Dorsal fins with extensions of dark body saddles above base, narrow whitish posterior margins, remaining fin pale grey. Anal fin mostly grey with a narrow (sometimes indistinct) blackish anterior margin, posterior margin whitish. Pectoral fins with a strikingly distinct, narrow black anterior margin (Fig. 2) and a narrow whitish posterior margin; fins darker dorsally than ventrally.

Named for Dr Shannon Corrigan whose extensive molecular population and phylogenetic work on sharks has contributed toward an improved understanding of their alpha taxonomy and phylogenetic relationships. Molecular analysis. The analysis of the NADH 2 data (Fig. 4) suggest that Galeus corriganae represents a monophyletic lineage that is distinct from, but most closely related to Galeus priapus Séret & Last, 2008 from New Caledonia. These two species are, in turn, sister to G. nipponensis Nakaya, 1975, G. longirostris Tachikawa & Taniuchi, 1987 and G. eastmani (Jordan & Snyder, 1904) from the Northwest Pacific (Fig. 4). No tissue samples are available for Galeus gracilis Compagno & Stevens, 1993 from northwestern Australia, but this species likely belongs within this complex due to its morphological similarities to G. priapus and the new species. It should be noted that this inference is based on a single mitochondrial marker. Inclusion of multiple nuclear markers could affect the presented inference.	en	White, William T., Mana, Ralph R., Naylor, Gavin J. P.

03D1934EFFF0FFE7FF7D5BE4E64BFF06.taxon	description	Comparisons. Comparisons of the new species with its congeners is restricted to the two most similar species, G. priapus and G. gracilis, which are also the two closest congeners from a geographical sense. Galeus corriganae sp. nov. is almost identical in appearance to Galeus priapus from New Caledonia but differs from this species in the following characters: broader head (head width 10.4 – 13.2 vs. 8.3 – 9.9 % TL in G. priapus; interorbital width 7.2 – 7.8 vs. 6.0 – 7.0 % TL), larger eyes (orbit length 4.0 – 4.6 vs. 2.6 – 3.5 % TL), longer upper labial furrows (2.2 – 2.9 vs. 1.4 – 2.1 % TL), slightly larger nostrils (nostril width 25 – 3.0 vs. 2.2 – 2.3 % TL), pelvic and anal fins further apart (pelvic – anal space 12.2 – 13.0 vs. 10.0 – 11.7 % TL), shorter pelvic-fin base (base length 6.3 – 7.2 vs. 7.6 – 9.3 % TL) and longer pelvic-fin inner margin (4.2 – 4.7 vs. 2.8 – 4.2 % TL), shorter anal-fin inner margin (2.0 – 2.5 vs. 1.3 – 1.9 % TL) Galeus corriganae sp. nov. is also similar to Galeus gracilis from northwestern Australia but differs in the following characters: more vertebrae (monospondylous centra 38 – 39 vs. 33 – 36 in G. gracilis; precaudal centra 83 – 86 vs. 74 – 78; total centra 130 – 134 vs. 135 – 141), smaller anal fin (posterior margin length 5.2 – 6.3 vs. 6.4 – 7.3 % TL), pelvic – anal space much longer (12.2 – 13.0 vs. 8.0 – 10.3 % TL), claspers of adults likely to be much longer (outer length of adolescent male 8.4 vs. 5.2 – 7.3 % TL in adult males of G. gracilis).	en	White, William T., Mana, Ralph R., Naylor, Gavin J.
