Type locality: [ MC] Broken River , Canterbury .

Type depository: BMNH HT ♂

Diagnosis: Head with vertexal foveae punctiform; antennae 10-segmented with 2-segmented antennal club; A4, A6, A7, A8 and A10 unmodified, A5 large and asymmetrical, bean-shaped, lateral margin laminate and curved, forming bowl-shaped excavation, A7 asymmetrical, A8 disc-shaped, A9 large and asymmetrical, slightly shorter than A10, inner side strongly excavated in dorsal view, with upper margin laminate and extended, forming gulfshaped structure, A10 largest and conical, about 1.2 × longer than A9. Abdominal ventrite 2 with pair of large discal protuberances slightly curving towards each other, inserted with strongly curved small apical setae; ventrite 6 with pair of short and acute median struts, about one-fourth of ventral length. Legs with protrochanters modified with small ventral spine, about one-third of protrochanteral width; protibiae and mesotibiae unmodified. Protrochanters with small ventral spine, about one-third of protrochanteral width; protibiae and mesotibiae unmodified.

Redescription: Body length 1.58–1.60 mm; body colour dark brown with lighter coloured legs. Head about as long as wide, frons slightly narrowed at end, about half width of head at eye level; eyes moderately developed, with about 29 facets; vertexal foveae punctiform; antennal tubercles weak; lacking postantennal notches; postantennal cavities medium-sized, about half length of antennal tubercles in dorsal view; antennae 10-segmented with 2-segmented antennal club; A4, A6, A7, A8 and A10 unmodified, A5 large and asymmetrical, bean-shaped, lateral margin laminate and curved, forming bowl-shaped excavation, A7 asymmetrical, A8 disc-shaped, A9 large and asymmetrical, slightly shorter than A10, inner side strongly excavated in dorsal view, with upper margin laminate and extended, forming gulf-shaped structure, A10 largest and conical, about 1.2 × longer than A9. Pronotum about as long as wide, wider than head at eye level; lacking lateral antebasal foveae. Elytra as long as wide, widest at apical two-thirds; humeral calli distinctively prominent; sutural stria distinctively extending from base to apex. Abdomen with tergite 1 about 1.8 × longer than tergite 2; ventrite 2 with pair of large discal protuberances slightly curving towards each other, inserted with strongly curved small apical setae; ventrite 6 with pair of short and acute median struts, about one-fourth of ventral length. Legs with protrochanters modified with small ventral spine, about one-third of protrochanteral width; protibiae and mesotibiae unmodified. Aedeagus about 0.32 mm long, with sinuate parameres long and stout, widest near basal one-fourth, apex strongly bent downwards and twisted in lateral view, with three short apical setae; median lobe with two short sclerites, much shorter and narrower than parameres in dorsal view, left one distinctively curved outwards, right one point inwards.

Comments: The special antennal modifications ( Figs. 29 View FIGURE 29 B–D) can easily separate this species from all congeners.
