Description
Adults are recognised by the seven veins reaching the margin, the costa running around the entire margin, the absence of ocelli, and particularly by the short antennae which are no longer than the head. Larvae resemble larval ''Lutzomyia'' (Biology
Adult Thaumaleidae are encountered infrequently, usually close to the hygropetric aquatic larval habitat. The undersides of bridges over smaller running waters are common adult gathering sites. Thaumaleid larvae are usually hygropetric in vertical, thin water films alongside waterfalls and torrents. They prefer low temperatures and are most frequent in fully shaded localities. They feed by grazing onName
The dipteran family name Orphnephilidae Rondani, 1847, based on ''Orphnephila'' Haliday, 1832, was used until Bezzi (1913) synonymized ''Orphnephila'' with ''Thaumalea'' Ruthe, 1831 and adopted Thaumaleidae, based on the senior synonym ''Thaumalea''. This family name has been almost universally used since that time and it is to be maintained. Had Thaumaleidae not come into prevailing usage, Orphnephilidae would continue in use despite the fact that ''Orphnephila'' is a junior synonym. Thaumaleidae is cited with its own author and date, followed by the date of the replaced name in parentheses: Thaumaleidae Bezzi, 1913 (1847). It takes precedence over Orphnephilidae Rondani, 1847, and any subsequently published synonyms.References
