Description

Male. Body black (Fig. 19). Head black, dark reddish brown between eyes, ocelli and eyes with yellowish border. Antennae, upper lip, mandible, labial palpi and maxillary palpomeres dark brown. Legs black, coxae, trochanter and the former half of femora yellowish brown. Abdominal sternites black with the middle of the former five segments reddish brown, cercus reddish brown (Fig. 20).
Vertex exposed, punctured; face densely punctured; ocelli circular and distinct. Pronotum convex (anterior margin damaged, it is probably a developmental error), anterior and lateral area depressed, densely granular and equally distributed; posterior half with a distinct tubercle on each side of the midline, the floor densely punctured (Fig. 69). Tegmina and wings mutilated, but probably fully developed (Fig. 19). Anterior ventral margin of front femur with 2 spines, and a minute distal spine, posterior margin with a spine. Centre region of abdominal tergites sparsely punctured, more and larger laterally, and with dense setae; lateral angle of T6 produced; T7 hirsute, with large disc pits densely; round holes only present in the anterolateral corners of T6 and T7; lateral margin of T7 with 3 subacute and distinct teeth, sometimes also with subobsolete papulas, caudal angle produced into a strong and oblique spine (Fig. 70). Abdominal sternites densely punctured; S7 densely covered with hairs, hind margin emarginated (Fig. 71), subgenital plate slightly exposed. Supra-anal plate convex, hirsute, with large disc pits densely; middle of hind margin with 8 unequal teeth, deflexed, which are triangular or apically truncate; caudal angles tapering, and same length as the largest tooth between them. Cerci conical, dorsal and ventral surfaces densely setose (Fig. 72). Anterior margin of subgenital plate depressed, anterolateral corners subacute, lateral margins straight and not concave (Fig. 73). Male genitalia. L1 well developed (Fig. 74); L2d not bifurcated with acute apex (Fig. 75); R2 hook-shaped (Fig. 76).
Female. Unknown.
Nymph. Unknown.

Measurements

Male, 3th–5th maxillary segments: 0.90/0.89/0.99mm; pronotum: length × width: 6.9 × 11.5mm; distance between disc tubercles: 2.8mm; body length: 32.2mm; fore leg: coxae: 2.99mm, trochanter: 2.54mm, femur: 4.04mm, tibia: 2.00mm, 1st–5th tarsus: 0.90/0.32/0.32/0.38/1.36mm; mid leg: coxae: 3.50mm, trochanter: 2.88mm, femur: 5.76mm, tibia: 4.34mm, 1st–5th tarsus: 1.09/0.33/0.34/0.42/1.30mm; hind leg: coxae: 3.32mm, trochanter: 3.36mm, femur: 6.77mm, tibia: 6.59mm, 1st–5th tarsus: 1.27/0.42/0.38/0.45/1.46mm; cerci: 0.93mm.

Material examined

Holotype, male, China: Yunnan Prov., Nujiang State, Gongshan County, Dulongjiang Township, Kongmu Village, 1391m, 27°44.79'N, 98°20.19'E, 25 May 2013, coll. Hao Xu and Jianyue Qiu (SWU).

Remarks

Owing to L2d not being bifurcated, this species should be placed under the Salganea raggei species group. It is superficially similar to Salganea aperturifera, but can be differentiated by the following characteristics: 1) posterior half of pronotum with 1 pair of tubercles, 2 pairs in Salganea aperturifera; 2) abdominal tergites 6 and 7 with holes in the anterolateral corners, T3–T7 with holes in Salganea aperturifera; 3) supra-anal plate convex, hind margin with 8 deflexed and unequal teeth, the teeth but in Salganea aperturifera the number of teeth is 8–10, which are subequal and undeflexed.

Etymology

The specific epithet “flexibilis” is derived from Latin, which means that the teeth on the hind margin of the supra-anal plate are deflexed.
