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).

Geographical distribution.
