(Figs. 2 O, 5I, 5J, 9G, 9H, 23)
Diagnosis. This species differs from the other species of the subpollinosa group by having the mesonotum mostly yellow, brownish posterolaterally (Fig. 5 I), the cercus larger than epandrium in lateral view (Fig. 23 A), and the aedeagus laterally with a process bearing a sensillum at tip (Fig. 23 D).
Description. Ocellar triangle dark brown, with ca. 1–2 seta(e) above ocellar setae. Frons yellow to brownish yellow. Pedicel yellow to brownish yellow; first flagellomere yellowish. Clypeus brownish yellow medially, brown laterally. Palpus brownish yellow. Postpronotal lobe yellow (Fig. 5 J). Acrostichal setulae in ca. 10–12 irregular rows (Fig. 5 I). Scutellum yellow, dark brown laterally, yellowish at tip (Fig. 5 I). Pleura with a brown, longitudinal stripe above (Fig. 5 J). Katepisternum yellow, brown above (Fig. 5 J). Meron yellow, brownish above (Fig. 5 J). Wing (Fig. 2 O): Costal vein between R2+3 and R4+5 distally with ca. 4–6 peg-like spinules on ventral surface. Abdominal tergites dark brown to black (Fig. 9 G, H), 2nd tergite mostly yellow, 3rd and 4th tergites with a pair of yellow patches subanteromedially. Male terminalia: Epandrium with ca. 2 setae near posterior margin per side (Fig. 23 A). Surstylus acute apically (Fig. 23 A). Paramere with ca. 4 sensilla distally (Fig. 23 C).
