Rhombissus harimensis (Matsumura, 1913)

Issus harimensis Matsumura, 1913: 61 .

Rhombissus brevispinus Che, Zhang et Wang in ZHANG et al. 2020: 359, fig. 143, pl. 27 j–l, syn. n.

Notes. All important features of the peculiar male genitalia of Rh. harimensis , with an anal tube turned downwards apically, ventral aedeagal hooks with short upper processes, and ventral phallobase lobe with small apical concavity ( GNEZDILOV & HAYASHI 2016: figs 1–4) are readily recognizable in the illustrations accompanying the original description of Rh. brevispinus . The fact ZHANG et al. (2020) did not compare their new species with the evidently very closely related Rh. harimaensis suggests that they likely overlooked this species. Therefore, there is no reason to treat the Chinese continental population as a species distinct from the one occurring in the Japanese Islands, even if the latter population is characterized by a somewhat larger size which might be due to island isolation. The synonymy of these two names is accordingly proposed.
