description: 3. Hemithyrsocera forcipata sp. nov.
Figs. 14–15, 44–55
Measurements (mm). Male, overall length including tegmina: 17.5–18.5; pronotum length × width: 3.1–3.4×4.1– 4.4; tegmina length: 15.0–15.3. Female, overall length including tegmina: 16.0–17.1; pronotum length × width: 3.1–3.5×4.0–4.3; tegmina length: 14.0–15.0.
Body dark brown (Fig. 14). Vertex yellowish brown. Face brown with wide yellowish brown band between eyes (Fig. 15). Ocellar spot pale yellow. Third maxillary palpomere yellowish brown with fourth and fifth maxillary palpomeres brown (Fig. 15). Pronotum dark brown with yellowish brown stripe, lateral and anterior borders yellowish brown (Figs. 14, 46). Tegmina brown with discoidal area yellowish brown; hind wings hyaline and pale yellowish brown. Fore legs pale brown with apices of all tibiae dark brown, femora pale brown with dark brown stripes. 6th–8th sternites yellowish brown with dark brown irregular maculae on the middle and lateral borders (Fig. 15).
Vertex with interocular space distinctly narrower than the distance between antennal sockets (Fig. 44). Third and fourth maxillary palpomeres approximately same length, and both slightly longer than the fifth (Fig. 45). Pronotum subelliptical, the middle of hind margin more or less produced (Fig. 46). Hind wings with radius area narrow, R1 with 4 branches, posterior branches of R extended behind the base of anterior rami of radius and bifurcated at apical; M simple, Cu with two branches; apical triangle distinct. Front femur Type A2 or A3 (Fig. 47). Seventh abdominal tergum specialized but without setae; laterally on each side, a rounded lobe, covered with minute setae, directed laterad and with base robust (Fig. 50). Supra-anal plate (Fig. 51) in ventral view symmetrical with hind margin rounded, right and left intercercal processes absent; right and left paraprocts dissimilar (Fig. 51), right one bifurcated with apices rounded or tapering, one larger spine arising from the middle; left one similarly bifurcated with apices truncate, one small spine arising from the middle. Subgenital plate in dorsal view strongly asymmetrical (Fig. 52), right side distinctly produced into one rounded lobe, whose apex is upturned and scattered with apical spines; two styli dissimilar with apical long hairs, arising from the middle of hind margin; hind margin with 3 processes, whose apices scattered with lots of teeth (Fig. 52).
Male genitalia. L3 (Fig. 53) long and slender, sclerotized portion small and without preapical incision; L2vm (Fig. 54) long, curved and slender with base pointed, one short and irregular accessory structure originated in the middle; R2 (Fig. 55) simple and irregular, R3 (Fig. 55) with 2 obvious sclerites, one of which nearly inversed Yshaped, the other small and irregular.
Material examined. Holotype: ♂, China, Yunnan Prov., Xishuangbanna, Jinghong, Dadugang, 1299m, 22°22.190' N, 100°56.977' E, 28 May 2014, leg. Li Xinran.
Paratypes: 1♂, Xishuangbanna, Jinghong, Dadugang, 29 May 2014, leg. Liu Hongguang; 1 ♀, same data as holotype.
Remarks. H. forcipata is closely related to H. simulans (Bey-Bienko, 1969) based on the body shape and color. It differs from H. simulans in the following: 1) right side of subgenital plate distinctly produced into one rounded lobe, two styli arising from the middle of hind margin; hind margin with 3 processes (in H. simulans, right posterolateral corners rounded, two styli arising from the middle and left corner of hind margin, hind margin uneven with 2 robust fingerlike processes); 2) apex of L2vm rounded (tapering in H. simulans); 3) both right and left paraprocts with small spines arising from the middle (large in H. simulans).
Etymology. The specific epithet “forcipatus” is derived from Latin, referring to the pronotum with pincersshaped, dark brown maculae.
Distribution. China (Yunnan Prov.).
