Type depository: BMNH LT ♂, 6 PLT.<b> NEW SYNONYMY</b>.</p> <p> <b> Type locality:</b> [AK] Auckland.</p> <p> <b> Type depository:</b> BMNH LT ♂, 3 PLT.</p> <p> <b> Diagnosis:</b> Head with vertexal foveae punctiform; antennae 10-segmented with 2-segmented antennal club; A4, A5, A6, A7 and A8 unmodified, A9 narrowed at base, truncate at apex, with outside surface strongly polished and slightly concave, A10 bean-shaped, strongly concave at lateral side. Abdominal ventrite 2 with pair of slightly prominent discal protuberances, inserted with slightly curved apical setae; ventrite 6 with pair of long median struts, about two-thirds of ventral length, slightly curved inwards at apex. Protrochanters with long ventral spine, about as long as protrochanteral width; protibiae and mesotibiae unmodified.</p> <p> <b> Redescription:</b> Body length 2.00– 2.14 mm; body colour reddish brown to dark brown with lighter coloured elytra and legs.<b> Head</b> about as long as wide; frons slightly narrowed at end, about three-fifths width of head at eye level; eyes well developed, with about 38 facets; vertexal foveae punctiform; antennal tubercles weak; postantennal notches punctiform; postantennal cavities long and narrow, slightly shorter than antennal tubercles in dorsal view; antennae 10-segmented with 2-segmented antennal club; A4, A5, A6, A7 and A8 unmodified, A9 narrowed at base, truncate at apex, with outside surface strongly polished and slightly concave, A10 bean-shaped, strongly concave at lateral side.<b> Pronotum</b> longer than wide, slightly narrower than head at eye level; lateral antebasal foveae punctiform.<b> Elytra</b> about as long as wide, widest at apical three-fourths; humeral calli barely visible; sutural stria distinctively extending from base to apex.<b> Abdomen</b> with tergite 1 about twice length of tergite 2; ventrite 2 with pair of slightly prominent discal protuberances, inserted with slightly curved apical setae; ventrite 6 with pair of long median struts, about two-thirds of ventral length, slightly curved inwards at apex.<b> Legs</b> with protrochanters modified with long ventral spine, about as long as protrochanteral width; protibiae and mesotibiae unmodified.<b> Aedeagus</b> about 0.36 mm long, with slender parameres, with four pairs of apical setae; median lobe with single stout and long sclerite, slightly bent and widest near middle in dorsal view.</p> <p> <b> Comments:</b> The lectotype and two paralectotypes of<i> E</i>. (<i> B.</i>)<i> munroi</i> were compared with the lectotype and one paralectotype of<i> E</i>. (<i> B.</i>)<i> dispar</i>, and were found to represent a single species by having identical antennal modifica- tions; the former name is here treated as the junior synonym. This species is distinguished from other<i> Eupines</i> by its modified A10 and the median lobe containing a single sclerite ( Figs. 15 B–J).</p> <p> <b> Distribution:</b> North Island. AK, WO, TK.
