Diagnosis
This species is distinguished from the other species of this genus by the following combination of characters: body length 2.3–2.6 mm; eyes one-half lengths of temples (Fig. 1C); antennomeres 2–5 longer than wide, 6–10 subquadrate; median lobe of male genitalia divided, major lobe triangular, minor lobe slightly longer and unequally laterally tuberculate near apex (Fig. 3C); parameres nearly symmetrical, setae present from apices to middle (Fig. 3C).
Redescription
Length 2.3–2.6 mm. Body reddish brown, antennae, legs, maxillary palpi and elytra paler (Fig. 1C). Head round, as long as wide, widest across eyes (Fig. 1C). Antennomere 1 approximately 1.5 times longer than wide, 2–5 longer than wide, 6–10 subquadrate. Eyes one-half lengths of temples. Prosternum as long as wide, widest at apical one-third. Elytra longer than wide (Fig. 1C). Hind wings fully developed. Meso- and metaventrites trapezoidal, longer than wide. Tergite IV with pair of transverse patches of microtrichia reaching middle. Median lobe of genitalia divided, apical lobe triangular, minor lobe slightly longer covered with tubercles (Fig. 3C). Phallobase symmetrical and rounded (Fig. 3C). Parameres symmetrical, setae present from apices to middle (Fig. 3C).
Type locality
Timaru (SC), New Zealand.
Distribution
Mackenzie (MK), South Canterbury (SC) (Fig. 4: black squares).
Habitat
Specimens were collected by soil washing and sifting moss litter in broadleaf or podocarp forests.
