(mainly following Roth 1977, 1979). Coloration dark reddish brown or black. Size ranging from 15 mm to over 50 mm. Body strongly sclerotized with a coarse surface, densely covered with punctations. Vertex foveolar or not, slightly exposed. Pronotum transversal ovate, anterior margin slightly convex, with a variable excision in the midline, or entire. If excised, the corners of the concavity protruding or not. Lateral margins of pronotum arched and the hind margin almost straight or slightly concave. The surface of the pronotum granular on variably depressed anterior half with a pair of oblique grooves and often with two disc tubercles on the posteriorly punctate half. Tegmina and wings unicoloured or not, fully developed (sometimes mutilated terminally or only leaving the basal portion of the tegmina and wings), or reduced, or tegmina reduced but wings absent, or both tegmina and wings absent. The tarsi of legs with five segments, pulvilli are present on segments 1–4. The hind metatarsus is shorter than the remaining segments combined. Claws symmetrical, without arolia. Abdominal terga with punctate surface, and the hind margins without spines, tubercles or teeth.

Anterolateral corners of terga rarely with holes and without setae, or just tergum six (T6) and tergum seven (T7) with holes. Lateral margins of T6 smooth, and laterocaudal angles not produced, or with a spine and directed caudally. Lateral margins of T7 straight and not crenulate, laterocaudal angles sometimes produced and usually directed caudally. Lateral margins of sternite seven (S7) with a feeble and short ridge or without ridge. In the male, the hind margin of the last sternite is truncate or concave, and the subgenital fig is slightly exposed. In the female, the hind margin of the last sternite is convex and rounded. Both sexes are without styli. Supra-anal fig punctate, with uneven or rounded hind margin, and cerci are short and broad basally. Paraprocts are asymmetrical, the left one in ventral view with a finger-like projection lacking in the right one. Anterior margin and lateral margins of subgenital fig concave and the hind margin is rounded. Four genital phallomeres as follow: first sclerite of the left phallomere (L1) figd; second ventromedial sclerite of left phallomere (L2vm) rod-like; second dorsal sclerite of the left phallomere (L2d) variable; second sclerite of the right phallomere (R2) well developed or reduced, if developed, it is often hook-like and curved to right side in dorsal view.

The genus Panesthia is recognized by both T6 and T7 having smooth lateral margins, their hind margins without tubercles; the hind angles of T7 spine-like, but T6 not. Some species in this genus may have individuals with mixed characters resembling the genus Salganea Stål, 1877, Ancaudellia Shaw, 1925 or Miopanesthia Saussure, 1895 (Roth 1982: 71). The first two genera can be distinguished from Panesthia by the anterolateral angles of terga usually with holes or grooves with associated setae, but species of Panesthia often lack holes, or if with holes in T6 and T7, the holes without setae. The last genus Miopanesthia, has a hind metatarsus that is usually close to or longer than the combined length of the remaining tarsal segments; however, the hind metatarsus is shorter than the remaining segments in Panesthia.

This subspecies is close to P. stellata stellata Saussure, 1895, but can be distinguished by the following characteristics: 1) nymph with broad yellowish band on mesonotum and metanotum, nymph of P. stellata stellata with two yellowish markings on mesonotum and without markings on metanotum; 2) anterior margin of pronotum with an excision in both sexes and the corners of the excision upturned in male; anterior margin of pronotum entire or slightly concave in both sexes of P. stellata stellata. Feng and Woo (1990) identified the material collected by Fusheng Huang as P. stellata Saussure, 1895. But after our critical examination, it should be treated as a new subspecies.

The subspecific epithet is derived from the Latin word “concavus” which refers to the hind margin of the yellowish mark on nymphs being concave.

Male. Body dark brown or black (Fig. 13). Face black, eyes brown or black, ocelli pale yellowish and upper lip yellowish brown. Antennae black, terminal segments light brown. Abdominal sternites reddish brown with the middle of anterior three sternites brown (Fig. 14). Legs reddish brown with coxae and trochanter brown, tarsal pulvilli pale (Fig. 14).

