Rangomaramidae View in CoL

This family comprises 20 Neotropical species distributed in six genera ( Amorim and Falaschi 2012). The Neotropical species fit in two of the four main rangomaramid subclades: the Chiletrichinae and the Ohakuneinae . The Chiletrichinae genus Chiletricha Chandler, 2002 is known from Chile, Argentina, and Chiletricha marginata (Edwards, 1940) from southern Brazil ( Amorim and Falaschi 2012); Eratomyia Amorim & Rindal, 2007 is known from Ecuador and Colombia. The Ohakuneinae genus Ohakunea Tonnoir & Edwards, 1927 is known in South America from southern Chile and Argentina, but there is an undescribed species of the genus known from southern Brazil (D.S. Amorim unpublished data); the genus Colonomyia Colless, 1963 has species known from Argentina and southern Chile, with C. brasiliana Amorim and Rindal, 2007 , known from the states of São Paulo ( Amorim and Falaschi 2012) and Mato Grosso (unpublished data); the genus Rogambara Jaschhof, 2005 is known from Costa Rica and Cabamofa Jaschhof, 2005 is known from Costa Rica and Panama ( Jaschhof 2004), but have not been recorded from Brazil.

The biology of rangomaramids remains largely unknown, and there is a lack of information regarding their immature stages ( Amorim and Falaschi 2012). The evolutionary relationships among rangomaramids are still a topic of discussion. The connection of the Rangomarama Jaschhof & Didham, 2002 , the Ohakuneinae , the Chiletrichinae and the Heterotrichinae in a clade was one of the most parsimonious solutions for the information available in Amorim and Rindal (2007), but a more extensive analysis of the relationships among Sciaroidea families is desirable. The monophyly of each of these four subfamilies of Rangomaramidae is well-founded.
