It is also a member of the Chanoidei, as indicated by the presence of a large, very broad, concave-convex premaxilla, with a long oral process (C.27:1), the presence of a maxilla posteriorly swollen to a bulbous outline (C.33:1), quadrate-mandibular articulation anteriorly displaced (anterior to the orbit) (C.48:1), symplectic elongated (C.49:1), metapterygoid process of hyomandibular present on its anterior border (C.52:1) (Fig. 6), opercular bone expanded to at least one third of head length (C.54:1), and suprapreopercular bone present as a relatively large, flat bone (C.62:1) (Fig. 7).</p><p>The inclusion of D. moraesi in the Chanidae (Node 4) is supported by several synapomorphies, such as: presence of a large, very broad, concave-convex premaxilla with a long oral process (C.27:1); the posterior region of the maxilla very enlarged, swollen and having a bulbous outline, with curved posterior border (C.33:1); quadratemandibular articulation located anterior to orbit, with the quadrate displaced but not elongate (C.48:1); presence of an elongated symplectic (C.49:1); presence of a metapterygoid process of hyomandibula (C.52:1); presence of an expanded opercular bone, with at least one third of the head length (C.54:1); by having an preopercular expansion present on preopercle posteroventral corner and part of the posterodorsal limb (C.61:1); and the presence of autogenous hemal arch in preural centrum 2 (C.103:1).</p><p>Our analysis indicated that the Chanidae is divided in two clades: Rubiesichthys + Gordichthys (Node 5, subfamily Rubiesichthyinae), and Nanaichthys + ( Aethalionopsis + ( Parachanos + ( Dastilbe + ( Tharrhias + ( Dastilbe moraesi + Chanos)))))) (Node 6, subfamily Chaninae). The Node 5 is supported by three synapomorphies: dorsal and ventral borders of the maxillary articular process very curved (C.31:1); angle formed by preopercular limbs acute (C.58: 2); and posterior process on the posterior border of first supraneural present (C.83:1). The Node 6, in turn, is supported by the presence of a maxillary process for articulation with the autopalatine (C. 32:1), and by the presence of a ridge on the anteroventral limb of the preopercular bone (C.60:1).</p><p>Nanaichthys, according to our analysis, is the sistergroup of the clade formed by the remaining taxa included in Node 6, forming together the subfamily Chaninae.</p><p>Dastilbe crandalli is the sister-group of Chanini (including Tharrias, Dastilbe moraesi and Chanos) based on the presence of the anterodorsal border of the dentary slightly concave, forming a relatively high symphysis (C.35:1).</p><p>The inclusion of Dastilbe moraesi within the Chanini (including Tharrhias and Chanos) is based on the presence of exoccipitals with a posterior concave-convex border, with a projection above the basioccipital (C.5:1), a large mesethmoid with broad posterolateral wing-like expansions (C10:1), and the presence of a neural arch and spine of the first preural centrum both well developed, with the spine about half as long as preceding ones (C.92:1) (Fig. 8).</p><p>The sister group relationship between Dastilbe moraesi and Chanos (Node 11) is supported by the presence of the posterolateral expansion of exoccipitals (C.4:1), and the absence of postcleithra (C.85:1). Dastilbe moraesi is phylogenetic diagnosed from the remaining Chanidae by the autapomorphic condition of its caudal-fin skeleton, characterized by the presence of only five hypurals (Fig. 9).</p></div>	https://treatment.plazi.org/id/597E87EA160F2C4D92B8FF7CFA2EFE73	Public Domain	No known copyright restrictions apply.
