Acanthoxyla
Acanthoxyla is a genus of stick insects in the family Phasmatidae. All the individuals of the genus are female and reproduce asexually by parthenogenesis. However, a male Acanthoxyla inermis was recently discovered in the UK, probably the result of chromosome loss. The genus is the result of interspecific hybridisation resulting in some triploid lineages and some diploid lineages. The genus is endemic to New Zealand, but some species have been accidentally introduced elsewhere. The genus name Acanthoxyla translates from Greek as prickly stick.
