Acropimpla mucronis sp. nov.
Diagnosis. Face yellow with small triangular black mark centrally connecting with black clypeus, yellow inner orbits extending beyond antennal sockets; propodeum with median longitudinal carinae distinct; scutellum and metascutellum yellow; metasomal tergites reddish with first tergite basally and second and third tergites narrowly apically black; ovipositor 3.10x as long as hind tibia.
Description (Holotype) ( Fig. 5 View FIGURE 5 ). Body length 12.0 mm, fore wing 10.30 mm, ovipositor 9.20 mm. Head. Antenna with 23 flagellomeres, first flagellomere 1.33x length of second; diameter of lateral ocellus 0.82x ocellarocular distance; frons subpolished; face 0.67x as high as wide, slightly convex medially, with shallow and moderate-sized punctures, pubescent, upper margin of face nearly straight, with very broad concavity; clypeus with median apical notch, basally moderately convex, apex thin and emarginate; malar space about 0.33x basal width of mandible; upper tooth of mandible slightly longer than lower tooth; occipital carina complete, meeting hypostomal carina above base of mandible.
Mesosoma. Epomia present, about 0.60x basal width of mandible; pronotum polished; mesoscutum with dense, minute hairs, notauli shallowly present on anterior 0.25 of mesoscutum, nearly extending to line connecting front edges of tegulae; scutellum weakly convex, with moderately dense punctures, apically smooth, without striations, lateral carinae absent; metascutellum polished; mesopleuron subpolished, anterior half with moderately small punctures, pubescent, posterior half smooth and shiny, epicnemial carina strong and reaching anterior margin of mesopleuron, lateral sections of postpectal carina present to middle of mid coxa; metapleuron with lower half polished, upper half with some small punctures, pubescent, pleural carina complete; propodeum strongly convex, declivous, lateral and pleural areas of propodeum with dense, rugose punctures, pubescent, median longitudinal carinae present on basal 0.67, diverging; propodeal spiracle round. Hind leg with femur 4.0x as long as wide, 0.76x length of tibia, basitarsus 0.40x length of tibia, 0.53x tarsus, 3.0x length of second tarsomere. Fore wing vein 2 rs-m 0.50x length of 3 rs -m; cu-a opposite Rs+M; cell 1+2Rs trapezoidal, vein 2 m-cu slightly basad of 3 rs-m; hind wing with first abscissa of vein Cu 1 about 2.30x length of vein cu-a; vein Cu 1 present.
Metasoma. Tergites densely punctate except apical transverse, smooth bands and concave area at base of first tergite; first tergite 0.76x as long as apical width, dorsolateral carina present on apical 0.50, dorsal median carina extending to declivity; second tergite 0.60x apical width; 1.10x third tergite; ovipositor straight, 3.10x length of hind tibia, cylindrical, with oblique ridges at tip of lower valves.
Colour. Antenna blackish, except lower side of scape and pedicel yellow; face yellow except small, blackish triangular area connecting with clypeus, yellow inner orbits extending beyond antennal sockets; clypeus black; head and mesosoma black except upper margin of pronotum, subtegular ridge, scutellum, metascutellum, fore and mid leg yellow; hind leg reddish; wings hyaline, pterostigma and veins black, except basal 0.70 of costa yellowish; metasomal tergites reddish except concave area at base of first tergite and transverse smooth bands at apex of second and third tergites black; metasomal sternites whitish with two blackish spots laterally on sternites 2–6,gites black; spots on sixth sternite largest, nearly touching each other; ovipositor reddish, ovipositor sheath black and hairy.
Distribution. Currently known only from Cat Tien NP, Dong Nai Povince, southern Vietnam ( Fig. 7 View FIGURE 7 )
Ecological note. The single specimen was collected in secondary evergreen forest in a lowland area.
Similar species. The triangular, black mark on the face connecting with the black clypeus is most similar to A. punctata Baltazar ( Gupta & Tikar 1976; Liu et al. 2010). However, the new species can be distinguished from the latter by the more extensive yellow inner orbits, extending beyond the antennal sockets, and by the rest of the head and most of the mesosoma being black. In addition, this species lacks a rugose area between the median longitudinal carinae apically.
Etymology. The name mucronis is derived from the Latin for sword point, after the prominent black point on the face.
