Adults of Euphitrea flavicornis are similar to those of E. jungchani sp. nov. with normal humeral calli on elytra (reduced in E. houjayi sp. nov.) and oval bodies and elytra 1.2 – 1.3 longer than wide (transversely oval bodies and elytra 1.1 × longer than wide in E. tsoui sp. nov.). In addition to the allopatric distributions of both species, some genital structures are diagnostic, including straight apices of aedeagi of E. flavicornis in lateral view (Fig. 3 D) and membranous tectum (Fig. 3 C) (aedeagi of E. jungchani sp. nov. subapically curved in lateral view (Fig. 8 D) and sclerotized tectum (Fig. 8 C )), swollen spermathecal receptaculum (Fig. 3 I) (not swollen in E. jungchani sp. nov.; Fig. 8 I), and comparatively narrower apices of abdominal ventrite VIII in females (Fig. 3 F) (comparatively wider apices of abdominal ventrite VIII in females of E. jungchani sp. nov.; Fig. 8 F).	en	Lee, Chi-Feng (2025): The genus Euphitrea Baly, 1875 (Coleoptera, Chrysomelidae, Galerucinae, Alticitae) in Taiwan, with description of three new species.

96E2102FA40F5845AF47BC665B47C7D8.taxon	distribution	Distribution. Central and south Taiwan (Fig. 5). Whether populations of this species can survive at Mt. Alishan, more than 2000 m elevation, is unknown. Specimens collected from Mt. Alishan are more than 100 years old. The word “ Arisan (= Alishan) ” during the past may refer to a much wider range than at present, indicating the whole township. Thus, these old specimens may not have been collected at high altitudes.	en	Lee, Chi-Feng (2025): The genus Euphitrea Baly, 1875 (Coleoptera, Chrysomelidae, Galerucinae, Alticitae) in Taiwan, with description of three new species.

Adults of Euphitrea nisotroides are similar to those of E. taiwana with similar color patterns, but E. nisotroides can be easily recognized by its distinct, elongate longitudinal ridge on the vertex of the head (Fig. 2 E) (short longitudinal ridges on the vertex in E. taiwana; Fig. 2 F).

Adults of Euphitrea taiwana are similar to those of E. nisotroides with similar color patterns, but E. taiwana can be easily recognized by the shorter longitudinal ridges on the vertex of the head (Fig. 2 F) (long longitudinal ridges on vertex in E. nisotroides (Fig. 2 E )).
