Upper labial furrows falling behind lower symphysis; lower anterior and lateral teeth with low cusplets present on distal crown feet; lateral teeth with mostly erect cusps. Caudal vertebral centra 55 to 56, total vertebralcounts 131 to 135.
? Western Pacific: Viet Nam, southern China (off Hong Kong), and Taiwan Island, Japan.
Habitat and Biology:
A little-known inshore shark, depth range not reported.
Adult males 78 to 88 cm long.
Interest to Fisheries:
Taken in Taiwan Island, Hong Kong, and Japanese fisheries, and probably elsewhere where it occurs.
Synonymy and generic placement of this species follows Compagno (1979). Fourmanoir (1961) described a tengi-like shark from off Madagascar as Paragaleus pectoralis, but this may be an undescribed Paragaleus recently collected from off South Africa.
Syntypes: Tunghai University fish collection, Taiwan Island (Province of China), THUP 01802, 810 mm adult male, THUP 01803, 750 mm male, and THUP 01804, 770 mm male. Type Locality: Taichung Market, Taiwan, Province of China.
