The third instar larva of Anacaena cordobana Knisch, and the egg case of Anacaena lutescens (Stephens) are describedand illustrated. The taxonomic status of the immature stages of Anacaenini is clarified by comparing their morphology with thatdescribed in the literature. Larval descriptions of Anacaena and Paracymus published by Richmond (1920) are interchanged, as arethe identifications of all subsequent authors based on Richmond’s work. All Anacaenini genera for which larvae are known are diagnosed.A comparative morphological study of Anacaena larvae shows many similarities between Crenitis and Anacaena larvae, suggestinga close relationship between these two genera.
