Relevant Information:

Description: Dorsal soft rays (total): 7; Anal soft rays: 11 - 12; Vertebrae: 37 - 39. Excluding Pseudecheneis paviei, Pseudecheneis sulcatoides, and Pseudecheneis sympelvica, this species differs from other all congeners by the absence of a prominent bony spur on the anterodorsal surface of the first dorsal-fin pterygiophore. Can be separated from these three species by the combination of the following characters: body elongate with 36-39 vertebrae; thoracic adhesive apparatus with 12-14 transverse laminae; separate pelvic fin; caudal peduncle length 25.0-28.3% SL; presence of a first-dorsal element; complex vertebra with bifid neural spines. Additional characters useful to distinguish this species include: caudal-peduncle depth 4.0-5.2% SL; eye diameter 8.8-10.6% HL; pelvic-fin length 21.2-28.7% SL; length of adipose-fin base 17.8-22.7%; body with pale colored patches; neural spines of the last 2-3 preanal and first 6-7 postanal vertebrae gradually increasing in height; pectoral fin length 121.6-156.3% HL; and vertebrae 37. Habitat: Found in fast-flowing hill streams. Prefers deep riffles and runs over gravel, cobble substrates. Etymology: The specific name sulcata: Latin for furrowed or grooved, probably referring to oval adhesive disk on breast, “composed of transverse plates”.

IUCN Red List

Although there is insufficient information on population (and its trends), and biology of this species, indications from current surveys are that this is still a relatively widely distributed and abundant species. Pseudecheneis sulcata is therefore assessed as Least Concern, needs updating (IUCN 2021).
