Megninia sp., copyright Daktaridudu.
Belongs within: Analgoidea.
The Analgidae are a group of mites inhabiting the feathers of a variety of birds, most commonly Passeriformes. Infestations by species of Megninia have been known to cause declines in weight and egg production among domestic poultry (OConnor 2009).
Characters (from OConnor 2009): Chelicerae well developed; legs III and IV inserted laterally or ventrally; genu III with solenidion ς present; tibia IV with one ventral seta; tarsus I with solenidion ω1 inserted basally; pretarsal ambulacral stalk thickened, asymmetrical, with ventral surface convex, distally rounded at point of contact with ambulacral disc, arising ventrally from tarsal apex.
