0.6mm
in length,
0.5mm
in width. Major axis of embryo chambers in ephippium perpendicular to the dorsal (carapace) margin. General shape symmetrical, not skewed posteriorly. Well-developed posterior spine with thick basis. Identification unknown. From one locality on Easter
Island
, Terevaka, with
Ovalona
,
Sarscypridopsis
and
Paracyclops
. The record is here placed between brackets, because only one ephippium was found. Until confirmation (more specimens), this should be treated as a potential contamination of the original sample.
