A checklist of Branchiopoda (Anostraca and Cladocera) of Chilean continental waters Author Escalante, Patricio De Los Rios Author Kotov, Alexey A. text Zootaxa 2015 4027 3 366 388 journal article 10.11646/zootaxa.4027.3.3 ff712a43-2153-4efc-9fb3-65b8b02b2927 1175-5326 231749 86633D28-9928-4719-AD86-CB9664E98AF8 Family Macrothricidae Norman & Brady, 1867 sensu Smirnov, 1992 (42) Cactus cactus ( Vávra, 1900 ) (described as Macrothrix cactus Vávra, 1900 ). Punta Arenas ( 53° 09' S ; 70° 55' W ) ( Vávra 1900 ; Ruiz & Bahamonde 1989 ); Lago San Ricardo, Tierra del Fuego ( Smirnov & Kotov 2009 ). Listed for Chile by Villalobos (2006) . This taxon is an endemic of the southernmost corner of South America and Tierra del Fuego. (43) Macrothrix atahualpa Brehm, 1936 (syn. M. palearis Harding, 1955 , syn. Echinisca palearis ). Chungará lake ( 18°15' S ; 69°10' W ) (Domínguez 1983; Ruiz & Bahamonde 1989 ; Berrios & Sielfeld 2000 ), Salar de Lagunillas ( 19°59' S ; 68° 54' W ) (Kotov et al. 2010). Listed for Chile by Villalobos (2006) . Macrothrix ciliata Vávra, 1900 . Junior synonym of M. oviformis ( Kotov 2007 ) . Macrothrix chevreuxi Guerne & Richard, 1892 . Peña Blanca, Quilpué ( 33° 07' S ; 71° 14' W ), Valdivia ( 39° 49' S ; 73° 15' W ) ( Ekman 1900 ). It is regarded as junior synonym of M. triserialis ( Smirnov 1992 ) . Even if M. chevreuxi will be regarded as a valid taxon in the future, a chance to find this African taxon in South America is minimal keeping in mind already demonstrated non-cosmopolitanism of this group ( Dumont et al. 2002 ). (44) Macrothrix goeldi Richard, 1897 . "près de Concepción et à Lunache” (= Limache, 32° 59' S ; 71° 17' W )" ( Richard 1897 ; Kotov & Ferrari 2010). A preliminary name for Macrothrix cf. spinosa King, 1853 from South America . But this group needs to be accurately revised worldwide. (45) Macrothrix hirsuticornis Norman and Brady, 1867 . Manzanillo river ( 33° 26' S ; 70° 28' S ) ( Brehm 1936 ); Plateado reservoir ( 33° 04' S ; 71° 39' W ), Yeso reservoir ( 33° 39' S ; 70° 07' W ) ( Domínguez & Zúñiga 1976 ; Ruiz & Bahamonde 1989 ); Santiago, Antarctic Peninsula ( Berrios & Sielfeld 2000 ). Listed for Chile by Villalobos (2006) . In reality, this determination is problematic. No M. hirsuticornis s.st. is present in southern portion of South America , only M. oviformis ( Kotov 2007 ) . But more northern populations need to be revised. Macrothrix inflata Daday, 1902 . Junior synonym of M. oviformis . (46) Macrothrix laticornis (Jurine, 1820) s. lat. (described as Monoculus laticornis Jurine, 1820 ). El Peral ( 33° 30' S ; 71° 35' W ) ( Araya & Zúñiga 1985 ); Valparaiso ( 33° 04' S ; 71° 38' W ) ( Berrios & Sielfeld 2000 ). Listed for Chile by Villalobos (2006) . A widely distributed group needs to be revised worldwide keeping in mind that even in Holarctic it is represented by several species ( Silva-Briano et al. 1999 ). M. odontocephala Daday, 1902 . Junior synonym of M. oviformis . (47) Macrothrix oviformis Ekman, 1900 (syn. M. ciliata Vávra, 1900 ; M. inflata Daday, 1902 ; M. odontocephala Daday, 1902 . Del Inca lagoon ( 32° 49' S ; 70° 09' W ), Peñuelas lagoon ( 33° 09' S ; 71° 32' W ) ( Araya & Zúñiga 1985 ; Ruiz & Bahamonde 1989 ; Berrios & Sielfeld, 2000 ), Laguna Melliza, Parque Nacional de las Torres del Paine ( 51° 03' S ; 72° 57' W ); grassy meadow, 8 km north of turnoff to Monte Aymond ( 52° 08' S ; 69° 31' W ) ( Kotov 2007 ); Salar de Lagunillas ( 19° 59' S ; 68° 54' W ) (Kotov et al. 2010). Listed for Chile by Villalobos (2006) . A taxon widely distributed in southernmost portion of South America , Tierra del Fuego, Antarctic Peninsula and surrounding islands ( Kotov 2007 ). Macrothrix palearis Harding, 1955 . Junior synonym of M. atahualpa . (48) Macrothrix triserialis Brady, 1886 s.lat. Реñаblаnса close to Quilpué ( 33° 07' S ; 71° 14' W ); Valdivia ( 39° 49' S ; 73° 15' W ) ( Vávra 1900 ; Ruiz & Bahamonde 1989 )."Valparaiso ( 33° 04' S ; 71° 38' W ) a Valdivia" ( Berrios & Sielfeld 2000 ). Most probably, these populations belong to M. elegans Sars, 1901 , common in South America ( Dumont et al. 2002 ; Kotov et al. 2004 ). (49) Streblocerus serricaudatus (Fischer, 1849) . Isla Margarita ( Löffler 1961 ); Lago Llanquihue ( 41° 15' S ; 73° 01' W ) ( Thomasson 1963 ); Lago Todos los Santos ( Zúñiga & Domínguez 1977 ; Ruiz & Bahamonde 1989 ); Former Lakes district (current River and Lakes districts: 39° 48' S – 45° 48' W ) ( Berrios & Sielfeld 2000 ). Listed for Chile by Villalobos (2006) . S. cf. serricaudatus from South America is very similar to those from Eurasia ( Paggi 1976 ; Smirnov 1992 ), but this taxon must be revised according to new standards of morphological analysis.
