Resolution & conflict, I

Adding some additional characters still at a relatively superficial level, things that stood out even during the initial descriptions. There is a total of 15 characters at this point (Cotithene4.winc). The monophyly of Cotithene appears well supported; same for Terioltes. The two synapomorphies previously postulated for a Cotithene-Terioltes clade, although less clear-cut, also appear to hold up.

Within Cotithene there are two relatively obvious pairs of closely related species: ana+met & lep+tri. There is also some initial conflict since ana has (according to the first descriptions) three small triangular projections in the male frontal head region which is shares with globulicollis & str, thereby indicating a conflicting grouping. Rechecking of characters is needed.
