To select the best characters for cladistic analysis, the resulting data matrix (Appendix 2, characters 1-31, no missing data) was analyzed using the computerized parsimony program Hennig86, using the search options mh* and bb*, a heuristic method for finding minimum-length trees that retains all the shortest trees, and a strict consensus tree was obtained by applying the NELSEN command of Hennig86 (Farris, 1988).
