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). Head: Weakly transverse, widest across eyes (Fig. 52a). 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). 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). Phallobase of median lobe symmetrical and rounded (Fig. 52g). Parameres symmetrical with serrate outer edge of apical lobe and setae inside (Fig. 52g).

Type Locality. Belgrove, near Nelson, New Zealand .

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