Taxonomic remarks
. This species was originally described from Hubei Province,
China
as
Oedothorax rimatus
by
Ma & Zhu (1990)
. It seems to be especially closely related to the Chinese and Japanese
Gongylidioides onoi
Tazoe 1994
(=
Aprifrontalia quadrialata
Gao, Xing & Zhu 1996
), but is easily distinguished by the less strongly developed head elevation on the male carapace, the absence of a deep distal hollow on the paracymbium, as well as by the less strongly narrowed epigynal plate.
