📖 Overview
Pseudecheneis Stenura (Pseudecheneis stenura), first described by Ng, 2006 is a medium-sized fish in the family Sisoridae (order Siluriformes). Adults typically reach 18.00 cm in maximum length. It inhabits freshwater systems including rivers, streams, and lakes. It occurs in Tropical waters. It is broadly omnivorous, taking invertebrates, plant matter, and detritus.
🔬 Taxonomy
🐟 Physical Description
Dorsal soft rays (total): 7; Anal soft rays: 9 - 12; Vertebrae: 37 - 40. Can be separated from different species of the genus Pseudecheneis by having the following characters: pelvic fin reaching base of the first anal-fin ray (vs. not reaching in Pseudecheneis sulcata); pectoral fin reaching origin of pelvic fin (vs. not reaching in Pseudecheneis crassicauda; length of adipose- fin base 125-166.7% in length of anal-fin base (vs. longer than 200% in Pseudecheneis serracula); separate pelvic fins (vs. fused in Pseudecheneis sympelvica); thoracic apparatus with 15-19 transverse ridges/laminae (vs. 9-13 in Pseudecheneis paviei); deeper forked caudal fin, shortest ray of caudal fin circa 50% of longest ray (vs. 75% in other congeners, except Pseudecheneis gracilis). Distinguished from Pseudecheneis gracilis in having the following features: two ovoid yellow patches on dorsal fin (vs. a saddle patch); head length 20.1-23.7% SL (vs. 14.9-18.6); postorbital head length 8.5-11.4% in head length (vs. 4.5-5.9); and body depth 67.1-88.5% in head length (vs. 73.9-112.2%). Other useful distinguishing characters include the following: premaxillary tooth band semicircular and two or four teeth along its outer edge; body covered with dense, rounded tubercles distributed irregularly; tubercles decreasing in density gradually from occipital to caudal peduncle with almost no tubercles; and vertebrae 39 . : elongated.
