Etymology. This species is named for one of our lab mates and an enthusiastic supporter of this study, Forest Huval.

Diagnosis. This species can be distinguished from the other species of the misella speciesgroup by the following combination of characters: size larger, 2.6–2.8 mm; male antennomeres 6–10 enlarged; eye larger, approximately one-half length of temple; male abdominal ventrites V–VI with round medial process, VII with a pair of acute processes; shape of antennomeres and genitalia unique to species; known from Southland.

Description. Length 2.6–2.8 mm. Body brown, antennae, legs, maxillary palpi, and elytra paler ( Fig. 58l ). Head: Round, as long as wide, widest across eyes ( Fig. 58l ). Male antennomere 1 approximately 1.5 times longer than wide, 2–4 longer than wide, 5–10 subquadrate, 6–10 enlarged, 6–11 with tubercles. Female antennomeres 2–7 longer than wide, 8–10 subquadrate, 5–11 with tubercles. Frontal rostrum rectangular, lobes continuous. Frontal sulcus reaching midpoint of eye. Posterior frontal fovea elongate. Eye prominent, approximately one-half length of temple. Thorax: Prosternum as long as wide, widest at midpoint. Elytra subquadrate ( Fig. 58l ). Male meso- and metathorax trapezoidal, as long as wide. Abdomen: Male tergite IV without patches of microtrichia. Male abdominal ventrites V–VI with round medial process, VII with a pair of acute processes. Aedeagus: Apical lobe of genitalia triangular, with membranous tube ( Fig. 59m ). Phallobase of median lobe symmetrical and rounded ( Fig. 59m ). Parameres asymmetrical, right wider than left, with setae apically ( Fig. 59m ).

Distribution. Southland ( Fig. 63 : star).

Habitat. Specimens of this species were collected mostly by sifting leaf litter.
