|---|---|---|---|
| 1-1 |
H8 (I) H9 (T) I-T |
Dc> ; Dn> Dc> ; Dn> |

Phylogeographic inferences are inferred by applying the inference key of Posada et al. (2000) (http://darwin.uvigo.es/software/geodis.html)
(T): tip; (I): interior; Dc: clade distance; Dn: nested clade distance; I-T: interior vs. tip clades
