Diagnosis

For complete description, see Balke (1998[6]: 326). Beetle small to medium-sized: TL-H 3.05–3.9 mm, oblong-oval; dorsally uniformly reddish to dark brown or with paler head and sides of pronotum; shiny, with very fine to distinct punctation and usually weakly impressed microreticulation; pronotum with distinct lateral bead (Fig. 16); male protarsomere 4 with anterolateral seta very long and thin, evenly curved, smaller than more laterally situated large seta; male protarsomere 5 ventrally with anterior band of more than 50 and posterior row of 8 relatively long setae (Fig. 22D); median lobe simple, evenly attenuated to broadly pointed apex in lateral and ventral views; paramere very slightly concave on dorsal side and with long, dense, thin setae, situated along dorsal margin; proximal setae longer that subdistal, more distinct (Fig. 22A–C).

Variability

The species shows variability in size, colouration, how strongly impressed dorsal punctation and, more seldom, microreticulation, and slightly in shape of the apex of the median lobe (Fig. 24).

Affinities

From the species co-occurring in the same area (E. craterensis Shaverdo & Balke, 2014, E. damantiensis (Balke, 1998), E. hintelmannae (Shaverdo, Sagata & Balke, 2005), E. sima, E. kobau sp. nov. and two species of the E. larsoni group), E. bacchusi can be distinguished by its reddish dorsal colouration and shape and setation of the median lobe and paramere. The most similar (in body size and form and colouration) to E. bacchusi are E. warasera sp. nov. and E. haia sp. nov., which occur with it. Only males of these species can be clearly separated by shape and setation of the median lobe and paramere; and therefore, dorsal setae of the paramere are important: in E. bacchusi, proximal setae longer that subdistal, more distinct. For the affinities within the group, see the “Key”.

Distribution

Papua New Guinea: Madang, Simbu, Eastern Highlands, Morobe and Gulf Provinces (Fig. 25). This is one of the most abundant species in the region.
