Etymology

This species is named after Mr. Peter Hlaváč, world pselaphine beetle specialist, and an enthusiastic supporter of this study.

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 large, as long as temples (Fig. 1I); antennomere 2 longer than wide, 3 subquadrate, 4 longer than wide, 5–8 subquadrate, 9–10 weakly transverse; median lobe of male genitalia divided, major lobe truncate and broadest at apex, minor lobe longer with small tubercles (Fig. 3I); parameres nearly symmetrical, right paramere slightly longer than left with setae present on mesal margins in apical two-thirds (Fig. 3I).

Description

Length 2.3–2.6 mm. Body reddish brown, antennae, legs, maxillary palpi and elytra paler (Fig. 1I). Head round, as long as wide, widest across eyes (Fig. 1I). Antennomere 1 approximately 1.5 times longer than wide, 2 longer than wide, 3 subquadrate, 4 longer than wide, 5–8 subquadrate, 9–10 weakly transverse. Eyes large and prominent, as long as temples. Prosternum as long as wide, widest at one-third length. Elytra longer than wide (Fig. 1I). Hind wings fully developed. Meso- metaventrites trapezoidal, longer than wide. Tergite IV with pair of transverse patches of microtrichia reaching middle. Median lobe of genitalia divided, major lobe truncate and broadest at apex, minor lobe longer with small tubercles (Fig. 3I). Phallobase symmetrical and rounded (Fig. 3I). Parameres nearly symmetrical, right paramere slightly longer than left with setae present on mesal margins in apical two-thirds (Fig. 3I).

Distribution

Dunedin (DN), Southland (SL) (Fig. 6: black circles).

Habitat

Specimens were collected mostly by soil washing in Nothofagus and broadleaf forests.
