Fig. 14 BView FIGURE 14

Material studied. Paratypes. TAIWAN, NE Puli, Meifeng , 2100 m, 26.VI–28.VII.1997, Lin & Yang, 4 males (in ZSM)  .

Redescription. Male. Head. Brown, antenna concolorous with face, maxillary palpus pale brown. Eye bridge 2–3 facets wide. Face with 5–10 long dark setae. Clypeus non-setose. Mouthparts strongly reduced. Maxillary palpus with one segment, with 2–4 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 2.2x 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 3–11 setae. Proepisternum with 2–4 setae or non-setose. Scutellum with 4 moderately long and many short setae. Wing. Fumose. Length 2.6–3.5 mm. Width/length 0.50. Anal lobe rather large. Hind margin with dorsal setae only. Veins distinct. R1/R 1.65–2.25. c/w 0.75–0.90. bM as long as r-m, or r-m longer. stM longer than M-fork. stCu subequal with bM. R1 with dorsal and ventral setae, bM non-setose, r-m non-setose or with 1 seta. 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 14 BView FIGURE 14. Brown, like the abdomen, broad; setae dark. Gonocoxa slightly longer than gonostylus. Gonocoxae fused, intergonocoxal area broad and short, without microtrichia, narrowly non-setose medially, ventromedial margin roundish and distinct. Gonocoxa largely microtrichose, setosity long and dense, slightly shorter at medial margin. Apicomedial seta poorly differentiated. Gonostylus broad, impressed dorso- and ventromedially, with a short medial lobe, with a short, basally slightly constricted apical tooth with a small megaseta attached to its ventral side, with 2 megasetae subapically and 3–5 on the lobe, megasetae rather short, hyalinous and slightly curved. Tegmen broader than long, straight apically, roundishly curved laterally, hyalinous but weakly sclerotized basolaterally, with tiny aedeagal teeth. Aedeagal apodeme rather long, with distinct apical fork.

Female. Unknown.

Discussion. Only the paratypes, from the same locality as the holotype, were studied. The paratypes are in a rather poor condition (the hypopygium in Fig. 14 BView FIGURE 14 is flattened in preparation). Pseudoaerumnosa inviolata Rudzinski  most closely resembles P. clivicola  sp. n.
