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, an internal eye notch and fully developed hind wings. It differs from E. nebulosus   and E. tropicus   in having a more elongate and narrow body (more than 1.9 times as long as wide; elytra more than 1.57 times as long as wide) and the apical maxillary palpomere widened and obliquely truncate apically and from E. similis   in having the head at least partly black, the apical maxillary palpomere less strongly expanded, the third antennomere only slightly shorter than the fourth and the terminal antennomere less elongate.

Description. Length: 2.40–2.60 (2.48 ± 0.07) mm; body 1.95–1.96 (1.95) times as long as combined elytral width; greatest depth 0.70–0.71 (0.70) times combined elytral width. Colour of head dark brown but reddish posteriorly; pronotum red; scutellar shield and elytra black; undersurfaces mainly dark brown; legs yellowish-brown. Head 0.89 times as long as wide; distance across eyes 1.45 times as great as distance between them; inner edge of eye with distinct notch. Labrum 0.52 times as long as wide; sides weakly curved and converging to slightly emarginate apex. Antenna about 1.8 times as long as head width; 3rd antennomere 0.88 times as long as 4th; 11th antennomere 1.25 times as long as 10, 1.87 times as long as wide and truncate at apex. Mandibular mola well-developed. Galea about 2.0 times as wide at middle as lacinia, distinctly widened and broadly rounded at apex. Apical maxillary palpomere about 1.75 times as long as wide, widest subapically, obliquely truncate at apex. Apical labial palpomere subulate, 2.00 times as long as wide, with aciculate tip. Pronotum 0.41–0.42 (0.41) times as long as wide; prosternal process narrowly rounded apically. Scutellar shield 0.19 times as wide as pronotum, 0.83 times as long as wide with subacute apex rounded at tip. Elytra 1.66–1.67 (1.66) times as long as combined width and 5.66–5.90 (5.79) times as long as pronotum; elytral punctation and vestiture as in Fig. 82 View FIGURES 73–88 . Hind wings fully developed. Metanepisternum 1.32 times as long as mesepimeron, about 2.64 times as long as wide, asymmetrically quadrate with evenly curved inner edge, slightly sinuate outer edge and oblique apical edge. Metacoxal plate with outer edge about 3.2 times as long as posterior edge, which is minutely emarginate at mesal end. Outer (acute) mesotibial spur in male 0.35 times as long as first mesotarsomere; inner spur 1.24 times as long as outer one, parallel-sided with blunt, cleft apex. Parameres at about middle 1.12 times as wide as penis at same point, not at all curved, apex asymmetrically acute with rounded outer side and straight inner side. Penis gradually narrowed to acute apex extending to parameral apices.

Distribution. Northeastern NSW to northern QLD.

Biology. Specimens have been collected in Malaise traps and in berlesates of sifted log and leaf litter.

Etymology. Derived from the name Lorien, a location in J. R. R. Tolkien’s Lord of the Rings, but also the name of a wildlife refuge near Taree, NSW, where the holotype and some of the paratype specimens were collected.
