Antarctobius Fairmaire, 1885 Fig. 31

Antarctobius Fairmaire, 1885: 58.

Type species.

Antarctobius lacunosus Fairmaire, 1885 (subsequent designation by Morrone, 1992a).

Diagnosis.

Small to medium-sized (3.7-9.5 mm); vestiture of seta-like or subcircular scales and setae; pronotum subcircular; postocular lobes absent.

Relationships.

Antarctobius is closely related to Germainiellus, Listroderes and the clade Methypora-Rupanius-Acrorius-Trachodema-Lamiarhinus-Philippius. The distinction between Antarctobius , Germainiellus and Listroderes is not without doubt (see Morrone and Marvaldi, 1998), and future analyses may determine if they are merged into a single genus.

Species included.

Antarctobius abditus (Enderlein, 1907); Antarctobius bidentatus (Champion, 1918); Antarctobius falklandicus (Enderlein, 1907); Antarctobius germaini (Kolbe, 1907); Antarctobius hyadesii Fairmaire, 1885; Antarctobius lacunosus Fairmaire, 1885; Antarctobius malvinensis Posadas and Morrone, 2004; Antarctobius rugirostris Champion, 1918; Antarctobius vulsus (Enderlein, 1907); Antarctobius yefacel Morrone, 1992.

Host plants.

Antarctobius abditus : Senecio candidans DC ( Asteraceae ); Antarctobius hyadesii : Senecio alloeophyllus O. Hoffm. and Senecio candidans DC ( Asteraceae ) (Morrone, 1992a; Marvaldi, 1998).

Immature stages.

Antarctobius abditus and Antarctobius falklandicus (Marvaldi, 1998).

Geographical distribution.

Andean region (Subantarctic subregion), in southern Chile and southern Argentina , including the Falkland Islands (Islas Malvinas) ( Morrone 1992a; Posadas and Morrone 2004; Posadas 2008, 2012).

Material examined.

Antarctobius abditus (BMNH), Antarctobius bidentatus (BMNH), Antarctobius falklandicus (AMPC, BMNH, MZFC), Antarctobius germaini (AMNH, BMNH, CADIC, CMNC, CWOB, IPUM, MHNS, MLP, MZFC), Antarctobius hyadesii (BPBM, CMNC, MHNS, MZFC), Antarctobius lacunosus (BMNH, MCZ, MHNS), Antarctobius rugirostris (BMNH), Antarctobius vulsus (BMNH, USNM) and Antarctobius yefacel (AMNH).
