Type species.

Aclerda biwakoensis   Kuwana by monotypy and original designation.


Nipponaclerda   are classified within the subfamily Aclerdinae  Cockerell ( Hodgson and Millar 2002), with Aclerda   Signoret and Lecanaclerda   Hodgson & Millar. Members of this genus are similar to species of Aclerda   but can be distinguished in the adult female stage by the poor development of anal ring setae, which are few in number, shorter than the anal plate, and never extend beyond the body apex ( Borchsenius 1960). In adult females of Aclerda   , these setae are numerous, long, and usually protrude beyond the posterior body margin; however, these setae fail to extend beyond the margin in A. pasquieri   Balachowsky, A. sinaloaensis   McConnell, and A. subterranea   Signoret. Additionally, dorsal conical pores (referred to as invaginated setae in McConnell 1954) can be found in species of Aclerda   but are absent from Nipponaclerda   . There are no discernable differences between the immature instars of these two genera but adult males of Nipponaclerda   can be differentiated by the encircling marginal setae, absence of dorsal invaginated conical pores, and reduction in the number of anal ring setae ( McConnell 1954). The adult male stage has only been described for N. biwakoensis   .

The list of host genera reported in ScaleNet (; last accessed 19 March 2019) for Nipponaclerda   species includes: Agropyron   , Bambusa   , Fargesia   , Phragmites   , Sorghum   ( Poaceae  ), and Juncus   ( Juncaceae  ) ( Borchsenius 1960; García Morales et al. 2016; McConnell 1954; Wang 1994; Wang and Zhang 1994; Zhang 1998).
