Type locality: [AK] Hunua Range, Maketu.

Type depository: BMNH LT ♂, 3 PLT ; NZAC 14 About NZAC PLT .

Diagnosis: Head with vertexal foveae punctiform; antennae 10-segmented with 2-segmented antennal club; A4, A5, A6, A7 and A8 unmodified, A9 boot-shaped with curved basal spine, A10 bean-shaped, truncate at base in dorsal view, with bi-excavation in ventral view. Abdominal ventrite 2 with pair of large discal protuberances, inserted with strongly curved apical setae; ventrite 6 with pair of median struts, slightly shorter than one-fourth of ventral length. Protrochanters with long ventral spine, about four-sevenths of protrochanteral width; protibiae and mesotibiae unmodified.

Redescription: Body length 1.45–1.56 mm; body colour reddish brown to dark brown with lighter coloured elytra and legs. Head slightly wider than long; frons slightly narrowed at end, about two-thirds width of head at eye level; eyes prominent, with about 38 facets; vertexal foveae punctiform; antennal tubercles weak; postantennal notches weak; postantennal cavities well developed, about two-thirds length of antennal tubercles in dorsal view; antennae 10-segmented with 2-segmented antennal club; A4, A5, A6, A7 and A8 unmodified, A9 boot-shaped with curved basal spine, A10 bean-shaped, truncate at base in dorsal view, with bi-excavation in ventral view. Pronotum as long as wide, about as wide as head at eye level; lacking lateral antebasal foveae. Elytra as long as wide, widest at apical two-thirds; humeral calli vaguely visible; sutural stria distinctively extending from base to apex. Abdomen with tergite 1 about twice length of tergite 2; ventrite 2 with pair of large discal protuberances, inserted with strongly curved apical setae; ventrite 6 with pair of median struts, slightly shorter than one-fourth of ventral length. Legs with protrochanters modified with long ventral spine, about four-sevenths of protrochanteral width; protibiae and mesotibiae unmodified. Aedeagus about 0.32 mm long, with parameres elongate and thick, curved downwards; median lobe with two long sclerites, narrower than parameres in dorsal view, both bent inwards subapically in dorsal view, with left one longer than right one.

Comments: This species is most similar to E. (B.) monstrosa by having similar modifications of A9 and A10 and can be separated by A10 lacking a small internal hook at the apex ( Fig. 11B View FIGURE 11 ).
