(Figs 24–25, 34, 45, 62, 84, 110, 113, 118, 124, 127, 139)
Diagnosis. This species differs from E. bicolor, E. bicolorellus, E. brindabellae, E. dorrigo, E. limitaris, E. minutus, E. protibialis and E. tasmaniae in having a longer and narrower metanepisternum, less sharply acute scutellar shield, internal eye notch and hind wings. It differs from E. lorien and E. similis in having a shorter and broader body (less than 1.9 times as long as wide; elytra together less than 1.57 times as long as wide) and the apical maxillary palpomere widest at the middle with an acute apex. It differs from E. tropicus in having the body entirely black and the apical antennomere less than 1.8 times as long as wide.
Description. Length: 2.10–2.40 (2.21 ± 0.09) mm; body 1.69–1.86 (1.70) times as long as combined elytral width; greatest depth 0.68–0.76 (0.71) times elytral width. Colour of most surfaces black; legs and antennae reddishbrown to yellowish-brown. Head 0.96 times as long as wide; distance across eyes 1.41 times distance between them; mesal eye margin with distinct notch. Labrum 0.71 times as long as wide, with sides almost straight and converging to subtruncate apex. Antenna about 1.95 times as long as head width behind eyes; 3rd antennomere 0.77 times as long as 4th; 11th antennomere 1.19 times as long as 10th, 1.58 times as long as wide and subtruncate at apex. Mandibular mola well-developed. Galea slightly wider than lacinia, expanded at apex. Apical maxillary palpomere 2.75 times as long as wide, with narrowly, obliquely truncate apex. Apical labial palpomere subulate, 2.5 times as long as wide with moderately long aciculate tip. Pronotum 0.34–0.45 (0.38) times as long as wide; prosternal process subacute at apex. Scutellar shield 0.17 times as wide as base of pronotum, 0.82 times as long as wide at base, with subacute apex rounded at tip. Elytra 1.40–1.55 (1.48) times as long as combined width and 5.91–4.92 (5.21) times as long as pronotum; elytral punctation and vestiture as in Fig. 84. Hind wings fully developed. Metanepisternum 1.26 times as long as mesepimeron, 1.94 times as long as wide, asymmetrically quadrate with strongly rounded inner edge, straight outer edge, and obliquely truncate posterior edge. Metacoxal plate with outer edge about 2.7 times as long as posterior edge, which is minutely emarginate near its mesal end. Outer (acute) mesotibial spur in male 0.46 times as long as first mesotarsomere, inner spur equal in length to outer one, parallel-sided with a blunt, cleft apex. Meso- and metapretarsal claws each with a slender, acute accessory lobe almost as long as the claw. Parameres 1.22 times as wide at about middle as penis at same point, distinctly curved mesally before apex, which is narrowly rounded. Penis gradually narrowing to subapex, then slightly expanded before acute apex, ending well before parameral apices.
