Abstract

Third-instar larvae of Phyllophaga (s.str.) ilhuicaminai Morón and Phyllophaga (Listrochelus) cuicateca Morón and Aragón are described. Larvae of P. ilhuicaminai were taken only from the roots of Limonium sinuatum (L.) Miller (Plumbaginaceae), an ornamental herb growing in fields near Atlixco, Puebla, Mexico. Larvae of P. cuicateca were found only on roots of Amaranthus hypocondriacus L. (Amaranthaceae) in fields near Altepexi, Puebla, Mexico. These larvae cause damage to the root system of both plant species under culture. Illustrations of diagnostic structures, a brief discussion on the differences between these larvae and other Phyllophaga Harris larvae, and a key to the Mexican larvae of the genus are included.

Résumé

On trouvera ici la description des larves du troisième stade de deux espèces mexicaines, Phyllophaga (s.str.) ilhuicaminai Morón et Phyllophaga (Listrochelus) cuicateca Morón et Aragón, récoltés dans les environs d’Atlixco et Altepexi (Puebla, Mexique), respectivement. Les larves de P. ilhuicaminai été ont obtenues dans des cultures de Limonium sinuatum (L.) Miller (Plumbaginaceae), alors que celles de P. cuicateca été obtenues dans des cultures d’Amaranthus hypocondriacus L. (Amaranthaceae). Ces larves endommagent le système racinaire de ces cultures. Des illustrations des structures diagnostiques, une brève discussion sur les différences de ces larves avec celles d’autres larves du genre Phyllophaga Harris et une clé d’identification des larves mexicaines de ce genre sont inclus.
