Diagnosis: Distinguished by body yellowish brown; head entirely dark brown; first antennal segment dark brown; first labial segment dark brown; pronotum with a pair of dark markings ( Fig. 1C ); left paramere rounded, process of sensory lobe long and straight dorsally, lateral tooth distinctly developed ( Figs. 3 A–B); right paramere thick, hypophysis straight, its apex blunt ( Fig. 3C ); endosomal spicule thin, as long as membranous lobe, curved and winding subapically; lateral sclerite I short and clavate; lateral sclerite II broad with tiny spinules on the whole; medial sclerite as long as spicule and membranous lobe ( Figs. 3 D–F); sclerotized ring oval; sclerotized perimeter of combined common oviduct and dorsal wall of genital chamber narrowly developed; medial sclerite of combined common oviduct and roof of genital chamber developed medially ( Fig. 3E ); dorsal structure circular and small with tiny spinules on the whole ( Fig. 3F ).

Description: see Miyamoto & Yasunaga (1992) for description of external morphology.

MALE GENITALIA: Left paramere rounded dorsally; hypophysis long and curved at apex, its apex blunt; sensory lobe with narrow and long process ( Fig. 3A ), with noticeable tooth laterally ( Fig. 3B ); right paramere thick, with long and narrow hypophysis, its apex blunt ( Fig. 3C ); endosoma membranous, secondary gonopore wider than maximal width of ductus seminis part, with one spicule and three sclerites; sp thin and as long as membranous lobe, curved subapically, its apical part winding; ls I short and clavate; ls II broad with tiny spinules on the whole; ms bifurcated, as long as sp and membranous lobe, length of each part similar ( Figs. 3 D–F).

FEMALE GENITALIA: sr oval, not closed to each other, msgc narrowly developed medially, spgc narrowly developed ( Fig. 3G ); irl not surpassing irs, irl with distinct small spinules, ds small, circular, with small spinules on whole part ( Fig. 3H ).

Material Examined: [ CNU] 1♂, Jungmi-san (Mt), Sinbok-ri , Okcheon-myeon , Yangpyeong-gun, Gyeonggido, South Korea, on Acer pictum subsp. mono , 16.v.2015, J. Kim leg.; [ CNU] 2♂♂ 2♀♀, Jungmi-san (Mt), Sinbokri , Okcheon-myeon, Yangpyeong-gun, Gyeonggi-do, South Korea, on Acer pictum subsp. mono , 16.v.2015, J. Kim leg.; [ CNU] 2♂♂ 3♀♀, Tongbang-san (Mt), Myeongdal-ri , Seojong-myeon, Yangpyeong-gun, Gyeonggi-do, South Korea, on Acer pictum subsp. mono , 16.v.2015, J. Kim leg.

Distribution: Korea, Japan, China, Russia.

Hosts: Acer pictum subsp. mono * ( Aceraceae ).

Biology: This species is associated with Acer pictum subsp. mono (Aceraceae) in May with a one generation per year, and is attracted to the light trap.

Remarks: The character state ‘having noticeable lateral tooth of left paramere’ is clear in this species, and one of the important characters within Rhabdomiris . However, Miyamoto & Yasunaga (1992) did not describe and illustrate lateral tooth of left paramere of this species collected from Japan. It is unclear whether this inconsistency is due to variation from different populations, the authors just omitted this character in illustration, or examined specimens being not conspecific.
