Fig. 16

Pseudecheneis Blyth, 1860   ZBK : 154. (Type species: Glyptothorax sulcatus McClelland, 1842 , by monotypy). Gender feminine.

Parapseudecheneis Hora, in Hora & Chabanaud, 1930   ZBK : 216. (Type species: Pseudecheneis paviei Vaillant, 1892   ZBK , by monotypy). Gender feminine. Synonomized with Pseudecheneis   ZBK by Chu (1982).

Propseudecheneis Hora, 1937   ZBK : 348. (Type species: Propseudecheneis tchangi Hora, 1937 , by original designation). Gender feminine. Synonomized with Pseudecheneis   ZBK by Chu (1982).

Diagnosis: Thoracic adhesive apparatus with grooves transverse to longitudinal axis of body (vs. grooves parallel or oblique to longitudinal axis of body, or thoracic adhesive apparatus absent).

Pseudecheneis   ZBK is distinguished from all other sisorid genera by having an adhesive apparatus on the thorax with grooves transverse to the longitudinal axis of the body (vs. thoracic adhesive apparatus with grooves parallel or oblique to the longitudinal axis of body in Glyptothorax   ZBK , and the thoracic adhesive apparatus absent in all other genera).

Description: Dorsal fin with 1 spine, 5-7 branched rays; pectoral fin with 1 spine, 11-16 rays; 6 pelvic-fin rays, 4-13 anal-fin rays. Head short, anteriorly depressed; snout sharp; body elongate, moderately or greatly depressed. Eyes small, dorsal. Skin smooth. Mouth small. Lips thick, fleshy, papillate. Jaw teeth somewhat flattened with truncate apices in small patches on jaws; palatal teeth absent. Eyes small, dorsal. Maxillary barbel very short, barbel, with well-developed membrane, soft base. Mandibular barbels papillate. Gill openings narrow; branchiostegal membranes confluent with isthmus. Coracoid process not visible externally. Thoracic adhesive apparatus present, grooves transverse to longitudinal axis of body. Paired fins plaited (Fig. 15) to form an adhesive apparatus.

Distribution: Ganges and Brahmaputra drainages, northern India and Nepal, east to the Red River drainage, Vietnam (Ng & Edds, 2005b).
