Paratypes . 2♂♂ North Island , Western Bay of Plenty , Katikati , Te Mania catchment, Malaise trap , 19.09– 27.10.2016 , leg. P.A. Maddison ( SDEI , SDEI-Dipt-0000664 & SDEI-Dipt-0001369) . Description. Male . Head. Head capsule brown, slightly darker than thorax. Eye bridge two to three facets wide. Scape and pedicel pale brown, slightly paler than the flagellum; fourth flagellomere 2.7 times longer than wide (flagella are missing in both paratypes ); necks of flagellomeres well differentiated, bright; surface of flagellomeres rough with deep pits, sensilla of two different lengths, small ones and longer, curved sensilla; setae on the flagellomere as long as flagellomere width, slightly curved. Maxillary palp long and three-segmented, first palpomere is the longest, second is shortest, first palpomere with long sensilla and four to six long bristles, one bristle longer and more robust, located on the outer side. Prefrons and clypeus bulging. Thorax dark brown. Posterior pronotum bare. Anterior pronotum with four to six setae. Episternum 1 with four to seven setae. Mesonotum with four to five robust lateral bristles. Scutellum with two to three robust bristles and several minor setae. Katepisternum as long as high. Wing. Length 2.5–2.7 mm ; width/length ratio 0.38–0.42. Membrane transparent, slightly shaded and without macrotrichia, anal area present; all posterior veins distinct, stem of M weak; apical 40–50% of R 5 with macrotrichia on both ventral and dorsal sides; r-m and bM without macrotrichia; R 1 0.7 times as long as R; c/w ratio 0.74–0.80; r-m 0.7–0.8 as long as bM. Haltere brownish; head of haltere as long as shaft. Legs brownish, slightly paler than thorax. Tibial organ surrounded by a circular border and as wide as half width of tibial apex; tibial organ arranged in an irregular row. Front tibia without or with one robust bristle among vestiture. Mid tibia with one or two slightly robust bristles. Posteriodorsal row of bristles extending two-thirds of apical tibia length. All tibial spurs equal in length. Claws with robust teeth. Abdomen pale brown, paler than thorax; with long, dark setae. Hypopygium ( Fig. 47 ). Gonocoxites wider than long, inner side of gonocoxites with several medium sized setae, outer side with long setae; ventral, inner side of gonocoxites basally separated. Gonostylus swollen, 2.4–2.5 times longer than wide; apex well differentiated, bent inwards, apical cavity conspicuous without microtrichia; one spine on the gonostylus, located subapically, and one long whip-lash hair. Tegmen of the typical ground plan of the Psl . jejuna complex, onion-shaped and roundish; the dorsal folds strikingly developed; parameral apodemes basally strongly sclerotized, apically broad. Area of teeth absent. Ejaculatory apodeme short and dark; base of ejaculatory apodeme pale yellow, v-shaped. Posterior portion of gonocoxal apodeme of medium size and brown, medially joined. Anterior portion of gonocoxal apodeme medium long and dark brown. Body size : 2.6–2.9 mm . Female . Unknown. Genetic distances. All three available COI sequences are identical and do not show any pairwise distance. The nearest neighbour is Psl . tewaipounamu , diverging by a minimum of 5.84%. Both available 28S sequences are identical. The nearest neighbour is Psl . tewaipounamu , diverging by a minimum of 0.17%. Etymology. This new species is named after Peter A. Maddison to acknowledge his valuable collection work. Distribution. New Zealand . Discussion. Among all species of the Psl . jejuna complex Psl . maddisoni and Psl . whakahara have the broadest gonostyli. However due to the hunchbacked shape of the gonostylus Psl . maddisoni is easy to identify.
