Belongs within: Cytherocopina.
The Sphaeromicolinae are freshwater ostracods living as commensals on isopods of the families Sphaeromatidae and Cirolanidae. Members of the genus Sphaeromicola are found in Europe whereas Hobbsiella are found in Central and North America. The antennal segments are fused in Hobbsiella but remain distinct in Sphaeromicola.
Characters (from Hart & Hart 1974): Distal podomere of mandibular palp spatulate in shape; respiratory plate of maxilla lacking; masticatory lobes of maxilla vestigial. Peniferum shortened, usually with highly convex posterior margin.
