Figure 1 in Systematics and phylogeny of the tribe Paragini (Diptera: Syrphidae) based on molecular and morphological characters

Figure 1. One of the six most parsimonious trees using only morphological characters. Multistate characters treated as unordered (length = 53 steps, consistency index = 0.69, retention index = 0.92). Character numbers are indicated above nodes, character states below nodes. Closed circle, non-homoplastic changes; open circle, changes with homoplasy. The current taxonomy [Stuckenberg's (1954a, b) species groups] is shown on the right side of the tree. B = bicolor-group; T = tibialis-group.
