The Diamesinae (Diptera: Chironomidae) in High-Altitude Andean Streams Using Morphological and Molecular Approaches.

ABSTRACT: Diamesinae is one of the 11 subfamilies of Chironomidae, characterized by its preference for cold waters, typically found in mountainous regions. We aimed to study the biodiversity and distribution of two genera of this subfamily found in high-altitude streams in the Andes (Paraheptagyia Brundin, 1966 and Limaya Brundin, 1966), by combining morphological and molecular analyses. A database with 190 larval specimens of Diamesinae (160 of Paraheptagyia and 22 for Limaya), collected between July and October of 2011 from 20 streams in Colombia, Ecuador, and Peru, at altitudes above 2000 m a.s.l. was used. Paraheptagyia was found in the three countries, whereas Limaya was only found in Ecuador and Peru. Morphological analyses were based on 105 larvae mou
