Description of holotype.

Body length: 2.8 mm. Fore wing length: 2.7 mm.

Head. Antenna with 25 segments, whitish setose, length of third segment equal to fourth, length of third, fourth and penultimate segments 2.0, 2.0 and 1.2 times their width, respectively. Maxillary palp with 5 segments and its length 0.7 times height of head. Length of eye in dorsal view 2.2 times temple. OOL: diameter of ocellus: POL = 25:10:20. Head completely smooth with long whitish setae on lateral parts of face; length of malar space 1.5 times basal width of mandible.

Mesosoma. Length of mesosoma 2.0 times its height. Propleuron sparsely punctate. Pronotum smooth. Mesopleuron smooth, with precoxal sulcus smooth. Mesonotum smooth, with notauli crenulate anteriorly and smooth posteriorly, joining at apical third. Scutellum smooth. Propodeum rugose medially, apically faintly rugulose and with median longitudinal carina.

Fore wing. Hyaline, length of pterostigma: R1 = 40:70, 1-CU1:2-CU1 = 2:13.

Hind wing. Hyaline.

Legs. All legs smooth, length of femur, tibia and basitarsus of hind leg 5.0, 10.0, 6.0 times their width, respectively. Length of hind spur 0.25 times hind basitarsus. Tarsal claws with a basal lobe.

Metasoma. T1 striate, remainder of metasoma smooth. T1 length 1.1 times its apical width. Length of ovipositor sheath about 2.0 times hind tibia.

Colour. Black, except antenna dark brown; mandible, maxillary and labial palpi yellowish. Fore and mid legs yellowish with coxae and telotarsi brown. Hind leg dark brown. Metasoma ventrally yellowish, ovipositor sheath dark brown.

This species differs from the two previously described species by the presence of notauli on the mesoscutum and the mid and hind tarsal claws with basal lobes.

Etymology.

This species is named after the presence of tarsal lobes
