Genus Demicryptochironomus Lenz, 1941

A genus of 31 described species distributed in all zoogeographical regions, except Oceania and Antarctica. Larvae assigned to Demicryptochironomus have been recorded from Brazil (Roque et al. 2004; Trivinho-Strixino 2011). A key to adult males was given by Yan et al. (2008). The larvae occur in sandy or muddy sediments in lakes, streams, and rivers, where they have been reported to be predatory, especially on oligochaetes (Epler et al. 2013).
