The genus Argyrodiaptomus was studied with the description of a new specie and
comparison with the other species. 369 items were listed using the DELTA program for the
production of descriptions, identification keys and a characters matrix. 72 characters were
more informative, and the polarization of them were made a priori. Notodiaptomus deitersi
e Aspinus acicularis were used as outer groups. The matrix was converted from the DELTA
format to HENNIG86 and Nexus formats. Then the programs PAUP and Winclada were
used to process the matrix with a heuristic search for the most parsimonious tree. The
analysis resulted in one most parsimonious tree, with the following phylogenetic statistic
indexes: (L)=109, (CI)=0.954 and (RI)=0,954. The monophily of the group was sustained
by 23 synapomorphies, and the resulting phylogenetic relationships between species of
Argyrodiaptomus are: (((A. azevedoi, A. robertsonae, A. nhumirim e A. sp.) ((A. furcatus,
A. macrochaetus) (A. argentinus, A. denticulatus))). |
