Diamantiglanis is distinguished from all other genera of the Glanapteryginae-Sarcoglanidinae lineage by the following autapomorphic conditions (see discussion below): presence of a distinctive ventral process in the sesamoid supraorbital, its extremity contacting the posterolateral process of the autopalatine (Fig. 2B; vs. absence); presence of a long anteroventral process of the opercle, its length about equal to the length of the opercle main axis excluding the odontode patch (Fig. 2C; vs. about one third to half that length); presence of a minute and bifid posterior process of the vomer (Fig. 2D; vs. never a similar morphology); presence of a relatively short lateral process of the parurohyal (Fig. 2E; vs. long); and the anal-fin base posterior to the dorsal-fin base (vs. anal-fin origin at a vertical through the dorsal-fin base when both dorsal and anal fins are present). Diamantiglanis is also distinguished from all other genera of the Glanapteryginae-Sarcoglanidinae lineage by the following plesiomorphic conditions: a relatively long sesamoid supraorbital contrasting with a short lacrimal, resulting in the sesamoid supraorbital length being about thrice the lacrimal length (Fig. 2B; vs. sesamoid supraorbital short and lacrimal long, only slightly longer or smaller than the lacrimal when present) and having more opercular odontodes (opercular odontodes 15–16, vs. 1–11).</p><p>Etymology. From the Portuguese diamante (diamond) and the Greek glanis, name of uncertain origin used by Aristotle for a catfish, an allusion to the occurrence of the new genus in Chapada Diamantina, northeastern Brazil, an important diamond mining center in the past. Gender masculine.</p><p>Included taxa and distribution. Only one species, D. multidentatus from the Rio Paraguaçu basin, Chapada Diamantina, northeastern Brazil (Fig. 3).</p></div>	https://treatment.plazi.org/id/039487B6FF95FFBF25FF6026FDC9F82D	Public Domain	No known copyright restrictions apply.
