Diagnosis: E. schopfi n. sp. is clearly recognizable by the extended pronotum and elytra. The metatibiae are conspicuously extended and there are fine wrinkles around the elongated pronotal groove. The phallic tip is notched, with a spoon-like structure; the spicular fork is only fused for less than one-sixths of its length.

Length: (9 specimens measured) Total length: 17–21 mm.

Head: Black, with isolated pilosity; with very dense punctation, fine wrinkles; epistomal suture very distinct; interocular space about one to 1.5 one eye width.

Thorax: Pronotal length to width ratio 1.15:1; pronotum black, with isolated hairs, dense punctation and fine wrinkles; sides sinuate, slightly convergent towards apex, conspicuously longer than broad; grooves of sub-basal collar not very distinct, separated by a bar. Scutellum black, with dense punctation.

Elytra: Elytral length to width ratio 3.02:1; elytra black, in the middle with a reddish or yellow transverse fascia; with isolated pilosity; elytral base slightly wider than pronotum, slightly broader behind the middle; elytra three times as long as wide; diameter of punctations in basal half wider than interstices, towards apex smaller, diameter of punctations in striae 1 to 4 conspicuously smaller, diameter of punctations in striae 5 to 8 slightly smaller than interstices, punctations of tenth stria distinct almost towards apex; punctations of ninth stria vestigial; elytral punctation with three nodules; interstices 2, 4, 6 and 8 slightly ridged from middle, interstices with distinct microsculpture.

Lower surface: Black, with isolated pilosity; especially metaventrite with very dense punctation and fine wrinkles; procoxal cavities closed posteriorly.

Legs: Black, with dense pilosity, with very dense punctation and fine wrinkles; mesotibiae slightly bent, metatibiae conspicuously extended.

Abdomen: Tegmen ventrally open; phallic tip with a notched, spoon-like structure; spicular fork fused for less than one-sixth.

Distribution: New South Wales and Victoria.

Seasonal occurrence: Collected in August, October and December.

Etymology: Named after Prof. Dr. Reinhard Schopf, a colleague of the senior author at the Department of Animal Ecology.
