An, Meng, Chen, Chun & Shi, Fuming, 2023, One new genus and species of the tribe Meconematini (Orthoptera: Tettigoniidae: Meconematinae) from Guangxi, China, Zootaxa 5227 (3), pp. 398-400 : 398-400

Guangxia longlina An, Chen & Shi , sp. nov.

Description. Male. Body small, thin. Fastigium verticis conical, apex rounded, with longitudinal sulcus on dorsal surface. Compound eyes globular, protruding forward. Frons slightly sloping backward. Apical segment of maxillary palpus approximately equated in length with subapical segment, apex swollen and rounded.

Pronotum slightly elongate backward, with median carina, anterior margin nearly straight, posterior margin rounded; lateral lobe longer than deep, humeral sinus absent. Thoracic auditory spiracle exposed, oval.

Tegmina only reaching apex of abdomen, tapering, apices slightly and obliquely truncated; hind wings slightly shorter than tegmina.

All femora without spines on ventral surfaces. Procoxa with 1 spine; protibia with 6 spines on each side of ventral surface; tibial tympana oval, open on both sides. Mesotibia with 5–6 spines on each side of ventral surface. Genicular lobe of postfemora with apex rounded; posttibia with 23–27 spines on both sides of dorsal surface, bearing a pair of dorsal apical spurs and 2 pairs of ventral apical spurs.

Posterior margin of male tenth abdominal tergite concave, with a pair of posterior processes branching from base to apex. Epiproct triangular. Cercus with 1 inner spinous process on middle area of ventral surface; apex incurved, with 2 branches, dorsal one longer than ventral one. Genitalia with dorsal and ventral lobes; dorsal lobe positioned between the cerci, elongated, with dorsal surface concave, apex rounded and slightly downcurved; ventral lobe positioned between cerci and subgenital plate, basal 2/3 extending into a semicircle on both sides, apex nearly rectangular, posterior margin upcurved, with middle area concave. S ubgenital plate nearly rectangular, longer than wide. Styli short, positioned on apex of subgenital plate.

Coloration. Body slightly brown or slightly green. Antennae brown, with sparse black rings. Compound eyes brown. Tegmina with black spots. Apex of genicular lobe black.

Female. General appearance is similar to that of male. Cerci conical, apices acute. S ubgenital plate nearly rhombic, with posterior margin rounded. Ovipositor slightly upcurved, dorsal and ventral margins smooth, ventral valvulae with apices hooked.

Material examined. Holotype: ♁, Jinzhongshan, Longlin, Guangxi, China, 21 August, 2022, coll. Meng An. Paratypes: 3♁ 3♀, Jinzhongshan , Longlin, Guangxi, China, 17 August, 2022, coll. Meng An ; 1♁ 1♀, Jinzhongshan , Longlin, Guangxi, China, 18 August, 2022, coll. Meng An ; 4♀, Jinzhongshan , Longlin, Guangxi, China, 19 August, 2022, coll. Meng An ; 3♁ 1♀, Jinzhongshan , Longlin, Guangxi, China, 20 August, 2022, coll. Meng An ; 3♁ 3♀, the other data as holotype .

Measurements (mm). Body: ♁7.0–8.3, ♀ 7.3–8.9; pronotum: ♁3.9–4.2, ♀ 3.9–4.0; tegmen: ♁6.5–7.1, ♀ 7.0–7.9; postfemora: ♁8.5–9.0, ♀ 9.0–10.0; ovipositor: ♀ 8.0–9.8.

Distribution. China (Guangxi).

Etymology. The name of the new species is derived from its type locality (Longlin, Guangxi, China).

Discussion. The new species resembles Aphlugiolopsis Wang, Liu & Li, 2015 , but differs in: posterior margin of male tenth abdominal tergite concave, with a pair of posterior processes; styli positioned on apex of subgenital plate.
