Scientific Name with Original Description
Cirrhoscyllium formosanum  Teng, 1959b, Taiwan Fish. Res. Inst., Keelung, Lab. Fish. Biol. Rep., (7): 1, pl. 1. Holotype: Taiwan Fisheries Research Institute, TFRI 3574, 367 mm female, off Kao-hsiung, Taiwan (Province of China), 110 m.
Diagnostic Features
fieldmarks: Barbels on throat, nasoral grooves, mouth in front of eyes, six diffuse saddle marks on dorsal surface, saddles above abdomen rounded and continuing above pelvic-fin bases, not C-shaped, head length 2.3 to 2.6 times first dorsal-fin base.

Head length 2.3 to 2.6 times first dorsal-fin base. Anal-caudal space 6.8 to 7.7% of total length, 38 to 45% of head length. Second dorsal-fin base equal to or longer than anal-caudal space.  Precaudal vertebral count 112 to 117, total count 159 to 167.  Six pairs of indistinct saddle markings on sides of back and tail; an elongated rounded saddle on each side of back between bases of pectoral and pelvic fins and extending over pelvic-fin bases. 
Geographical Distribution

Launch the Aquatic Species Distribution map viewer

Western North Pacific: Taiwan Island (Province of China).
Habitat and Biology
Outer shelf of Taiwan (Province of China) at depth of about 110 m.

A little-known small, tropical or subtropical shark, biology essentially unknown. Twelve specimens (11 paratypes and the holotype) are in the Taiwan Fisheries Research Institute, all collected off Kao-hsiung, Taiwan (Province of China). That all the paratypes were collected in one day on longlines suggests that the species may be or was common although possibly localized.
Size
Maximum 39 cm; eight males 35.2 to 37.7 cm; one paratype male 35.9 cm TL from this series was adult according to Goto and Nakaya (1996), and presumably the larger males were also mature. Females 35.2 to 38.5 cm possibly adult if adult females attain a size similar to Cirrhoscyllium expolitum.
Interest to Fisheries
Interest to fisheries unknown, taken on bottom longlines off Taiwan (Province of China), presumably also as discarded trawl bycatch.

Conservation Status : Conservation status unknown.
