Our FOG approach revealed two equally parsimo- nious trees, each with 53 steps (=58 steps with HA; CI = , RI = ). Neither tree was the same as resolved from our SAW evaluation but both were among our original ten MPTs. The strict consensus tree shows two unresolved nodes (Fig. 4). For resolv- ing the ambiguous nodes, a closer FOG, Oreoialax lichuanensis, was selected. Taxa below the FOG (O. rhodostigmatus. O. popei and O. omeimontis) were excluded from this analysis. A single MPT with 37 steps was found (=58 steps with the deleted taxa; CI = , RI = ) (. 5). It is one of the ten MPTs from the original analysis. Examination of character state distributions on this tree showed no potential for fur- ther resolution to the relationships of O. chuanbeien- sis, O. liangheiensis and more terminal taxa. Combining the results of our progressive FOG analy- sis, a single cladogram emerged as our preferred tree (Fig. 6). Thus, our tree is left with one unresolved polytomy. Bootstrap (BS; Felsenstein 1985: Siddall 1994) was used to assess strength of support of monophyl- etic groups. The BS value based on 999 randomized data sets was mapped on the resulting tree (Fig. 6). Three nodes were shown to be well supported by BS that have values over The O. schmidti and O. iongensis clade has a highest value of while the O. jingdongensis, and O. granulosus clade has the second highest value of The ingroup member excluding O. rhodostigmatus from the clad
