Pseudokuzicus (Similkuzicus) multispinus sp. nov., Chinese name 多刺似*ª

( Figs. 1 , 2B )

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 angularly rounded, metazona slightly raised, lateral lobe longer than high, posterior area narrowing, without humeral sinus. Thoracic auditory spiracle open. 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 23 – 25 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 posterior margin of tenth abdominal tergite, but not reaching apex of hind femur, anterior and posterior margins nearly parallel, apex rounded; hind wings slightly longer than tegmina. Abdomen. Tenth abdominal tergite with a pair of carinae near posterior margin, the middle of posterior margin slightly concave ( Fig. 1G–I ). Cercus with basal half cylindrical; the middle separated into dorsal and ventral branches, ventral branch short, incurved, apex acute; dorsal branch slightly longer than ventral one, upcurved, apex rounded ( Figs. 1C, G–I ; 2B ). Epiproct tongue-shaped ( Fig. 1H ). Genitalia sclerotized, trapezoidal, basal area wide; middle area slightly upcurved; one-third apical area upcurved, with two conical processes, which surfaces and apical areas with several stout and short spines ( Fig. 1F, I, J ). Subgenital plate relatively large, trapezoidal, basal area broad, narrowing, posterior margin with a triangular notch, lateral lobe slightly upcurved; styli absent ( Fig. 1C ).

Female. Appearance is similar to that of male. Pronotum slightly short. Cercus short, conical, apex acute. Ovipositor stout, moderately upcurved, dorsal and ventral margins smooth, dorsal valvulae with acute apices, ventral valvulae with hooked apices ( Fig. 1L ). Subgenital plate rectangular, broader than long, middle area of posterior margin slightly prominent ( Fig. 1K ).

Coloration. Body multicolor. Fron dark brown; eyes brown; raised inner margin of antennal foveola black; dorsum of head with two pairs of irregular longitudinal dark brown stripes, the central pair longer and the outer pair shorter. Flagella of antennae with annular brown stripes. Anterior area of pronotum with a pair of small black brown spots; metazona black, but some areas lighter, lateral lobe with irregular brown or dark brown stripes. Fore femora and tibiae, middle femora and tibiae, and outer surfaces of hind femora with irregular transverse brown stripes. Tegmina brown, with some irregularly dark brown spots. Basal half male cerci light yellowish brown, dorsal and ventral branches dark brown. Spines of apical area of genitalia brown.

Material examined. Holotype: ♂, Baishouzhen, Yongfu, Guangxi, China, 27 July, 2023, coll. Wenqing Lv. Paratype: 1♀, Jiuwanshan, Rongshui, Guangxi, China, 22 July, 2023, coll. Wenqing Lv. Other specimen: 1♀, Jiuwanshan, Rongshui, Guangxi, China, 22 July, 2023, coll. Wenqing Lv.

Measurements (mm). Body (distance from apex of fastigium verticis to posterior margin of tenth abdominal tergite): ♂ 7.8, ♀ 9.5–9.8; pronotum (distance from anterior to posterior margins of pronotum in the midline): ♂ 5.5, ♀ 3.9–4.3; tegmen (distance from base of tegmen to the apex): ♂ 7.8, ♀ 8.2–8.8; hind femur (distance from base of hind femur to apex of genicular lobe): ♂ 10.2, ♀ 10.0–10.5; ovipositor (the distance from the base of subgenital plate to the apex of ovipositor): 5.8–6.2.

Distribution. China (Guangxi).

Discussion. This new species resembles Pseudokuzicus (Similkuzicus) quadridentatus Shi, Mao & Chang, 2007 , but it differs from the latter in: one-third apical area of genitalia separated into two conical processes, which surfaces and apical areas with several stout and short spines ( Figs. 1F, I–J ; 2C–E ); metazona of pronotum black.

Etymology. The name of the new species is derived from one-third apical area of male genitalia with multiple spines, Latin multi- means multiple, spin- means spine.
