Etymology: Hassar: Origin of the name was not specified by the author, but it is possible that it refers to the name commonly applied to certain catfishes in Guyana, such as Hoplosternum littorale or Hypostomus watawata; shewellkeimi: Named for Mr. Shewell 'Bud' DeBenneville Keim, a nephew of Henry W. Fowler, who was the first full-time curator of fishes at the Academyof Natural Sciences from 1902-1965, for his generous support to Academy ichthyology, including the preservation of Fowler's legacy and the stewardships of his uncle's fishes.
Eponymy: Shewell ‘Bud’ DeBenneville Keim (1918–2014), after serving in the US Army in WW2, graduated as an electrical engineer (1949) and spent his working life as an electronics engineer in the US Defense Department. [...] (Ref. 128868), visit book page.

Duri punggung (Keseluruhan (total)) : 2; duri punggung lunak (Keseluruhan (total)) : 6; Sirip dubur lunak: 12 - 15. This species differs from other species of Hassar by its relatively narrow interorbital and long snout, interorbital width 32.2-44.7% distance from snout tip to anterior naris (vs. 45.0-89.4%). It is most similar to H. orestis, but it can be further separated from that species by having gas bladder with few, weakly developed peripheral diverticula restricted to anterolateral shoulder and posterolateral face of anterior chamber, and sometimes anterolateral face of posterior chamber (vs. well developed diverticula with multiple branches and grouped into fascicles encircling horizontal periphery of gas bladder in H. orestis), and posterior face of gas bladder smooth, broadly to narrowly rounded (vs. posterior chambers expanded posteriorly into medially conjoined ternimal diverticula, effecting acutely subtriangular, cone-shaped posterior face). This species also differs from H. affinis and H. gabiru by its snout, distance snout tip to anterior naris 9.5-12% SL (vs. 6.9-9.7% SL), interorbital width 3.4-4.8% SL and 9.8-14.7% HL (5.9-8.0% SL and 17.3-24.3% HL), and caudal peduncle depth 4.8-5.6% SL (vs. 6.6-8.0% SL). It is diagnosed from all congeners except H. orestis by the distal half of soft dorsal fin consisting of distinct dark subtriangular blotch not extending to distal margin, pale margin complete, its width approaching that of blotch (vs. distal half of soft dorsal dfn dusky to margin in H. affinis; or with dark blotch leaving narrow pale distal margin, width less than half that of dark blotch, in H. gabiru, H. wilderi and sometimes H. orestis) (Ref. 93284).
