Diagnosis.
This species can be recognized based on the following combination of characters: eyes almost as wide as the anterior margin of pronotum (
Figs 5A,B
;
9B,C
), pronotal punctation (
Fig. 9B,C
) very dense, with most punctures very close to each other, elytra together about 2.3 times as long as wide, the elytral surface (
Fig. 10K
) rather smooth and with mostly large punctures, and the median lobe (
Fig. 12H
) about 5.4–5.8 times as long as wide.
Sexual dimorphism.
Females are more robust and relatively shorter than males, being about 2.4–2.5 times as long as wide (excluding head; about 2.7 times in males;
Fig. 5A,B
). Females have shorter and less serrate antennae (serrations less acute) than males (
Sakai 1982
).
Distribution.
This is the most widespread Japanese
Eurypogon
, currently being known from Honshu, Shikoku, and Kyushu Islands (
Fig. 15
).
