Type material.

Holotype, ♀ ( NIBR), South Korea, DMZ Botanical Garden , Mandae-ri , Haean-myeon , Yanggu-gun, Gangwon-do, 38°15'09.3"N, 128°06'40.6"E, 20. VI.-4.VII.2017 , H. T. Shin, S.J. Kim. GenBank accession no. MW 376066 .

Comparative diagnosis.

Differs from other new species herein by the short vein r of the fore wing (ca as long as wide; 2-5 times in other species). Unfortunately, the antenna is incomplete but the COI analysis places it in the group of derived Cratospila species having the apical half of the ♀ antenna with 8-13 white segments (Table 1 ). Closely related to C. ejuncida sp. nov.; for differences, see the key above.

Description.

Holotype, ♀; length of body in lateral view 2.5 mm (Fig. 4A ), length of antenna 2.8 mm (but apex of antenna missing) and length of fore wing 2.4 mm.

Colour: head (Fig. 4D ) entirely black; mandible yellowish brown. Antenna entirely dark brown (but apical segments missing). First tergite dark brown and mesonotum entirely black.

Head: width 1.6 times median length in dorsal view. Antenna (Fig. 4B ) 1.1 times longer than body in female, 23-segmented (apex of antenna missing). First flagellomere 1.7 times longer than second. Compounded eye slightly oval, 1.2 times as long as wide in lateral view. Width of face (Fig. 4E ) 1.1 times its height from ventral rim of antennal sockets to upper margin of clypeus. Face with dense setae. Eye in dorsal view 1.9 times as long as temple. Ocello-ocular line 2.0 times longer than diameter of anterior ocellus; OOL: AOL: POL = 5: 3: 7. Stemmaticum concave. Mandible with three teeth; third tooth bent outside.

Mesosoma (Fig. 4G ): 1.9 times longer than wide in dorsal view with medio-posterior depression and setae near it; notauli on middle of mesoscutum narrowly crenulate, not reaching medio-posterior depression; scutellar sulcus with six carinae; metanotum sculptured; small bump in hind coxa adjacent to metapleuron; metapleuron with long setae. Propodeum (Fig. 4H ) 0.8 times longer than width, more extensively rugose medially; lateral view of propodeum not bent; precoxal sulcus (Fig. 4F ) completed with 10 grooves; scutellum with setae partially. Fore wing (Fig. 4C ) 2.9 times as long as wide; pterostigma long and narrow, 3.2 times longer than wide; vein r of fore wing 1.5 times longer than wide; vein 2-SR slightly bent; vein 2-SR+M and r-m not sclerotized; vein 2-SR: vein r: vein 3-SR = 27: 5: 20; first subdiscal cell of fore wing ca 6 times longer than wide; second submarginal cell robust. Hind wing vein M+CU: vein 1-M = 39: 4.

Leg: hind coxa compressed and grooved; hind coxa 1.4 times longer than hind trochanter; hind femur 0.6 times longer than hind tibia; hind tibia 1.2 times longer than hind tarsus.

Metasoma: first tergite striate and narrow, reddish brown, 2.7 times longer than apical width; T 1: T 2 = 45:19. Setose part of ovipositor sheath (Fig. 4I ) 0.3 times as long as mesosoma, 0.4 times as long as hind tibia and with long setae.

Male. Unknown.

Distribution.

South Korea

Etymology.

Named after the short second submarginal cell of the fore wing: " syntomus " is Greek for shortened.
