Description
. Male.
Head
. Brown, antenna concolorous with face, maxillary palpus pale brown. Eye bridge 3 facets wide. Face with 6 dark long setae. Clypeus non-setose. Mouthparts strongly reduced. Maxillary palpus with one segment, with 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 1.4x 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 setae. Proepisternum with 3 setae. Scutellum with 2 long and many short setae.
Wing
. Fumose. Length
2.6 mm
. Width/length 0.50. Anal lobe moderate. Hind margin with dorsal setae only. Veins distinct. R1/R 1.50. c/w 0.85. bM, r-m and stCu subequal in length, stM longer than M-fork. 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 longer than the tibial width.
Abdomen
. Pale brown; setae dark, long and robust.
Hypopygium,
Fig. 12 B
. Brown, like the abdomen, broad; setae dark. Gonocoxa broad, longer than gonostylus. Gonocoxae fused, ventromedial margin distinct, intergonocoxal area broad and moderate, sparsely microtrichose, broadly non-setose medially. Setosity of gonocoxa dense, shorter at medial margin. Apicomedial seta well differentiated. Gonostylus elongated, evenly broad, slightly narrowed apically, impressed, with small apical tooth with a small megaseta attached to its ventral side, with some elongated subapical setae and 6 subapical-medial megasetae, the megasetae slender, short and hyalinous, curved. Tegmen semicircular, hyalinous but weakly sclerotized basolaterally, with tiny aedeagal teeth. Aedeagal apodeme indistinct and short with robust apical fork.
Female
. Unknown.
Discussion.
Pseudoaerumnosa filispicata
sp. n.
resembles
P. pilicaudata
sp. n.
in having a broad gonocoxa, an evenly wide gonostylus with a tumid apex and a small apical tooth of the gonostylus.
Pseudoaerumnosa filispicata
differs in having an apically and laterally roundish tegmen and a more slender gonostylus with some distinct pointed subapical setae.
Etymology.
The name is derived from the Latin words
filum
, thread, and
spica
, point, referring to the pointed setae on the gonostylus.
