Figures 23 , 26 Etymology. This is a very smooth and shining species with weak and sparse punctuation; it obtained its name due to its sparkling appearance. Description. Known from female holotype only. Fore wing length 5.8 mm . Antenna with 37 flagellomeres. Mesoscutum with only a few weak punctures along front margin and sometimes along notauli. Scutellum without punctures, all smooth and shining. Mesopleuron with only few, weak punctures, mostly smooth and shining; below subtegular ridge smooth and without punctures. Metapleuron with juxacoxal carina absent or at most a short basal carina. Propodeal areas and hind coxa smooth with very few very weak punctures. Hind femur length to width ratio 3.7, ventrally with a large tooth that is longer than width of hind tibia at mid length, and adjacent smaller teeth. Hind tibia 2.1 mm . Second tergite 2.1 × longer than wide at base, smooth and shining. Ovipositor 2.2 × as long as hind tibia. Colouration. Antenna orange on scape and pedicel, remainder uniformly black. Head entirely orange. Mesosoma including propodeum orange. Hind femur orange, with apex yellow. Hind tibia orange-brown with base and apex broadly darkened. Fore wing strongly infuscate, smoky-brown. Tergite 1 orange at base, black on remainder, tergite 2 black, tergites 3 onwards black or dark brown with wide, light apical bands that are often laterally interrupted by dark round mark. Notes. This species is very close to P. bicinctus , but can be clearly distinguished by the much weaker punctuation on the mesosoma. Material examined.
