Etymology: Spinipterus: Name derived from Latin 'spina' for spine and Greek 'pterus' meaning wing, referring to the serrated nature of fin spines; acsi: Name from ACSI, the acronym of the All Catfishes Species Inventory, a project that is supported
by the Planetary Biodiversity Inventory Program of the National Science Foundation (Ref. 87761).
Eponymy: ACSI stands for All Catfish Species Inventory. The Chrysichthys acsiorum binomial is to honour all those who are involved in achieving ACSI’s objectives. (Ref. 128868), visit book page.

Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 2; Dorsal soft rays (total): 5. The genus being monotypic, its species diagnosis is that of the genus. A genus of the auchenipterid subfamily Auchenipterinae that is distinguished from all other auchenipterid genera by the following combination of derived features: pectoral- and dorsal-fin spines with four rows of serrations running from base to the tip of the spines; (2) lateral margins of skull roofing bones ornamented with a single row of spines; (3) groove along dorsal midline posterior to dorsal fin, in which the adducted dorsal fin rests. Also the new genus has a unique combination of fin-ray meristics that are summarized as follows: D- II,4-5; P- I,5-6; V- i,5 (i,4 on opposite side); A- iv,16; C- i,7,9,i (Ref. 87761).
