Maruina

Distinguished from other Psychodidae genera by aquatic larval and pupal stages adapted for flowing water. The genus can be separated into two subgenera: Aculcina and Maruina, based on morphological characters (specific diagnostic features for subgenera require examination of type specimens). Adults resemble typical small moth flies with hairy bodies and wings held roof-like over the body.

Flowing water environments; larvae and pupae are strictly aquatic and adapted for life in currents. Species recorded from Atlantic forest, Caatinga, and Amazonia biomes in Brazil.

Western Hemisphere, with majority of species in the Neotropical region. Documented from Brazil (eastern biomes of Atlantic forest and Caatinga, with recent records from Amazonia and Rio Grande do Sul), Colombia (Meta, Antioquia, Chocó, Cundinamarca departments), and elsewhere in the Neotropics.

Larvae and pupae are aquatic and adapted for life in flowing water; specific details of egg and adult stages not documented in available sources.

• Other Psychodidae generaMaruina is distinguished by its strictly aquatic larval and pupal stages adapted for flowing water, whereas most other Psychodidae have terrestrial or semi-aquatic larvae.
