Description. Male. Head. Brown, antenna concolorous with face, maxillary palpus pale brown. Eye bridge 2–3 facets wide. Face with 6–7 long dark setae (or non-setose). Clypeus non-setose. Mouthparts strongly reduced. Maxillary palpus with one segment, with 4–6 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 1.65–1.85x 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 1–4 setae. Proepisternum with 1–4 setae or non-setose. Scutellum with 4 long and many short setae. Wing. Fumose. Length 2.3–2.5 mm. Width/length 0.50. Anal lobe moderate. Hind margin with dorsal setae only. Veins distinct. R1/R 1.35–1.80. c/w 0.80–0.85. bM shorter than r-m, stM longer than M-fork, stCu shorter or longer than bM. R1 joining c before base of M-fork. R1 with dorsal and ventral setae, bM and StCu non-setose, r-m non-setose or 1–2 setae. 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. 6 A View FIGURE 6 . Brown, like the abdomen, broad. Gonocoxa rather narrow, slightly longer than gonostylus. Gonocoxae fused, ventromedial margin roundish and basally 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 a large apical tooth with a small megaseta inside, with a medial lobe, with 2 subapical megasetae near the tooth and 4 medial megasetae on the lobe, megasetae curved and hyalinous. Tegmen broader than long, straight apically and laterally, hyalinous but broadly sclerotized basolaterally, with tiny aedeagal teeth. Aedeagal apodeme broad, with distinct apical fork.

Female. Unknown.

Discussion. Pseudoaerumnosa annae sp. n. is very similar to P. formosa sp. n. in having the tegmen narrowed in the apical half and with broad sclerotized areas in the basolateral parts. Pseudolycoriella annae differs from P. formosa in having a more slender gonostylus and both a shorter medial lobe and shorter apical tooth. Both these species resemble P. inviolata but the latter has a broader and relatively shorter gonostylus. See also under P. tkoci .

Etymology. The species is named after Anna Vilkamaa, M.Sc., a specialist on Thailand vegetables.
