039487B6FF95FFBF25FF6026FDC9F82D.taxon	diagnosis	Diagnosis. 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. 2 B; 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. 2 C; vs. about one third to half that length); presence of a minute and bifid posterior process of the vomer (Fig. 2 D; vs. never a similar morphology); presence of a relatively short lateral process of the parurohyal (Fig. 2 E; 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. 2 B; 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).	en	Costa, Wilson J.

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. Included taxa and distribution. Only one species, D. multidentatus from the Rio Paraguaçu basin, Chapada Diamantina, northeastern Brazil (Fig. 3).	en	Costa, Wilson J. E.
