Subfamily Monographinae

Parsimony analyses show Monographinae ( Monographis , Unixenus , Eudigraphis ) to be paraphyletic ( Figure 3 ) whereas the ML analysis ( Figure 2 ) indicates monophyly of the group (BS <50%). This may be partly a result of the incompleteness of the molecular data set, with only CO1 sequences available for the six Eudigraphis specimens.

Mean pairwise distances between the genera Monographis and Unixenus are 17.3% (COI) and 1.2% (18S), between Monographis and Eudigraphis 17.4% (COI only) and between Unixenus and Eudigraphis 15.5% (COI only).

Figure 2. Optimal maximum likelihood tree (lnL = −10,376.678214) based on molecular data (COI, 16S, 18S). Bootstrap support values (> 50%) shown on the nodes. Thelytokous populations of P. novaehollandiae (Silvestri, 1923) and the one confirmed thelytokous population of Polyxenus lagurus (Linnaeus, 1758) are marked with an asterisk.

Figure 3. Strict consensus of 626 MP trees based on combined morphological and molecular data. Jackknife (JF) support values (> 50%) shown above the nodes (in parentheses, JF values based on molecular data only). Thelytokous populations of Phryssonotus novaehollandiae (Silvestri, 1923) and the one confirmed thelytokous population of Polyxenus lagurus (Linnaeus, 1758) are marked with an asterisk.
