( Figs 26–27 , 50 , 64 , 88 , 136 ) 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. bicolor , E. bicolorellus , E. limitaris and E. protibialis in that all surfaces are yellowish-brown to red- dish-brown, without the contrasting red pronotum and black elytra. It differs from E. dorrigo in having the apical antennomere much shorter and broader, less than 1.4 times as long as wide, the apical maxillary palpomere gradually narrowed apically with its aciculate tip centrally located, parameres not outwardly bowed and length usually greater than 2.00 mm, and from E. brindabellae in having the apical antennomere less than 1.5 times as long as wide, the third antennomere equal in length to the fourth, the sides of the elytra less strongly curved, the upper surfaces very slightly curved in lateral view and the colour mainly yellowish-brown with legs and antennae yellow. Description Length 1.80–2.30 (2.06 ± 0.18, n = 10) mm; body 1.79–1.97 (1.85) times as long as combined elytral width; greatest depth 0.59–0.69 (0.64) times elytral width. Colour of dorsal and ventral surfaces primarily yellowish-brown; legs and antennae yellow. Head 0.96 times as long as wide; distance across eyes 1.49 times distance between them; inner edge of eye without notch. Labrum 0.50 times as long as wide; sides weakly converging; apex slightly emarginate. Antenna about 1.7 times as long as head width behind eyes; 3rd antennomere equal in length to 4th; 11th antennomere 1.33 times as long as 10th, 1.90 times as long as wide, with apex broadly rounded. Mandibular mola reduced. Galea about as wide as lacinia and not widened at apex. Apical maxillary palpomere subulate, 2.00 times as long as wide, with very short aciculate tip. Apical labial palpomere subulate, 2.25 times as long as wide, widest at middle, with long aciculate tip. Pronotum 0.40–0.48 (0.45) times as long as wide; prosternal process narrowly rounded at apex. Scutellar shield 0.23 times as wide as pronotum, 0.8 times as long as wide, acute at apex. Elytra 1.43–1.58 (1.49) times as long as combined width and 3.78–4.45 (4.11) times as long as pronotum; elytral punctation and vestiture as in Fig. 88 . Hind wings absent. Metanepisternum 0.73 times as long as mesepimeron, about 1.22 times as long as wide, subtriangular with moderately straight anterior and inner edges and curved outer edge. Metacoxal plate with outer edge about 3.5 times as long as posterior edge, which is weakly biemarginate. Outer (acute) mesotibial spur in male 0.57 times as long as first mesotarsomere; inner spur 0.83 times as long as outer spur, parallel-sided with a blunt, cleft apex. Meso- and metapretarsal claws simple and without accessory lobes. Parameres at about middle 1.5 times as wide as penis at same point; inner edge of each straight almost to apex, outer edge straight to subapex, then distinctly curved to narrowly rounded apex. Penis gradually narrowing to subapex, then abruptly narrowed to subacute apex. Types: Holotype , ♁: “ 41.11S 140.00E TAS, Mt. Michael , 740m , 26 Nov. 1989 , pyrethrin knockdown, tree 1, Tube 187, R.

Specimens collected primarily in Berlese samples from leaf litter, but some were taken in flight intercept window/trough traps, pitfall traps, yellow pans and by pyrethrin fogging. Etymology. Derived from the name of the island of Tasmania .
