The family Qinococcidae includes 10 species in 4 genera, distributed in the Oriental and Palaearctic Regions. There are three monotypic genera, Abrococcus Zheng & Wu , Jansenus Foldi and Qinococcus Wu ; and 7 species in the genus Neogreenia MacGillivray ( García Morales et al. 2016, Zheng & Wu 2023a, 2023b). The species in Qinococcidae differ from those in other coccid families by having on the adult female: (i) antennae much reduced or, if present, with 10 segments, (ii) thoracic and developed abdominal spiracles each with sieve-like disc-pores in atrium and (iii) vulva opening longitudinally; in the adult male: (i) a strongly sclerotized series of ridges forming medial sub-pentagonal shape on ventral part of epicranium and (ii) a post-tergite shaped like inverted “π”; also on the first-instar nymphs: (i) antennae 7 segmented, with the two terminal segments expanded (Wu et al. 2022; Zheng & Wu 2023a, 2023b).
