description: 7. Phlugiolopsis tribranchis sp. nov.
(Map.1, Figs. 8, 13: C–D)
Male. Body small. Fastigium verticis conical, stout, apex obtuse, furrowed in midline. Eyes subglobular, protruding forwards. Apical segment of maxillary palpi slightly longer than subapical one, apex slightly widened.
Pronotum short, anterior margin straight, metazona slightly raised, posterior margin obtusely rounded; lateral lobe longer than high, without humeral sinus.
Ventral margins of all femora unarmed. Procoxa with a short spine; protibia with 4 internal and 5 external spines on ventral margin separately, and 1 pair of ventral apical spurs; tibial tympana open on internal and external sides, oval. Mesotibia with 3 internal spines and 5 external spines on ventral margin, and a pair of ventral apical spurs. Genicular lobes of postfemur with apices obtuse; posttibia with 20–21 spines on each dorsal side, 1 pair of dorsal apical spurs and 2 pairs of ventral apical spurs.
Tegmina short, slightly surpassing posterior margin of pronotum, sometimes reaching the middle area of second abdominal tergite. Hind wings absent.
Lateral margin of ninth abdominal tergite slightly protruding backwards; posterior margin of tenth abdominal tergite with small notch in middle. Epiproct tongue-shaped. Basal half of cerci stout, interno-dorsal margin of basal area with 1 digitiform, lamellar process, apex obtusely rounded, curved interno-dorsad; ventral margin of middle area with 1 spatulate process, directed interno-ventrad; apical half conical, apex obtusely rounded, slightly incurved. Subgenital plate subtrapezoid, basal area slightly broad, narrowing, basal margin arched excavate, apical half curved dorsad, posterior margin directed ventrad, centre of posterior margin with obtuse-angled concavity, the lateral lobes triangular. Subapex of subgenital plate with long subconical styli on ventral margin, apices obtuse.
Female. Body slightly larger. Lateral margin of ninth abdominal tergite slightly protruding backwards; posterior margin of tenth abdominal tergite with 1 faintly concavity in middle. Epiproct triangular. Cerci stout, conical, apices acute. Ovipositor gently curved upwards, base stout, narrowing, dorsal valvulae sharply pointed and ventral ones with a small terminal hook. Subgenital plate broad and slightly somewhat large, basal margin slightly arched excavate, baso-lateral margin with 1 small spine-shaped process and 1 short transverse wrinkle on each side; lateral margin of one third basal area obviously concave; apical half rounded, the centre slightly straight or faintly concave.
Coloration. Body yellowish brown. Eyes black brown. Internal margin of antennal socket black brown, scape and pedicel light brown, flagellum yellowish brown, with some annulate brown stripes. Dorsum of head with 4 black brown stripes, outer stripes narrow and inner 2 stripes comparatively broad. Disc of pronotum brown, most outer area of basal half with black brown stripes. External margins of pro- and mesofemur with densely black brown spots; postfemur with light brown pinnate stripes. Apex of postfemur and posttibia, whole tarsi light brown. Lateral margin of abdominal tergites and male subgenital plate black brown. Lateral margin of abdominal tergites and male subgenital plate black brown.
Type material. Holotype: male, Meizihu, Puʹer, Yunnan, 27 August 2009, collected by Fu-Ming Shi. Paratypes: 1 male, Meizihu, Puʹer, Yunnan, 27 August 2009, collected by Fu-Ming Shi; 1 male, Meizihu, Puʹer, Yunnan, 27 August 2009, collected by Rui-Lian Li; 2 males and 1 female, Caiyanghe, Puʹer, Yunnan, 26 August 2009, collected by Ming Qiu; 4 females, Caiyanghe, Puʹer, Yunnan, 26 August 2009, collected by Ming Qiu and Rui-Lian Li. Other specimens (conserved in alcohol): 1 male, Meizihu, Puʹer, Yunnan, 26 August 2009, collected by Rui- Lian Li; 2 males and 1 female, Caiyanghe, Puʹer, Yunnan, 26 August 2009, collected by Ming Qiu and Rui-Lian Li.
Measurements (mm). Body: 37.1–8.2, Ƥ8.2–8.6; pronotum: 33.5–3.6, Ƥ3.5–3.6; tegmen: 31.6–1.9, Ƥ1.8–1.9; postfemur: 38.6–8.9, Ƥ9.1–9.5; ovipositor: 5.4–6.9.
Remarks. The new species differs from the known species of the genus Phlugiolopsis by: male cerci trifurcate with 2 processes; baso-lateral margin of female subgenital plate with 1 small spine-shaped process and 1 short transverse wrinkle on each side, one third basal area obviously concave.
Etymology. The name of the new species is derived from the morphology of the male’s cerci.
Distribution. China (Yunnan).
