Key to Florida species of Bactericera

(Characters to separate B. arcuata and B. schwarzii are taken from Tuthill (1942); see also comments under B. arcuata and B. schwarzii )

1. Genal processes well-developed, about as long as vertex along mid-line ( Fig. 153 ). On Salix caroliniana Michx. (Salicaceae) . Habitus in Fig. 151.............................. B . nigrilla (Crawford)

— Genal processes absent or very short, pad-like. On other hosts................................. 2

2(1). Head, in dorsal view, not cleft anteriorly. Color of antennal segments: 3 light; 4‒8 light at base, dark at apex; 9 and 10 dark brown to black. Habitus in Fig. 149.................................... 3

— Head, in dorsal view, cleft anteriorly. Color of antennal segments: 3 brown basally, light otherwise; 4, 5 light; 6‒10 dark brown to black......................................................... 4

3(2). Vein Rs of forewing long: bifurcation of vein M proximal to line joining apices of veins Rs and Cu 1a. Polyphagous, particularly on Solanaceae ................................ * B. cockerelli (Šulc)

— Vein Rs of forewing short: bifurcation of vein M distal to line joining apices of veins Rs and Cu 1a ( Fig. 149 ). On Lycium spp................................................ B. dorsalis (Crawford)

4(2). Head with eyes lateral rather than anterior. Profemora weakly inflated. Vein Rs of forewing shorter and more strongly arched................................................. B. arcuata (Tuthill)
