Nidularia japonica Kuwana, 1918 (Kermesidae: Nidularia)

Nidularia japonica Kuwana 1918: 131. Type data: JAPAN: Kyushu, on Quercus glandulifera. Syntypes, unknown, Type depository: Ibaraki-ken: Insect Taxonomy Laboratory, National Institute of Agricultural Environmental Sciences, Kannon-dai, Yatabe, Tsukuba-shi, (Kuwana), Japan; accepted valid name Illustr.
Quercetococcus iaponicus (Kuwana, 1918); Lindinger 1943b: 264. change of combination
Quercetococcus kuwanai Lindinger 1943b: 264. replacement name that is unjustified Replacement name for Nidularia iaponica Kuwana 1918 Notes: Lindinger (1933a) placed the eriococcid Eriococcus japonicus (=iaponicus) Kuwana 1902 in Nidularia. Lindinger (1943b) noticed that the kermesid Nidularia japonica (=iaponica) Kuwana 1918 was a junior secondary homonym and proposed the replacement name Quercetococcus kuwanai. As can be seen, he placed the kermesid N. iaponica Kuwana 1918 (=kuwanai) Lindinger 1943b in Quercetococcus. In effect, there was no secondary homonomy because the two species epithets were never congeneric making the name Q. kuwanai an unnecessary replacement name.

Systematics: This species has been treated as a junior synonym of Asiacornococcus japonicus by Lindinger (1933a), but is quite distinct; being placed in a separate family. The external appearance of this species resembles that of Gossyparia, but the reduced or absent legs in adults suggest a relationship with the Kermesidae. The family placement of this species needs to be studied. Nidularia japonica can be told from N. pulvinata by the following: 4 pairs of long setae in a transverse row behind anal ring in adult female and 4 pairs of quinquelocular disc pores on the venter of head and thorax of first instar nymph (Liu et al., 1997).
Structure: Adult female oval, moderately convex, dark gray to brown, dorsal surface with distinct ridges; matured adult female sclerotized and turtle-shell shaped, dorsal midline ridge, with white and nest-like ovisac covering the sides of body; 2.8–6.0 mm long. Male covered by a loose cottony white wax. (SuhSo2017)
