Diagnosis: Head lacking vertexal foveae; antennae 10-segmented with 2-segmented antennal club; A4, A5, A6, A7, A8 and A10 unmodified, A6 and A7 asymmetrical and subequal in size, A8 shortened, about half length of A7, A9 greatly prolonged and enlarged, slightly impressed subapically at ventral side, A10 largest and conical, about 1.4 × longer than A9, slightly impressed at base in ventral view. Abdominal ventrite 2 with pair of minute discal protuberances, inserted with slightly curved small apical setae; ventrite 6 unknown. Protrochanters, protibiae and mesotibiae unmodified.

Description: Body length 1.57 mm; body colour reddish brown with lighter coloured legs. Head wider than long; frons slightly narrowed at end, about two-fifths width of head at eye level; eyes moderately developed, with about 28 facets; lacking vertexal foveae; antennal tubercles barely visible; postantennal notches weakly demarcated; postantennal cavities large, slightly shorter than antennal tubercles in dorsal view; antennae 10-segmented with 2- segmented antennal club; A4, A5, A6, A7, A8 and A10 unmodified, A6 and A7 asymmetrical and subequal in size, A8 shortened, about half length of A7, A9 greatly prolonged and enlarged, slightly impressed subapically at ventral side, A10 largest and conical, about 1.4 × longer than A9, slightly impressed at base in ventral view. Pronotum as long as wide, about as wide as head at eye level; lacking lateral antebasal foveae. Elytra slightly wider than long, widest at apical two-thirds; humeral calli weak; sutural stria distinctively extending from base to apex. Abdomen with tergite 1 about 1.7 × longer than tergite 2; ventrite 2 with pair of minute discal protuberances, inserted with slightly curved small apical setae; ventrite 6 unknown. Legs with protrochanters, protibiae and mesotibiae un- modified. Aedeagus about 0.26 mm long, with long and stout parameres curved towards each other at apex, bent downwards in lateral view, widest near middle, with pair of long subapical setae and four pairs of short apical setae; median lobe lacking sclerites, with pair of fork-shaped laminae near base, lateral apical margin of median lobe sclerotized.

Comments: This is the only species within the subgenus Byraxis with protrochanters lacking a ventral spine ( Fig. 23D View FIGURE 23 ).

Etymology: This species is named after one of its collectors, Robert Hoare, lepidopterist at NZAC and assisted us with naming our new species.
