Abstract: | Abstract The adult male and female of Xenochironomus canterburyensis (Freeman) are redescribed, and the larva and pupa are described for the first time. The immature stages are obligate, inquiline commensals of the freshwater mussel Hyridella menziesi (Gray) inhabiting the littoral zone of some New Zealand lakes. The labral setae of the larva are modified to form an elongate feeding brush, and the pupa lacks a posterolateral spur on the eighth abdominal segment. X. canterburyensis appears to be closer to X. xenolabis in certain synapomorphic features and in that both are closely associated with a host species. |
