4A479569FFA0FF9B1CEBFAFEFE8F6967.taxon	distribution	The Ceratomerinae are confined to the Southern Hemisphere, recorded from New Zealand, Australia, Norfolk Island, southern South America (Argentina and Chile) and high-altitude habitats in Peru, Ecuador and Bolivia (Sinclair 2017 b).	en	González, Christian R., Elgueta, Mario, Rafael, José Albertino (2021): A catalog of the Brachystomatidae of Chile (Diptera: Empidoidea). Zootaxa 4969 (1): 149-165, DOI: https://doi.org/10.11646/zootaxa.4969.1.8
4A479569FFA0FF991CEBF9BAFE826EE4.taxon	discussion	Remarks. Ceratomerus includes 13 species currently known from South America (Sinclair 2010) with seven of them known from Chile, and has representatives in Australia (19 species distributed along Eastern territories, including Tasmania) (Evenhuis 2017) and New Zealand with the majority of species (45 species, Sinclair 2017 b). An identification key to species of Ceratomerus in South America was provided by Sinclair (2010). Tomia Paramonov was erected for the highly autapomorphic species Ceratomerus campbelli Paramonov, but the extreme morphological features are not unusual for the genus Ceratomerus, and Colless & McAlpine (1991) were justified in this synonymy (Sinclair 2003). Tomia Paramonov is a junior homonym of Tomia Martynov, 1936, a fossil Paraplecopteran of the family Tomiidae.	en	González, Christian R., Elgueta, Mario, Rafael, José Albertino (2021): A catalog of the Brachystomatidae of Chile (Diptera: Empidoidea).

4A479569FFA2FF991CEBFC6DFB83692C.taxon	discussion	Remarks. Sinclair (2010: 205) cited three specimens of this species from “ Pata de Gallina ”, collected “ 10 - 25. i. 1993 ”, locating this point in Atacama Region in the desert area of Chile, a record we consider as erroneous, as there are some localities with this name at different latitudes in Chile. To be accurate we need to consider the collection data given for one female of C. paraconnexus by Sinclair (2010: 214), collected at “ S. Concepcion, Laraquete, 10 - 25. i. 1993, P. Salinas ”; the identical collection date leads us to associate the collection locality of Pata de Gallina to Arauco Province (exactly S of Contulmo), for its vicinity to Laraquete, more than in homonymous localities in Biobío (SW Los Angeles) or Concepción (6 km S Concepcion, urban area) provinces.	en	González, Christian R., Elgueta, Mario, Rafael, José Albertino (2021): A catalog of the Brachystomatidae of Chile (Diptera: Empidoidea).

4A479569FFA4FF9F1CEBFD15FF336A68.taxon	discussion	Remarks. Apalocnemis is a genus with 28 worldwide described species, occurring mainly in the Australasian and Neotropical Regions (Sinclair 2017 a), the latter region now split into Andean and Neotropical regions by Morrone (1999, 2001). The New World distribution extends from southwestern New Mexico (USA) (B. J. Sinclair pers. comm. 2021) through Central America (Cumming & Sinclair 2009) to the extreme south of Argentina and Chile (Rafael & Sinclair 2012). An identification key to species of Apalocnemis in South America was provided by Collin (1933).	en	González, Christian R., Elgueta, Mario, Rafael, José Albertino (2021): A catalog of the Brachystomatidae of Chile (Diptera: Empidoidea).

4A479569FFA9FF931CEBF952FAA06D89.taxon	discussion	Remarks. Both species were described on the same page by Philippi (1865) and H. melanogaster was described before H. ambiguus. Both were synonymized with a question mark “? ” by Collin (1933) and this nomenclatural act was followed by subsequent authors (Smith, 1967; Yang et al., 2007) with no comments. This dubious synonymy never was checked, nor confirmed and here we are maintaining the synonymies as considered by Collin (1933).	en	González, Christian R., Elgueta, Mario, Rafael, José Albertino (2021): A catalog of the Brachystomatidae of Chile (Diptera: Empidoidea).

4A479569FFADFF971CEBF900FC1C6FB0.taxon	discussion	Remarks. Hyperperacera was described based on one species from southern Chile, characterized by vein R 4 + 5 simple and arista placed slightly before the end of the very small postpedicel. According to Sinclair & Cumming (2007, p. 37), it is mostly likely congeneric with Heterophlebus Philippi.	en	González, Christian R., Elgueta, Mario, Rafael, José Albertino (2021): A catalog of the Brachystomatidae of Chile (Diptera: Empidoidea).
