Henderson, R.C. 2011 . Diaspididae (Insecta: Hemiptera: Coccoidea), Fauna of New Zealand, No. 66 Lincoln Canterbury, New Zealand 275

Notes: The adult females of all 49 species of Diaspididae (Hemiptera: Coccoidea) known from New Zealand, except the tribe Leucaspidini, are described and illustrated. The 1st- and 2nd-instar nymphs of all the endemic species and of 4 Australian species that are of systematic interest are also described and illustrated. Four new genera, Anzaspis, Pellucidaspis, Pseudodonaspis, and Serenaspis and seven new species are described. Two genera, Fusilaspis and Symeria, are reinstated and redescribed. Hence there are twenty endemic species in ten genera and eight Australasian species in six genera. In addition, there are twenty-one cosmopolitan adventive species in fourteen genera. Nomenclatural changes are as follows: Chionaspis angusta Green and Pseudaulacaspis cordylinidis (Maskell) are transferred to Anzaspis n.gen.; Pseudaulacaspis phymatodidis (Maskell) is transferred back to an earlier combination as Fusilaspis phymatodidis (Maskell) and Pseudaulacaspis dubia (Maskell) is a new junior synonym of F. phymatodidis; Pseudaulacaspis epiphytidis (Maskell) becomes the senior synonym of Andaspis asteliae (Green) and is transferred to Pellucidaspis n.gen; Lepidosaphes lactea (Maskell) is transferred to Poliaspis Maskell and P. argentosis Brittin becomes a junior synonym of P. media Maskell; Natalaspis leptocarpi (Brittin) is confirmed as Poliaspoides leptocarpi (Brittin); Trullifiorinia minima (Maskell) becomes the senior synonym of Pinnaspis dysoxyli (Maskell) and is transferred to Serenaspis n.gen.; Scrupulaspis intermedia (Maskell) and Eulepidosaphes pyriformis (Maskell) are transferred to Symeria Green. In addition, Fiorinia drimydis (Maskell) is considered a nomen dubium because the only specimens available are 2nd-instar male nymphs of an unidentifiable Leucaspis species. Keys to allow separation of adult females of all genera and species are included. Earlier work carried out on the Diaspididae in New Zealand is briefly reviewed. Biology and life cycle, scale cover formation, natural enemies, distribution, host plant associations including galls, and economic importance are discussed. Methods are given for slide-mounting Diaspididae as used in the New Zealand Arthropod Collection. Morphology and terms are detailed for adult females, male and female 2nd-instar nymphs, and 1st-instar nymphs. Lists of plant hosts, material examined, and georeferenced collection localities are included as appendices.
