General distribution. Canada, USA, Mexico, the Greater Antilles, the Lesser Antilles, Brazil, Peru, Argentina ( Drake & Hussey 1951; Moreira et al. 2011b).

Habitat. Microvelia hinei is found in a wide range of aquatic habitats. It is usually associated with emergent or floating vegetation and mats of Sphagnum L. moss in standing water (pools, ponds, lakes, swamps, sloughs, marshes, ditches and artificial reservoirs), in unshaded areas ( Wilson 1958; Polhemus & Chapman 1979; Bennett & Cook 1981; Vianna & Melo 2003; Pelli et al. 2006), but it has also been collected where vegetation was absent ( Wilson 1958) and in shaded areas ( Vianna & Melo 2003). It is also recorded from lotic habitats (creeks, streams and rivers) in standing water ( Wilson 1958; Bennett & Cook 1981; Pereira & Melo 2007), and brackish pools ( Wilson 1958).

At the INR, M. hinei was collected from margins with dense floating, emergent and submerged vegetation (mainly Pontederia azurea and Salvinia biloba ) and filamentous algae in lentic habitats (Galarza Lagoon, Luna Lagoon, Iberá Lagoon, Medina Lagoon, Itatí Lagoon, ponds, marshlands, ditches and flood-prone areas) and lotic habitats in standing water (Yacaré Stream, Carambola Stream, Corriente River, Pay Ubre Grande Stream, Pay Ubre Chico Stream and artificial channels), mostly in unshaded areas.

Remarks. Microvelia hinei is one of the most widespread species in the INR and the most common species of Microvelia in the Reserve. It was often collected together with M. mimula . The collection of this species from INR represents the first record from Corrientes Province. Microvelia hinei was recorded from Argentina without any mention of localities ( Coscarón 2017).
