T 2 ‒ T 7 impunctate. The new species runs close to D. jungi Ma in the key to Asian and Oceanic Dasyproctus (Leclercq 2015) in having, in females: vertex with sparse, small punctures, and longitudinal pit near inner eye margin; gena sparsely punctate, with dense short silvery setae; mandible yellow basally; anterior carina of pronotal collar laterally bending towards insertion of fore coxa, medially parallel to anterior margin of scutum; scutum with dense, small punctures; pronotal collar distinctly notched medially; metanotum with longitudinal striae mixed with small punctures; tegula testaceous; propodeum with coarse, oblique rugae dorsally, arched striae laterally, Y-shaped furrow on posterior aspect; T 1 immaculate; T 2 with large, round depression at base; T 2 ‒ T 4 with largely, brightly yellow maculae. In males: clypeal with free margin truncate medially; mandible sometimes with small yellow spot at base; IOC distinct; gena sparsely punctate; flagellomeres II ‒ IV cylindrical; pedicel and flagellum black; scutum with sparse, small punctures; dorsal surface of fore tibia yellow; T 1 longer than hind femur; T 2 with large, round depression at base. However, it differs from the latter in having, in females: head rectangular; flagellum I brownish; mandible reddish to black apically; vertex with longitudinal, shallow pit near inner eye margin; hind tibia yellow postero-dorsally except apex, with hook-shaped carina postero-dorsally, and brown macula antero-dorsally; all tarsi brown except tarsomere 1 yellow basally; T 2 with shallow depression basally; pygidial plate reddish brown; T 5 and pygidial plate with brown-yellow setae. In males: mandible entirely black excepting small yellow spot at base; scape except dorsal surface, pronotal collar, pronotal lobe, dorsal surface of fore tibia yellow, yellow band on dorsal surface of mid and hind tibiae medially; petiole dorsally 2.5 × as long as wide; T 2 with shallow depression basally; T 5 with brightly yellow maculae, T 6 with largely, brightly yellow band anteriorly.	en	Pham, Phong Huy (2022): Taxonomic studies on Dasyproctus Lepeletier & Brullé (Hymenoptera: Crabronidae) from North Vietnam with description of two new species.

Brown to black-brown are: flagellum I, tegula, pedicel, pygidial plate, ventral surface of all tibiae, and all tarsi except tarsomere 1 basally. Head (Figs 49 & 52): In frontal view nearly rectangular, about 1.5 × as long as wide; mandible tridentate apically, with small tooth on inner margin; clypeus covered with dense silvery setae, slightly beveled, free margin slightly indented medially, blunt tooth on each side of free margin, longitudinal median carina reaching free margin; antennal sockets contiguous with one another and with inner eye margin; scape with two longitudinal, parallel carinae ventrally, length of scape 2.2 × distance between eyes at base of antennal socket; flagellum covered with thick short setae, flagellomere I as long as II, relative lengths of scape: pedicel: flagellomere I = 30: 5: 9; scapal basin with thick, adpressed silvery setae; IOC conspicuous; frons without furrow above IOC, densely punctate; OOD 1.18 × POD; vertex with sparse, small punctures, and well-imprinted supra-orbital fovea; frons and vertex covered with short brownish setae; gena sparsely punctate, with dense short silvery setae. Mesosoma (Figs 50 & 53): Anterior carina of pronotal collar laterally bending towards insertion of fore coxa, medially parallel to anterior margin of scutum; pronotum conspicuously striate laterally; pronotal collar distinctly notched medially; scutum with dense, small punctures, and a series of short rugae posteriorly; scutellum and mesopleuron with sparse, fine, small punctures; metanotum with longitudinal striae mixed with small punctures; mesopleuron matt; metapleuron shining, with conspicuous, oblique rugae; propodeum with coarse, oblique rugae dorsally, arched striae laterally, Y-shaped furrow on posterior aspect. Mesosoma with white setae, sparse on scutum and denser on propodeum; hind tibia with hook-shaped carina postero-dorsally. Metasoma (Figs 51 & 54): petiolate; T 1 immaculate, with apical width about 2.6 × its basal width dorsally, length of T 1 equal to that of hind femur, 1.4 × that of T 2 ‒ T 4 combined; T 2 with large, round depression at base; T 1 ‒ T 5 with sparse, fine, small punctures; T 2 ‒ T 5 with large maculae, these on T 2 smaller than those on T 3 and T 4, these on T 3 equal to those on T 4; pygidial plate with coarse, dense punctures, conspicuously narrowed and gutterlike apically. Metasoma with whitish brown setae except T 5 and pygidial plate with brown-yellow setae. Male, paratype (Figs 55 ‒ 61): Body length 6.5 ‒ 7.0 mm, forewing length 4.5 ‒ 5.0 mm. Structure as in female, but differing as follows: Colour. Scape yellow except inner lateral sides; mandible black, sometimes with small yellow spot at base; scutellum black except small yellow spot antero-laterally; mesopleuron sometimes with small yellow spot; small yellow spot on fore femur apically; dorsal surface of fore tibia yellow; yellow band on dorsal surface of mid and hind tibiae medially; large spot on dorsal surface of hind tibia; tegula testaceous; ventral surface of all tibiae blackish brown; T 7 and all tarsi dark brown. Head (Figs 55 & 58): clypeus with free margin truncate medially; mandible bidentate apically; flagellomeres II ‒ IV cylindrical; frons densely, largely punctate, with shallow, narrow furrow above IOC. Mesosoma (Figs 56 & 59): Anterior carina of pronotal collar laterally curving towards pronotal lobe; pronotum smooth anteriorly; scutum with sparse, small punctures; scutellum with conspicuous rugae; propodeal dorsum coarsely, largely reticulate. Metasoma (Figs 57 & 61): petiolate; T 1 longer than hind femur, shorter than T 2 ‒ T 4 combined, its sides not parallel, 2.5 × as long as wide dorsally; T 2 ‒ T 5 largely maculate, T 6 with large yellow band anteriorly. T 2 ‒ T 7 impunctate.
