DNA barcodes provide insights into the diversity and biogeography of the non-biting midge (Diptera, Chironomidae) in South America.

South America, particularly within its tropical belt, is renowned for its unparalleled high levels of species richness, surpassing other major biomes. Certain neotropical areas harbor fragmented knowledge of insect diversity and face imminent threats from biodiversity loss and climate change. Hence, there is an urgent need for rapid estimation methods to complement slower traditional taxonomic approaches.

A new species of Parasycorax and new records of Sycorax (Diptera: Psychodidae, Sycoracinae) from southern Brazil.

Sycoracinae is a subfamily of Psychodidae, currently with 45 extant species (Curler Jacobson 2012; Santos et al. 2013) classified in three genera: Sycorax Haliday in Curtis; Parasycorax Duckhouse and Aposycorax Duckhouse (Duckhouse 1972; Young 1979). Sycorax comprises a majority of this diversity with 40 extant species, 15 of which are recorded from the Neotropical region (Curler Jacobson 2012; Santos et al.

Some notes on taxonomy and distribution of Neotropical Aedokritus Roback and Axarus Roback (Diptera: Chironomidae: Chironominae).

Hematophagous Flies Attracted to Frog Calls in a Preserved Seasonal Forest of the Austral Neotropics, with a Description of a New Species of Corethrella (Diptera: Corethrellidae).

The signaler-eavesdropper interaction has been investigated for a wide range of organisms, and although many flies feed on calling frogs, this dynamic has been addressed only poorly in the austral Neotropics. We investigated this interaction in southern Brazil using pairs of suction traps (acoustic + silent) broadcasting frog calls or an artificial white noise in ponds and streams. From 139 sessions, flies of the genera Corethrella (Corethrellidae), Forcipomyia (Ceratopogonidae) and Uranotaenia (Culicidae) were collected, including five Corethrella species, the most abundant of which was previously unknown and is formally described here.

FAMILY CHIRONOMIDAE.

Only 30 chironomid species distributed in 16 genera and three subfamilies are formally recorded to Colombia. Another 32 genera and two subfamilies have been recorded on larval stage, with no identification at species level. Many new records, genera and species are expected when focusing on systematics of chironomids from Colombia.
