Taiwan voucher material: (6 spec.) CAS uncatalogued (TAI-158), juvenile male 511 mm TL, CSIRO H 6295-20 , juvenile male 495 mm TL , UF 159314, female 404 mm TL, Da-xi, 24 May 2005 ; AMNH 258165 , juvenile male 313 mm TL, Da-xi, 15 Mar 2012 ; MNHN 2013-0462 (tissue accession GN10099 ), female 542 mm TL , CAS 236048 (tissue accession GN10100 ), juvenile male 443 mm TL, Dong-gang, Mar 2012 .

Remarks: The most abundantly caught shark in coastal fisheries in northern and western Taiwan; catch statistics not available as not sold through the regular market system ( Chen et al., 2007). Records of Chiloscyllium indicum from Taiwan appear to refer to this species; historically was referred to as C. colax in Taiwan.

Conservation status: Near Threatened.

Brownbanded Bamboo Shark / ºĠṖḛ

Chiloscyllium punctatum Müller & Henle, 1838c: 18 , pl. 3. Neotype: AMNH 38153 , female 352 mm TL, off Jakarta, Java Sea , Indonesia, 23 Mar 1940.

Local synonymy: Chiloscyllium punctatum: Nakamura, 1936: 15 , pl. 5, fig. 2; Chen, 1948: 27; Chen, 1956: 14; Teng, 1962: 68, fig. 17; Chen, 1963: 21, fig. 6 (THUP 1970); Shen, 1984a: 33, fig.; Chen & Yu, 1986: 122; Chen & Joung, 1993: 47, pl. 4 (fig. 4); Chen, 2004: 20; Shao et al., 2008: 236; Shen & Wu, 2011: 56, fig.

Taiwan voucher material: (4 spec.) HUMZ 213818 (tissue accession GN10102 ), juvenile male 492 mm TL, HUMZ 213819 (tissue accession GN10103 ), juvenile male 528 mm TL, MNHN 2013-0463 (tissue accession GN10101 ), female 542 mm TL, CAS 236048 (tissue accession GN10104 ), female 572 mm TL, 22°26'N, 120°30'E, Dong-gang, Mar 2012 .

Remarks: Commonly caught by coastal fisheries in Taiwan, but apparently not as abundant as C. plagiosum . Historical records of C. griseum from Taiwan are likely misidentifications of this species. A recent molecular study has shown this species probably belongs to a species complex ( Naylor et al., 2012); taxonomic investigation is required to confirm the nomenclature of the western North Pacific populations.

Conservation status: Near Threatened.
