038D87FFFFB9351FFF67E8A1763AF8B0.taxon	etymology	Etymology. The species is named in honor of Dr. Tomohide Yasunaga, a prominent specialist in the taxonomy of Miridae, in recognition of his extensive contributions to the family, particularly in the Oriental Region including studies on the genus Eurystylus. The name is a noun in the genitive case.	en	Kim, Junggon, Keetapithchayakul, Tosaphol Saetung, Phan, Quoc Toan, Jung, Sunghoon (2025): Taxonomic review of the genus Eurystylus Stål (Hemiptera: Miridae: Mirinae) from Vietnam, including a new species description.

038D87FFFFB9351FFF67E8A1763AF8B0.taxon	discussion	Discussion. The new species differs from most congeners by the unicolorous fuscous dorsum. Eurystylus yasunagai sp. nov. is distinguished from the most similar congener from Taiwan, E. jingfui Yasunaga et al. 2017 by entirely fuscous posterior margin of propleuron (vs. posterior margin with white band); posterior part of mesepisternum creamy yellow (vs. mesepisternum entirely fuscous); plate dorsal to mesepisternum entirely creamy yellow (vs. mostly fuscous with yellowish margin); metepimeron entirely fuscous (vs. posterior part metepimeron white); and endosoma with three sclerites (vs. endosoma with one long and apically sharp sclerite). Meanwhile, in the original description of E. jingfui, Yasunaga et al. (2017) mentioned a population from Thailand and Southeast Asia that resembles E. jingfui but have white longitudinal striae on the lateral sides. Considering both external morphology and distribution, this population is most likely our new species, E. yasunagai sp. nov.	en	Kim, Junggon, Keetapithchayakul, Tosaphol Saetung, Phan, Quoc Toan, Jung, Sunghoon (2025): Taxonomic review of the genus Eurystylus Stål (Hemiptera: Miridae: Mirinae) from Vietnam, including a new species description.

038D87FFFFBE351AFF67EAD970FAFD0C.taxon	biology_ecology	Biology. This species has been found on the flowers of various broad-leaved trees (Yasunaga et al. 2017). In Korea, both nymphs and adults have been collected from Rhus chinensis (Anacardiaceae), which is the first record of the host plant of this species. In Vietnam, the specimen was also collected from the flowers of a broad-leaved tree.	en	Kim, Junggon, Keetapithchayakul, Tosaphol Saetung, Phan, Quoc Toan, Jung, Sunghoon (2025): Taxonomic review of the genus Eurystylus Stål (Hemiptera: Miridae: Mirinae) from Vietnam, including a new species description.

038D87FFFFBE351AFF67EAD970FAFD0C.taxon	discussion	Remarks. In the present study, we identified this species based on the examination of male genital characters (Fig. 2 I – K), which confirms its occurrence in southern Vietnam and thereby extends the known southern limit of its distribution. Notably, Yasunaga et al. (2017) synonymized E. luteus Hsiao, 1941, previously recorded from Korea, with this species. Our examination of specimens collected from North Korea (by M. Josifov) revealed identical genital structures, supporting this taxonomic treatment (Fig. 2 L). Furthermore, this species is distributed throughout the Korean Peninsula, including Jeju Island. Genetic analysis of the cytochrome c oxidase subunit I (COI) gene from populations collected across Korea – from Jeju Island to Gangwon-do near the northern border – revealed identical sequences. Some of these sequences have been published in public databases such as NCBI. Although COI sequences from the Vietnamese and North Korean populations were not available, the morphological uniformity and geographic continuity suggest, though do not definitively confirm, that these populations belong to the same species. Given the species’ broad host plant range and its ecological adaptability across both lowland and highland habitats, it is plausible that its actual distribution extends across much of the Indochinese Peninsula. Our findings therefore support the taxonomic treatment proposed by Yasunaga et al. (2017), while also highlighting the species’ potential for a much wider distribution than previously recognized.	en	Kim, Junggon, Keetapithchayakul, Tosaphol Saetung, Phan, Quoc Toan, Jung, Sunghoon (2025): Taxonomic review of the genus Eurystylus Stål (Hemiptera: Miridae: Mirinae) from Vietnam, including a new species description.
