Fig. 1From: A phylogenomic study of Steganinae fruit flies (Diptera: Drosophilidae): strong gene tree heterogeneity and evidence for monophylyDistribution of gene trees supporting Steganinae monophyly or paraphyly. Pie chart colors relate to the color of the gene tree topologies. Of the 1,028 gene trees analyzed, 46.7% recovered the Steganinae subfamily as monophyletic and 53.4% recovered it as paraphyletic. Among the monophyletic-Steganinae trees, the predominant topology (a, in blue) grouped Rhinoleucophenga cf. bivisualis as the sister group of Phortica variegata + Cacoxenus indagator with a frequency of 43.7% of the total gene trees. Among the paraphyletic-Steganinae trees, two topologies were recovered with higher frequency, accounting, respectively, for 32.8% (b) and 13% (c) of the total gene trees. All the other possible topologies occurred at low frequencies, accounting together for 10.5% of the total gene trees.
