Momoniidae

Stygomomonia sp., from Water Mites of North America.

Belongs within: Neohydrachnidia.

The Momoniidae are a group of more or less well-sclerotised, interstitial or hyporheic water mites whose larvae, where known, are parasites of Trichoptera. Members of the type genus Momonia are found in streams and lakes in southern Eurasia and North America (Walter et al. 2009).

Characters (from Walter et al. 2009): Adults with tibia I much longer than tarsus; claw of leg I flexing proximad to oppose dorsal surface of tarsus. Larva with idiosoma moderately flattened dorsoventrally; gnathosoma projecting beyond anterior edge of dorsal plate, entirely exposed in dorsal view; dorsal plate bearing four pairs of setae (verticils and scapulars), with setae c1 on lateral membranous integument; setae c2 and d2 thick and long relative to other hysterosomatic setae; excretory pore setae ps1 and ps2 absent, represented by their alveoli on excretory pore plate; legs with five movable segments; leg genua with setae Ge5 borne on tubercles; tibia I bearing eight setae (+2ϕ), including Ti11; leg tarsi lacking setae Tal4, bearing paired claws.
