Review of Chilean Cyrtinae (Diptera: Acroceridae) with the Description of Three New Species and the First Record of from Argentina.

Acrocerid flies are endoparasitoids of spiders that are distributed in all ecosystems except deserts and the poles. This group was historically classified into three subfamilies. However, molecular analyses have indicated two new subfamilies.

Updating the knowledge of the flower flies (Diptera: Syrphidae) from Chile: Illustrated catalog, extinction risk and biological notes.

Syrphidae, more commonly known as flower flies, are considered one of the most important Diptera families worldwide because of their critical role in pollination, biological control and decomposition of organic matter. The study of these flies in Chile has stagnated due to a lack of local experts as well as the absence of an updated catalog of species. This study is an attempt to remedy the latter of these issues by providing an illustrated and updated catalog to the Syrphidae of Chile.

A new spider fly (Diptera: Acroceridae: Ogcodinae: Ogcodes Latreille) from Chiloé Island's evergreen forest and new distributional records for other spider flies in Chile.

Ogcodes Latreille is the largest genus of Acroceridae. They exhibit a cosmopolitan distribution and parasitize several spider families. Eleven Neotropical species are currently recognized in the genus, with five of them occurring in Chile, though distribution data is limited in this group of rarely collected flies.
