DNA sequences. The DNA sequence of COI barcode region taken from a paratype is deposited in GenBank. The Accession Number is provided in Table 1.

Description. Male. Head. Brown, antenna concolorous with face, maxillary palpus pale brown. Eye bridge?3 facets wide. Face with 12–18 long dark setae. Clypeus non-setose. Mouthparts strongly reduced. Maxillary palpus with one segment, with 2–5 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 1.9x 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 4–5 setae. Proepisternum with 4–5 setae. Scutellum with 4 long and many short setae. Wing. Fumose. Length 2.4–2.5 mm. Width/length 0.50. Anal lobe rather small. Hind margin with dorsal setae only. Veins distinct. R1/R 1.15–1.35. c/w 0.80–0.90. bM longer than r-m, stM longer than M-fork, stCu shorter than bM. R1 joining c before base of M-fork. R1 with dorsal setae, 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. 19 AView FIGURE 19. Brown, like the abdomen, broad; setae dark. Gonocoxa broad, slightly longer than gonostylus. Gonocoxae fused, ventromedial margin distinct, intergonocoxal area broad and short, microtrichose, setose medially. Setosity of gonocoxa long and dense. Apicomedial seta poorly differentiated. Gonostylus rather tumid, rather wide medially, impressed dorso- and ventromedially, with long roundish medial lobe, with rather short, slender, slightly curved apical tooth with a small megaseta attached to its ventral side, with 7–10 megasetae on the medial lobe, the megasetae short, slender and hyalinous, slightly curved. Tegmen broader than long, distinctly curved laterally, hyalinous but weakly sclerotized basolaterally, with tiny aedeagal teeth. Aedeagal apodeme distinct and long, with distinct apical fork.

Female. Unknown.

Discussion. See under Pseudoaerumnosa consuota  sp. n.

Etymology. The name is Latin, saginata  , fat, referring to the plump gonostylus.
