Treatment

Leucophenga cyclophylla View in CoL sp. nov.

( Figs. 2 View FIGURE 2 J, 4I, 4J, 8L, 18)

Diagnosis. This species resembles L. flaviclypeata sp. nov. in having the thorax mostly dark colored ( Figs. 4 View FIGURE 4 I, 4J, 5A, 5B), the wing fuscous along R1 only ( Fig. 2 View FIGURE 2 J, K), and in the color patterns of abdominal tergites in male ( Figs. 8 View FIGURE 8 L, 9A), but can be distinguished from the latter by the surstylus acute apically, lacking any seta laterally ( Fig. 18 View FIGURE 18 A), and the aedeagus slightly expanded distoventrally ( Fig. 18 View FIGURE 18 D); see below that species.

Description. Ocellar triangle dark brown, with ca. 1–2 seta(e) above ocellar setae. Frons brownish yellow. Pedicel brownish yellow; first flagellomere yellow. Clypeus brown. Palpus yellowish. Mesonotum mostly brownish ( Fig. 4 View FIGURE 4 I). Postpronotal lobe yellow ( Fig. 4 View FIGURE 4 J). Acrostichal setulae in ca. 8–10 irregular rows ( Fig. 4 View FIGURE 4 I). Scutellum entirely brown ( Fig. 4 View FIGURE 4 I). Pleura with a brown, longitudinal stripe above ( Fig. 4 View FIGURE 4 J). Katepisternum and meron brownish yellow, mostly brownish above ( Fig. 4 View FIGURE 4 J). Wing ( Fig. 2 View FIGURE 2 J): Costal vein between R2+3 and R4+5 distally with ca. 4 peg-like spinules on ventral surface. Abdominal tergites black ( Fig. 8 View FIGURE 8 L), with a pair of yellow patches submedially between 2nd to 3rd tergites. Male terminalia: Epandrium with ca. 1 seta near posterior margin per side ( Fig. 18 View FIGURE 18 A). Paramere with ca. 1 sensillum submedially ( Fig. 18 View FIGURE 18 C).

Type specimen. Holotype ♂ ( SCAU, No. 128887), CHINA: Menglun, Mengla , Yunnan, 780m, 10.iv.2010, ex tree trunk, YR Su .

Distribution. China (Yunnan).

Etymology. A combination of the Greek words “ cyclos ” (= round) + “ phyllon ” (= leaf), referring to the aedeagus rounded apically.
