FAMILY EPACTERISCIDAE FOSSHAGEN, 1973

Diagnosis: Female caudal rami usually of equal lengths (exceptions: Balinella longer on right; Gloinella longer on right); male caudal rami symmetrical or asymmet- rical, seta II spiniform, setiform, or apparently absent in Miheptneria , female seta VI tending to be asymmetrical, with one seta having one side bearing short setules, the other with long setules (exceptions Balinella , Cryptonectes , Oinella , Bunderia , Edaxiella , and Enantronoides ). Female antennule ancestral segment IV with aesthetasc (except for Oinella ). Mandible with exopod and basis forming major axis of palp; endopod poorly developed, two- or one-segmented, or absent, being at most half length of exopod segment 1, which when present, with at most two setae, segment 2 with four or fewer setae, except for Erebonectes and Miheptneria , which have seven and nine setae, respectively. Maxillule coxal epipodite with seta 9 absent (exception Miheptneria ), and tendency for further setae to be lost up to seta 6. Maxilla basis usually more than twice estimated length of coxa, basal endite with low profile, and endopod setae spine-like (exception Miheptneria , which has elongate basal endite and normal setae). Maxilliped endopod segments 2–6 shorter than length of coxa (not including praecoxa) and endopod setae spine-like (exceptions Miheptneria , Bomburiella , and Edaxiella , which appear to have normal setae on endopod). Leg 3 endopod segment 1 with outer distal corner bifid or trifid in clade 20. Male left leg 5 without inner process present on exopod segment 2 (only exception Balinella ) ( Table 7).
