Brevipalpus obovatus Donnadieu, 1875 ( Figure 6 )

Diagnosis (Female) — Prodorsum mostly smooth centrally, strongly reticulate laterally with large cells posteriorly and smaller cells anteriorly, setae short, serrate; opisthosoma between setae c1 and e1 weakly reticulate to weakly wrinkled, cuticle between and posterior to setae e1 with short transverse folds, setae f2 absent, with marginal setae short, serrate and 3 pairs of dorsocentral setae apparently smooth ( Fig 6A ); genital and ventral shields colliculate (having small elevations) ( Fig 6B ); rostrum extends to about middle of femur I; palp tarsus II with one solenidion distally; spermatheca terminates into a round vesicle with short finger-like projections around entire perimeter ( Fig 6C ).

Deutonymph — Prodorsum with setae sc1-2 short but clearly longer than v2, opisthosoma also with setae short but c1, d1, d3 and e1 shorter than c3, e3, f3, h1-2 ( Fig 6D ).

Hosts and localities — On a wide range of hosts, but mainly citrus from: Argentina, Australia, Brazil, Canada, Chile, China, Colombia, Costa Rica, Democratic Republic of Congo,
