Description.

Body length: male 6.7-6.9mm (N = 7), female 6.7-7.8mm (N = 16).

Coloration. General color blackish brown (Figs 3-4, 21-24). Eyes mid brown, ocelli light yellow. Vertex blackish brown. Face mid to blackish brown, carinae lighter; rostrum mid to blackish brown. Pronotum mid to blackish brown with carinae lighter; mesonotum mid to blackish brown, area between lateral carinae lighter. Forewing semi-translucent, light brown, stigma mid brown. Hind tibiae and abdominal sternites blackish brown.

Head and thorax. Vertex (Fig. 21) narrow, 3.5 times longer than wide; frons (Fig. 22) 1.7 times as long as wide. Forewing (Fig. 25) 3.0 times longer than wide, with 12 apical and 6 subapical cells; fork Sc+RP distal to fork CuA1+CuA2; RP 4 branches, MA 3 branches, MP 2 branches. Hind tibia with 4 lateral spines; chaetotaxy of hind tarsi: 7/5.

Male genitalia. Pygofer (Figs 26-27), dorsal margin concave and U-shaped ventrally, widened towards apex; in lateral view, lateral lobes triangularly extended caudally. Medioventral process narrowly triangular ventrally. Anal segment (Figs 26, 28-29) tubular, asymmetrical, widened towards apex in left side view; in right side view, left ventral margin convex and right ventral margin excavated near apex; 1.8 times longer than wide in dorsal view; anal style fingerlike, beyond anal segment. Genital styles illustrated in Fig. 30. Aedeagus (Figs 31-34) in total with five processes. Spinose process on right side near apex of periandrium long, directed right-dorsocephalically, more than 1/2 of periandrium in length; left side near apex of periandrium with a short reversed spinose process, curving slightly, directed dorsocaudally. Flagellum tapering, apex curved in a semi-circle; a long spinose process arising from dorsal margin, reaching to basal margin of periandrium, curving right side, directed ventrocephalically; left side with a short triangular process, directed ventrocephalically.

Female genitalia. Genitalia as shown in Fig. 57 ventrally. Anal tube (Fig. 58) 1.9 times longer than wide in dorsal view. Posterior vagina (Figs 59-60) elongate, with a long longitudinal sclerite dorsally, large. In ventral view, left side with a long longitudinal sclerite, semi-sclerotized, right side with a large median constricted sclerite, which with a process, the process directed left-ventrally and longer than shown in the figure.

Distribution.

China (Yunnan).

Etymology.

The specific name is derived from the Latin productus , referring to the dorsal margin of flagellum with a long process.

Remarks.

Male genitalia of O. productus sp. n. is similar to O. articara , but differs in: (1) left side near apex of periandrium with a short process (in O. articara , left side without process); (2) a very long spinose process arising from dorsal margin of flagellum (dorsal margin of flagellum without process in O. articara ); (3) left side near apex of flagellum with a very short process (in O. articara , left side near middle of flagellum with a much longer process); 4) forewing with RP 4 branches (in O. articara , 3 branches).

Female genitalia of O. productus sp. n. is similar to O. yoshikawai , but differs in: (1) right side of posterior vagina with one sclerite, which constricted medially in ventral view in O. productus (with two sclerites, terminal irregular sclerite forming three projecting oblong structures in ventral view in O. yoshikawai ); (2) in ventral view, distal part of the sclerite on left side of posterior vagina not extended and curved to right in O. productus (extended and curved to right in O. yoshikawai ).
