A new psyllid genus from Taiwan, Danieliana gen. nov. (Hemiptera: Psylloidea: Psyllidae)

A new genus, Danielianagen. nov., in the subfamily Amorphicolinae (Psyllidae) is described, and one new species is described from Taiwan, D. manmiaoyangaesp. nov. The definition of the subfamily Amorphicolinae previously based solely on Amorphicola is broadened to incorporate characteristics of the new genus not shared with Amorphicola. Amorphicola with two species from North America and Danielianagen. nov. from Taiwan, are strongly supported grouping together in Amorphicolinae based on mitogenome data. The morphological and molecular divergence between the two genera is reflected in the placement in separate tribes within the subfamily (Amorphicolini trib. nov. and Danielianini trib. nov.). The host plant of D. manmiaoyangaesp. nov. is Caesalpinia crista (Fabaceae), and the immatures are free-living with eggs found on emerging foliage. The genus name and species name honour entomologists, Daniel Burckhardt and Man-Miao Yang, who together have contributed enormously to the knowledge of the psyllid fauna of Taiwan, as well as to a wide breadth of research that has furthered our understanding of psyllids.
