Germainiellus  Morrone, 1993a: 125.

Type species.

Listroderes dentipennis  Germain, 1895 (by original designation).


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


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.
