First record of the genus Heterotrissocladius (Chironomidae: Orthocladiinae) from the Neotropical region

摘要

Here we report the occurrence of Heterotrissocladius (Diptera: Chironomidae: Orthocladiinae) for the first time in Central America, as well as in the Neotropical region. The report is based on sub-fossil chironomid head capsules from surface sediments of a high elevation lake, Lago Magdalena, Guatemala.
