Type material.

Holotype: ♂, China: Yunnan Province, Jingdong County, Taizhong Town (24°30'N, 100°56'E), 18 August 2009, Bin Zhang; paratypes: 1♂, 2♀♀, same data as holotype; 1♀, Yunnan Province, Jingdong County, Dajie Town, 22 August 2009, Bin Zhang; 3♂♂, 2♀♀, Yunnan Province, Lanping County, Lajin Town, 4 August 2012, Yong-Gang Xiao.

Description.

Body length: male 6.7-7.7mm (N = 5), female 7.0-9.0mm (N = 5).

Coloration. General color mid brown (Figs 1-2, 7-10). Eyes mid brown, ocelli yellowish brown. Vertex blackish brown. Face yellowish to blackish brown, carinae lighter; rostrum blackish brown. Pronotum mid to blackish brown with carinae yellowish or light brown; mesonotum mid to blackish brown, sometimes area between lateral carinae lighter. Forewing semi-translucent, light brown, stigma yellowish or mid brown. Hind tibiae and abdominal sternites mid brown.

Head and thorax. Vertex (Fig. 7) narrow, 4.3 times longer than wide; Frons (Fig. 8) 1.3 times as long as wide. Forewing (Fig. 11) 3.0 times longer than wide, with 11 apical and 6 subapical cells; fork Sc+RP distal to fork CuA1+CuA2; RP 3 branches, MA 3 branches, MP 2 branches. Hind tibia with 3-4 lateral spines; chaetotaxy of hind tarsi: 7/5.

Male genitalia. Pygofer (Figs 12-13) dorsal margin concave and U-shaped ventrally, widened towards apex; in lateral view, lateral lobes triangularly extended caudally. Medioventral process triangular ventrally. Anal segment (Figs 12, 14-15) tubular, asymmetrical, widened towards apex in left side view; in right side view, left ventral margin convex and right ventral margin excavated near apex; 1.9 times longer than wide in dorsal view; anal style fingerlike, beyond anal segment. Genital styles illustrated in Fig. 16. Aedeagus (Figs 17-20) in total with four processes. Spinose process on right side near apex of periandrium long, directed right side, more than 1/2 length of periandrium. Flagellum terminating into a bifurcate process, asymmetrical; left side near apex of flagellum with a large laminal process, apex transversal and directed left side.

Female genitalia. Genitalia as shown in Fig. 49 ventrally. Anal tube (Fig. 50) 1.8 times longer than wide in dorsal view. Posterior vagina (Figs 51-52) elongate, with a long longitudinal sclerite dorsally, large. In ventral view, left side with a long longitudinal sclerite; right side with a rhombic sclerite basally, which with a process, the process directed left-ventrally and longer than shown in the figure, terminal area with a triangular sclerite.

Distribution.

China (Yunnan).

Etymology.

The specific name is derived from the Latin word " laminatus  ", referring to the left side of flagellum with a large laminal process.

Remarks.

Male genitalia of O. laminatus  sp. n. is similar to O. bifidus  , but differs in: (1) left side near apex of flagellum with a laminal process, apex transversal and directed left side (in O. bifidus  , with a spinose process, apex pointed, curved right-dorsally); (2) process on right side of periandrium directed right side (directed left side slightly in O. bifidus  ); (3) left ramus of bifurcate process longer than right one (in O. bifidus  , left ramus of bifurcate process shorter than right one); (4) vertex rather narrow, about 4.3 times longer than wide (in O. bifidus  , about 1.6 times).

Female genitalia of O. laminatus  sp. n. is similar to O. mori  , but differs in: (1) terminal area on right side of posterior vagina with a triangular sclerite in O. laminatus  (the sclerite long and narrow, curved, towards the right in O. mori  ); (2) left side of posterior vagina with a straight sclerite ventrally in O. laminatus  (the sclerite in the same position much longer and curved, towards the right in O. mori  ).
