Description
Summary:Zelandobius edensis n. sp. is described from a spring-fed creek in the headwaters of the Rangitata River catchment, South Canterbury, New Zealand. Adult males exhibit varying degrees of brachyptery and the only female collected also had short wings. Larvae are easily identified by their covering of long translucent hairs not found in other members of the Zelandobius confusus-group. The link between adult and nymph was confirmed by comparing 600-base-pair sequences of the mitochondrial gene, cytochrome c oxidase 1. Observations suggest the life cycle may be strongly synchronised by temperature constraints on nymphal growth and development, and/or a short season suitable for feeding and reproduction by the terrestrial adults.
