( Figs 9–12 , 42 , 55, 70 , 80 , 91, 103 , 115–116 , 143–147 ) 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 , E. bicolorellus , E. bicolor , E. limitaris and E. protibialis in having the pronotum reddishbrown and the elytra yellowish-brown and from E. brindabellae and E. tasmaniae in the somewhat smaller size (less than 2.0 mm), apical antennomere more than twice as long as wide, apical maxillary palpomere obliquely truncate apically with aciculate tip at one edge and parameres distinctly bowed outwardly. Description. Length: 1.70–1.90 (1.81 ± 0.08) mm; body 1.78–1.88 (1.83) times as long as combined elytral width; greatest depth 0.61–0.69 (0.66) times combined elytral width. Colour of head, pronotum and scutellar shield reddish-brown, elytra yellowish-brown, undersurfaces reddish-brown anteriorly, lighter posteriorly; legs brown; antennae reddish-brown basally, yellow apically. Head 0.79 times as long as wide; distance across eyes 1.45 times as great as distance between them; inner edges of eyes not notched. Labrum 0.52 times as long as wide; sides weakly curved and converging to slightly emarginate apex. Antenna about 1.9 times as long as head width behind eyes; 3rd antennomere barely longer than 4th; 11th antennomere 1.14 times as long as 10, 2.22 times as long as wide and irregularly, broadly rounded at apex. Mandibular mola reduced. Galea about as wide as lacinia, not widened apically. Apical maxillary palpomere about 2.6 times as long as wide, widest at middle, evenly slightly curved laterally and barely narrowed to apical sixth, then obliquely truncate, and giving rise near outer edge to a short, slender, aciculate process. Apical labial palpomere subulate, 2.07 times as long as wide, with long aciculate apical process. Pronotum 0.39–0.45 (0.41) times as long as wide; apex of prosternal process angulate. Scutellar shield 0.27 times as wide as pronotum, 0.81 times as long as wide at base and apically acute. Elytra 1.45–1.55 (1.50) times as long as combined width and 4.21–5.17 (4.60) times as long as pronotum; punctation and vestiture as in Fig. 80 . Hind wings absent. Metanepisternum 0.48 times as long as mesepimeron and about as long as wide, asymmetrically triangular with straight anterior edge, strongly rounded inner edge and barely rounded outer edge, with apical notch at posterolateral corner. Metacoxal plate with outer edge about 4.0 times as long as posterior edge, which is moderately deeply biemarginate. Outer (acute) mesotibial spur in male 0.42 times as long as first mesotarsomere, inner one about equal in length, slightly sinuate with a blunt, cleft apex. Parameres at about middle as wide as penis at same point, distinctly curved outwardly at about middle, with subtruncate apex. Penis with sides gradually converging to subacute apex.
