Type material. Holotype, ♀, SE China, Fujian Province, Minqing, Fuzhou, 27.vi.2023, Liang guanghong. Paratype: 5♂ ♀, same label data as holotype.
Description. Holotype, ♀, length of fore wing 3.0 mm, of antenna 3.7 mm, and of body 4.2 mm (Fig. 2 A).
Head. Head width 1.5 × median length, roundly narrowed behind eyes (Fig. 3 B). Diameter of antennal socket about equal to distance between antennal sockets, 2.0 × distance between socket and eye (Fig. 3 B). Frons densely granulate, sometimes with fine striation (Fig. 3 B). Ocelli medium size, arranged in triangle with base 1.3 × its sides, POL 1.9 × Od, 0.65 × OOL (Fig. 3 B). Vertex transversely striate and with granulation between striae (Fig. 3 B). Temple finely striate and with finely reticulate (Fig. 3 B). Occipital carina complete dorsally, ventrally remaining separated from hypostomal carina (Fig. 3 B). Eye sparsely and shortly setose, 1.3 × as height as width (Fig. 3 B). Face width equal to eye height and 1.25 × height of face (Fig. 3 A). Face sparsely long setose, with two round concavities between antennal sockets and clypeus, small one above and bigger one below (Fig. 3 A). Clypeal suture distinct (Fig. 3 A). Clypeus semicircle, reticulate, 2.0 × as wide as high (Fig. 3 A). Malar space height 0.4 × eye height (Fig. 3 A). Malar suture absent (Fig. 3 A). Hypoclypeal depression round, its width 0.8 × distance from edge of depression to eye, 0.4 × width of face (Fig. 3 A). Antenna filiform, 30 antennomeres. Scape 2.2 × longer than maximum width. First flagellomere 4.0 × longer than its apical width, almost equal to second flagellomere (Fig. 2 A). Penultimate flagellomere 3.0 × longer than width, 0.5 × as long as first flagellomere, almost equal to apical flagellomere (Fig. 2 A).
Mesosoma. Length 1.8 × its height (Fig. 3 C). Pronotum weakly convex laterally with irregular wrinkles (Fig. 3 D). Mesoscutum highly and almost perpendicularly elevated above pronotum (Fig. 3 C). Notauli complete, shallow, with rough and irregular short wrinkles and its posterior half merges with a roughly wrinkled area at the posterior part of the middle lobe of mesoscutum (Fig. 3 D). Mesoscutum slightly convex, glabrous with fine reticulation, median portion with distinct striae and irregular sculpture between the striae (Fig. 3 D). Scutellar sulcus wide, with seven carinae, smooth between them, 0.4 × as long as scutellum (Fig. 3 C). Scutellum convex, with fine reticulation (Fig. 3 D). Mesopleuron with distinct striae and irregular sculpture between the striae in upper half portion, and granulate-coriaceous in lower half portion (Fig. 3 C). Sternauli deep and wide in medial portion of mesopleuron longitudinally (Fig. 3 C). Propodeum convex, without lateral tubercles, coarsely reticulate (Fig. 3 H).
Wings. Length of fore wing 3.2 × its maximum width (Fig. 3 E). Pterostigma 3.2 × as long as maximum width (Fig. 3 E). Vein r arising from basal 0.4 of pterostigma and 0.7 × as long as maximum width of pterostigma (Fig. 3 E). Vein 1-SR+M slightly curved. Vein 2-SR 2.4 × as long as r, 1.6 × as long as 3-SR, 1.7 × as long as m-cu, 0.7 × as long as 1-SR+M. Vein 3-SR slightly longer than r-m (Fig. 3 E). Vein M+CU1 slightly curved. Vein m-cu interfurcal. Vein cu-a postfurcal. Vein 1-CU1 0.15 × as long as 2-CU1. The first subdiscal cell open apical (Fig. 3 E).
Legs. Hind coxa 1.7 × as long as wide, with distinct baso-ventral protuberance, reticulation, with long setae; hind femur 3.3 × as long as wide, finely coriaceous, with sparsely short setae (Fig. 3 I); setae of hind tibia erect and 0.4 × as long as maximum width of tibia, finely coriaceous; hind tarsus 1.2 × as long as hind tibia; basitarsus 0.6 × as long as second-fifth segments combined; second segment of hind tarsus 0.6 × as long as basitarsus.
Metasoma. First tergite 0.8 × as long as its apical width, with medium-sized dorsope, with distinct longitudinal striae, and with minute transverse sculpture between striae (Fig. 3 G). Length of second and third tergite 1.2 × as long as first tergite (Fig. 3 G). Second tergite with shallow V-shape grooves, with distinct longitudinal striae, and with minute transverse sculpture between striae (Fig. 3 G). Basal 4/5 of third tergite with distinct longitudinal striae, apical 1/5 smooth and with shiny circular area (Fig. 3 G). Basal half of fourth tergite with distinct longitudinal striae, and with minute transverse sculpture between striae, medially only with distinct longitudinal striae, and apical smooth (Fig. 3 G). Basal half of fifth tergite finely granulate-reticulate. Remainder of metasoma smooth. Ovipositor sheath 0.6 × as long as body (Fig. 3 G).
Colour. Yellowish-brown to dark brown; palpi yellow; scutellum, metanotum, propodeum yellowish-brown; wing membrane hyaline, pterostigma brown, veins brownish to pale brown; antenna dark brown, but its basal six antennomeres yellow; legs brownish yellow; metasoma dark brown.
Paratype. Male. Body length 3.7 mm; fore wing length 3.0 mm; antenna length 4.3 mm, with 31 antennomeres. Hind wing with large brown pterostigma (Fig. 2 B).
Remarks. The new species have fore wing vein r-m present, thus differing from Leluthia (Euhecabolodes) transcaucasica (Tobias). It differs from Leluthia (Euhecabolodes) postfurcalis Belokobylskij & Maeto by vein m-cu of fore wing interfurcal, and mesopleuron without striate below sternauli.
Biology. So far only known to be the endoparasitoids of larvae of Phloeosinus sinensis Schedl, 1953 (Coleoptera: Buprestidae).
Distribution. China (Oriental).
Etymology. The specific name refers to Minqing, Fujian Province of China (Southeast of China) where this species was first found.
