( Figs 13–14 , 43 , 56 , 81 , 106 , 122, 131 ) 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 a notched inner eye margin and hind wings. It differs from E. minutus in its larger size (length greater than 1.85 mm ), from E. minutus , E. dorrigo , E. brindabellae and E. tasmaniae in the red pronotum and black elytra. It differs from E. bicolorellus in its larger size (greater than 2.0 mm), black head, and longer, narrower apical antennomere (more than 1.50 times as long as wide) with truncate apex. From E. bicolor it differs in having the pronotum, scutellar shield and sides of elytra red, the apical antennomere widened and subtruncate apically. This is the largest of the wingless species, usually more than 2.3 mm long, with the body more than 1.8 times as long as combined elytral width. Description. Length: 2.20–2.80 (2.63 ± 0.15) mm; body 1.80–1.95 (1.88) times as long as combined elytral width; greatest depth 0.60–0.66 (0.63) times combined elytral width. Colour of head black; pronotum and sides of elytra red; main portion of elytra black, scutellar shield black or red; undersurfaces reddish anteriorly, brownish posteriorly; legs and antennae yellowish-brown. Head 0.97 times as long as wide; distance across eyes 1.45 times as great as distance between them; inner eye margin without notch. Labrum 0.56 times as long as wide; sides weakly curved and converging to slightly emarginate apex. Antenna about 1.82 times as long as head width; 3rd antennomere equal in length to 4th; 11th antennomere 1.18 times as long as 10, 1.86 times as long as wide, with subtruncate apex. Galea about 1.33 times as wide as lacinia, not widened apically. Apical maxillary palpomere subulate, about 2.53 times as long as wide, with short mesal aciculate papilla. Apical labial palpomere subulate, 1.67 times as long as wide, with long aciculate papilla. Pronotum 0.38–0.49 (0.42) times as long as wide; prosternal process abruptly narrowed preapically with subacute apex. Scutellar shield 0.21 times as wide as pronotum and 0.65 times as long as wide at base and apex acute. Elytra 1.47–1.63 (1.54) times as long as combined width and 4.17–5.00 (4.55) times as long as pronotum; punctation and vestiture as in Fig. 81 . Hind wings absent. Metanepisternum 0.52 times as long as mesepimeron and 1.08 times as long as wide, very asymmetrically triangular with straight anterior edge, strongly rounded outer edge and weakly rounded outer edge. Metacoxal plate with outer edge about 4.4 times as long as posterior edge, which is moderately deeply biemarginate. Outer (acute) mesotibial spur in male 0.50 times as long as first mesotarsomere, inner one about equal in length with a blunt, cleft apex. Parameres at about middle 1.5 times as wide as penis at same point, very slightly curved mesally with broadly rounded apex. Penis with sides gradually converging to subapex, then very slightly diverging before subacute apex. Types: Holotype , ♁: “ 28.14S 123.08E , QLD, Lamington NP, near O’Reilly’s 25 Oct. 1993 , S. A.
