Description. Male. Head. Brown, antenna unicolorous, paler brown, maxillary palpus very pale brown. Eye bridge 2–3 facets wide. Face with 9–22 scattered longer and shorter setae. Clypeus with 4–6 setae. Maxillary palpus with 3 palpomeres; palpomere 1 as long as palpomere 3, palpomere 2 shortest; palpomere 1 with 2–5 setae, with a dorsal patch of sensilla; surface of antennal flagellomeres rough, flagellomere 4 ( Fig. 3 A) 1.8–3.5x as long as wide, the neck longer than broad, the longest setae longer than the width of flagellomere. Thorax. Brown, setae pale. Anterior pronotum with 2–6 setae. Episternum 1 with 1–6 setae. Scutum with short dorsocentrals, with 2–3 stronger laterals, scutellum with longer and shorter fine setae. Wing. Hyalinous. Length 1.3–1.8 mm. Width/length 0.40–0.45. Veins distinct. R1/R 0.50–0.55. c/ w 0.65 –0.80. r-m and bM subequal in length, both r-m and bM nonsetose. Halter pale brown. Legs. Pale yellowish brown. Coxal setae pale. Apical part of front tibia, Fig. 3 B: tibial organ with fine vestiture in curved row. Front tibial spur slightly shorter than the tibial width. Claws without teeth. Abdomen. Pale brown, setae pale and fine. Hypopygium, Figs 3 C–E. Brown, concolorous with abdomen. Gonocoxa longer than gonostylus, mesial margin with a dense basal setosity. Gonostylus strongly curved, with the mesial side impressed; with a dense apical vestiture, without megasetae, with a long subapical whiplash seta. Tegmen apically roundish, laterally weakly sclerotized, with a broad apical process, not visible in all specimens.

Discussion. Pseudolycoriella capillosa is similar to P. pallidula and P. spicata in having a densely setose area at the basal part of the gonocoxa ( Figs 3 , 5 and 8 ), but is distinguished from these and all other Australasian species of Pseudolycoriella in lacking gonostylar megasetae. Pseudolycoriella pallidula and P. s p i c a t a both have a group of mesial megasetae on the gonostylus, but differ in P. pallidula having a distinct setose intercoxal lobe of the hypopygium. Both a densely setose area at the base of gonocoxa and an intercoxal lobe of the hypopygium are absent in other species of Australasian Pseudolycoriella , but present in some Neotropical ( Mohrig 2003, Mohrig et al. 2004) and Afrotropical species ( Rudzinski 2003).

Etymology. The name is Latin, capillosa , hairy, referring to the setose area on the basal part of the gonocoxa.
