World review of the genus Tinocallis (Hemiptera: Aphididae, Calaphidinae) with description of a new species
AbstractThe aphid genus Tinocallis Matsumura is revised on a worldwide basis. Notes on its taxonomic position and evolutionary history and a key for the 21 species are presented. Tinocallis ussuriensis Pashtshenko and T. nevskyi lianchengensis Zhang and Qiao are proposed as synonyms of T. takachihoensis, and T. sapporoensis Higuchi is proposed as a synonym of T. nikkoensis Higuchi, T. allozelkowae Zhang and Zhong as a synonym of T. viridis (Takahashi), and T. magnoliae AK Ghosh and Raychaudhuri as a synonym of T. insularis (Takahashi). Tinocallis distinctus MR Ghosh, AK Ghosh and Raychaudhuri is returned to the subgenus Tinocallis s.s. from the subgenus Quednaucallis Chakrabarti. A lectotype designation was made for T. viridis (Takahashi). Tinocallis dalbergicolasp.nov. from Dalbergia hancei Benth. (Fabaceae) in Hong Kong is described and illustrated. It is closely related to T. caryaefoliae (Davis) and T. himalayensis AK Ghosh, MR Ghosh and Raychaudhuri, but has much longer antennae and longer spinal body processes. It also differs from the former species by the smooth mesonotum and from the latter species in having the forewing hyaline and with a complete radial sector.
