Paratypes . ♂ , same data as in holotype . 3♂ , same location as in holotype , 20-VI-2022 , coll. local villager . Description. Small species. Fastigium of vertex about 1.8 times as broad as scape; scape about 0.7 times as long as eye; pedicel as long as scape ( Fig. 1 AB, 2A). Eyes ovoid; ocellus distinct ( Fig. 1A , 2A ). Anterior margin of pronotum convex in the middle, posterior margin slightly curved; lateral lobes longer than deep, ventral margin slightly incurved ( Fig. 1 BC, 2BCDE). Fore coxa with a spine at fore margin ( Fig. 2H ); fore and mid femora unarmed ( Fig. 2 HIJK); fore and mid tibiae dorsally unarmed ( Fig. 2 HIJK); fore tibiae ventrally with 4 pairs of internal spines and one pair of smaller spurs ( Fig. 2 HI); mid tibiae ventrally with 4 pairs of spines and one pair of smaller spurs ( Fig. 2 JK); hind femora ventrally with 9–10 internal spinules and 9–11 external spinules ( Fig. 2 LM); hind tibiae dorsally with 6 internal spinules, 5–6 external spinules and one pair of apical spurs, ventrally with one preapical spine and 2 apical spurs ( Fig. 2 LM). Tegmina reaching posterior margin of ninth abdominal tergite; hind wings as long as tegmina ( Fig. 1E , 2G , 3 ABC). C, Sc and R veins undivided, free throughout; M with a single branch that forks at basal third into two veins, MA and MP; CuA and CuP undivided, free throughout; with five Anal veins ( Fig. 1E , 2G ). Female. Seventh abdominal sternite broad, surface in middle of basal area with a pair of greatly projected lateral lobes, pointing to the posterior of the body, between them with a rather wide V-shaped groove ( Fig. 1D ). Subgenital plate transverse, rather short especially in middle and forming a bilobular structure, pressed against seventh sternite with basal margin concave. Ovipositor curved upward strongly, dorsal margin and ventral margin smooth, apex acute ( Fig. 1F ). FIGURE 1. Morphological structures of female Larnaca ( Larnaca ) lieyongzhou sp. nov.

Eighth abdominal tergite rather prolonged; ninth abdominal tergite curved downwards, furrowed along midline into 2 lobes, apical area prolonged into a long spiniform process with finely granular surface which greatly crossed at midline and pointing inside ( Fig. 2F ). Subgenital plate broader than long, anterior margin straight, posterior margin bi-globular with an obviously V-shaped median incision; styli conical and curved inwards, inserted in posterior area of lateral margin of subgenital plate ( Fig. 2F ). Coloration. Upper and front side of head generally black, transit to red around side-hind margin area when alive; ocellus yellowish orange; middle part of face red when alive; mandibles black. Pronotum generally black, with four pairs of whiteish triangular-shaped dots; two larger and wider pair close to frontal, one pair around middle area, and largest pair close to lateral margin (male specimen 2 # ); the size, shape, and color of dots are not stable, vary greatly among individuals. For tegmen, a black dot presents around basal area of C and M veins, brownish yellow for most of the middle part, terminus transparent, veins at terminal area black. All upper sides of femora concolorous with abdominal side of thorax, bottom sides orange with black joints; fore and mid tibiae black, while hind tibiae white with black spines; all tarsus black. Ovipositor orange-brown. Measurements (mm). Body (from head to tip of abdomen): 21.26–22.75; pronotum: 5.62–6.23; tegmen: 15.14–16.69; hind wing: 16.46–16.71; fore femora: 7.93–8.10; median femur: 6.85–7.07; hind femur: 11.97–12.09; fore tibiae: 8.76–8.96; median tibiae: 8.02–8.49; hind tibiae: 12.29–13.15; ovipositor: 10.33. Notes. This species is similar to Larnaca ( Larnaca ) tenuis Ingrish, 2018 . However, L. lieyongzhou sp. nov. can be distinguished by the following characteristics: the lobes on female 7 th abdominal sternite is much longer and more projected, and the cavity between them is shallower and more V-shaped, while for L. tenuis the cavity is deeper and U-shaped. In addition, the size, shape, and color of dots vary greatly among individuals, and such difference may not be regarded as the characteristic of different species in the genus Larnaca . Etymology. This species is named after the Chinese name of Kaiou Retsu, a main character from the famous manga series Baki . As a warrior who obtains not only outstanding battling technique but also nice and just personality, Kaiou Retsu is widely revered by readers. Distribution. Guangxi , China . Known only from the type locality. ( Fig. 4 )
