Discovery pattern and species number of scale insects (Hemiptera: Coccoidea).

ABSTRACT: Few investigations have been made of the species description trend of scale insects. The present study reports the discovery pattern and taxonomic efforts for this group based on global species and a literature dataset. In addition, three asymptotic models (Logistic, Gompertz, and Extreme Value) based on a discovery curve were used to predict the species number of scale insects. Our results showed that the species description rate has been changing over time, with certain peaks and valleys in the past 250 years. The mean number of species described per year was 30, with the highest number of 195 described species in 1985. The increasing number of authors and the almost constant proportion of species described by 10% most prolific authors since the 1900s suggested that taxonomic effort has been increasing over time. The Gompertz model with lowest AIC value suggested that there are about 10,450 species of scale insects on Earth, nearly 30% of which remain to be described. Our study offers insights into the discovery pattern of scale insect diversity.

Project description:Eight new Australian species of Poliaspis are described and illustrated: Poliaspis alluviasp. n., Poliaspis araucariaesp. n., Poliaspis ceraflorasp. n., Poliaspis naambasp. n., Poliaspis nalbosp. n., Poliaspis narungga sp. n., Poliaspis ozothamnaesp. n., and Poliaspis waibenensissp. n. Two described species are transferred into Poliaspis and are redescribed and illustrated: Lineaspis callitris (Laing) originally described by Laing as a species of Poliaspis, is transferred back into Poliaspis as Poliaspis callitris Laing, comb. rev., and Leonardaspis wilga (Leonardi) is transferred to Poliaspis as Poliaspis wilga (Leonardi), comb. n. Descriptions and illustrations are also provided for six of the fourteen previously-named Poliaspis species, including five from Australia: Poliaspis attenuata Brimblecombe, Poliaspis elongata Brimblecombe, Poliaspis exocarpi Maskell, Poliaspis nitens Fuller, and Poliaspis syringae Laing. Both Poliaspis cycadis Comstock and Poliaspis gaultheriae Green become junior synonyms of Poliaspis media Maskell. The species not treated here are Poliaspis intermedia Fuller (the location of the types is unknown and Fuller's description is inadequate), Poliaspis casuarinicola Lindinger (missing types), Poliaspis incisa Takagi and de Faveri (recently, and well described in Takagi and de Faveri 2011), and the six New Zealand species recently revised by Henderson (2011). In addition, Laingaspis lanigera (Laing), the adult female of which has 8 clusters of perivulvar pores - as in Poliaspis species - is redescribed and illustrated. Lectotypes are designated for Laingaspis lanigera, Poliaspis callitris, Poliaspis exocarpi, Poliaspis media, and Poliaspis wilga. A key is provided to the species of Poliaspis, excluding Poliaspis casuarinicola and Poliaspis intermedia butincluding Poliaspis incisa and the New Zealand species: Poliaspis chathamica Henderson, Poliaspis floccosa Henderson, Poliaspis lactea (Maskell), Poliaspis media Maskell, Poliaspis raouliae Henderson and Poliaspis salicornicola Henderson.
