Germainiellus Morrone, 1993 Fig. 32

Germainiellus Morrone, 1993a: 125.

Type species.

Listroderes dentipennis Germain, 1895 (by original designation).

Diagnosis.

Small to medium-sized (6.0-8.4 mm); vestiture of seta-like scales and setae; pronotum transverse; postocular lobes present.

Relationships.

Germainiellus is closely related to Antarctobius , Listroderes and the clade Methypora-Rupanius-Acrorius-Trachodema-Lamiarhinus-Philippius. It was originally described as intermediate between Antarctobius and Listroderes (Morrone, 1993a). 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.

Germainiellus angulipennis (Germain, 1895); Germainiellus attenuatus (Germain, 1895); Germainiellus dentipennis (Germain, 1895); Germainiellus fulvicornis (Germain, 1895); Germainiellus laevirostris (Germain, 1895); Germainiellus lugens (Germain, 1895); Germainiellus ovatus (Boheman, 1842); Germainiellus philippii (Germain, 1896); Germainiellus planipennis (Blanchard, 1851); Germainiellus punctiventris (Germain, 1895); Germainiellus rugipennis (Blanchard, 1851); Germainiellus salebrosus (Enderlein, 1907); Germainiellus spp. (MZFC).

Host plants.

Germainiellus dentipennis and Germainiellus fulvicornis : Nothofagus sp. ( Nothofagaceae ); Germainiellus laevirostris : Senecio smithii DC ( Asteraceae ); Germainiellus planipennis : Nothofagus dombeyi (Mirb.) Oerst. ( Nothofagaceae ) and Peumus boldus Mol. ( Monimiaceae ); Germainiellus salebrosus : Empetrum rubrum Vahl ex Willd. ( Empetraceae ) (Morrone, 1993a).
