Etymology. This species is named for the collector of the holotype, John C. Watt.

Diagnosis. This species can be distinguished from the other species of the baiknami speciesgroup by the following combination of characters: smaller body, length 2.2–2.5 mm; antennomeres 4–10 with tubercles; male head bluntly triangular, ventral surface of head with short carinae from posterior point of eyes; male fore tibia with semicircular depression and mid-tibia bent; shape of antennomeres and genitalia unique to species.

Description. Length 2.2–2.5 mm. Body brown, antennae and maxillary palpi paler, legs and elytra yellowish brown ( Fig. 15b View Fig ). Head: Male head as long as wide, widest across eyes, ventral surface with short carina from hind point of eyes, as long as eye ( Fig. 16h View Fig ). Antennomere 1 approximately 2 times longer than wide, 2–3 transverse, 4 longer than wide, 5 subquadrate, 9–10 transverse, 4–10 with tubercles. Frontal sulcus deep, reaching beyond eye from frontal fovea ( Fig. 16h View Fig ). Anterior frontal fovea round ( Fig. 16h View Fig ). Posterior frontal fovea elongate ( Fig. 16h View Fig ). Eye large and prominent, one-half length of temple in male ( Fig. 16h View Fig ), one-third length of temple in female. Thorax: Prosternum as long as wide, widest at midpoint. Male fore tibia with semicircular depression. Elytra rectangular ( Fig. 15b View Fig ). Meso- and metathorax trapezoidal, longer than wide. Hind wings well-developed. Male mid-tibia bent. Abdomen: Tergite IV with pair of transverse patches of microtrichia reaching middle. Aedeagus: Median lobe divided deeply ( Fig. 16b View Fig ). Phallobase of median lobe asymmetrical and triangular ( Fig. 16b View Fig ). Parameres asymmetrical, right paramere larger than left ( Fig. 16b View Fig ).

Distribution. Auckland, Northland, Waikato ( Fig. 17 View Fig : triangles).

Habitat. Most specimens of this species were collected using window, flight intercept, and pitfall traps or by sifting leaf and log litter in kauri, broadleaf, hardwood, and podocarp forests. A few specimens were found at the bases of Metrosideros robusta A. Cunn. (Myrtaceae) and tree ferns.
