Diagnosis: E. villosa n. sp. is distinguished by the wide interocular space, in combination with subparallel elytra (in contrast to the dilated elytra of E. hirta ) and the diameter of elytral punctation not decreasing towards apex. The ridged elytral interstices 2, 4, 6, and 8 are particular of E. hirta . Although the aedeagi of E. villosa n. sp. and E. hirta are similar, the spicular fork of E. villosa n. sp. is fused to one-third its length (one-fifth in E. hirta ).

Length: (63 specimens measured) Total length: 11–17mm.

Head: Dark brown to black, with dense pilosity; with dense punctation and fine wrinkles; epistomal suture distinct; interocular space about 1.5 to double eye width.

Thorax: Pronotal length to width ratio 1.13:1; pronotum dark brown to black, with dense pilosity; pronotum parallel towards apex; with dense, large and small punctation, sides inconspicuously wrinkled or without wrinkles; grooves of sub-basal collar less distinct, separated by a wide bar or fused. Scutellum dark brown to black, with dense punctation and pilosity.

Elytra: Elytral length to width ratio 2.36:1; elytra dark brown to black, with dense pilosity; elytral base slightly broader than pronotum, sub-parallel towards apex; elytral punctation in basal half as wide as interstices, not decreasing towards apex; elytral punctation with three nodules; punctations of tenth stria distinct almost towards apex; punctations of ninth stria vestigial; interstices 4 and 6 slightly ridged behind the middle, all other interstices flattened, with distinct microsculpture.

Lower surface: Dark brown to black, with dense pilosity; mesoventrite, metaventrite and abdominal ventrites with dense punctation; procoxal cavities slightly opened to almost closed posteriorly.

Legs: Dark brown to black, with dense pilosity, with dense punctation and fine wrinkles; mesotibiae bent.

Abdomen: Tegmen ventrally closed; phallic tip Z-shaped; spicular fork fused to one-third.

Distribution: Mainly in northern parts of Australia and some localities in the south.

Seasonal occurrence: Collected from November to March.

Etymology: The specific epithet, villosa , a Latin adjective refers to the dense pilosity.
