Abstract

The larva of Anaquedius vernix (LeConte) is a typical quediine larva but has many distinctive morphological characteristics: tibial comb on the whole length of front tibia, not only on the apical part as in other quediine larvae; tubular organ of the third segment of the maxillary palp at the apex of the segment rather than at the base; pygopod and anal diverticula elongated and well developed, a condition probably related to the almost aquatic life habits of the larva.

Résumé

La larve d'Anaquedius vernix (LeConte) est une larve typique de Quediinae, mais elle possède néanmoins plusieurs traits morphologiques particuliers : grand développement du peigne tibial qui s'étend sur toute la longueur du tibia antérieur plutôt que sur sa partie apicale seulement comme chez les autres larves quédiines connues; organe tubulaire hyalin du troisième segment du palpe maxillaire porté à l'apex plutôt qu'à la base comme c'est habituellement le cas; grand développement du pygopode et des diverticules anaux relié probablement à la vie presque aquatique de la larve.
