Type material.

Holotype • ♀ ( NIBR), South Korea, Mt. Kalbong , Gyeongban-ri, Gapyeong-eup, Gapyeong-gun, Gyeonggi-do, 37°51'10.9"N, 127°26'27.4"E, 05.VI.2020, Sohn. GenBank accession no. PP 587254.

Comparative diagnosis.

This new species is close to P. chasanica Belokobylskij, 1998 because of sharing second flagellomere 1.4–1.5 × longer than first flagellomere (same length in P. chasanica ). Width of head 1.8 × its median length in dorsal view (1.8–2.0 × in P. chasanica ). In mandible, first and second tooth not separated distinctly. Hind femur 5.0–5.5 × as long as wide. The new species differs from P. chasanica by head and mesosoma black (head and mesosoma yellowish brown in P. chasanica ) and thick and short tarsal claws (tarsal claws thin and relatively long in P. chasanica ). The new species can be recognised by its comparatively long ovipositor sheath (1.2 × longer than mesosoma and 1.4 × longer than hind tibia) and rugose median part of face rugose.

Description.

Holotype, ♀, body 2.5 mm in lateral view, fore wing 2.5 mm, ovipositor sheath 1.0 mm, antenna 3.9 mm.

Head: Width of head 1.8 × its median length in dorsal view (Fig. 4 D ). Antenna with 26 antennomeres and 1.6 × as long as fore wing or body. First flagellomere 3.2 × longer than wide (Fig. 4 K ). Second flagellomere 1.4 × longer than first and 4.8 × longer than wide. Middle of antenna segment 3.1 × longer than width. Eye slightly oval, in lateral view 1.1 × as long as wide. Minimum width of face (Fig. 4 E ) 1.3 × its height; face with setose, median part of face rugose. Eye in dorsal view 2.6 × as long as temple. Ocello-ocular line ( OOL) 4.2 × longer than diameter of anterior ocellus; OOL: antero-posterior ocellar line ( AOL): postero-ocellar line ( POL) = 27: 8: 9. Vertex smooth and glabrous, short longitudinal groove present POL. Width of clypeus 2.6 × its maximum length. Mandible (Fig. 4 L ) 1.8 × longer than wide, wide with first tooth curved upward and broad; second tooth long and broad, 1.3 × longer than first tooth, tip of second tooth reddish brown; first and second tooth not separate distinctly; third tooth as long as first tooth.

Mesosoma: In dorsal view mesosoma 1.9 × longer than wide and 1.4 × longer than high in lateral view. Mesoscutum (Fig. 4 F ) with small and round medio-posterior depression and glabrous; notauli distinct anteriorly to half of mesoscutum, not reaching to medio-posterior depression; mesoscutum few setae along notauli; scutellar sulcus with one strong carina; apical part of mesopleuron and metapleuron with few setae, mesopleural groove sculptured. Precoxal sulcus distinct, reaching anterior and posterior edges of mesopleuron. Maximum length of propodeum (Fig. 4 F ) 0.5 × its width; longitudinal carina present on propodeum, posterior part of propodeum with small areola, not reaching to half of propodeum. In lateral view, metanotum not protruding medio-dorsally (Fig. 4 G ). Fore wing (Fig. 4 C ) 2.4 × as long as wide; pterostigma broad, 4.3 × longer than wide; vein r of fore wing 1.7 × longer than wide; vein SR 1 2.1 × longer than vein 3 - SR; vein 3 - SR 1.5 × longer than 2 - SR; second submarginal cell 2.6 × longer than its medium length; 3 - SR: r: SR 1 = 13: 1: 27 first discal cell of fore wing as long as wide medially. Hind wing: vein M + CU + 1 - M: vein 1 r-m = 4: 1.

Leg: Hind femur 5.4 × as long as wide and 0.7 × as long as hind tibia; hind tibia 8.8 × longer than wide; hind tibia 0.8 × as long as hind tarsus.

Metasoma: First tergite (Fig. 4 H ) rugose 1.4 × longer than its apical width. Setose part of ovipositor sheath (Fig. 4 I ) 1.2 × longer than mesosoma, 1.4 × longer than hind tibia and 0.4 × as long as fore wing.

Color: Body (Fig. 4 A ) black; metasoma (except first tergite) and antenna dark brown but basal part of antenna and legs yellowish brown.

Etymology.

The specific name tanycauda is an adjective, named after the long ovipositor sheath; tanyo is Greek for stretched out, cauda is Latin for tail.
