Sobarocephala sp.

( Figs 75–82 )

We believe this female specimen ( Fig. 75 ) belongs to a new species but has yet to be identified. No male was collected. The specimen fits the Sobarocephala flaviseta species group and the Sobarocephala plumata subgroup clade according to Lonsdale & Marshall (2012), in that it has a densely plumose arista, a reduced ocellar seta and a bulging face ( Figs 75, 77 ).

Female. Ocellar setae are minuten ( Fig. 76 ). Postpedicel with a brown infuscation dorsally ( Fig. 77 ). Postpronotal lobe with a dark yellow spot. Scutum brown to black laterally and a small faint prescutellar infuscation ( Figs 78– 79 ). Prescutellar acrostichal setae are slightly stouter than the surrounding setulae. Mesopleuron is yellow with the katepimeron and meron white ( Fig. 75 ). The legs are yellow with the distal fore tarsomeres 3–5 light brown. Vein M 1+2 ratio 4.1 ( Fig. 80 ). Abdomen ( Figs 78–79 ) black with tergite 1, base o tergite 2, entire tergite 5 and 7 are yellow. Terminalia ( Fig. 81 ). Spermatheca spherical ( Fig. 82 ).
