Signiphora bennetti Woolley & Dal Molin Fig. 5 A–F View Figure 5

Signiphora bennetti Woolley & Dal Molin, 2017: 19-23.

Material examined.

Indonesia • 4 ♀ (on slide); West Java, Mount Halimun-Salak National Park, waterfall; 6.71250S, 106.52305E; 1100 m a.s.l.; 18-Sept-2015; A. Polaszek leg.; Yellow Pan trap; MZB DNA 1321; ZSM DNA 1318; NHMUK DNA 1319-20.

Diagnosis (female).

Female with pale band from distal mesoscutum to the proximal propodeal triangle. Antenna with 3 anelli ( Fig. 5E View Figure 5 ). Marginal vein dorsally with 3 setae, seta M1 missing ( Fig. 5C View Figure 5 ), usually with minute seta distal to M2.

Description (female). Colour. Head and body dark brown ( Fig. 5A, B View Figure 5 ), with distal half of mesoscutum, scutellum, metanotum and anterior part of propodeal triangle distinctly pale in contrast; legs pale with hind femora brown ( Fig. 5A View Figure 5 ), antenna yellow-brown with clava darker, increasingly so distally ( Fig. 5E View Figure 5 ). Fore wing with brown infuscation centrally and on marginal vein ( Fig. 5C View Figure 5 ).

Morphology. Head 1.5 times as broad as frontovertex width ( Fig. 5B View Figure 5 ), frontovertex width 1.04 times length of clava. Antenna with 6 antennomeres and with 3 anelli, clava 4.6 times as long as broad and 1.7 times as long as scape length, pedicel 0.6 times as long as scape length ( Fig. 5E View Figure 5 ). Midlobe of mesoscutum with 2 fine setae in posterior half, scutellum with 4 fine setae along posterior margin. Fore wing 3.5 times as long as broad ( Fig. 5C View Figure 5 ), longest setae of marginal fringe 1.52 times as long as width of disc, marginal vein seta M1 absent, M5 absent in some paratypes; stigmal seta long ( Fig. 5C View Figure 5 ), vestigial seta base/socket present between M5 and M6 on lower edge of marginal vein, discal seta absent ( Fig. 5C View Figure 5 ). Midtibial spur 0.84 times as long as corresponding basitarsus ( Fig. 5F View Figure 5 ), the latter 0.46 times as long as midtibia. Ovipositor 1.8 times as long as midtibia and 1.4 times as long as hind tibia.


A primary parasitoid, commonly associated with Melanaspis smilacis (Comstock) ( Hemiptera , Diaspididae ) in the New World, a species also widely distributed in SE Asia. Also recorded from Hemiberlesia oxycoccus (Woglum); Melanaspis obscura (Comstock); Pseudaulacaspis pentagona Targioni Tozzetti; Comstockaspis perniciosa (Comstock) and Aspidiella sacchari (Comstock) ( Woolley and Dal Molin 2017).


Very widespread in the New World ( Woolley and Dal Molin 2017).

DNA barcode data.

The species exhibits an intraspecific variation of 0.2% and a distance of 12.5% to the nearest neighbour species, S. flavella (Suppl. material 1, Genbank Accession Numbers: MN520843, MN520844).


The species belongs to the Signiphora flavopalliata Ashmead species group and can be separated from other species in the group by the central dorsal pale band extending from the distal mesoscutum to the proximal propodeal triangle (female), absence of M1 from the marginal vein, and the presence of a minute anterior seta on the marginal vein distal to M2 (fig. 38 in Woolley and Dal Molin 2017), though this seta is not present in every specimen.
