Short description Morphology | Morphometrics

Dorsal spines (total): 2; Dorsal soft rays (total): 6-7; Anal spines: 0; Anal soft rays: 10 - 12; Vertebrae: 35 - 37. Body compressed (Ref. 52369). Predorsal profile gently convex; postdorsal body sloping gently ventrally (Ref. 52369). Head depressed and broad, acutely rounded when viewed laterally and with rounded snout margin when viewed from above (Ref. 52369). Eye large and ovoid, horizontal axis longest (Ref. 52369). Mouth inferior and crescent-shaped; lips plicate (Ref. 52369). Barbels in three pairs; maxillary barbel long and slender, extending to just beyond base of last pectoral-fin ray; inner mandibular-barbel origin close to midline, extending to base of pectoral spine and with 2 short, thin branches on anterior half and 3-5 long, thin branches on posterior half; outer mandibular barbel originates posterolateral of inner mandibular barbel, extending to middle of pectoral-fin base and with 3-5 long, thin branches (Ref. 52369). Gill openings narrow, extending from immediately ventral to posttemporal to immediately ventral to baes of pectoral spine (Ref. 52369). Supracleithral process thin and longer tha in other Microsynodontis species (Ref. 52369). Dorsal fin located at anterior third of body, with convex margin; dorsal-fin spine long, stout and slightly curved, smooth on both anterior and posterior margins (Ref. 52369). Adipose fin moderately long; margin slightly convex for entire length and posterior end deeply incised (Ref. 52369). Caudal fin rounded, with i,6,6,i principal rays (Ref. 52369). Anal-fin base located ventral to posterior half of adipose fin, with iii-iv,7-8 rays and convex margin (Ref. 52369). Pelvic-fin origin at vertical ventral to posterior end of dorsal-fin base, with slightly convex margin (Ref. 52369). Pectoral-fin spine slightly curved and stout; anterior spine margin with 22-28 small serrations along entire length of spine, serrations antrorse on distal two-thirds and anteriorly directed on proximal third; posterior spine margin with 8-13 strong serrations along entire length (Ref. 52369). Lateral line complete and midlateral (Ref. 52369). Dorsal and lateral surfaces of head and body dark chocolate brown, fading to light brown on belly in preserved specimens (Ref. 52369). Snout with a series of light yellow spots delineating anterior and posterior nares; cheek region with one or two light yellow spots immediately ventral to orbit; light yellow band encircling nape at supraoccipital (Ref. 52369). Dorsal third of body with series of four light yellow vertical bar-shaped marks extending to lateral midline of body: first at middle of dorsal-fin base, second at adipose-fin origin, third at middle of adipose-fin origin and last on caudal peduncle immediately posterior to adipose fin (Ref. 52369). Ventral third of flanks with a longitudinal series of four to seven light yellow spots or vertical bar-shaped marks (Ref. 52369). Dorsal fin with dark chocolate brown base and on or two rows of elongate spots forming longitudinal dark chocolate brown rows; pectoral, pelvic and anal fins with hyaline bases and similarly marked; caudal fin hyaline, with elongate brown spots forming two or three irregular columns (Ref. 52369).
