FIGURE 35. A in Systematics, biogeography and host-plant relationships of the Neotropical jumping plant-louse genus Russelliana (Hemiptera: Psylloidea)

FIGURE 35. A cladogram of Russelliana spp. based on the data matrix in Table 4, with distribution (Arw = Western Argentina, Are = Eastern Argentina, Bo = Bolivia, Br = Brazil, Cnf = Far Northern Chile (I, II Regions), Cn = Northern Chile (III, IV Regions), Cc = Central Chile (V, Metropolitana, VI Regions), Cs = Southern Chile (VII–X Regions), Csf = Far Southern Chile (XI, XII Regions), P = Peru, U = Uruguay) and available host family information (Ast = Asteraceae, Fab = Fabaceae, Ros = Rosaceae, Sol = Solanaceae, Ver = Verbenaceae). Species clades with missing host/immature data are marked with an asterisk (*). For more information on hosts and distribution see Table 5. Some species clades are numbered from 1 to 18 (see Results and Discussion). Character numbers above the branches and character states are listed in Table 3; full circles indicate uniquely derived character states (synapomorphies/autapomorphies), empty circles correspond to homoplasies
