Material studied. Holotype male. NEW CALEDONIA, Rivière Bleue N.P., (parc 6), rainforest, 20.i.1993, Bonnet de Larbogne, Chazeau & Guilbert (in MNHN). Paratypes. 1 male, same data as holotype (in MNHN), 1 male, Rivière Bleue N.P., 150 m, humid forest on alluvials, Malaise trap, 2.iv –6.v.1987, Bonnet de Larbogne, Chateau & Tillier (in MNHN), 4 males, Vallée de la Coulée, 166°35’E, 22°10’S, 40 m, maquis, 24.x.1985, Bouchet (in MNHN, MZH, SMNH and PWMP).

Description. Male. Head. Brown, antenna with scapus and pedicellus slightly paler brown, maxillary palpus very pale brown. Eye bridge 3 facets wide. Face with 7–11 scattered longer and shorter setae. Clypeus with 1–2 setae. Maxillary palpus with 3 palpomeres; palpomere 1 as long as palpomere 3 or slightly longer, palpomere 2 shortest; palpomere 1 with 1–2 setae, with a dorsal patch of sensilla; surface of antennal flagellomeres rough, flagellomere 4 ( Fig. 11 A) 1.50–1.75x as long as wide, the neck as long as broad, the longest setae shorter than the width of flagellomere. Thorax. Brown, setae pale. Anterior pronotum with 2 setae. Episternum 1 with 3–5 setae. Scutum with short dorsocentrals, with 2–3 stronger laterals, scutellum with two longer and some short setae. Wing. Hyalinous. Length 1.0– 1.1 mm. Width/length 0.45–0.50. Veins indistinct. R1/R 0.50–0.70. c/ w 0.65 –0.80. r-m and bM subequal in length, or bM longer, r-m/bM 0.75–1.0, both r-m and bM non-setose. Halter pale brown, short. Legs. Pale yellowish brown. Coxal setae pale. Apical part of front tibia, Fig. 11 B: tibial organ a shallow bordered depression, with fine pale vestiture forming 2–3 indistinct curved rows. Front tibial spur slightly longer than the tibial width. Claws with teeth. Abdomen. Pale brown, setae pale. Hypopygium, Figs 11 C–D. Brown, concolorous with abdomen. Gonocoxa longer than gonostylus, mesially sparsely setose. Gonostylus slightly curved, evenly broad with the mesial side slightly impressed at medial third; with rather dense apical vestiture, with three curved megasetae, with a slightly elongated subapical whiplash seta. Tegmen apically roundish, laterally unsclerotized, with an indistinct medial process.

Discussion. Pseudolycoriella trispicata and P. tenuis are the only Australasian species with three gonostylar megasetae in a group close to each other ( Figs 9 and 11 ). Pseudolycoriella trispicata differs in having the gonocoxa and gonostylus shorter and wider, the megasetae more curved and the whiplash seta shorter.

Etymology. The name is Latin, trispicata , armed with three spikes, referring to the number of the gonostylar megasetae.
