ONOMASTUS RELATIONSHIPS

The phylogenetic analysis of the above-mentioned, equally weighted characters performed in NONA (hold10000; hold/200; 1000 replicates of tree bisection-reconnection (TBR) + TBR (mult*1000) produced one tree of minimal length. Analysis of the same data set in PAUP with heuristic search methods (100 replicates of random taxon addition subjected to TBR branch swapping; ‘MulTrees’ set to 100000; branches collapsed if the minimum possible branch length was zero (‘amb-’; ACCTRAN or Farris optimization) produced the same minimal length tree found with NONA. This tree was selected as the preferred phylogenetic hypothesis for Onomastus ( Fig. 1 ). Onomastus is resolved at node 3 supported by four unambiguous synapomorphies. Within Onomastus , species are grouped into two clades, which are named here as the South Asia clade (SA clade) which includes species from Sri Lanka and India and the South-East Asian clade (SE clade), which includes the remaining diversity.

Figure 1. Preferred most parsimonious tree of Onomastus based on the character matrix presented in Table 1 (length = 32 steps, consistency index = 0.81, retention index = 0.89). Character state changes are mapped using Farris optimization. Closed circles represent unambiguous character changes.
