Hi Was reading your conversation with big interest. I have been thinking about this since I´m very interested in the southern species as Borellii, Commbrae and Trifasciata. I would like to have some comments to my thoughts below. As I understand the development of species within a genera moves in the direction of more and more specialized species. And would say that the amazon basin inhibit a lot of highly specialized apisto species, while the paraguay/ parana basin is not. The three endemic species (Borellii, Commbrae and Trfasciata) in the paraguay/ Parana basin are regarded as non-specialised highly oppurtunistic species. (As far as I understand). Wouldn´t that also confirm the theory that these species have migrated from north to south in a relatively late period? Best regards/ Per --------------------------------- Yahoo!
