description: Anagyrus fusciventris (Girault)   
Figs. 6–8.  
 Epidinocarsis fusciventris Girault, 1915: 144. Holotype female, Australia.   
 Anagyrus nigricornis Timberlake, 1919: 199. Holotype female, Hawaii.   
 For a detailed description, see Timberlake (1919: 197, as A. nigricornis).   
 Diagnosis. Female. Body length: 1200-1800. Body (Fig. 6) color non-metallic, generally orange, except as follows: dark brown spot from postgena until mouth margin; frontovertex yellowish, lighter than rest of the thorax; eyes distinctly black, densely setose; scape with characteristic white spot, rest of antenna dark brown (Fig. 7); collar of pronotum white, with a row of long black setae, sometimes interrupted by white setae; metasoma brown; tegula white. Forewing hyaline but apical area with distinctly paler setae (Fig. 8); postmarginal vein a little longer than stigmal and 2.5x as long as wide; linea calva interrupted by four or five setae lines dorsally and four ventrally (Fig. 8). Legs yellowish white, except coxae, apex of tibiae and tarsi yellow. Female antenna length/width proportions: scape: 2.2x, pedicel: 3.6x, F1: 3.5x, F2: 2.8x, F3: 2.3x, F4: 2.0x, F5: 1.4x, F6: 1.2x, clava: 2.8x. F1–F6 decreasing in length and increasing in width. Ovipositor not exserted. Male antenna (Fig. 9) with a line of 5–6 (usually 5) scalelike sensilla present only on base of the clava (Fig. 10).

 Host. Anagyrus fusciventris is a parasitoid of pseudococcids and, among them, it is associated to the obscure mealybug Pseudococcus viburni although this relationship seems to be established in laboratory rearing experiments (Blumberg & Driesche 2001; Noyes 2018). We have been able to observe A. fusciventris emerging from young P. viburni females collected on persimmon crops (Diospyros kaki L.f.) and kept in controlled insectariums, and also as a parasitoid of P. longispinus on persimmon and Japanese sago palm (Cycas revoluta Thunb.). We considered that a confirmation of the association of this parasitoid with P. viburni under natural field conditions in Spain.   
 Comments. Anagyrus fusciventris is a species originally found in Australia but widely distributed around the world; in Europe is only cited from Italy, where it is attacking Pseudococcus calceolariae (Maskell) on citrus crops (Viggiani & Battaglia 1983). This is a new record from Spain. The specimens were identified by comparison with literature descriptions.
