Diagnosis

This species is distinguished from the other species of this genus by the following combination of characters: body length 2.2–2.5 mm; eyes large, two-thirds length of temples (Fig. 1B); antennomeres 2–7 longer than wide, 8–10 subquadrate; median lobe of male genitalia divided, minor lobe longer than major lobe and covered with small tubercles (Fig. 3B); parameres symmetrical, setae present from apices to middle (Fig. 3B).

Redescription

Length 2.2–2.5 mm. Body reddish brown, antennae, legs, maxillary palpi and elytra paler (Fig. 1B). Head rectangular, longer than wide, widest across eyes (Fig. 1B). Antennomere 1 approximately 1.5 times longer than wide, 2–7 longer than wide, 8–10 subquadrate. Eyes large and prominent, two-thirds length of temples. Prosternum as long as wide, widest at apical one-third. Elytra longer than wide (Fig. 1B). 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, minor lobe longer than major lobe and covered with small tubercles (Fig. 3B). Phallobase symmetrical and rounded (Fig. 3B). Parameres symmetrical, setae present from apices to middle (Fig. 3B).

Type locality

McClennan’s Bush, near Methven (MC), New Zealand.

Distribution

Dunedin (DN), Fiordland (FD), Mid Canterbury (MC) (Fig. 4: black triangles).

Habitat

Specimens were collected using flight intercept traps, and by soil washing or sifting leaf and wood litter.

Comments

The type specimen of Sagola insueta shares the diagnostic characters of Pseudoexeirarthra colorata. For this reason, we have placed Sagola insueta in synonymy with Pseudoexeirarthra colorata.
