Etymology. This species is named after the type locality, Tennyson Inlet, Marlborough Sounds.

Diagnosis. This species can be distinguished from the other species of the misella species-group by the following combination of characters: body larger, length 2.7–2.9 mm; male antennomeres 4–10 longer than wide and enlarged; eye larger, approximately one-half length of temple; male abdominal ventrites V–VI with round medial process, VII with rounded concave process medially; shape of antennomeres and genitalia unique to species.

Description of Male. Length 2.7–2.9 mm. Body reddish brown, antennae, legs, maxillary palpi, and elytra paler ( Fig. 58m ). Head: Round, as long as wide, widest across eyes ( Fig. 58m ). Antennomere 1 approximately 1.5 times longer than wide, 2–8 longer than wide, 9–10 subquadrate, 4–10 enlarged, 4–11 bearing tubercles. Frontal rostrum rectangular, lobes continuous. Frontal sulcus reaching midpoint of eye. Posterior frontal fovea teardropshaped. Eye prominent, approximately one-half length of temple. Thorax: Prosternum as long as wide, widest at midpoint. Elytra rectangular ( Fig. 58m ). Meso- and metathorax trapezoidal, longer than wide. Abdomen: Tergite IV with pair of transverse patches of microtrichia. Male abdominal ventrites V–VI with round medial process, VII with rounded concave process medially. Aedeagus: Apical lobe of genitalia rectangular, vertically with membranous tube ( Fig. 59n ). Phallobase of median lobe symmetrical and rounded ( Fig. 59n ). Parameres asymmetrical, right longer than left, with setae apically ( Fig. 59n ).

Distribution. Marlborough Sounds, Westland ( Fig. 63 : white circle).
