Family Ilyocryptidae Smirnov, 1976 sensu Smrnov, 1992

(36) Ilyocryptus brevidentatus Ekman, 1905 . Unnamed chanel, 105 km N of Punta Arenas (53° 09' S; 70° 55' W) (Kotov et al. 2002). Endemic of southern South America (Kotov & Štitfer 2006).

(37) Ilyocryptus denticulatus denticulatus Delachaux, 1919 (described as Ilyocryptus sordidus var denticulatus Delachaux, 1919). Chungará lake (18° 15' S; 69° 10' W); a small stream, Parinacota Region (18° 10' S; 69° 15' W) (Kotov & Štifter 2005; Kotov et al. 2010). It seems to be an endemic of the Andean highlands (Kotov & Štifter 2006).

(38) Ilyocryptus denticulatus freyi Kotov et Štitfer, 2005 . Shallow channel in grossy meadow, N of turnoff to Monte Aymond (52º 10' N; 69º 30' W) (Kotov & Štifter 2005). Probably an endemic of southernmost portion of South America (Kotov & Štifter 2006).

Ilyocryptus longiremis Sars, 1888 . Valdivia (39° 49' S; 73° 15' W) (Ekman 1900). Junior synonym of I. spinifer (Kotov & Dumont 2000) .

(39) Ilyocryptus cf. nevadensis Cervantes-Martínez, Gutiérrez-Aguirre & Elías-Gutiérrez, 2000 . A small stream, Parinacota Region (18° 10' S; 69° 15' W) (Kotov et al. 2010). An Andean finding needs to be re-checked based on more ample material.

(41) Ilyocryptus spinifer Herrick, 1882 (syn. Ilyocryptus halyi Brady, 1886, I. longiremis Sars, 1888, Acanthocercus immundus Ihering, 1895, I. verrucosus Daday, 1905, I. tetraspinus Bergamin, 1939): Isla Margarita (41° 46' S; 73° 15' W), Bonita lagoon (40° 53' S; 72° 52' W), Llanquihue lake (41° 07' S; 72° 50' W), Todos los Santos lake (41° 06' S; 72° 15' W) (Löffler 1961; Zúñiga & Domínguez 1977); Peñuelas lagoon (33° 09' S; 71° 32' W), Orozco reservoir (33° 14' S; 71° 25' W) (Araya & Zúñiga 1985; Ruiz & Bahamonde 1989); "Valparaiso (33° 04' S; 71° 38' W) a Llanquihue (41° 15' S; 73° 01' W)" (Berrios & Sielfeld 2000). Listed for Chile by Villalobos (2006). To this moment it is regarded as a truly cosmopolitan taxon (Kotov & Dumont 2000).
