Key to Neotropical Leptoceridae View in CoL genera (larvae)
There are 13 described genera of Leptoceridae ( Achoropsyche Holzenthal , Amazonatolica Holzenthal & Pes , Amphoropsyche Holzenthal , Atanatolica Mosely , Brachysetodes Schmid , Grumichella Müller , Hudsonema Mosely , Nectopsyche Müller , Neoathripsodes Holzenthal , Notalina Mosely , Oecetis McLachlan , Triaenodes McLachlan , and Triplectides Kolenati ) from the Neotropical region, but the larval stages of two monotypic genera, Achoropsyche duodecimpunctata (Navás) and Neoathripsodes anomalus Holzenthal , are still unknown and thus are not included in this key. Leptoceridae Genus A (cited and illustrated by Pes et al. 2005) is not considered in this paper. The simplified figures of the 11 known Neotropical genera, except Notalina , were modified from the original descriptions or keys to show the diagnostic characters.
