A catalogue of the Lonchaeidae (Diptera: Tephritoidea) and Teratomyzidae (Diptera: Opomyzoidea) of Chile

. A catalogue of the Lonchaeidae and Teratomyzidae of Chile is presented. This paper comprises two genera with five species of Lonchaeidae and two genera with two species of Teratomyzidae known from Chile, including information about the name of the taxon, author, year of publication, page number, type species, type depository, type locality, and references. The geographical distributions of each species were determined by examination of bibliographic data and of label data on specimens in collections.

Species of Lonchaeidae occur worldwide and are found in a wide range of habitats, from the Arctic Circle to the Equator and in all zoogeographical regions (MacGowan & Friedberg, 2008). Most lonchaeids are scavengers as larvae, breeding mainly in damaged plant tissues or decaying vegetation, but a few species are primary invaders of living plants (Norrbom & Korytkowski, 2010).
Members of Lonchaeidae can be recognised by the following characters: moderately small (body length 3.0-6.0 mm), relatively setose, shiny black to metallic blue or green, with wings usually hyaline. Body stout, abdomen broad and flat. Face broad, usually without strong carina. Eye large, pilose or bare. Without vibrissa but one or more sub vibrissal vibrissae-like setae sometimes present. Wing with anal lobe and alula well developed, halter dark brown (Norrbom & Korytkowski, 2010;MacGowan & Rotheray, 2021).
Currently Teratomyzidae comprises seven genera and 24 species, distributed in the Australasian/ Oceanic, Oriental, and southern Neotropical regions. The systematic position of Teratomyzidae has been controversial. Courtney et al. (2017) and Pape et al. (2011) placed Teratomyzidae in the Opomyzoidea group, whereas Malloch (1933) placed the genera Teratomyza of Teratomyzidae in Anthomyzidae. D.K. McAlpine (1998) countered that teratomyzids further differ from the Anthomyzidae in the reduction of the prosternum and from the Opomyzidae in the presence of the vibrissae. More recently, Teratomyzidae has been placed in the Sphaeroceroidea, closely to Heleomyzidae and Paraleucopidae (Bayless et al., 2021;Bayless, 2022). Little known about the biology of Teratomyzidae. According to McAlpine & Keizer (1994), most teratomyzids were obtained by sweeping fronds of terrestrial ferns, usually in or near the margins of forests. D.K. McAlpine (1998) provided a diagnosis to Teratomyzidae: CuA₂+A₁ terminating well beyond the level of crossvein dm-cu, no elongate costal bristle overlapping the costal break, alula broad and produced distad of the alular incision, several fronto-orbital setae present, parafacial suture distinct, a large supra-alar seta present, no abdominal sternite 6 in the male, and a distinctively modified postabdomen in the female.
The goal of this paper is to provide a catalogue of the Lonchaeidae of Chile and an updated cata-logue to the Teratomyzidae of Chile with references and additional information for each species, and genus of both families.

MATERIAL AND METHODS
For each species, the Chilean distribution is given by region and province (from north to south) and localities (alphabetically) when such data are available from the literature and from specimens in collections.

RESULTS
Two genera with five species of Lonchaeidae and two genera with two species of Teratomyzidae have been recorded from Chile (Table 1).
