Abstract

Mature larvae of Gonioctena leprieuri (Pic) and Gonioctena aegrota (Fabricius) are described and illustrated for the first time, based on specimens collected on Genista spp. (Fabaceae) in Spain. A key to known larvae of subgenus Spartoxena Motschulsky is provided. Diagnostic characters for the identification of species within this subgenus are shape of labrum, arrangement of microtrichia of epipharynx, shape of tarsal claws, and numbers of tubercles on abdominal segments. Notes on distributions and host plants are provided.

Résumé

On trouvera ici la description, pour la première fois, des larves à maturité de Gonioctena leprieuri (Pic) et Gonioctena aegrota (Fabricius) à partir de spécimens récoltés sur Genista spp. (Fabaceae) en Espagne. Une clé permettra l'identification des larves connues du sous-genre Spartoxena Motschulsky. Les caractères diagnostiques qui permettent la séparation des espèces appartenant à ce sous-genre sont la forme du labre, la disposition des microtriches de l'épipharynx, la forme de l'ongle tarsal et le nombre de plaques sclérifiées aux segments abdominaux. Des renseignements sur les distributions et les plantes-hôte sont donnés.
