It is derived from sahi ti, meaning "to be angry" or "to be brave" in Xavante language, alluding at warriors, and suchus, Latinized from the Greek souchos, an Egyptian crocodile god.

MCT 1730-R was briefly mentioned in the literature by Price and Paula-Couto (1946) and later in 1991 and 1993, but had never been figured or described before Kellner et al. (2014) assigned it to a new genus and species.

[2] Apart from Sahitisuchus fluminensis, Eocaiman itaboraiensis is the only other species formally described based on remains collected at São José de Itaboraí Basin.

A shallow elliptical depression is present near the cranio-mandibular articulation on the posterior surface of the quadrate, and the dorsal edge of supratemporal fossa is rough and rugose, as seen in Sebecus.

The jugal in Sahitisuchus is very large and ornamented, and as previously observed only in Bretesuchus, its rear ramus is higher than the anterior process and expands laterally.

As in Bretesuchus and Sebecus, it has a rough longitudinal ridge on the lateroventral edge of angular bone and dentary, that ends near the mandibular symphysis level.

As in many basal mesoeucrocodylian taxa, which includes some sebecosuchians like Lorosuchus, Sebecus, Zulmasuchus, Iberosuchus and Pepesuchus, a longitudinal frontal crest is present.

Cretaceous sebecosuchians, like Baurusuchus and Stratiotosuchus showing only five maxillary teeth, and more recent sebecosuchians (e.g. the Eocene Sebecus exhibiting nine maxillary teeth, and the Upper Miocene Langstonia), show higher skulls and a specialized, and quite reduced, dentition suggesting that only the less specialized crocodyliforms survived the Cretaceous–Paleogene extinction event (except for the marine dyrosaurids).
