description: Key to the families and subfamilies of adult Psylloidea of Israel
1 Antennal flagellar segments thick, flattened laterally and densely covered in conspicuous black setae. Male proctiger distinctly 2-segmented. On Ficus (Moraceae) .............................................. Homotomidae: Homotoma ficus
- Antennal flagellar segments slender, rounded in cross-section, not covered in long black setae. Male proctiger usually 1-segmented.............................................................................................. 2
2 Forewing with vein R+M+Cu trifurcating or, rarely, bifurcating; costal break and pterostigma absent; anal break in distance of apex of vein Cu1b. Metabasitarsus without black lateral spurs............................................ Triozidae
- Forewing with vein R+M+Cu bifurcating into R and M+Cu; costal break and pterostigma present or absent; anal break close to apex of vein Cu1b. Metabasitarsus with 0, 1 or 2 black lateral spurs............................................... 3
3 Metacoxa lacking meracanthus, but bearing a weakly sclerotised tubercle at trochanteral cavity.......... Aphalaridae p.p. 4
- Metacoxa with distinct horn-shaped meracanthus............................................................ 5
4 Metacoxa slender, with weakly curved hind margin...................................... Aphalaridae: Rhinocolinae
- Metacoxa thick, with angular hind margin. On Eucalyptus (Myrtaceae) .................. Aphalaridae: Spondyliaspidinae
5 Head with distinct, though sometimes small, genal processes. Basal spine of metatibia often developed; apical metatibial spurs always grouped.................................................................................. Psyllidae
- Head usually with rounded genae not forming genal processes but sometimes with anterior lobes; if genal processes developed metatibia with an open crown of densely spaced apical metatibial spurs. Basal spine of metatibia always absent; apical metatibial spurs usually spaced in equal intervals, forming open crown, if grouped then vertex flattened and rectangular with anterior lobes, or evenly passing into genae........................................................................ 6
6 Metabasitarsus without black spurs.......................................................... Liviidae: Liviinae
- Metabasitarsus with 2 black spurs......................................................................... 7
7 Head with rounded genae, lacking genal processes or lobes enclosing anterior ocellus. Apical metatibial spurs forming open crown; if grouped, metatibia more than twice as long as both metatarsal segments together....... Aphalaridae: Aphalarinae
- Head bearing genal processes or anterior lobes enclosing anterior ocellus which is, therefore, only visible from above. If head without genal processes then apical metatibial spurs grouped and metatibia less than twice as long as both metatarsal segments together........................................................................... Liviidae: Euphyllurinae
