Zaglyptus guptai   sp. nov.

( Fig. 2 View FIGURE 2 )

Diagnosis. Face black, quadrate, with minute and shallow punctures; submetapleural carina nearly complete; swellings on second tergite densely coarsely punctate; swellings on tergites 3–6 polished, nearly impunctate; ovipositor straight, 2.0x hind tibia.

Description (Holotype) ( Fig. 3 View FIGURE 3 ). Body length 5.6 mm, fore wing 4.5 mm, ovipositor 2.7 mm. Head. Antenna with 23 flagellomeres, first flagellomere 1.45 x length of second; diameter of lateral ocellus equal to ocellar-ocular distance; frons pubescent; inner margins of eyes weakly concave above antennal sockets, parallel ventrally; face quadrate, pubescent, upper margin slightly concave between antennal sockets; clypeus about 0.55 x as high as wide; malar space about 0.3 x basal width of mandible; occipital carina meeting hypostomal carina at about basal mandible width from base of mandible.

Mesosoma   . Epomia as long as mandible width; pronotum impunctate and polished; mesoscutum 1.3 x as long as wide at anterior level of tegulae, pubescent, notauli indicated anteriorly, not convergent posteriorly; scutellum strongly convex, pubescent, lateral carina present basally; mesopleuron pubescent, epicnemial carina present on lower 0.7 of mesopleuron, lateral section of postpectal carina present as short stub in front of mid coxa; metapleuron polished, submetapleural carina nearly complete, posterior end indistinct; propodeum pubescent, without carinae, with mediobasal hollow; propodeal spiracle round, touching pleural carina. Fore femur 4.1 x as long as wide; hind leg with femur 4.5 x as long as wide, length 0.8 x tibia, tibia 8.0x as long as apical width; basitarsus 0.45 x length of tibia, 0.45 x tarsus, 2.8 x second tarsomere, fifth tarsomere 1.8 x third, hind tibia slightly swollen subbasally. Fore wing with vein Rs & M opposite cu-a, 2 rs-m about 0.7 x distance between 2 rs-m and 2 mcu, vein cu-a inclivous, vein Cu 1 a separated from 1 m-cu by 0.9 x length of vein Cu 1 b; hind wing with vein M+Cu moderately bowed posteriorly, first abscissa of vein Cu 1 about 0.85 x length of vein cu-a; distal abscissa of vein Cu 1 present.

Metasoma. Tergites densely, coarsely punctate, except transverse smooth bands apically; first tergite slightly shorter than its apical width, dorsolateral carina present from base to spiracle, median longitudinal carina present basally; second tergite 0.9 x length of first tergite, 0.65 x as long as apical width, basal and apical oblique grooves moderately deep, rhombic area convex, lateral swellings densely coarsely punctate; third tergite slightly shorter than second; swellings on tergites 3–6 polished, almost impunctate; ovipositor straight, cylindrical, 2.0x as long as hind tibia.

Colour. Antenna brown, scape, pedicel and first two flagellomeres yellow ventrally; frons and hind side of head black, face black except two yellow spots in front of antennal sockets; clypeus reddish brown; palpi and tegula yellow; pronotum black; mesoscutum reddish brown; scutellum and metascutellum yellow; mesopleuron reddish brown, except transverse black stripe below subalar prominence; metapleuron reddish brown, black ventrally; propodeum reddish brown, apically black; subbasal and apical bands of mid tibia and apical band of mid basitarsus brown; hind leg with basal band of femur, subbasal and apical bands of tibia and apical band of basitarsus black; wing hyaline, pterostigma and veins light brown, except coxa yellow; tergites 1, 6, 7, 8 entirely black, tergite 2 yellowish brown, except median rhombic convex area and apical transverse smooth band blackish; tergites 3–5 yellowish brown, except two lateral swellings and apical transverse smooth bands dark brown; ovipositor reddish brown.

Male. Unknown.

Distribution. Currently known only from Chu Yang Sin NP, Dak Lak Province, Central Highlands of Vietnam ( Fig. 4 View FIGURE 4 ).

Ecological note. The single specimen was collected in secondary rainforest, between 740–900 m a.s.l.

Etymology. We name this species is named after Dr Virendra K. Gupta, in honour of his great work on the taxonomy of Zaglyptus   .

Comparision. The colour pattern of the new species resembles that of Z. miarus Gupta. It   differs from Z. miarus   by the densely puntate lateral swellings on the second tergite. Moreover, the new species has a nearly complete submetapleural carina (versus present on anterior 0.4 in Z. miarus   ) and shorter ovipositor (2.0x as long as hind tibia versus 2.5 x).

Material examined. Holotype: ♀ ( RMNH), Dak Lak, Chu Yang Sin NP, Krong K’Mar, 740–900 m a.s.l, 02– 2007, Malaise trap, C. v. Achterberg & R. de Vries leg.
