Description. Male. Head. Brown, antenna concolorous with face, maxillary palpus pale brown. Eye bridge 3–4 facets wide. Face with 6–8 dark long setae. Clypeus non-setose. Mouthparts strongly reduced. Maxillary palpus with one segment, with 3–4 pointed setae, with a large dorsal patch of sensilla. Antenna short, antennal flagellomeres laterally flattened, asymmetrical in relation to their necks, frontal part larger; densely setose, setae curved, body of 4th flagellomere 1.55–2.1x as long as wide, the longest setae much shorter than the width of the flagellomere, neck shorter than wide. Thorax. Brown and unicolorous; setae dark. Anterior pronotum with 2–4 setae. Proepisternum with 1–6 setae. Scutellum with 2 long and many short setae. Wing, Fig 2 F View FIGURE 2 . Fumose. Length 1.9–2.0 mm. Width/length 0.50–0.55. Anal lobe rather small. Hind margin with dorsal and ventral setae only. Veins distinct. R1/R 1.50–1.90. c/w 0.75–0.80. bM shorter or as long as r-m, stM longer than M-fork, stCu longer than bM. R1 joining c beyond base of M-fork. R1 with dorsal setae only, bM, r-m and StCu non-setose. Haltere pale brown. Legs. Yellow. Fore tibial organ unmodified, with some fine setae. Fore tibial spur longer than the tibial width. Abdomen. Pale brown; setae long, dark, and robust. Hypopygium, Fig. 15 A View FIGURE 15 . Brown, like the abdomen, broad; setae dark. Gonocoxa broad, slightly longer than gonostylus. Gonocoxae fused, ventromedial margin distinct, intergonocoxal area broad and short, microtrichose, broadly non-setose medially. Setosity of gonocoxa long and dense. Apicomedial seta poorly differentiated. Gonostylus elongated, rather wide medially, impressed dorso- and ventromedially, with rather narrow medial lobe, with long and curved apical tooth with a small megaseta attached to its ventral side, with 2 subapical megasetae near the base of the tooth, and 3 on the medial lobe, the megasetae slender and hyalinous, slightly curved. Tegmen nearly semicircular, slightly curved sub-basally, hyalinous but weakly sclerotized basolaterally, with tiny aedeagal teeth. Aedeagal apodeme broad but indistinct.

Female. Unknown.

Discussion. See under Pseudoaerumnosa obovata sp. n.

Etymology. The name is derived from the Latin words juncus, rush, and seta, hair, referring to the very narrow megasetae of the gonostylus.
