Description. Male. Head. Brown, antennal flagellomere concolorous with head, scapus and pedicellus slightly paler brown, maxillary palpus pale brown. Eye bridge 3 facets wide. Face with 6–11 scattered longer and shorter setae. Clypeus with 2–3 setae. Maxillary palpus with 3 palpomeres; palpomere 3 longer than palpomere 1, palpomere 2 shortest; palpomere 1 with 1–4 setae, with a dorsal patch of sensilla; Antennal flagellomeres rather smooth, flagellomere 4 ( Fig. 13 A) 1.95–2.25x as long as wide, the neck shorter than broad, the longest setae shorter than the width of flagellomere. Thorax. Brown, setae dark. Anterior pronotum with 6–7 strong setae. Episternum 1 with 7–10 setae. Scutum with rather long dorsocentrals, with 2–3 strong laterals, scutellum with 4 longer and some short setae. Wing. Hyalinous. Length 1.8–2.1 mm. Width/length 0.45. Veins distinct. R1/R 0.85. c/ w 0.85 –0.90. r-m and bM subequal in length, both r-m and bM non-setose. Halter pale brown. Legs. Brown, slightly paler than thorax. Coxal setae dark. Apical part of front tibia, Fig. 13 B: tibial organ with pale fine vestiture forming a small demarcated patch. Front tibial spur as long as the tibial width. Claws with teeth. Abdomen. Brown, setae dark. Sternite 8, Fig. 13 C, with a dense group of dark long setae. Hypopygium, Figs 13 D–E. Brown, concolorous with abdomen. Gonocoxa longer than gonostylus, mesial margin with short setae. Gonostylus strongly curved, with the mesial side impressed; with a dense apical vestiture, with 2–3 very slender megasetae, with a short subapical whiplash seta. Tegmen longer than broad, apically roundish, laterally straight, with a sclerotized apical process.

Discussion. In the general form of its gonostylus. Pseudolycoriella villosa resembles P. capillosa , but has narrow subapical megasetae ( Figs 3 and 13 ). Pseudolycoriella villosa also has a longer tegmen, lacks the group of setae at the gonocoxal base but has a group of unusually long setae on sternite 8, lacking in P. capillosa and in all other Australasian species of Pseudolycoriella . In some preparations, sternite 8 has shifted over the intercoxal area of the hypopygium, giving a false impression of a setose intercoxal lobe.

Etymology. The name is Latin, villosa , hairy, referring to setose sternite 8.
