description
Species inventory A total of 39 species, including the new ones, is given in the key below. For 30 species see list in Price & Heard (2011). Nine species of this subgenus described after 2011 are H. cocoensis Price, Heard & Vargas, 2018; H. domusmaris Wittmann & Abed-Navandi, 2019; H. ekamako Wittmann & Chevaldonné, 2017; H. hornimani sp. nov.; H. ningaloo Daneliya, 2012; H. sabelliphila Wittmann & Wirtz, 2016; H. sixi sp. nov.; H. smithsoniana sp. nov. and H. waikikensis sp. nov. Definition Definition of subgenus modified after Price & Heard (2011), using present terminology, mainly in order to receive Heteromysis sixi sp. nov.: bifid flagellate spine, usually directed disto-mesially, and long, unbranched seta directed disto-laterally on disto-mesial edge of the antennular trunk; thoracic endopod 3 prehensile, moderately robust, some of the distal articles enlarged; disto-mesial edge of merus 3 not serrated, without tooth-like extension; propodus 3 mostly without paradactylary setae but, if any, representing small, simple setae; some of male pleopods 1 – 5 (in most species including pleopod 4), if any, modified by flagellate spines (or by attenuated setae); endopod of uropods shorter than exopod. Secondary diagnostic features are present in most species: eyestalks with disto-mesial process (tooth, tubercle), and male thoracic sternites with median processes. Morphological note Twelve out of a total of 35 previously known species here acknowledged as pertaining to this subgenus, have male pleopod 2 and additional pleopods modified. Male pleopod 2 is also modified in the four new species of Heteromysis, including two species with pleopod 2 modified also in females. These four species also share disto-mesial teeth on eyestalks and median processes on male thoracic sternites.
