Diagnosis.

Body yellow. Head brown. Antenna short, reaching pronotum if bent backward. Prescutum and presutural scutum with four yellow stripes, central stripes divided 2 / 3 posteriorly. Scutellum with cloud-shaped brown markings, large stripe in middle, two markings at upper-anterior corners. Wing with pale brown cloud-shaped pattern around most veins; stigma grayish-brown; crossvein m-cu nearly connected to M fork. Outer gonostylus goose-head-shaped at apex, mesal part slightly narrower than remaining; inner branch of paramere elongated, with apex acute. Aedeagus tongue-shaped.

Redescription.

Male. Body length 4.48–5.80 mm, wing length 4.43–6.12 mm, antenna length 0.71–0.83 mm ( N = 128).

Head (Fig. 1 a, b View Figure 1 ). Mostly brown. Vertex brown. Antenna pale brown, 16 - segmented, reaching base of pronotum if bent backward; scape cylindrical; pedicel narrower at base, with brown distal margin; flagellomeres oval, distal segments elongated, cylindrical, with erect sparse setae (Fig. 1 a, b View Figure 1 ).

Thorax (Fig. 1 a, c View Figure 1 ). Mostly brown. Pronotum brown, with dark-brown apex. Prescutum and presutural scutum yellow, with four indistinct brown stripes; median stripes partially divided posteriorly for approximately 2 / 3 of their length, with a narrow yellow seam between them. Postsutural scutum brown, scutal lobes each with blunt square pale spots at lower posterior corners. Scutellum brown with dark-brown lateral margin. Mediotergite brown, dark-brown marking at upper-anterior corners, with bright-yellow stripes on the upper side of these markings (Fig. 1 c View Figure 1 ). Legs with fore-coxae brown; mid-coxae and hind-coxae lighter; trochanters yellow, with brown margins; femora pale brown, slightly swollen distally; tibiae pale brown, with brown apices; tarsi brown, pale brown at base of first tarsi (Fig. 3 a View Figure 3 ).
