( Figure 6 View Figure 6 )
Material examined
Holotype (♀). Dong Nai, Cat Tien NP, 100 m, 13–19 May 2007, Malaise trap, C.v. Archterberg and R. de Vries leg. ( RMNH).
Paratype: 1♀ same data as holotype except 13–20 May 2005 ( IEBR) .
Diagnosis
Scutellum conical with a curved carina pointing posteriorly at summit; ovipositor slightly down-curved, 1.2 × as long as hind tibia.
Description of holotype
Body length 8.2 mm, fore wing 7.5 mm, ovipositor sheath 1.6 mm. Head. Antenna with 29 flagellomeres, first flagellomere 1.5 × length of second; diameter of lateral ocellus slightly shorter than ocellar–ocular distance; frons polished, impunctate, with small median swelling in front of median ocellus; inner margins of eyes strongly concave opposite antennal sockets, convergent ventrally; face as high as wide, with shallow, small punctures, pubescent, upper half with median vertical ridge; clypeus flat, 0.45 × as high as wide, basally pubescent, apical margin thin, emarginate; mandible with lower tooth 1.5 × as long as upper tooth; malar space short, about 0.15 × basal width of mandible; occipital carina complete, meeting hypostomal carina at about 0.7 × basal mandible width.
Mesosoma
Pronotum polished, pubescent along upper margin; epomia absent; mesoscutum 1.1 × as long as wide at anterior level of tegulae, with dense, short hairs; notaulus impressed, extending to level of middle of tegula; scutellum pyramidal, posterior impunctate area without small striations, lateral carina extending to middle, at summit with transverse carina curving posteriorly; mesopleuron with dense, short hairs, outer margin of subalar prominence moderately sharp, epicnemial carina present on lower half; metapleuron with dense, short hairs; propodeum pubescent basally, area superomedia open posteriorly, basal transverse carina entirely absent, lateral longitudinal carina interrupted below posterior transverse carina; pleural area with dense, long hairs, pleural part of posterior transverse carina partly present, propodeal spiracle elongate, 3.0 × as long as wide. Hind femur 3.3 × as long as wide, length 0.85 × hind tibia, tibia 5.7 × as long as apical width, basitarsus 0.35 × length of tibia, 0.37 × tarsus, 1.9 × second tarsomere, fifth tarsomere 2.0 × length of third. Fore wing with vein Rs & M basad of cu-a, vein 2 rs-m about 0.6 × vein 3 rs-m, vein Cu 1 a separated from 1 m-cu by 1.3 × length of Cu 1 b; hind wing with distal part of vein M + Cu straight, first abscissa of vein Cu 1 0.37 × as long as vein cu-a.
Metasoma
Tergites with dense, short hairs; first tergite elongate, 2.2 × as long as apical width, lateral carina present basally; second tergite 0.6 × as long as apical width, 0.6 × length of first tergite, basal and apical oblique grooves moderately deep; third tergite shorter than second; median areas of tergites 2–3 divided into two lateral swellings; first sternite smooth, extending to level of spiracle; ovipositor slightly down-curved, length from tip of hypopygium 1.2 × hind tibia length, ovipositor tip depressed, tapered to sharp point, lower valve apically with eight curved ridges.
Colour
Pale yellow, black in following areas: ocellar area, hind side of vertex, hind corner of pronotum, three stripes on mesoscutum merging posteriorly with black mark in front of scutellum, median stripe narrower apically, apical part of scutellum, basal part of propodeum dorsally and laterally, mid tibia, hind tarsus. Mesopleuron with dark brown stripe below subalar prominence and a brown oblique band extending from posterior margin at the level of episternal scrobe to epicnemial carina, mesepisternum and metaepisternum widely brown; posterior face of fore femur marked with light brown; mid leg with inner face of coxa, posterior and ventral faces of tibia marked with light brown; hind leg with outer face of coxa, trochanter, trochantellus dark brown, lateral and ventral faces of femur brown; wings hyaline, pterostigma and veins brown; metasomal tergites with brown basal bands broader than yellow apical bands; ovipositor reddish brown; ovipositor sheath black and hairy.
Male. Unknown
Variation
The paratype agrees well with the holotype.
Comparison
In general appearance, this species resembles Nomosphecia insolens ambona (Gupta) except for its longer (1.2 × hind tibia versus 0.8 ×) and down-curved ovipositor and the curved carina at the summit of the scutellum.
Etymology
This new species is named after the curved carina at the summit of the scutellum.
Distribution
Currently known only from Cat Tien NP, Dong Nai Province (South Vietnam) ( Figure 5 View Figure 5 ).
Ecological note
The specimens were collected in lowland evergreen forest at an elevation of 100 m a.s.l.
