Title: Characters of the larval head of Mycetina cruciata (Schaller) (Coleoptera: Endomychidae) and their phylogenetic implications

Abstract:

Head structures, especially internal features of the larva of Mycetina cruciataare described and discussed with respect to their functional and phylogenetic relevance. Spore masses are collected in the preoral chamber, mechanically treated by the mandibular molae, diluted with secretions, and sucked back by the unusually strong prepharyngeal and pharyngeal pumping apparatus. The presence of tube-like glands is a possible synapomorphy of all cucujiformsuperfamilies. Posterior tentorial arms which are shifted anteriorly and separated from the ten-torial bridge, thin and flattened dorsal tentorial arms, and reduced anterior arms are apomorphicfeatures shared by larvae of Mycetina, Coccinella, Glischrochilus, and cleroid larvae. The ori-gin of a strong bundle of M. tentoriostipitalis from the dorsal hypopharyngeal wall is another unusual derived character state shared by larvae of these taxa. Whether these structural affinities are due to a closer relationship between Endomychidae, Coccinellidae, Nitidulidae, and Cleroidea, or due to parallelism is a matter of further investigation. Presumably derived external features of the head are shared by several genera of Endomychidae. They suggest a closer relationship between Mycetina, Aphorista, Amphix, Epipocinae (excluding Periptyctus), and Bystus (Anamorphinae). Larval characters are in conflict with the monophyly of Lycoperdininae and Epipocinae.
