Type material. Holotype: male, China, Yunnan, Mengla, Mengxing , 6 August 2021, coll. by Ping Yang . Paratypes: 2 males and 2 females, other information as holotype.
Diagnosis. The new subspecies differs from Ultragryllacris pulchra pulchra Gorochov & Dawwrueng, 2015 in: head and pronotum reddish purple; pronotum with 1 pair of separate black spots at anterior and posterior margins separately, but spots of posterior margin usually lighter; posterior margin of male subgenital plate with one shallowly concavity in the middle; female subgenital plate longer than wide with narrower posterior margin. It may represent a distinct species but for now we considerate a geographic race of the nominate species.
Description. Male. Body large. Fastigium verticis almost twice as broad as scape ( Fig. 1A View FIGURE 1 ), apex slightly concave. Frons with very fine transverse riffles and sparse punctures. Eyes long oval, projecting forward and outward; median ocellus much larger than lateral ocelli, circular; lateral ocelli small, pale. Apical segments of maxillary palpi as long as subapical ones, apices slightly inflated.
Pronotum with a pair of hook-shaped notches in the middle of lateral lobes, anterior margin slightly projected, posterior margin nearly straight ( Fig. 1B View FIGURE 1 ); lateral lobes longer than high ( Fig. 1C View FIGURE 1 ).
Tegmina surpassing the apices of hind femora, reaching the middle area of hind tibiae ( Fig. 4A–B View FIGURE 4 ). Radius with two branches, both forked near tip; media anterior free from base; left tegmen ( Fig. 3A View FIGURE 3 ): MA divides into MA and MP, then MP divides again into 2 branches, the first branch fused with MA in subapical area, cubitus anterior free from base, single branched; right tegmen ( Fig. 3B View FIGURE 3 ): MA undivided but sends a short connecting vein to anterior branch of cubitus anterior after that forked into two veins, then the first vein (MP) fused with MA. Both tegmina: Cubitus posterior undivided, free throughout; with 4 anal veins, last two with common stem. Hind wings slightly surpassing the tegmina.
Fore coxae with a sharp spine. Fore and middle femora unarmed on ventral surface, tibiae with four pairs of spurs on ventral surface plus one pair of apical spurs, dorsal surface of middle tibiae without apical spine. Hind femora with 14–15 internal spines and 8–9 external spines on ventral surface; tibiae with 7 pairs of spines on dorsal surface, ventral surfaces with one pre-apical spur each; with 3 apical spurs on both sides.
Second and third abdominal tergites without stridulatory pegs ( Fig. 1D View FIGURE 1 ). Ninth abdominal tergite prolonged, curved downwards, forming 1 large trapeziform process, basal area wider, narrowing to apex, apical third area slightly widened, posterior margin convexly subtruncate, ventral surface with a vertical ridge coalesced by 2 lobes which basal area have a sclerite ( Fig. 1F–G View FIGURE 1 ). Tenth abdominal tergite narrow and usually hidden. Subgenital plate broader than long, posterior margin with a shallow concavity in the middle, apex obtusely rounded ( Fig. 1H–I View FIGURE 1 ). Styli short, robust located on both sides of the subapical area of subgenital plate ( Fig. 1H–I View FIGURE 1 ).
Colouration. Body yellowish brown. Head and pronotum reddish purple. Clypeus, labium, and mandibles black, dorsum of head with black spots along the midline ( Fig. 1B View FIGURE 1 ). Eyes blackish brown, behind margin with a large black spot on each side; ocelli yellowish. Internal margins and ventral margins of antennal socket, internal surface of scape, and pedicel black ( Fig. 1A–B View FIGURE 1 ). Pronotum with brown margins, anterior and posterior margins with a pair of black spots separately ( Fig. 1B View FIGURE 1 ). Basal area of femora and apical area of tibiae blackish, spines of all legs yellowish brown ( Fig. 3A–B View FIGURE 3 ). Sclerite of ventral surface of ninth abdominal tergite black ( Fig. 1H–I View FIGURE 1 ).
Female. Appearance of female is similar to male, but lighter. Posterior margin of pronotum with yellowish brown spots ( Fig. 2B–D View FIGURE 2 ). Tegmen ( Fig. 3E–F View FIGURE 3 ): Radius with two branches, both forked near tip; media sends a short connecting vein to anterior branch of cubitus anterior after that forks into two veins, the first vein (MP) fused with MA. Cubitus posterior undivided, free throughout; with 4 anal veins, the last two with common stem. Seventh abdominal sternite normal, posterior margin arched concave, followed by a sclerotised transverse bulge ( Fig. 2J View FIGURE 2 ). Subgenital plate longer than wide, narrowing to apex, posterior margin with a shallow concavity in the middle ( Fig. 2J View FIGURE 2 ). Ovipositor longer than hind femora ( Fig. 4–D View FIGURE 4 ), straight, apices obtusely rounded ( Fig. 2K View FIGURE 2 ).
Distribution. Yunnan (Mengla).
Measurements (mm). Male: BL 32.0–39.2, PL 7.0–8.8, HFL 17.0–21.4, TL 38.9–40.5. Female: BL 30.0–37.1, PL 8.0–9.1, HFL 19.5–21.4, TL 34.5–37.2, OvL 25.5–30.2.
Etymology. This new subspecies name originates from the Latin rub (reddish purple) and capit (head), alluding to the coloration of head.
