description: <i>Hassar</i> Eigenmann &amp; Eigenmann, 1888 <i>Hassar</i> Eigenmann &amp; Eigenmann, 1888: 158 [type species: <i>Oxydoras orestis</i> Steindachner 1875, by subsequent designation by Eigenmann 1910: 394]. Gender masculine. Originally proposed as a subgenus of <i>Hemidoras</i>. <b>Diagnosis.</b> <i>Hassar</i> is diagnosed by a single exclusive character: basioccipital with a ventral ring-like arch surrounding aorta (Fig. 1); and by the combination of the following non-exclusive characters: 1) dark blotch in the middle to distal region of anterior branched rays of dorsal fin; 2) anteriormost postinfranuchal scutes reduced in size; 3) pores beneath the posterior cleithral process numerous; 4) maxillary barbels with 7 to 16 secondary barbels, and fleshy papillae restricted to anteriormost secondary barbels; 5) elongated mesethmoid, with lanceolate anterior tip and straight to slightly convex dorsal profile; 6) posterior cranial fontanel relatively large, extending posteriorly into the parietosupraoccipital; 7) first infraorbital long and slender, with dilated anterior extremity, articulating with the lateral border of mesethmoid; 8) ossified and extremely well-developed epioccipital process, sutured to the posterior nuchal plate; 9) less than 10 premaxillary teeth; 10) less than 20 dentary teeth; 11) well-developed nuchal foramina; 12) reduced anterior nuchal plate, enclosed by the posterior margin of the parietosupraoccipital and anterior margin of the middle nuchal plate; 13) 30 to 34 midlateral scutes on each side of body. See Discussion for additional notes on the aforementioned diagnostic features. <b>Etymology.</b> Eigenmann &amp; Eigenmann (1888) did not specify the origin of <i>Hassar</i>, but it possibly refers to the name commonly applied to certain catfishes in Guyana, such as <i>Hoplosternum littorale</i> or <i>Hypostomus watawata</i> (Eigenmann, 1912).
