Catalogue of Pyrgotidae (Diptera: Tephritoidea) from Chile

A catalogue of the Pyrgotidae (Diptera) from Chile is provided. All valid names are presented, comprising three species in two genera for the country. All references known to us from the taxonomic and biological literature, to the included names, are provided, including information about name, author, year of publication, page number, type species, type locality, distribution, and references.

The family is divided into the subfamilies Pyrgotinae and Teretrurinae (McAlpine, 1990). Pyrgotinae, the most specious subfamily, has a worldwide distribution and is composed by the tribes Prodalmanniini, Pyrgotini, Toxopyrgotini, and Toxurini (Korneyev, 2016). Teretrurinae, composed by 11 species in five genera, has a distribution restricted to South America and Oceania. The South American fauna of Teretrurinae is composed by the genera Pyrgotosoma Malloch and Teretrura Bigot.
The immature stages of Pyrgotinae are internal abdominal parasites of adult Scarabaeidae (Coleoptera), and the adults are nocturnal (Mello, 2017). The only known biological record for a South American pyrgotid was presented by Mello et al. (2010) for the species Carreapyrgota bernardii Mello, Lamas & Rafael, 2010 flying in association with the scarab beetle Pelidnota sordida (Germar, 1824). The South American Teretrurinae are also likely to be nocturnal, given their often being collected in light traps as indicated on their specimens labels.
The Neotropical fauna of Pyrgotidae was catalogued by Stuardo (1946, as Otitidae), and Steyskal (1967), including the Chilean species. Studies of the species from southern South America are scarce (Malloch, 1933). The aim of this paper is to provide an updated catalogue of species of Chile with details of the taxonomic records.

MATERIAL AND METHODS
Distributions are cited for each species based on published records and new records of specimens in the collection of Museo Nacional de Historia Natural de Chile and from the database of specimens in the Canadian National Collection. Chilean distribution is presented by region (from north to south), province (from north to south) and locality (arranged alphabetically). Since there are important vegetation and orographic differences in each province of the country, details of each collection record are provided. This catalogue follows the generic classification of Aczél (1956a, b).

DISCUSSION
The diversity of Pyrgotidae in Chile is low compared with other countries of South America (Steyskal, 1967;Mello, 2014). Finally, in this catalogue we recognize three species of Pyrgotidae in two genera and one subfamily for Chile. The genus Teretrura Bigot is the most species-richest with two species.