Vertex slightly punctate, exposed (Fig. 49). Face punctulate, ocelli small, round. Pronotum transverse ovate and flat; anterior margin convex or straight, center weakly concave, lateral corners of the indentation slightly incrassate and upturned; lateral margins convex and widest at or before the midline; hind margin straight; anterior 1/3 of pronotum shallowly depressed and delineated by two grooves, the surface sparsely granular; posterior half flattened and punctate densely, with two small disc tubercles (Fig. 49). Tegmina and wings well developed (Figs 50–51), extending to or surpassing the tip of abdomen (Fig. 13), few reaching to the hind margin of 6^th tergite, sometimes mutilated terminally. Anterior ventral margin of front femur with 0–1 spine and with a small distal spine, hind margin with a large distal spine. Abdominal tergites punctate, with punctations denser caudally, anterolateral corners without holes. Caudal angles of 6^th tergite weakly extended; lateral margins of 7^th tergite smooth, caudal angles acute and directed caudally (Fig. 52). Abdominal sternites punctate, hind margin of the 7^th sternite weakly concave and subgenital fig exposed (Fig. 53).

This species is similar to P. angustipennis spadica, but can be distinguished by the following characteristics: 1) anterior margin of pronotum weakly concave in male, and without mesal elevation, male of latter with anterior margin broadly excised and with mesal elevation; 2) body length < 30 mm in most, or few surpassing 30 mm, body length of P. angustipennis spadica > 30 mm.

The specific epithet is named after the locality of the holotype, Guizhou Province.

This species is distinguished from other species by its small body length, ranging from 22.5 mm to 28 mm; and also by pronotum virtually flattened, anterior margin slightly thickened, entire or weakly indented in male, entire and not thickened in female (Fig. 68); as well as the caudal angles of T7 acute and posteriorly directed (Fig. 71); hind margin of supra-anal fig smooth or slightly crenulate, with the lateral teeth acute in apexes (Fig. 73); anterior ventral margin of front femur with 0–3 spines and with small distal spine, and posterior ventral margin with a large distal spine. The caudal angles of T6 sometimes with an acute spine separately may confuse this species with species in the genus Miopanesthia, but can be distinguished by the shorter hind metatarsus, as stated in the genus remarks. Roth (1979) determined that the tegmina and wings were polymorphic in this species since the specimens he examined had both the macropterous and brachypterous forms. The tegmina and wings are fully developed (Figs 19, 69–70) or mutilated on all material of this species we examined.

This species is similar to P. angustipennis spadica, but can be distinguished by body length (19–29 mm), which is commonly smaller than the latter (34–42 mm). In male of P. sinuata, the anterior margin of pronotum is broadly concave and the corners of the indentation upturned (Fig. 74), while the latter is merely concave and without corners in small individuals about 34 mm. The anteroventral margin of front femur often bears 0–1 spine in P. sinuata, but more than two spines in P. angustipennis spadica. Roth (1979) described this species as similar to P. antennata, but the male of the latter had no mesal elevation of the anterior margin of pronotum.

This subspecies resembles P. angustipennis spadica, and it is difficult to distinguish adults. Roth (1979) stated P. angustipennis spadica had a deflexed hind margin of the supra-anal fig and appeared to be entire dorsally, not deflexed and with teeth visible dorsally in P. angustipennis cognata. Despite this character being variable, some of the populations were sufficiently different, and distinct on average. It is significant that L2d of median phallomere in P. angustipennis cognata is short with variable apex, but elongate and tapering to a round apex in P. angustipennis spadica. Nymphs of P. angustipennis cognata have a broadly yellowish marking on mesonotum and metanotum (Fig. 25) while P. angustipennis spadica is with or without two markings on mesonotum, and without any markings on metanotum.
