Breitensteinia cessator Ng & Siebert 1998

Identification: Breitensteinia cessator is long and slender with a long low adipose ridge but no adipose fin, low neural spines in the caudal vertebrae, a long and slender caudal peduncle (31-37%% SL), a relatively large eye (4-5% head length), the gill opening not extending above the pectoral fin base, 11-12 principal caudal rays, 5 branchiostegal rays, and 44-45 vertebrae. The broad, depressed head is covered with small, indistinct tubercles. Tubercles on the body are arranged in 5-6 horizontal rows on both sides. The anterior nostril is tubular, and the caudal fin has a straight posterior margin. The narrow occipital process reaches the predorsal plate. The posterior edge of the pectoral spine has 8-16 large serrae. Body and head dark brown above with scattered light brown spots, light brown to cream-colored below with few brown spots. Brown spots evenly scattered on the dorsal and pectoral fins. Dark brown bands and pelvic, anal and caudal fins. To 8 in. (20 cm) total length.

Range: This species is found in the Batang Hari and Tulangbawan River drainages in Sumatra and the Kapuas River drainage in western Borneo.

Habitat: B. cessator is found among woody debris in current in small to medium-sized rivers.

Similar species: B. hypselurus has a smooth posterior edge on the pectoral spine, a shorter caudal peduncle (26% SL), tall neural spines in the caudal vertebrae, and 42 vertebrae. B. insignis has a smaller eye (2-3% head length) and brown spots concentrated in marginal bands on the dorsal and pectoral fins.
