Figs. 12–13, 32–43
Parasymploce banvaneuensis Roth, 1985: 513.
Hemithyrsocera banvaneuensis, Roth, 1995: 962.
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).
Materials examined. 1♂, China, Yunnan Prov., Xishuangbanna, Jinghong, Dadugang, 22°22’190”N, 100°56’977″E, 29 May 2014, leg. Liu Hongguang; 2 ♂, Yunnan Prov., Xishuangbanna, Jinghong, Dadugang, 1296m, 22°22’190”N, 100°56’971”E, 28 May 2014, leg. Li Xinran.
Remarks. 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.
