Type material.
Holotype • ♀ (NIBR), South Korea, Mt. Odae, Jinbu-myeon, Pyeongchang-gun, Gangwon-do, 37°45'54.7"N, 128°34'13.8"E, 15.IX.2020, Ju-Hyeong Sohn leg. GenBank accession no. PP 587250.
Comparative diagnosis.
The new species is similar with P. telengai Belokobylskij, 1998, but recognizable the third tooth distinctly and acutely protruding as the first one (only second tooth narrow and acute in P. telengai), first flagellomere 4.2 × longer than wide (2.8–3.0 × in P. telengai) and hind femur 4.2 × longer than wide (4.7–5.0 × in P. telengai).
Description.
Holotype, ♀, body 2.8 mm in lateral view, fore wing 2.6 mm, ovipositor sheath 1.4 mm in lateral view, antenna 3.4 mm (apical part of antennae missing).
Head: Width of head 1.5 × its median length in dorsal view (Fig. 1 D). Antenna with 25 antennomeres (terminal antennomere missing), first flagellomere 4.2 × longer than wide (Fig. 1 K), second flagellomere 1.5 × longer than first antennomere and 5.2 × longer than wide. Medial antennal segments (18 th segment) 2.3 × longer than wide. Eye slightly oval, in lateral view 1.2 × as long as wide. Minimum width of face (Fig. 1 E) 1.2 × its height; face rugose with setose. Eye in dorsal view 1.8 × as long as temple. Ocello-ocular line (OOL) 4.8 × longer than diameter of anterior ocellus; OOL: antero-posterior ocellar line (AOL): postero-ocellar line (POL) = 30: 7: 10. Vertex smooth and glabrous. Width of clypeus 2.3 × its maximum length. Mandible (Fig. 1 L) 1.8 × longer than wide, wide with first tooth curved; second tooth narrow and long, 1.2 × longer than first tooth, tip of second tooth reddish brown; third tooth (as first) distinctly acutely protruding; carina on third tooth distinct.
Mesosoma: In dorsal view mesosoma 2.2 × longer than wide 1.6 × longer than high in lateral view. Mesoscutum (Fig. 1 F) with small and round medio-posterior depression and glabrous; notauli impressed anteriorly, not reaching to medio-posterior depression; scutellar sulcus with one carina; apical part of mesopleuron and metapleuron without setae, posterior mesopleural groove sculpted. Precoxal sulcus distinct, reaching anterior and posterior edge of mesopleuron. Maximum length of propodeum (Fig. 1 F) 0.5 × as long as its width, largely sculpted; posterior part of propodeum with small areola, not reaching middle of propodeum. Metanotum not protruding medio-dorsally in lateral view (Fig. 1 G). Fore wing (Fig. 1 C) 2.6 × as long as wide; pterostigma widened medially 5.1 × longer than wide; vein r of fore wing 4.0 × longer than wide; vein SR 1 1.8 × longer than vein 3 - SR; vein 3 - SR 1.5 × longer than 2 - SR; second submarginal cell long and narrow, 2.7 × longer than its medium length; 3 - SR: r: SR 1 = 12: 3: 22; first discal cell of fore wing 0.8 × longer than wide in median length; first discal cell of fore wing 1.1 × as longer medially than wide. Hind wing: vein M + CU + 1 - M: vein 1 r-m = 4: 1.
Leg: Hind femur 4.2 × longer than wide and 0.7 × as long as hind tibia; hind tibia 11 × longer than wide; hind tibia as long as hind tarsus.
Metasoma: First tergite (Fig. 1 H) sparsely rugose, 1.5 × longer than its apical width. Setose part of ovipositor sheath (Fig. 1 I) 1.4 × longer than mesosoma and 1.9 × longer than hind tibia.
Color: Body (Fig. 1 A) dark brown, antenna dark brown, but anterior yellowish brown; metasoma dark brown; legs yellowish brown; first tergite brown.
