An update on the knowledge and general understanding of the Chilean Diptera diversity.

Chilean flies play an important role in many aspects of phylogeny and evolution of Diptera given their uniqueness and direct link with the Gondwanan insect fauna. Many dipterists have considered the order to be one of the most diverse in Chile, but there are still many gaps of information to fill. This study updates the families, genera, and species known from Chile and addresses the evolutionary origin of most dipteran families-indicating which biogeographical layers they belong to.

The Neotropical tanyderid Araucoderus gloriosus (Alexander) (Diptera, Tanyderidae), with description of the egg, larva and pupa, redescription of adults, and notes on natural history.

Larvae, pupae and adults of Araucoderus gloriosus (Alexander) were collected during fieldwork in Chilean Patagonia, December 2013 and January 2014. Eggs were obtained from females that oviposited in captivity. Association of all life stages is based on co-occurrence and rearing of individual larvae to adults.

Redescription of Aposycorax chilensis (Tonnoir) (Diptera, Psychodidae, Sycoracinae) with the first identification of a blood meal host for the species.

Adults of Aposycorax chilensis were collected from several sites during fieldwork in Chilean Patagonia, December 2013. Specimens were swept or aspirated from roadside seeps and found in greatest numbers during the morning hours. DNA was extracted from a recently blood-fed female and was subjected to the polymerase chain reaction using vertebrate-specific 16S primers.
