Material studied. Holotype male. TAIWAN, Fushan Botanical Garden , 7–9.V.2018, Malaise trap with light ( MT
3), J. Ševčík & M. Tkoč (in NMPC). Paratypes. TAIWAN, same data as holotype, 7 males (4 in NMPC, 3 in JSL- OUC); same data as previous but Malaise trap ( MT 2) over brook, 7–10.V.2018, 3 males (in MZH) .
DNA sequences. The DNA sequences of COI barcode region taken from two paratypes are deposited in Gen- Bank. The Accession Numbers are provided in Table 1 View TABLE 1 .
Description. Male. Head. Brown, antenna concolorous with face, maxillary palpus pale brown. Eye bridge 2–3 facets wide. Face with 4–7 dark long setae. Clypeus non-setose. Mouthparts strongly reduced. Maxillary palpus with one segment, with 2–3 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 1.9–2.25x as long as wide, the longest setae slightly 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 1–3 setae or non-setose. Scutellum with 2 long and many short setae. Wing. Fumose. Length 2.0– 2.2 mm. Width/length 0.50–0.55. Anal lobe small. Hind margin with dorsal setae only. Veins distinct. R1/R 1.60–2.10. c/w 0.70–0.85. bM as long as or shorter than r-m, stM longer than M-fork, stCu as long as or shorter than bM. R1 joining c before base of M-fork. R1 with dorsal and ventral setae, bM, r-m and StCu non-setose. Haltere pale brown. Legs. Yellow. Fore tibial organ unmodified, with some fine setae. Fore tibial spur as long as the tibial width. Abdomen. Pale brown; setae long, dark, and robust. Hypopygium, Fig. 13 A View FIGURE 13 . Brown, like the abdomen, broad; setae dark. Gonocoxa broad, slightly longer than gonostylus. Gonocoxae fused, ventromedial margin distinct, intergonocoxal area broad and short, non-microtrichose, setose medially. Setosity of gonocoxa long and dense. Apicomedial seta well differentiated. Gonostylus elongated, impressed dorso- and ventromedially, with moderate medial lobe reaching to apical ¼ of gonostylus, with long, narrow, curved apical tooth with a small megaseta attached to its ventral side, with 2 megasetae subapically near the apical tooth, and 3 on the medial lobe, the megasetae slender and hyalinous, slightly curved. Tegmen broader than long, roundish apically, smoothly curved laterally, narrowed above the middle, hyalinous but broadly sclerotized basolaterally, with tiny aedeagal teeth. Aedeagal apodeme moderate with distinct apical fork.
Female. Unknown.
Discussion. Pseudoaerumnosa formosa sp. n. resembles P. annae sp. n. (see under the latter and also under P. tkoci sp. n.).
Etymology. The name is Latin, formosa , beautiful, referring to the elegant curvature of the apical tooth of the gonostylus.
