03EB87EBFF86F81A808AFB6DCD28C7A5.taxon	discussion	Remarks. The three-looped demarcated ocellar region is a synapomorphy of the Stichillus species and has been used traditionally in species identification. Many species, however, have very similar characteristics in ocellar regions that are indistinguishable from one another (e. g., S. japonicus and S. koreanus sp. nov., as in Fig. 2 C – F). Furthermore, the shape of the ocellar region shows some degree of intraspecific variation in same sex (Fig. 3), as well as in between sexes (Fig. 2 E, F). Although the unusual types of ocellar region of some species can be a good diagnostic character for the species (e. g., the Chinese species S. suspectus (Brues) and S. tuberculosus Liu & Chou, see Liu 2001: figs. 68, 74), the usefulness of shape of ocellar region in species identification is in doubt due to high degree of intraspecific variation and interspecific similarity.	en	Lee, Jun-Ho, Kim, Sam-Kyu (2023): A taxonomic study on the genus Stichillus (Diptera: Phoridae) from South Korea, with a key to species from East Asia.

03EB87EBFF85F81E808AFF50CFCAC1AB.taxon	discussion	Remarks. The aedeagus of S. cylindratus from Korea is slightly different from that of Japanese specimens illustrated in Nakayama & Shima (2004): left lower apical margin of dorsal plate not extended ventrally (slightly extended ventrally in Japanese specimen); right apical curved process usually long, reaching apical margin of left hooked process (short, not reaching apical margin of left hooked process in Japanese specimen). The hypopygium is similar to the Chinese species S. acuminatus Liu & Chou, but can be readily distinguished from the latter by position of inner projection of hypandrium and morphology of aedeagus.

This species was collected in mountainous area of relatively low to high altitude, about range of 200 – 1900 m above sea level in South Korea, similarly with S. japonicus but altitudinal distribution range was broader than the latter. Adults can be found on leaves of wood fern or broadleaf shrubs in deep forest or rock surfaces covered with moss in streamside showing wandering or feeding behavior (Fig. 11). Detailed ecological information including larval feeding habits is largely unknown.	en	Lee, Jun-Ho, Kim, Sam-Kyu (2023): A taxonomic study on the genus Stichillus (Diptera: Phoridae) from South Korea, with a key to species from East Asia.

This species is somewhat similar to S. japonicus but can be readily distinguished from the latter by characteristics of fore apical tarsomere, male hypopygium and female postabdomen (see remarks of S. japonicus above). The hypopygium of S. koreanus sp. nov. is also similar to Chinese species S. acuminatus but can be readily distinguished from the latter by the following characteristics: posterodorsal margin of epandrial lobe rounded (nearly straight in S. acuminatus); dorsal plate of aedeagus curved with angle more than 90 °, with blunt apex (curved with angle less than 90 °, with pointed apex in S. acuminatus) (characteristics of S. acuminatus were referred to the illustrations and description of Liu 2001: 192, figs. 78, 79).

03EB87EBFF8CF815808AF8ABCAF6C71F.taxon	biology_ecology	Ecology. This species was collected widely in mountainous regions in South Korea. Altitudinal distribution of the species seemed relatively lower than those of S. japonicus and S. koreanus sp. nov., about under 800 m above sea level. Adults can be found on leaves of shrubs in shaded forest. Detailed ecological information including larval feeding habits is largely unknown.	en	Lee, Jun-Ho, Kim, Sam-Kyu (2023): A taxonomic study on the genus Stichillus (Diptera: Phoridae) from South Korea, with a key to species from East Asia.

03EB87EBFF8CF815808AF8ABCAF6C71F.taxon	discussion	Remarks. The dorsal plate of aedeagus of Korean specimens is curved nearly perpendicularly, as same with the Chinese specimens illustrated in original description (Liu & Chou 1996), while that of Japanese specimens is not perpendicularly curved (see Nakayama & Shima 2004: fig. 5 C, D). This might reflect some degree of geographical variation or just simply a difference in viewing angles. Distributions.
