Lv, Wenqing, Li, Jicheng, Xie, Guanglin & Chang, Yanlin, 2024, Two new species of the genus Pseudokuzicus Gorochov, 1993 (Orthoptera: Tettigoniidae: Meconematinae) from China, Zootaxa 5496 (1), pp. 127-132 : 127-129

Pseudokuzicus (Pseudokuzicus) latus sp. nov., Chinese name ÎḬḢ*ª

( Fig. 1 ; Map 1 )

Description.

Male. Body small, relatively stout.

Head. Fastigium verticis conical, apex rounded, dorsal surface with a thin longitudinal furrow. Eyes nearly globular, projecting forwards. Apical segment of maxillary palpi slightly longer than subapical one, apex slightly swollen.

Thorax. Pronotum relatively short, anterior margin slightly protruding; posterior margin rounded, metazona slightly raised, lateral lobe longer than high, posterior area narrowing, without humeral sinus. Thoracic auditory spiracle open, oval. Legs. All femora unarmed on ventral surfaces, genicular lobes with apices rounded. Fore coxa with 1 spine; fore tibia with 4 pairs of short spines on ventral surface, tympana open on both sides, oval. Middle tibia with 4 pairs of short spines on ventral surface. Hind tibia with 17 – 20 spines on both sides of dorsal surface separately, apex with 1 pair of dorsal spurs and 1 pair of ventral spurs. Wings. Tegmen with apex slightly exceeding apical area of hind femur, anterior and posterior margins nearly parallel, apex rounded; hind wings slightly longer than tegmina.

Abdomen. Tenth abdominal tergite broad and short, the middle of posterior margin with a pair of ventrally curved processes; basal third of the process narrow, which parallel; other area curved outwards, broadened, apex rounded ( Fig. 1D, E ). Cercus slender and cylindrical, moderately incurved, basal area slightly stout, apex separated into dorsal and ventral branches, ventral branch slightly longer than dorsal one ( Fig. 1D, E ). Genitalia sclerotized, a pair of symmetric lamellar structures, with a longitudinal furrow in the middle, near apical area extended, the middle of apex with a small notch, inner apex with an acute process, outer apex rounded ( Fig. 1F, G ). Subgenital plate near rectangle, the middle of posterior margin slightly concave; styli small, conical, apices rounded, inserted on lateral margins of apex of subgenital plate ( Fig. 1C ).

Female. Unknown.

Coloration. Body multicolored. Frons brown; eyes dark brown; raised inner margin of antennal foveola black; dorsum of head with two pairs of longitudinal dark brown stripes, the central pair longer and the outer pair shorter. Flagellum of antenna with annular brown stripes. Disc of pronotum on lateral margins with a pair of longitudinal brown stripes, metazona dark brown, lateral lobe dark brown. Fore femora and tibiae, middle femora and tibiae, and outer surfaces of hind femora with irregular transverse brown stripes. Tegmina brown, with some irregular dark dark brown spots. Processes of tenth abdominal tergite dark brown. Basal half of cercus light yellowish brown, dorsal and ventral branches dark brown. Process of inner apex of genitalia dark brown.

Female. Unknown.

Material examined. Holotype: ♂, Wudaoxia, Baokang, Hubei, China, 8 August, 2020, coll. Guanglin Xie.

Measurements (mm). Body: ♂ 9.5; pronotum ♂ 3.6; tegmen: ♂ 10.6; hind femur: ♂ 8.5.

Distribution. China (Hubei).

Discussion. This new species is similar to Pseudokuzicus (Pseudokuzicus) platynus Di, Bian, Shi & Chang, 2014 , but it differs from the latter in: posterior margin on male tenth abdominal tergite with a pair of processes, basal third of the process thin; other area broadened, curved downwards and outwards ( Fig. 1D–E ); inner apex of genitalia with an acute process ( Fig. 1F–G ).

Etymology. The name of the new species is derived from tenth abdominal tergite of male with a pair of broad processes, Latin latus means broad.
