Neocyrtopsis (Paraneocyrtopsis) platycata ( Shi & Zheng, 1994) Shi com. nov.

Fig. 1

Redescription. Male. Body stout. Head hypognathous, fastigium verticis protruding anteriorly, conical with a thin longitudinal sulcus, apex rounded. Eyes subglobular, prominent. Apical segment of maxillary palpi longer than subapical one, apex slightly enlarged.

Pronotum short, not reaching middle area of first abdominal tergite; anterior margin straight, posterior margin obtusely rounded, transversal sulci indistinct; lateral lobe longer than deep, posterior margin not broadened, inclining, humeral sinus absent.

All femora without spines on ventral margin. Forecoxa with a spine, foretibiae with 5 pairs of spines (including a pair of apical spines) on ventral margin, tibial tympana open on inner and outer sides, long-oval.

Mesotibiae with 3–4 spines on inner side and 4–6 spines on outer side of ventral margin. Postfemur with genicular lobes rounded, with 24–16 spines on inner and outer sides of dorsal margin, one pair of dorsal apical spurs and two pairs of ventral apical spurs. Thoracic auditory spiracle comparatively large.

Tegmina short, mostly concealed under pronotum, (in some specimens slightly longer, reaching posterior margin of first abdominal tergite); hindwings absent.

Ninth abdominal tergite moderately longer, lateral margins broadened posteriorly. Tenth abdominal tergite elongated, basal half with a longitudinal sulcus, posterior area merged with epiproct; the lateral lobes protruding posteriorly, apices bifoliate; posterior margin of the centre with a rectangular notch. Cerci short, apices hookshaped, curved inwards. Genitalia with broad base, middle area thin and long, apex enlarged, bilobed, and surpassing apex of subgenital plate, covering it. Basal area of subgenital plate broad, concave; apical half narrow, protruding posteriorly, ventral margin convex ventrally, apical area with some stout spines; apex truncate. Styli longer, apices subacute on middle area of both lateral margins.

Body yellowish brown. Dorsum of head brown, inner margin of antennal sockets and eyes brown. Disc of pronotum with a broad longitudinal brown stripe, lateral lobes yellowish white, ventral margin brown. Foretibiae of ventral margin with spines brown and tarsi brown. Mesotibiae light, tibial spines and claws brown. Outer margin of postfemora with two rows of light brown spots, apices of genicular lobes brown; posttibiae with basal area brown, the other area light brown, tibial spines, spurs and claws brown. Abdominal tergite brown, some area light. Basal area of subgenital plate brown. Genitalia light brown.

Female. Appearance and coloration are alike to male. Tegmina oval, separated laterally. Thoracic auditory spiracle comparatively large, distinct. Ninth abdominal tergite slightly longer, centre of posterior margin straight, lateral area broadened posteriorly, apex obtusely rounded. Tenth abdominal tergite shorter, posterior margin protruding, the centre with a triangular concavity. Epiproct distinct, small, triangular. Cercus conical, apex thin and acute, slightly curved dorsally. Ovipositor moderately curved upwards, dorsal margin smooth, apical half of ventral margin with small teeth. Subgenital plate ovoid, basal area slightly narrower, straight, middle area broadened, posterior margin rounded. Female is reported for the first time.

Specimens examined. 10312♀, Emeishan, Sichuan, China, 31 July – 4 August 2011, collected by Fu-Ming Shi and Le-Hong Zhao.

Measurements (mm). Body (from apex of fastigium verticis to posterior margin of tenth abdominal tergite): 311.5–12.0, ♀12.0–12.5; pronotum: 33.8–3.9, ♀4.0–4.1; tegmina: 31.2–1.5, ♀1.4–1.5; postfemora: 310.0–12.0, ♀11.8–12.5; ovipositor: 5.2–5.5.

Distribution. China: Sichuan (Emeishan).

Discussion. The species distinctly differs from the other species of the genus Neocyrtopsis Liu & Zhang, 2007 in: male genitalia with broad base, middle area thin and long, apex enlarged, bilobed, and surpassing apex of subgenital plate; basal area of subgenital plate broad, apical half narrow, protruding posteriorly, ventral margin convex ventrally, apical area with some stout spines; apex truncate; with styli on middle area of lateral margins.
