Abstract

Larvae of the Australian fossorial carabid Carenum anthracinum Macleay are described from reared material and compared with the reared larva of C. elegans Macleay and eight different unassociated larval types belonging to the complex. These larvae exhibit an extraordinary range of character states indicating clearly that their placement in the tribe Scaritini cannot be retained. An examination of adult characters and, in particular, the fore tibial dentition confirms that Carenum and allied genera form a separate tribe, the Carenini, which appears to be a sister group of the remaining Scaritini (including Clivinina).

Résumé

Les larves du carabe fouisseur australien Carenum anthracinum Macleay sont décrites ici à partir de spécimens d’élevage et comparées à des larves d’élevage de C. elegans Macleay et à huit types larvaires différents non identifiés appartenant au même complexe. Ces larves ont une gamme extrêmement variée de caractères, ce qui indique clairement que leur classification dans la tribu des Scaritini ne peut être retenue. L’examen des caractères des adultes, en particulier la répartition des dents sur le tibia antérieur, confirme que Carenum et les genres qui lui sont apparentés constituent une tribu distincte, les Carenini, qui semble former un groupe soeur des autres Scaritini (y compris les Clivinina).
