Specific epithet. The specific epithet honors the surname of Richard A.B. Leschen, coleopterist of Landcare Research and Curator of the New Zealand Arthropod Collection, who loaned the specimens of Anillina under his care for this study. Type locality. New Zealand , South Island , Southland , Waikaia Forest Conservation area . Recognition. Adults of this species ( Fig. 11 H) are distinguished from other congeners by the characters listed in the species key. Description. Size. Medium to large for genus (SBL range 1.72–1.98 mm , mean 1.84± 0.080 mm , n=14). Habitus. Body form slightly convex, ovoid, moderately elongate (WE/SBL 0.37±0.014), head of moderate width for genus compared to pronotum (WH/WPm 0.72±0.015), pronotum rather narrow in comparison to elytra (WPm/WE 0.71±0.017). Color. Body color rufotestaceous, appendages testaceous. Prothorax. Pronotum slightly long (LP/LE 0.40±0.009) and moderately elongate (WPm/LP 1.28±0.031), with lateral margins rectilinear constricted posteriorly (WPm/WPp 1.52±0.070). Width between anterior angles moderately greater than between posterior angles (WPa/WPp 1.15±0.045). Elytra. Slightly depressed along suture, comparatively long (LE/SBL 0.53±0.012) and moderately wide (WE/ LE 0.69±0.019). Lateral margins slightly divergent at basal third, subparallel at middle and evenly rounded to apex in apical third. Male genitalia. Median lobe ( Fig. 13 E) with straight ventral margin and enlarged apex in dorsal projection. Sclerites of internal sac sclerotized, unequal in length, with long, thick ventral and short, narrow dorsal branches, united basally, almost equals to the half of the distance between apical and basal orifices. Left paramere with long apical constriction ( Fig. 13 G). Ring sclerite without visible handle ( Fig. 14 I). Female internal genitalia. Goncoxite 2 with short ensiform setae ( Fig. 15 H). Spermatheca sclerotized, gigantic, elongate and curved, with two compartments ( Fig. 17 B). Spermathecal duct short and with few coils. Attachments of spermathecal duct and gland to spermatheca at a moderate distance from each other. Geographical distribution. This species is known from several localities in the Waikaia Forest at the upper course of the Waikaia River of Southland ( Fig. 18 B, red triangles). Way of life. Specimens were collected from soil in a beech ( Nothofagus ) forest. Relationships. Males of this species are distinct from those of other members of subgenus in the structure of the median lobe. Hypertrophy of the apex of male median lobe and great increase in the size of spermatheca are shared with members of Z. carltoni . Males of Z. lescheni are also similar to those of the interior Z. montivagus and coastal Z. brouni in the shape of round sclerite.. Based on the latter similarity, I suggest that Z. lescheni shares a common ancestry with the latter two species.
