Fore wing with dark band behind marginal vein that is proximally and distally diffusely delimited ( Fig. 7E ), discal seta present. Mt8 in female transverse, without a medial incision.

Morphology. Head 1.76 times as broad as frontovertex width ( Fig. 7B ), frontovertex width 0.77 times length of clava, distance from mouth margin to facial ridge 0.57 times head height. Antenna with 3 anelli ( Fig. 4D ), F1 0.4 times as long as broad, F2 0.8 times as long as broad, F3 subquadrate, clava about 6 times as long as broad and 1.7 times as long as scape length ( Fig. 7D ), pedicel 0.77 times as long as scape length. Midlobe of mesoscutum with 2 setae on disc and anteriorly with 6 setae, scutellum with 6 setae along posterior margin. Fore wing 2.9 times as long as broad ( Fig. 4E ), longest setae of marginal fringe 1.4 times as long as width of disc, seta M1 present, M2b absent. Midtibial spur subequal in length to corresponding basitarsus ( Fig. 4C ), the latter 0.56 times as long as midtibia. Ovipositor 2.1 times as long as midtibia and 1.4 times as long as hind tibia.

Host.

Diaspididae ( Hemiptera , Sternorrhyncha).

Distribution.

Widely distributed in the tropics and, apart from Indonesia, recorded from the following countries (after Woolley and Dal Molin 2017): Argentina, Cuba, Brazil, Chile, Egypt, French Polynesia, Haiti, India, Mexico, Panama, Papua New Guinea, Peru, Trinidad and Tobago, South Africa, Taiwan, Thailand, USA.

DNA barcode data.

The sequence of the single examined specimen is separated by 9.7% from the nearest neighbour species, S. flavella (Suppl. material 1, Genbank Accession Number: MH407234).

Remarks.

The species belongs to the Signiphora flavopalliata species group and can be separated from other species in the group, among other characters, by its light colour (female) and the presence of a discal seta in the fore wing (fig. 306 in Woolley and Dal Molin 2017).
