It is a common bycatch in demersal trawl and longline fisheries in central and southern Chile (Concha et al. 2010). The species is plain dark brown or blackish above and below, has distinct labial furrows, with lowers noticeably longer than uppers, an anal-fin base length less than 1.5 times second dorsal-fin base length, matures at 52 – 59 cm TL and reaches a maximum size of 73 cm TL. The second species reported from the southeastern Pacific Ocean is B. giddingsi McCosker, Long & Baldwin, 2012, which may be endemic to the Galapagos Islands (McCosker et al. 2012). It is distinguishable from all congeners by having very few tooth rows per jaw (20 – 26 vs. 53 – 111) and its striking coloration: chocolate brown dorsally with pale spots, the largest being about equal in size to eye diameter above midline, smaller below; posterior margin of dorsal, pectoral, and pelvic fins pale; ventral surface pale. Additionally, it has a dorsal caudal-fin margin with prominent crest of comb-like dermal denticles. From the western Pacific Ocean, two species have been recorded, B. dawsoni and B. immaculatus (Chu & Meng, 1982). Bythaelurus dawsoni is apparently endemic to the waters around New Zealand (Francis 2006). It is light brown to gray on dorsal and lateral surfaces with a line of white spots on sides of small individuals and whitish ventrally, has fin tips with broad white areas and dark bands on the caudal fin. The labial furrows are distinct, with lowers noticeably longer than uppers, the anal-fin base length is less than 1.5 times second dorsal-fin base length, the size at maturity is 32 – 38 cm TL and the maximum size is 42 cm TL. Bythaelurus immaculatus is known only from the three type specimens, caught in the South China Sea (White & Last 2013). This species has a plain dark yellowish brown coloration, reduced labial furrows, with uppers and lowers about equal in length, an anal-fin base length less than 1.5 times second dorsal-fin base length, a prevent length 1.3 times in tail length, a preorbital snout length subequal to eye length, a length of lateral trunk denticles less than twice their width and reaches a maximum size of 76 cm TL (White & Last 2013), representing the largest known species of Bythaelurus (Weigmann 2016). For the eastern Indian Ocean, two species have been reported: B. incanus Last & Stevens, 2008 and B. hispidus. Bythaelurus incanus is known only from the holotype, a juvenile male collected off the Ashmore Terrace		1		Ebert & Concha & McCosker & Francis & White & Last								Peru	South	For	The	https://treatment.plazi.org/id/039987977D06FFA0FF2AF8F6FEF5F998#3B583CDC7D09FFA2FF7AFF00FD0DFBFC				MaterialCitation

Jawad, pers. comm., 2013), southern India (Nair & Appukuttan 1973; Nair & Lal Mohan 1973; Appukuttan & Nair 1988; Raje et al. 2002; Akhilesh et al. 2013), Andaman Islands (Alcock 1891; Springer & D’Aubrey 1972; Springer 1979; Séret 1987; Kaschner et al. 2015), and off Myanmar (T. Krajangdara & P. N. Psomadakis, pers. comm., 2015). This species has 5 – 6 indistinct, dark blotches on trunk and tail, an anal-fin base more than 1.5 times second dorsal-fin base length, rather slender (base width ~ 1.5 % TL) adult claspers with knob-like apex, a maturity size of 22 – 24 cm TL and a maximum size of 32 cm TL. In addition to B. hispidus, six further species of Bythaelurus are described from the western Indian Ocean, i. e. B. alcockii, B. bachi n. sp., B. clevai, B. lutarius, B. naylori and B. tenuicephalus. Bythaelurus alcockii was described from the Arabian Sea without exact locality data and is known only from the holotype, which has been lost (Compagno 1984 b; K. V. Akhilesh, pers. comm., 2014). For B. alcockii, a blackish coloration with hoary gray surface and some fins white-tipped posteriorly, as well as teeth with cusps and lateral cusps of subequal length were described (Alcock 1899). However, its validity is questionable (e. g. Springer 1979; Compagno 1984 b, 1988, 1999, 2005; Compagno et al. 2005; Last & Stevens 2008; Ebert et al. 2013; Kaschner et al. 2015; Weigmann 2016). It was originally described as Halaelurus alcockii and preliminarily placed in the subgenus Bythaelurus by Compagno (1988) but earlier Compagno (1984 b) had also stated that the species might instead belong to the genus Apristurus. As the only known specimen has been lost, it is currently impossible to resolve this issue. Bythaelurus bachi n. sp. is known only from the southern Madagascar Ridge		1		L.
