1	Forewing with vein R+M+Cu1 bi-furcating to form R and M+Cu1 (Figures 23, 25, 28)	2
–	Forewing with vein R+M+Cu1 tri-furcating to form R, M and Cu1 (Figures 24, 29)	4
2	Forewing with veins R and M+Cu1 equally long or M+Cu1 slightly longer than R (Figures 7, 23). Body colour black with orange stripes on the dorsum	Syntomozatahuata (Klyver, 1932)
–	Forewing with vein R longer than M+Cu1 (Figures 25, 28). Body colour light green	3
3	Forewing with vein Rs very short (♂ 0.91, ♀ 1.14), strongly bent towards margin at apex, with a transverse vein crossing from centre of Rs to the bi-furcation between M1+2 and M3+4 (Figure 28)	Mesohomotomahibisci (Froggatt, 1901)
–	Forewing with vein Rs not turning upward and no transverse vein crossing the wing (Figure 25)	Heteropsyllacubana Crawford, 1914
4	Forewing with vein Cu1 not bi-furcating and therefore not forming cell cu1 (Figure 22). Body colour light brown	Leptynopterasulfurea Crawford, 1919
–	Cell cu1 present (Figures 24, 29). Body colour darker brown/black	5
5	Forewing with dark spot on cell c+sc (Figures 17, 26). Body colour black with subtle brown patterning	Triozaalifumosa Klyver, 1932
–	Forewing with no spots (Figures 24, 29). Body colour brown with tan pattern or black with pale stripe on the abdomen	6
6	Male genitalia with parameres pointing forward at apex and proctiger bearing long setae on the apical part facing the parameres. Female genitalia extremely short, approximately ¼ of abdomen. Length of psyllid to tip of folded wings between 5 mm and 6 mm. Body colour brown, with tan patterning	Triozavitiensis Kirkaldy, 1907
–	Male parameres pointing backward at apex, proctiger bearing short setae uniformly, female terminalia longer (half of the rest of abdomen). Length of the psyllid to tip of folded wings only 3.5mm. Body colour black with pale stripe at base of abdomen	Triozacf.zimmermani Tuthill, 1942
