Head and otolith morphology of the genera Hymenocephalus, Hymenogadus and Spicomacrurus (Macrouridae), with the description of three new species Author Schwarzhans, Werner text Zootaxa 2014 2014-11-28 3888 1 1 73 journal article 10.11646/zootaxa.3888.1.1 1175-5326 10086415 1B437AE1-CF28-4C1B-95B6-C31A295905A0 Spicomacrurus dictyogadus Iwamoto, Shao & Ho, 2011 Figs. 3A–B , 5 Spicomacrurus dictyogadus Iwamoto, Shao & Ho, 2011: 518 ( type locality: 16°18’S , 167°46’E ). Discussion. The unique holotype of S. dictyogadus (MNHN 2009-1455) was visually inspected, but no otolith was extracted and no additional observations were made to the description of Iwamoto et al. (2011) , and the figure included is based on their detailed photographs. The species is remarkable for its blunter head profile with barely protruding, short and not spatulate nasal bones, characters which are considered plesiomorphic in respect to the other members of the genus.
