Type material.

Holotype, ♀ ( NIBR), South Korea, Inje-Gun , Bukmyeon, Hangyeri, 38°08'46.5"N, 128°15'47.5"E, 9-16. IX. 2017 (Malaise trap), J.H. Sohn. GenBank accession no. MW 376065 .

Comparative diagnosis.

Differs from other species of Cratospila by having the apical half of ♀ antenna with 8-13 white segments combined with a relatively wide face (1.2 times its height; 0.9-1.1 times in other species). Closely related to C. albifera sp. nov.; for differences, see they key above.

Description.

Holotype, ♀; length of body in lateral view 3.2 mm (Fig. 3A ), length of antenna 4.2 mm (apex of antenna missing) and length of fore wing 2.9 mm.

Colour: head (Fig. 3D ) orange-yellow; with at least 4 flagellomeres of antenna white (apex of antenna missing); mandible whitish orange. First tergite dark brown and mesonotum entirely reddish brown.

Head: width 1.4 times median length in dorsal view. Antenna (Fig. 3B ) twice as long as body in female, 24 segmented (but apex of antenna missing). First flagellomere 1.8 times longer than second. Compounded eye slightly oval, 1.1 times as long as wide in lateral view. Width of face (Fig. 3E ) 0.9 times its height from ventral rim of antennal sockets to upper margin of clypeus. Eye in dorsal view 1.7 times as long as temple. Ocello-ocular line 1.8 times longer than diameter of anterior ocellus; OOL: AOL: POL = 10: 3: 8. Stemmaticum concave. Vertex smooth, glossy, and with brown line. Mandible with three teeth; second tooth prominent, with black tip. Maxillary palp about equal length of mesosoma.

Mesosoma (Fig. 3G ): 1.5 times longer than wide in dorsal view. Mesoscutum with medio-posterior depression and setae near it; notauli on middle of mesoscutum, comparatively coarsely crenulate, not reaching medio-posterior depression; scutellar sulcus with six carinae; metanotum sculptured; small bump in hind coxa adjacent to metapleuron. Propodeum (Fig. 3H ) 0.8 times longer than width, anterior half of propodeum less sloping; lateral view of propodeum is bent; precoxal sulcus (Fig. 3F ) deep and distinct, consist of about nine grooves. Fore wing (Fig. 3C ) 2.5 times as long as wide; pterostigma long and narrow, 4.1 times longer than wide; vein r of fore wing 3.2 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 = 33: 9: 23; first subdiscal cell of fore wing ca 7.5 times longer than wide Hind wing vein M+CU: vein 1-M = 66: 7

Leg: hind coxa compressed and grooved; hind coxa 1.7 times longer than hind trochanter; hind femur 0.9 times longer than hind tibia; hind tibia 1.1 times longer than hind tarsus.

Metasoma: first tergite striate and narrow, reddish brown, 2.8 times longer than apical width; T 1: T 2 = 59:24. Setose part of ovipositor sheath (Fig. 3I ) 0.4 times as long as mesosoma, 0.5 times as long as hind tibia and with long setae (Fig. 2F ).

Male. Unknown.

Distribution.

South Korea.

Etymology.

Named after its yellowish head: " Cratospila luteocephala " is derived from “luteus” (Latin for yellow) and “cephalus” (Latin for head).
