The genus Castanopsides Yasunaga, 1992 belongs to the subfamily Mirinae and comprises 11 species worldwide. Prior to this study, two species, C. kerzhneri Josifov and C. potanini Reuter has been recorded from the Korean Peninsula.
The genus Castanopsides Yasunaga, 1992 belongs to the subfamily Mirinae and comprises 11 species worldwide. Prior to this study, two species, C. kerzhneri Josifov and C. potanini Reuter has been recorded from the Korean Peninsula.
In this paper, three species are recognized including a new record, C. falkovitshi (Kerzhner, 1979). Images of dorsal and ventral habitus, and male and genitalic structures are provided. A key to the Korean Castanopsides species is presented.

In this paper, C. falkovitshi (Kerzhner, 1979) is reported for the first time in Korea. The dorsal habitus and genitalic structures of both sexes are provided, along with a key to Korean Castanopsides species.
All specimens are deposited in the Insect Collection, Seoul National University (SNU), South Korea. Digital images of dorsal habitus are taken with a Canon EOS 70D, with a Canon MP–E 65–mm F2.8 1–5x macro lens. Genital structures are dissected and observed under a Leica DM 4000B microscope, and images are taken using a digital camera attached to the microscope (Lumenera Infinity 3). All measurements (mean and range) are provided in millimeters.
Terminology used to describe the male and female genitalia follows
Castanopsides
Castanopsides in East Asia can be recognized by the following characters: Body elongate oval, moderate to large size; dorsum covered with pale sericeous setae; antennae slender, segment I and II incrassate apically; labium rather short, not over metacoxa; male endosoma membranous, with a sclerotized, elongated spiculum and thick-rimmed secondary gonopore; hypophysis of left paramere hooked, sensory lobe rather tumid, or with sparsely toothed process; right paramere elongate, apex of hypophysis crooked; sclerotized ring elongate ovoid, usually not adjacent each other. For detailed diagnostic characters, see
This genus relate to five other genera which distributes at Palearctic and Oriental region; Gotoshinomiris Yasunaga, Liocapsus Poppius, Mahania Poppius, Orientocapsus Yasunaga & Schwartz, and Philostephanus Distant. Morphological charactier of them are superficially similar, so careful diagnosis is need.

Previously, phylogenetic research on Castanopsides and allied genera has been conducted.
Although large amount of study have been conducted about their relationship, additional study for establish their cladistic relationship is still needed, with more comprehensive basis (
