Tribe Anisomysini Wittmann, Ariani & Lagardère, 2014

Diagnosis

The diagnosis of this tribe is slightly modified from Wittmann et al. (2014) due to certain spine-like cuticle structures of the telson being now interpreted as laminae (see ‘Methods’ and species descriptions below):

Antennal scale setose all around (exceptionally with blunt spine on outer margin) and with short apical segment; carpopropodus of thoracic endopod 6 with 1–3 segments; two pairs of well-developed oostegites, rudimentary oostegite on thoracic endopod 6; pleopods rudimentary in both sexes, except male pleopod 4 and to a minor extent also pleopod 3; third male pleopod uniramous, unsegmented, mostly rudimentary as in females or reduced to small endopod fused with sympod; exopod of fourth male pleopod with total of 1–2 modified setae (1–2 on apical segment, 0–1 on subapical segment); uropods without spines; telson shorter than ultimate pleonite, terminally entire or with apical cleft, lateral margins bare or furnished with spines or laminae; spines (if present) on lateral margins arranged in continuous series, not arranged in groups of large spines with smaller spines in between; telson always devoid of setae.
