Figure 3.
Parsimonious phylogeny of world fishfly genera.
Bootstrap values/Bremer’s decay indices are indicated at each node, unambiguous apomorphies were mapped. Black circle represents non-homoplastic change, white circle represents homoplastic change, characters states for multistate characters and reversals are placed above corresponding circles. Habitus photos of representative genera of all lineages shown at right.

Ancestral distribution reconstruction of fishflies under DIVA analysis along one of the most parsimonious trees.
A, Cladogram with geologic periods calibrated to a time scale in millions of years at left. Fossil localities of fishflies marked at far left. Circles indicate the fossil records. Color of branches corresponds to the distributed areas of fishfly genera shown in Fig. 4B, branches with mixed color indicate disjunctive distribution among different areas. B, Distribution map of world fishflies, circles indicate the localities of fossil fishflies. Areas are coded as follows: a, Asia; b, eastern Australia; c, western Australia, d, southern African continent; e, Madagascar; f, eastern North America; g, western North America; h, southern South America; i, Europe.
