KEY TO GENERA OF CHARIPINAE

The following key refers the extant genera of Charipinae . The only known fossil genus of Charipinae , Protocharips , is morphologicaly close to Alloxysta which differs in having complete notauli, forewings with a long postmarginal vein, and areola closed.

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 ( Fig. 9a). Antenna with all flagellomeres separated by constrictions ( Figs 3a, b, c, d, e, f). Posterodorsal extensions of axillar strip present ( Fig. 10a). 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 ( Figs 9b, c, d). Antenna with two last flagellomeres broadly jointed or fused ( Figs 3g, h, i, j). Posterodorsal extension of axillar strip absent ( Fig. 10b). Biology (for those genera where it is known) related to hyperparasitism of Psyllidae ....................... 5

2 Lower part of mesopleuron with horizontal sulcus ( Fig. 1b). Cosmopolitan.................. Phaenoglyphis Förster, 1869

– Mesopleuron lacks horizontal sulcus ( Figs 1b, c)............................................................. 3

3 Forewing with an undulation present in the apical part of the posterior margin ( Fig. 8b). Antenna with a cup-shaped pedicel ( Fig. 3e). Only known from Nepal......................... Lobopterocharips Paretas-Martínez and Pujade-Villar, 2007

– Margin of the forewing continuous ( Figs 8a, c). Antenna with a cylindrical pedicel.................................. 4

4 Mesopleuron lacks mesopleural triangle ( Fig. 1c). Head and mesosoma with fine reticulate sculpturing ( Fig. 1c). Nearctic..................................................................................... Lytoxysta Kieffer, 1909

– Mesopleuron with mesopleural triangle ( Figs 1a, b). Head and mesosoma not sculptured ( Fig. 1a). Cosmopolitan............................................................................................ Alloxysta Förster, 1869

5 Metasoma with a small basal tergum, terminating just posterior to ring of setae ( Fig. 9b). R1 long and reaching wing margin. Palaearctic and Neotropical........................................................ Apocharips Fergusson, 1986

– Metasoma appearing unsegmented, only one tergite visible ( Figs 9c, d). R1 very short, not reaching wing margin........ 6

6 Apex of scutellum with a ∩-shaped projected plate ( Fig. 7d) or with one carina on each side, both symmetrical and parallel higher than axilar strip, distance between them equivalent to distance between propodeal carinae ( Fig. 7e). Female antenna with 11 flagellomeres ( Fig. 3i). Cosmopolitan except Neotropics and Australia...................... Dilyta Förster, 1869

– Apex of scutellum without projected plate but with symmetrical carinae longer than axilar strip ( Figs 7g, h). Female antenna with less than 11 flagellomeres ( Figs 3h, j)................................................................. 7

7 Head elongated in anterior view. Female antenna with 10 flagellomeres ( Fig. 3j), apical club two-segmented ( Fig. 3j). Three carinae at each side of the scutellum apex ( Fig. 7g). 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 ( Fig. 3h). One small carina present at each side of the scutellum apex ( Fig. 7h). Radial cell small, 2r shorter than Sc+R1; Rs short and almost straight. Only known from Australia.................................................. Thoreauana Girault, 1930
