Measurements (mm). Male , overall length including tegmina: 17.9–18.5; pronotum length × width: 3.0–3.3×4.0– 4.3; tegmina length: 15.0–15.3. Female , overall length including tegmina: 16.1–17.0; pronotum length × width: 3.0–3.4×4.0–4.3; tegmina length: 14.0–14.9. Body medium, brown or dark brown ( Fig. 12 ). Vertex yellowish brown. Ocellar spot pale yellow. Face dark brown with one irregular yellowish brown macula between eyes and antennal sockets ( Fig. 13 ). Maxillary palpomere brown ( Fig. 13 ). Pronotum dark brown with yellowish brown maculae and stripe ( Fig. 12 , 34 ). Tegmina brown with discoidal area yellow; hind wings hyaline and pale yellowish brown. Fore legs pale brown, middle legs yellowish brown and hind legs yellowish brown. Sterna yellowish brown with pale brown maculae on lateral borders ( Fig. 13 ). Vertex with interocular space distinctly narrower than the distance between antennal sockets ( Fig. 32 ). Third and fourth maxillary palpomeres approximately same length, and both longer than the fifth ( Fig. 33 ). Pronotum subelliptical, the middle of hind margin somewhat produced ( Fig. 34 ). Hind wings with radius area narrow, R1 with 3 branches, posterior branches of R extended behind the anterior rami of radius and bifurcated at apical; M simple, Cu with two branches; apical triangle distinct. Front femur Type A2 or A3 ( Fig. 26 ). Seventh abdominal tergum specialized but without setae; laterally on each side, a rounded lobe, covered with minute setae, directed posterior-lateral and with base robust ( Fig. 38 ). Supra-anal plate ( Fig. 39 ) symmetrical in ventral view and nearly triangular, hind margin strongly convex in the middle, posterior region scattered with a few small spines; intercercal process absent; right and left paraprocts dissimilar and irregular, each with an acute spine arising from the base. Subgenital plate ( Fig. 40 ) asymmetrical in dorsal view; right and left lateral margin concavely excavated and upturned, right style broad with dense brush of long setae, left style smaller with group of apical setae; hind margin produced and concavely excavated, and one large style-shaped process with group of apical setae arising from the posterior region. Male genitalia. L3 ( Fig. 41 ) long and slender, without preapical incision; L2vm ( Fig. 42 ) long and slender, distinctly curved and basally tapering, twinned with a long sclerite by membrane; R2 with a large and irregular sclerite and R3 with 2 sclerites, one of which large and inversed Y-shaped, the other nearly C-shaped ( Fig. 43 ). FIGURES 32–43. Hemithyrsocera banvaneuensis (Roth, 1985) , male: 32 head; 33 maxillary palp segments 3–5; 34 pronotum; 35 front femur; 36 tegmen; 37 hind wing; 38 seventh abdominal tergum; 39 supra-anal plate and paraprocts, ventral view; 40 subgenital plate, dorsal view; 41 hook-like phallomere (L3); 42 median phallomere (L2vm); 43 right phallomere (R2 and R3).

H. banvaneuensis resembles H. simulans , but differs in the following characteristics: 1) hind margin of supra-anal plate strongly convex in the middle, posterior region nearly triangular with a few small spines, while in H. simulans , hind margin of supra-anal plate broadly convex in the middle, posterior region nearly hemispherical without spines; 2) subgenital plate with one large style-shaped process with apical setae, while in H. simulans , subgenital plate with 2 robust fingerlike processes, whose apices scattered with lots of small teeth; 3) L2vm distinctly curved and apically tapering, twinned with a long sclerite by membranous cuticle, while in H. simulans , L2vm slightly curved and apically round, associated with an irregular sclerite by membranous cuticle. Distribution. China ( Yunnan Prov.), Laos .
