description: 2. Xiphidiopsis (Xiphidiopsis) spoona sp. nov.
(Fig. 2)
Description. Male. Fastigium verticis conical, apex slightly rounded, with a distinct longitudinal sulcus. Eyes oval and protruding forward. Apical segment of maxillary palpi about equal to subapical one in length, apex faintly inflated.
Anterior margin of pronotum nearly straight, posterior margin obtusely rounded (Fig. 2A); lateral lobes longer than high and humeral sinus shallow (Fig. 2B). Thoracic foramen exposed and kidney-like (Fig. 2B). Tegmina extending beyond apices of metafemora distinctly; hind wings longer than tegmina by approximately 1 mm. Procoxa with a spine; protibia with 4 long spines and 2 short apical spines of outer side and 4 long spines and 1 short apical spines on inner side on ventral surface; tibial tympana open on both sides and ovoid. Mesotibia with 4 long spines and 2 short apical spines of outer side and 4 long spines and 1 short apical spine of inner side on ventral surface. Metatibia with 32–36 outer and inner spines on dorsal surface respectively, as well as 1 pair of dorsal apical spurs and 2 pairs of ventral apical spurs.
Posterior margin of tenth abdominal tergite with an asymmetric process, of which slightly stout, middle area thin, near apical area slightly swollen with a lamellar process on ventral surface; apical area compressed and pointing to left in circa 90° with apex bluntly rounded (Fig. 2E, G). Cerci asymmetric; left cercus shorter than right one, with base broad and slightly concave on inner side; dorsal surface of near middle area with a long, lamellate and spine-like process, curved interiorly and posteriorly and its apex subacute; 1/3 apical area curved interiorly, twisted and apex slightly expanded (Fig. 2 I–J). Right cercus with base broad, dorsal surface of near 1/3 basal area with lamellate and spine-like process, of which curved interiorly and apex subacute; near the middle compressed; and 1/3 apical area curved anteriorly, dorsal surface bulging and groove-shaped in ventro-lateral view (Fig. 2 G–H). Subgenital plate with 1/3 base broader and with a triangular concavity; middle area narrow, and 1/3 apical area divided into one pair of lateral lobules, its apical area wider, ovoid, spoon-like and with a small lamellate process on dorsal surface (Fig. 2E); styli absent (Fig. 2F); genitalia completely membranous.
Colouration. Body greenish. Eyes brown. Fastigium verticis with basal area brown. Area after eye with a short dark brown stripe separately. Pronotal disc with a pair of longitudinal blackish brown stripes nearly parallel (Fig. 2A). Tegminal stridulatory field light brown. Metafemoral genicular lobules with a black spot on inner and outer sides respectively, and spinules of metatibiae on dorsal surface brown.
Female. Appearance is similar to male. Cercus conical, and apex acute. Subgenital plate near trapezoid (slightly deformed), basal area broad, apical area slightly narrower and posterior margin with a shallow emargination and lateral lobules triangular (Fig. 2I). Ovipositor moderately curved dorsad, with basal area stout, apices of dorsal valvulae acute and apices of ventral ones hook-shaped.
Material examined. Holotype: ♂, Daweishan, Pingbian, Yunnan, 12 August, 2019, coll. Peng Cui. Paratype: 1♀, other data same as holotype.
Measurements (mm). Body: ♂ 10.0, ♀ 10.2; pronotum: ♂ 4.0, ♀ 4.1; tegmina: ♂ 20.2, ♀ 22.6; metafemora: ♂ 11.6, ♀ 11.8; ovipositor: 7.5.
Distribution. China (Yunnan).
Discussion. The new species most resembles Xiphidiopsis (Xiphidiopsis) anisolobula Han, Chang & Shi, 2015, Xiphidiopsis (Xiphidiopsis) tembelingi Gorochov, 2015, and Xiphidiopsis (Xiphidiopsis) compressa Jin, 2020, but differs from them by posterior process of male tenth abdominal tergite with apical area compressed and pointing to left in circa 90° and apex bluntly rounded; 1/3 apical area of right cercus curved anteriorly and dorsal surface bulging and ventral surface distinctly concave; apical area of subgenital plate with a pair of lateral lobes spoon-shaped; and posterior margin of female subgenital plate with a shallow emargination and lateral lobules triangular.
Etymology. The name of the new species is originated from the lateral lobules of male subgenital plate spoonshaped.
