  1. Ne-PLSC, Ne-P. brachytyla s.s, Ne-P. wilsonii, Ne-ghost indicate the effective population sizes of the reduced P. likiangensis species complex (PLSC), P. brachytyla s.s., P. wilsonii, the ghost intermediate lineage and ancestral population respectively. m1PLSC->P. wilsonii, m1P. wilsonii->PLSC, m2PLSC->P. wilsonii, m2P. wilsonii->PLSC indicate migration per generation before and after hybridization between PLSC and P. wilsonii; mPLSC->ghost: migration per generation from PLSC to the ghost lineage and mghost->PLSC migration per generation from ghost lineage to PLSC. mPLSC->P. brachytyla s.s., mP. brachytyla s.s.>PLSC, mP. wilsonii-> P. brachytyla s.s. and mP. brachytyla s.s.->P. wilsonii indicate, respectively, migration per generation between P. brachytyla s.s. and PLSC or P. wilsonii in both directions. TADM1 indicates time (years) of backcrossing of the ghost lineage to P. wilsonii that gave rise to P. brachytyla s.s., while TADM2 indicates time (years) of formation of the ghost lineage between PLSC and P. wilsonii. TDIV indicates the estimated divergence time (years) between PLSC and P. wilsonii obtained from fastsimcoal2.
