Charipinae key

1. Metasoma with two large visible terga, subequal in length along middorsal line, but basal tergite 1/4-1/3 smaller than second in lateral view (a). Antenna with all flagellomeres separated by constrictions (d). Posterodorsal extensions of axillar strip present. Biology (for those genera where it is known) related to hyperparasitism of Aphididae. …………… 2
– Metasoma with a single tergal plate, or if two, then basal tergite much shorter than second along middorsal line (b, c). Antenna with two last flagellomeres broadly jointed or fused (e). Posterodorsal extension of axillar strip absent. Biology (for those genera where it is known) related to hyperparasitism of Psyllidae. …………………………….………….. 5

2. Lower part of mesopleuron with horizontal sulcus (f). Cosmopolitan………………. ………………………………………………………..………….. Phaenoglyphis Förster, 1869
– Mesopleuron lacks horizontal sulcus (g). ………………………….………….…………… 3

3. Forewing with an undulation present in the apical part of the posterior margin (i). Antenna with a cup-shaped pedicel. Only known from Nepal. …………………………….. …………………………………. Lobopterocharips Paretas-Martínez and Pujade-Villar, 2007
– Margin of the forewing continuous (j). Antenna with a cylindrical pedicel. ………………. 4

4. Mesopleuron lacks mesopleural triangle (h). Head and mesosoma with fine reticulate sculpturing. Nearctic. …………………………………………………. Lytoxysta Kieffer, 1909
– Mesopleuron with mesopleural triangle (Figs g). Head and mesosoma not sculptured. Cosmopolitan. ………………………………………………………… Alloxysta Förster, 1869

– Metasoma appearing unsegmented, only one tergite visible (c). R1 very short, not reaching wing margin …………………………………………………….……………………. 6

6. Apex of scutellum with a ∩-shaped projected plate (k) or with one carina on each side, both symmetrical and parallel higher than axilar strip, distance between them equivalent to distance between propodeal carinae. Female antenna with 11 flagellomeres. Cosmopolitan except Neotropics and Australia. ……………………….. Dilyta Förster, 1869
– Apex of scutellum without projected plate but with symmetrical carinae longer than axilar strip. Female antenna with less than 11 flagellomeres. ……………………………………. 7

7. Head elongated in anterior view. Female antenna with 10 flagellomeres, apical club two-segmented. Three carinae at each side of the scutellum apex (l). Radial cell large, 2r as long as Sc+R1; Rs long and curved and giving an elongated aspect to the radial cell. Only known from Australia. .……………….. Dilapothor Paretas-Martínez and Pujade-Villar, 2006
– Head rounded in anterior view. Female antenna with 9 flagellomeres (Fig. 3h), apical club not segmented. One small carina present at each side of the scutellum apex. (m). Radial cell small, 2r shorter than Sc+R1; Rs short and almost straight. Only known from Australia………………………………………..………….………….Thoreauana Girault, 1930
