Diagnosis. This species differs from E. lorien , E. nebulosus , E. similis and E. tropicus in having a short, broad metanepisternum and sharply acute scutellar shield and in lacking hind wings and a notched inner eye margin. The species differs from E. brindabellae , E. dorrigo , E. minutus and E. tasmaniae in having a red pronotum and black elytra, from E. bicolorellus in being longer than 2.00 mm with a black head and darker undersurface, from E. protibialis in the much darker undersurface, shorter, broader terminal antennomere and unmodified fore legs in the male and from E. limitaris in the broadly rounded terminal antennomere, slightly smaller size (usually less than 2.4 mm) and broader body (less than 1.80 times as combined elytral width).

Description. Length 2.00–2.50 (2.30 ± 0.15) mm; body 1.66–1.83 (1.78) times as long as combined elytral width; greatest depth 0.61–0.68 (0.64) times elytral width. Colour of pronotum red; head, scutellar shield and elytra black; undersurfaces and legs dark brown to black, antennae usually brown and palps yellow. Head 0.92 times as long as wide; distance across eyes 1.17 times distance between them; inner edges of eyes not notched. Labrum 0.41 times as long as wide; sides straight, converging to subtruncate and minutely crenulate apex. Antenna about 1.7 times as long as head width; 3rd antennomere 0.80 times as long as 4th; 11th antennomere 1.57 times as long as 10th, 1.38 times as long as wide and broadly rounded at apex. Mandibular mola reduced. Galea slightly wider than lacinia, not widened apically. Apical maxillary palpomere subulate, 2.00 times as long as wide, with short aciculate tip. Apical labial palpomere subulate, 2.00 times as long as wide with moderately long aciculate tip. Pronotum 0.386–0.52 (0.45) times as long as wide. Scutellar shield 0.19 times as wide as pronotum, 0.54 times as long as wide and apically acute. Elytra 1.34–1.52 (1.44) times as long as combined width and 3.53–5.50 (4.29) times as long as pronotum; elytral punctation and vestiture as in Fig. 77 View FIGURES 73–88 . Hind wings absent. Metanepisternum 0.58 times as long as mesepimeron, subtriangular, with straight anterior edge, slightly curved inner and outer edges and narrowly rounded posterior angle. Metacoxal plate with outer edge about 3.6 times as long as posterior edge, which is weakly triemarginate. Protibia in male slender and basal protarsomeres not expanded. Outer (acute) mesotibial spur in male 0.45 times as long as first mesotarsomere, inner spur very slightly longer, parallel-sided with a blunt, cleft apex. Sternite VII in male 0.75 times as long as wide with weakly emarginate apex; sternite IX 2.18 times as long as wide with basal strut 0.46 times as long as body of sternite. Parameres at about middle about as wide as penis at same point, the apex of each weakly curved mesally; penis gradually narrowed to subacute apex, ending well before parameral apices.
