letic with respect to his trisetosus group
(fig. 15). To avoid unnecessary multiplication
of species groups, we propose to group all of
the lineages in the sister group of Decellea
into a more widely circumscribed trisetosus
species group.
In the new scheme, two very distinct
species from the Far East form the small
apeosus group, while its sister clade is
subdivided into two groups, the ruficollis
and the punctulatus groups. The species
groups ruficollis and zonatus sensu Ronquist
make up the ruficollis group of the present
study. Although the zonatus group sensu
Ronquist still holds as a monophyletic clade
in the present phylogeny, it nests within the
ruficollis group and we prefer letting the
zonatus species be subsumed into the ruficollis
group over splitting the relatively few
species in the latter group.
Finally, species of the groups borneanus
and punctulatus sensu Ronquist are united
here into the large, yet morphologically
homogeneous and geographically restricted
