Character: Body slender, precaudal tail somewhat compressed at base. Snout moderately long and pointed, eyes virtually lateral on head, subocular ridges obsolete; mouth fairly large and long, broadly arched, labial furrows moderately long, not confined to mouth corners. Pelvic fins small, low and angular; interspace between pelvic and anal bases much shorter than anal base; anal base long, origin just behind first dorsal insertion; no subcaudal crest of enlarged denticles on preventral caudal margin. No colour pattern of dark saddle blotches on body and caudal fin; dorsal fins and caudal tip with black terminal marking; mouth lining light. 
Habitat: A bottom-dwelling catshark of the continental shelves, offshore at depths of 60 to 90 m in northeastern and south western Taiwan oviparous. Maximum 45 cm, adult males 36 to 38 cm, adult females 42 to 45 cm. 
Distribution: Western North Pacific: China (Taiwan Island only), possibly the Philippines and Japan. 
Utility: Caught by bottom trawlers in Taiwan. Low economic value, use for bait of aquaculture.

Estimates of some properties based on models

Preferred temperature (Ref. 115969 ): 22 - 23.6, mean 23.2 (based on 7 cells). Phylogenetic diversity index (Ref. 82805 ):  PD 50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00316 (0.00159 - 0.00631), b=3.12 (2.95 - 3.29), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245 ). Trophic Level (Ref. 69278 ):  3.9   ±0.2 se; Based on size and trophs of closest relatives Resilience (Ref. 69278 ):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100). Vulnerability (Ref. 59153 ):  Moderate vulnerability (43 of 100) . Price category (Ref. 80766 ):   Low .
