Diagnosis: Pronotum with dense, large and small punctation, which is similar to E. debilis (though E. debilis is much more slender with extended pronotum and elytra). Pygidium compact, with very short and broad processes, ventrite VI deeply emarginate; phallobase dilated.

Length: (9 specimens measured) Total length: 15–17 mm.

Head: Black, with isolated pilosity; with dense large and small punctation; epistomal suture not distinct; interocular space about one to 1.5 one eye width.

Thorax: Pronotal length to width ratio 1.07:1; pronotum black, with isolated pilosity; conspicuously sinuate, slightly convergent towards apex; with dense, large and small punctation, sides wrinkled; grooves of sub-basal collar distinct, separated by a wide, distinct bar. Scutellum dark brown to black, with weak punctation.

Elytra: Elytral length to width ratio 2.54:1; elytra dark brown to black, with isolated pilosity; elytral base slightly broader than pronotum, elytra subparallel to slightly broader behind middle; elytral punctation at base conspicuously broader than interstices, punctations decreasing towards apex; punctations of tenth stria distinct almost towards apex; punctations of ninth stria vestigial (in one specimen with isolated small punctation); elytral punctation with three nodules; interstices flattened and almost not ridged, microsculpture weak or absent.

Lower surface: Dark brown to black, with isolated pilosity, especially metaventrite with dense punctation and fine wrinkles; procoxal cavities slightly opened posteriorly.

Legs: Black, with isolated pilosity, with dense punctation and fine wrinkles; mesotibiae bent.

Abdomen: Tegmen ventrally closed, sides open; phallobase dilated; spicular fork fused to halfway.

Distribution: Mainly Western Australia, one locality in New South Wales.

Seasonal occurrence: Collected from November to July.

Etymology: The specific epithet, punctata , a Latin adjective refers to the dense punctation of pronotum.
