Size, length 19–26 mm male, 19–22 mm female; width 8–9 mm. Dorsal vestiture of scales dense, arranged in transverse or oblique rows, glabrous areas between scales narrow, slightly if at all raised. Rostrum of female about subequal in length to pronotum, rostrum of male slightly longer than length pronotum, granulate dorsally. Pronotum lacking or with small tufts of erect hair-like scales. Midline of pronotum not tumid or raised above lateral regions, sculpturing of pronotum rather regular with no depressions or swellings. Creamy white scales of pronotum limited to along midline and in transverse very short bands at position of pronotal tufts in E. fasciculatus . Elytra with scales as on pronotum, dense, arranged in transverse rows, with slightly raised, very narrow glabrous spaces between rows; with fine tufts of elongate white hair-like scales between interstriae 2 and 3 at midlength, and between interstriae 3 and 4 at apical one-quarter. Sutural interstria, interstria 3, and humerus at most slightly swollen basally, all interstriae very slight if at all ascending posteriorly, elytra in profile more or less flat, not humped or tumid towards base. Legs with front tibia with inner margin in males with only a few subapical short hairs; femora on front and middle legs with inner margin with very small subapical tooth. Aedeagus of male very short and broad, apically emarginate, internal sac with single large, scythe-like apical sclerite.

Comments: Based on external characters this species and E. fasciculatus are quite distinct; however, the aedeagus of the males are surprisingly almost identical (compare figures 7 and 8).
