Redescription. Male. Head. Head capsule brown. Eye bridge three facets wide, two facets at margin. Scape and pedicel slightly paler than the flagellomeres; fourth flagellomere 3.1–3.4 times longer than wide ( Fig. 4 ); necks of flagellomeres well differentiated; surface of flagellomeres rough, sparsely scattered with long setae arising from slight elevations, setae 1.5 times as long as flagellomere width; sensilla of two different lengths present, small ones and longer, curved sensilla. Maxillary palp long and three-segmented, first palpomere usually as long as third, second one shortest; first palpomere with an inconspicuous patch of sensilla and two to five bristles, one of these bristles longer and more robust, located on the outer side. Prefrons and clypeus bulging. Thorax brown, paler than head. Posterior pronotum bare. Anterior pronotum with three to five setae. Episternum 1 with three to eight setae. Mesonotum with four to five robust lateral bristles; row of dorsocentral bristles well developed. Scutellum with four robust bristles and several minor setae. Katepisternum slightly longer than high. Wing. Length 1.7–2.1 mm; width/length ratio 0.35–0.39. Membrane transparent and without macrotrichia, anal area present; all posterior veins distinct, stem of M weakest, R 5 without macrotrichia on ventral side; bM and r-m bare; R 1 0.6–0.8 times as long as R; c/w ratio 0.61–0.72; r-m 0.7–0.9 as long as bM. Haltere short; knob as long as shaft. Legs pale, trochanter slightly darkened. Tibial organ surrounded by a circular border and wider than half width of tibial apex; tibial organ consists of an irregular transverse row of bristles and some bristles above the row. Fore tibia without robust bristles among the vestiture. Mid tibia mostly without robust bristles, exceptionally four specimens with one bristle among vestiture. Hind tibia with ten to 16 very robust bristles arranged in a longitudinal, posteriodorsal row; on posterior side of hind tibia one to six robust bristles among the vestiture. All tibial spurs equal in length. Claws with robust teeth, arranged in decreasing size. Abdomen brown with dark setae. Hypopygium ( Fig. 14 ). Gonocoxites wider than long, inner side of gonocoxites basally widely separated. Gonostylus short, and curved, 1.9–2.4 times longer than wide, apically with a large inner cavity, dorsal inner margin also apically constricted; two robust spines present, the dorsal one located on a basal lobe and unusually straight; one long whip-lash hair is located on the ventral apex of the gonostylus. Tegmen broader than long, apicolaterally with two strongly sclerotized lobes, apex roundish and surrounded by a thin sclerotized margin, only exceptionally with a small membranous area; parameral apodeme short and robust. Area of teeth consists of nine to 20 small teeth. Ejaculatory apodeme dark, of medium length and narrow; base of ejaculatory apodeme pale, lyre-shaped e.g. broadly fused basally with two medium long branches. Posterior portion of gonocoxal apodeme of medium size and brown, medially connected by a slender bridge. Anterior portion of gonocoxal apodeme long and broad.

Body size: 1.9–2.5 mm.

Female. Unknown.

Genetic distances. The maximum p-distance between all nine available COI sequences is 3.07%. The nearest neighbour is Psl. mahanga , diverging by a minimum of 7.14%. The maximum p-distance between all five available 28S sequences is 0.12%. The nearest neighbour is Psl. mahanga , diverging by a minimum of 0.06%.

Distribution. New Zealand.

Remarks. One paratype of Psl. bispina , deposited in the NZAC, was not investigated in the present study and its species affiliation has not been revised. Nevertheless, it has to be mentioned, that it is labelled with another locality than published in Mohrig & Jaschhof (1999). According to New Zealand Arthropod Collection (2019) the collection data are: one paratype, North Island, Taupo, Hauhungaroa Range, 5 km SW Tihoi, podocarp forest, sweep net, 21.12.1992, leg. Jaschhof (NZAC, NZAC02016076).
