From: A phylogenomic study of Steganinae fruit flies (Diptera: Drosophilidae): strong gene tree heterogeneity and evidence for monophyly

Fig. 1

Distribution 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. For further information regarding the recovered topologies, see Fig. S1 (Additional file 1)
