description: Ocellarnaca virida sp. nov., Chinese name: Ḫefim̊⁂
(Figs. 1, 2, 3)
Description. Male. Body medium-sized and stout (Fig. 3A). Head. Face oval, nearly smooth (Figs. 1A; 3B). Eyes ovoid, slightly protruding forwards and outwards (Figs. 1A, B, C; 3B). Median ocellus large, lateral ocelli small (Fig. 1A). Fastigium verticis broad, width as about 1.5 times of antennal scapus, lateral margins lightly raised (Fig. 1C).
Wings. Tegmen reaching base of stretched hind tibia, and hind wing lightly longer than tegmen (Fig. 3A, B). Tegmen: subcosta anterior undivided, free throughout; subcosta posterior undivided in left tegmen while forking near apical area in right tegmen; radius releases radius sector near the middle, and forking more than once at subapex of tegmen; media anterior releases media posterior near apex of tegmen; cubitus anterior and cubitus posterior undivided, nearly parallel; with 3 anal veins (Fig. 2).
Legs. Fore coxa with 1 spine at anterior margin. Fore and middle femora unarmed; tibiae with 4 pairs of spines and 1 pair of apical spurs on ventral surfaces respectively; hind femur with 6 spines on internal margin and 5 spines on external margin of ventral surface; internal and external margins of hind tibia with 6–7 short spines on dorsal surface separately, as well as 1 pair of dorsal apical spurs and 2 pairs of ventral apical spurs.
Abdomen. Eighth abdominal tergite prolonged, twice as long as seventh abdominal tergite approximately (Fig. 1D); apical half of ninth abdominal tergite divided into a pair of lobate projections curved ventrad, the apical area with a short process which with small teeth on the subapex of inner surface (Fig. 1D, E, F). The processes visible when alive, but concealed beneath ninth abdominal tergite after being dried. Tenth abdominal tergite reduced. Subgenital plate wider than long, nearly rectangular; lateral margins feebly protruding outwards, basal margin almost straight; posterior margin with a pair of small processes which are slightly down-curved; styli coniform and apices rounded, lightly curved ventrad, inserted on lateral margins of apical area of subgenital plate (Fig. 1F).
Coloration. Body green. Eyes orange-red. Median ocellus and lateral ocelli similarly green as surrounding areas, the boundary indistinct; median ocellus with 3 white spots, while lateral ocelli with 2 oval white spots respectively (Figs. 1A, 3B). Apical area of mandible black (Fig. 1A). Tegmen and hind wing with veins light-yellow, while cells with dark brown spots in the middle and light bands along cross-veins (Figs. 2, 3A). Fore and middle tibiae with spines and spurs brown which apical areas light. Spines on hind femur and tibia with black apices.
Female. Unknown.
Specimen examined. Holotype: ♁, Luzhang, Lushui, Yunnan, 16 September, 2023, collected by Tao Zhang. Measurements (mm). Body length (distance from apex of fastigium verticis to posterior margin of ninth abdominal tergite): 24.4; pronotum length (distance from anterior to posterior margins of pronotum in the midline): 4.9; tegmen length (distance from base to apex of tegmen): 23.5; hind femur length (distance from base of hind femur to apex of genicular lobe): 13.3.
Discussion. This new species differs from the known species of the genus Ocellarnaca by green body and ocelli; the median ocellus and lateral ocelli similarly green as the surrounding areas, the boundary indistinct.
Etymology. The name of this new species is from its special body color that distinguishes it from other species of the genus Ocellarnaca, from Latin “ virid- ” (green).
Distribution. Yunnan (China).
