Diagnosis. This species can be distinguished from the other species of the furcata speciesgroup by the following combination of characters: antennomeres 4–6 longer than wide; frontal sulcus inverted Y-shaped; eye prominent, approximately one-third length of temple; male abdominal ventrites V–VI weakly depressed medially and surrounded by dense setae; shape of genitalia unique to species.

Redescription. Length 1.8–2.1 mm. Body reddish brown, antennae, legs, maxillary palpi, and elytra paler ( Fig. 52a View Fig ). Head: Weakly transverse, widest across eyes ( Fig. 52a View Fig ). Ventral surface of male head with inverted triangular process bearing dense setae behind mouthparts. Antennomere 1 approximately 1.5 times longer than wide, 2 longer than wide, 3 subquadrate, 4–6 longer than wide, 7–10 subquadrate. Frontal sulcus inverted Y-shaped. Anterior frontal fovea rectangular covered by frontal rostrum, posterior frontal fovea absent. Eye prominent, approximately one-third length of temple. Thorax: Prosternum as long as wide, widest at midpoint. Elytra rectangular ( Fig. 52a View Fig ). Meso- and metathorax trapezoidal, longer than wide. Abdomen: Tergite IV with pair of transverse patches of microtrichia reaching middle. Male abdominal ventrites V–VI weakly depressed on middle with dense setae. Aedeagus: Median lobe of genitalia broader with hook-shaped lobe at apex ( Fig. 52g View Fig ). Phallobase of median lobe symmetrical and rounded ( Fig. 52g View Fig ). Parameres symmetrical with serrate outer edge of apical lobe and setae inside ( Fig. 52g View Fig ).

Type Locality. Belgrove , near Nelson, New Zealand .

Distribution. Nelson, Marlborough Sounds ( Fig. 53 View Fig : black circles).

Habitat. Specimens of this species were collected using flight intercept and window traps or by sifting leaf litter in podocarp or Nothofagus forests.
