Diagnosis. Distinguished from other related fulviine genera by the following characters: rather ovoid body shape; brown-castaneous basic coloration; uniformly distributed, short, silvery, scalelike setae covering body surface, that are broadened toward apex ( Fig. 1 View FIGURE 1 ; Wolski & Gorczyca, 2014, figs. 25–26, 29, 32); generally matte or shagreened dorsum and thoracic pleura (Wolski & Gorczyca, 2015, fig. 29, 32); vertex with T-shaped shallow groove, composed of longitudinal, medial groove and transverse concaved region situated near posterior margin of vertex ( Wolski & Gorczyca, 2014, figs. 25–26); short, filiform antennal segments III and IV; labial segment I short, weakly reaching beyond middle of gula ( Fig. 1 View FIGURE 1 C); hemelytron strongly narrowed basally with distinct tubercles at constricted portion ( Wolski & Gorczyca, 2014, fig. 29); scent gland efferent system absent ( Wolski & Gorczyca, 2014, fig. 32). Further diagnostic characters are provided by Gorczyca (1999).

Discussion. Euchilofulvius is readily recognized by the above characters, particularly the silvery, scalelike setae, each of which has the flattened, apically widened shape, T-shaped shallow groove on the vertex, short labial segment I, basally constricted hemelytron with a row of distinct tubercles, and greatly reduced scent efferent system ( Fig. 1 View FIGURE 1 C; Wolski & Gorczyca, 2014, 25–26, 29, 32). Gorczyca (1999) suggested two subgenera, Euchilofulvius s. str. and Lepidofulvius Poppius. Based on his classification system, the below-described new species may belong to the latter subgenus. However, we do not use subgeneric level taxa in this work, because two subgenera are currently separated from each other only by the structure of the antennal segment II.
