Etymology.

The specific name is derived from the type locality.

Holotype. Female, CHINA: Laoshan, Qingdao, Shandong Province, 12 June 2017, IT. Paratype. 1 female, same data as holotype except 26 June 2017.

Diagnosis.

Propodeum rather long. Metasomal tergites 3-6 with even dense and unclear punctures. Second metasomal tergite ( Figs 8 , 9 ) slightly longer than its apical width. Ovipositor sheath 0.7 × as long as hind tibia. Apical portion of dorsal valve of ovipositor ( Fig. 10 ) with 6 small tubercles. Face ( Fig. 2 ) with large lateral white spots. All tergites ( Fig. 8 ) with posterior white bands.

Description.

Female. Body length 11.0 to 11.9 mm. Fore wing length 7.0 to 7.4 mm. Ovipositor sheath length 2.3 to 2.4 mm.

Head.

Inner margins of eyes slightly convergent ventrally. Face ( Fig. 2 ) medially slightly convex, 1.4 × as wide as long, with dense, indistinct punctures and opalescent hairs; lateral portion shagreened; upper margin with a small median tubercle. Clypeus 1.9 × as wide as long, slightly evenly convex; dorsal portion with dense punctures, ventrally smooth, ventral margin almost truncate, with a strong blunt tubercle medially ( Fig. 2 ). Labrum almost semicircular, ventral margin with long brown hairs. Mandible with dense punctures and yellowish white hairs, upper tooth approximately as long as lower tooth. Malar area finely shagreened. Malar space 0.7 × as long as basal width of mandible. Gena with distinct punctures ( Fig. 3 ). Vertex ( Fig. 4 ) with dense distinct punctures. Postocellar line 0.8 × as long as ocular-ocellar line. Frons with a medio-longitudinal carina. Head behind the eyes in dorsal view weakly narrowed. Antenna with 32 flagellomeres. Ratios of lengths from first to fifth flagellomeres: 1.9:1.7:1.6:1.2:1.0. First flagellomere 8.0 × as long as wide. Occipital carina complete, reaching hypostomal carina distinctly above base of mandible. Hypostomal carina distinctly elevated.

Mesosoma.

Anterior portion of pronotum with dense yellowish white hairs, lateral concavity ( Fig. 6 ) wide and shallow, subdorsal posterior portion with oblique rugae, upper and lower portions with dense indistinct punctures. Epomia distinct. Mesoscutum ( Fig. 5 ) shiny, with dense punctures, postero-median portion with short transverse rugae. Notaulus evident on anterior half of mesoscutum. Scutoscutellar groove wide, with weak indistinct longitudinal rugae. Scutellum slightly convex, with sparse fine punctures. Postscutellum transversely slightly convex, shiny. Mesopleuron ( Fig. 6 ) rugose, almost flat, with dense indistinct punctures; upper anterior portion beneath subalar prominence with short indistinct transverse rugae. Epicnemial carina weak, 0.8 × as long as mesopleuron. Speculum almost smooth, with sparse fine punctures. Sternaulus 0.4 × as long as length of mesopleuron. Metapleuron ( Fig. 6 ) evidently rugose, with dense indistinct punctures and short hairs. Hind femur 5.4 × as long as maximum width. Ratio of length of one to fifth hind tarsomeres 6.3:2.9:1.8:1.0:1.8. Wings slightly grey, hyaline. Fore wing with vein cu-a basad of Rs & M by 0.3 times length of cu-a. Areolet receiving vein 2m-cu at its middle ( Fig. 1 ). Vein 3rs-m approximately parallel to 2rs-m. Hind wing cu-a intercepted above middle. Propodeum rather long. Anterior and posterior transverse carinae of propodeum ( Fig. 7 ) complete, median portions weakly bent forward. Area basalis shiny, lateral carinae distinct, strongly convergent caudally. Area externa shiny, anterior portion smooth, posterior portion with distinct punctures. Rest portions of propodeum densely irregularly reticulate, with dense short grey-white hairs. Propodeal spiracle small, almost circular.

Metasoma

( Figs 8 , 9 ). First tergite 2.2 × as long as apical width; petiole and anterior portion of postpetiole almost shiny, with fine punctures; apical portion of postpetiole smooth, shiny, posteromedian portion distinctly convex. Median dorsal carina almost reaching to spiracle; dorsolateral and ventrolateral carinae complete. Tergites 2 to 6 with even dense distinct punctures. Second tergite ( Figs 8 , 9 ) slightly longer than its apical width. Third tergite 0.6 × as long as apical width. Ovipositor sheath 0.7 × as long as hind tibia. Ovipositor ( Fig. 10 ) compressed; apical portion of dorsal valve with 6 small tubercles; apical portion of ventral valve with 13 edges.

Coloration

( Fig. 1 ). Black, except for the following. Large lateral spots of face, main portion of clypeus, labrum, median portion of mandible, median portions of maxillary and labial palpi, ventral profiles of flagellomeres (5)6 to 10(11), dorsoanterior portion of pronotum, scutellum, postscutellum, tegulae, subalar prominence, apex of fore coxa, ventral profile of mid coxa, apical half of hind tarsomere 1, hind tarsomeres 2-4, basal half of hind tarsomere 5, apical bands of all tergites white. Apical portions of fore femur, fore tibia and tarsus, ventral profiles of mid and hind femora and tibiae, ventral profiles of hind coxae red brown. Basal portion of fore femur, dorsal profiles of mid and hind femora, tibiae, hind coxa, apical portion of hind tibia brownish black. Lateral profile of first tergite slightly brown. Pterostigma and wing veins blackish brown.

Remarks.

This new species is similar to Hoplocryptus alboanalis (Uchida, 1952) by the characters: Clypeus with a strong smooth blunt tubercle medially; notaulus strong on anterior half of mesoscutum. anterior and posterior transverse carinae of propodeum complete; ventral valve of ovipositor with strong edges; mesosoma almost entirely black; median portion of flagellum, at least ventral profiles, white; and can be distinguished from the latter by the following combination of characters: Fore wing vein cu-a basad of Rs & M by about 0.3 times length of cu-a. Posterior transverse carina of propodeum ( Fig. 7 ) evenly weakly bent forward. Face with large lateral white spots. Clypeus largely white. Ventral profile of hind coxa red brown, dorsal brownish black. Posterior portions of tergites with relative wide transverse white bands. Hoplocryptus alboanalis : Fore wing vein cu-a opposite Rs & M. Posterior transverse carina of propodeum almost sharply bent forward. Face, clypeus and hind coxa entirely black. Tergites entirely black.
