-mandibular features. In addition, the original diagnosis of the genus was based on this species due to its completeness, and was used by Ameghino as a reference for describing the remaining three.
