New Data on Larvae of Weevils of the Genus Lixus (Coleoptera, Curculionidae) from Central Asia

摘要

Larvae are described for the first time for three species of the genus Lixus (L. bifasciatus, L. rubicun-dus, and L. subulatus). The larvae dwell in stalks of herbaceous plants. The larvae differ in the structure of the en-docarina and prelabium and the chaetotaxy of the head and epipharynx. Analysis of larvae of the new and already described species of this genus has shown that the larva of L. bifasciatus shares some characters with the larvae of L. astrachanicus, and L. rubicundus, and the larva of L. subulatus, with that of L. bescrensis.
