Subgenus Olivemysis Băcescu, 1968 Olivemysis Băcescu, 1968: 237 (defined in key). Olivaemysis – Băcescu 1970: 11–16 (incorrect subsequent spelling); 1981: 85 (evolution). —Hanamura & Kase 2001: 17 (expressed doubt on subgenus concept). Olivemysis – Bowman & Orsi 1992: 739 (definition in key). — Bravo & Murano 1996: 483 (in key). — Wittmann 2008: 368–370 (revalidated spelling, etymology). — Price & Heard 2011: 43–44 (first formal diagnosis). — San Vicente & Monniot 2014: 341 (taxonomy, in key). Type species Heteromysis ( Olivemysis ) rubrocincta Băcescu, 1968, by monotypy. 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. Key to species of the subgenus Olivemysis Băcescu, 1968 The subgeneric assignment is here explicitly indicated for all 39 acknowledged species of Olivemysis . An additional 13 species given below are insufficiently known and therefore so far not assigned to any subgenus. 1.

Type species Heteromysis ( Olivemysis ) rubrocincta Băcescu, 1968, by monotypy. 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. Key to species of the subgenus Olivemysis Băcescu, 1968 The subgeneric assignment is here explicitly indicated for all 39 acknowledged species of Olivemysis . An additional 13 species given below are insufficiently known and therefore so far not assigned to any subgenus. 1.
