Phylogeny of the family StreptaxidaeStaff: Ben Rowson
The Streptaxidae (Pulmonata: Sigmurethra/Achatinoidea) are a paleo- and neo-tropical family of presumptive obligate carnivorous, largely ground-dwelling land-snails. Great site and regional diversity in streptaxids, coupled with range-size rarity, is seen in East Africa where morphological (shell) diversity is extremely high. As a result of the surveys carried out in Kenya and Tanzania, the collections hold good material for a widespread taxonomic revision of this group. Ben Rowson, with Bill Symondson & Michael Brufford (University of Cardiff) is currently studying the systematics of the land-snail family Streptaxidae using morphological and molecular techniques. Phylogenetic and biogeographical hypotheses will be tested once a phylogeny is inferred.
