Key to Neotropical psyllid genera associated with Detarieae

Adults

1 Head lacking genal processes ( Figs 1, 2 ). On Hymenaea ............................................ Platycorypha

- Head bearing genal processes ( Figs 3–6 )................................................................... 2

2 Metatibia lacking genual spine. Forewing rhomboidal or subrectangular; dark brown to almost black ( Fig. 7 ). Vertex subrectangular, with base straight, completely flattened dorsally including area adjacent to median ocellus; separated from genae by transverse suture; genal processes with dorsal surface lying in the same plane as vertex, flattened dorsally, usually irregularly truncate apically ( Fig. 3 ). On Copaifera .......................................................... Colophorina

- Metatibia with conspicuous genual spine. Forewing ovoid to oblong oval, broadly, sometimes irregularly rounded apically; light, sometimes with dark pattern ( Figs 8–10 ). Vertex trapezoidal, with base weakly concave, dorsally with raised lateral ocelli and anteorbital tubercle as well as area adjacent to median ocellus, coronal suture incised; separated from genae by deep transverse incision; genal processes with dorsal surface lying in a different plane to that of vertex, sometimes inclined, convex dorsally, conical, pointed or blunt apically ( Figs 4–6 )......................................................... 3

3 Forewing long and narrow,> 2.7 times as long as wide ( Fig. 8 ). Dorsal surface of genal processes, in lateral view, at an angle of 80° to that of vertex. Metatibia with 4–5 regularly spaced apical spurs. On Hymenaea ..................... Apsyllopsis

- Forewing shorter and wider, <2.7 times as long as wide ( Figs 9, 10 ). Dorsal surface of genal processes, in lateral view, more or less parallel to that of vertex. Metatibia with 1+3+1 apical spurs................................................ 4

4 Vertex flat on either side of coronal suture; genal processes evenly tapering, pointed, ≥ 0.7 times as long as vertex along midline ( Fig. 5 ). Antennae> 2.7 mm,> 3.4 times as long as head width........................................ Jataiba

- Vertex with prominent ridge on either side of coronal suture; genal processes blunt or subacute, or <0.8 times as long as vertex along mid-line ( Fig. 6 ). Antennae <3.0 mm, <3.4 times as long as head width............................. Mitrapsylla

Last instar immatures

1 Abdomen, apart from circumanal ring, bearing additional pore fields ( Figs 11, 12 ). Living in leaf roll galls.............. 2

- Abdomen lacking additional pore fields ( Figs 13–15 ). Free living............................................... 3

2 Antenna long, about 1.5 times as long as forewing pad. Forewing pad long and narrow,> 3.5 times as long as wide; hindwing pad lacking sectaseta ( Fig. 16 ). Tarsal arolium small, shorter than claws ( Fig. 18 ). Abdomen with 5+5 marginal sectasetae. On Hymenaea .................................................................................. Apsyllopsis

- Antenna short, about as long as forewing pad or shorter. Forewing pad short and broad, <3.0 times as long as wide; hindwing pad bearing one marginal sectaseta ( Fig. 17 ). Tarsal arolium large, longer than claws ( Fig. 19 ). Abdomen with 4+4 marginal or submarginal sectasetae. On Copaifera ........................................................... Colophorina

3 Wing pads and caudal plate conspicuously dark along margin, abdomen flat; anus ventral ( Fig. 15 ). Hindwing pad with one marginal sectaseta. On Hymenaea .............................................................. Platycorypha

- Wing pads and caudal plate lacking dark margin, abdomen inflated, weakly sclerotised; anus terminal ( Figs 13, 14 ). Hindwing pad lacking sectaseta.................................................................................. 4

4 Circumanal ring relatively small; distance from anus to outer circumanal ring about 2.0 times or less than that from there to group of sectasetae ( Fig. 13 ). Pores of circumanal ring very narrow and long ( Fig. 20 ).......................... Jataiba

- Circumanal ring relatively large; distance from anus to outer circumanal ring longer than 2.0 times distance from there to group of sectasetae ( Fig. 14 ). Pores of circumanal ring oval, about twice as long as wide ( Fig. 21 ).................. Mitrapsylla
