Key to Jataiba species

Adults

1 Genal processes widely separated medially, axes subparallel; anteorbital tubercle on vertex small, nipple-like ( Fig. 72, arrow). Forewing slender, 2.6 times as long as broad ( Fig. 74). Male and female terminalia as in Figs 81, 90, 91, 98. On Hymenaea ........................................................................................... J. hymenaeae

- Genal processes narrowly separated or almost adpressed medially, axes converging towards apices; anteorbital tubercle on vertex big, flattened ( Fig. 73, arrow). Forewing broad, 2.1–2.3 times as long as broad ( Fig. 75). Terminalia different ( Figs 78–80, 82–89, 92–97, 99, 100. On Copaifera ..................................................................... 2

2 Forewing with surface spinules covering most of apical half of wing except for spinule-free stripes along the veins. Sclerotised end tube of ductus ejaculatorius small, originating at base of distal aedeagal segment ( Fig. 85). Female subgenital plate long, 0.5–0.6 times as long as proctiger; dorsal outline relatively straight ( Fig. 96). Brazil: AC, MT................ J. basifistula

- Forewing with surface spinules much reduced, present, in apical half of wing, only around radular areas. Sclerotised end tube of ductus ejaculatorius large, originating in apical half of distal aedeagal segment ( Figs 87, 89, 93, 95). Female subgenital plate short, 0.4–0.5 times as long as proctiger; dorsal outline with distinct angular lobe in apical third ( Figs 97, 99–101)........ 3

3 Male proctiger with distinct, relatively small, narrow posterior lobes basally ( Fig. 82). Aedeagus indistinctly 3-segmented; distal portion only weakly explanded apically ( Fig. 93). Female proctiger straight and truncate apically; subgenital plate with deep, transverse incision subbasally ( Fig. 99). Brazil: GO, PI............................................. J. incisa

- Male proctiger lacking narrow posterior lobes, though slightly produced basally ( Figs 79, 80, 83). Aedeagus 2-segmented; distal portion strongly explanded apically ( Figs 87, 89, 95). Female proctiger slightly upturned and pointed apically; subgenital plate without subbasal incision ( Figs 97, 100)............................................................... 4

4 Antenna> 4.8 mm. Panama.......................................................................... J. sp.

- Antenna <4.6 mm. Brazil.............................................................................. 5

5 Paramere with subparallel margins, apical sclerotised tooth at the rear corner ( Fig. 88). Sclerotised end tube of ductus ejaculatorius less than half as long as distal aedeagal segment ( Fig. 89). Female unknown. Brazil: AM................ J. cognata

- Paramere irregularly tapering to apex, apical sclerotised tooth near apex in the middle ( Figs 86, 94). Sclerotised end tube of ductus ejaculatorius more than half as long as distal aedeagal segment ( Figs 87, 95)................................. 6

6 Smaller: antenna <4.0 mm, forewing <2.5 mm. Male proctiger with slightly angular posterior bulge in basal third ( Fig. 79). Paramere relatively broad in apical third, with fewer thick setae on the inner face in apical third ( Fig. 86). Basal projection of distal portion of aedeagus small ( Fig. 87). Brazil: BA, PI.............................................. J. cearensis

- Larger: antenna> 3.8 mm, forewing> 2.4 mm. Male proctiger with broadly rounded posterior bulge in basal third ( Fig. 83). Paramere relatively slender in apical third, with more thick setae on the inner face in apical third ( Fig. 94). Basal projection of distal portion of aedeagus large ( Fig. 95). Brazil: MG, PR, SP.......................................... J. uncigera
