Phylogeny of Calamoceratidae

The objectives of this project are:

1. to identify sister group relationships for phylogenetic analysis of Neotropical species;

2. to test the monophyly of Calamoceratidae and hypotheses of within-family relationships;

3. to generate a phylogeny on which to map case structure.

The Calamoceratidae consists of 100+ species placed in 9 genera (one of which one we have moved to the family Pisuliidae). Most species are tropical. Synapomorphies for genera have not previously been identified.

To accomplish the above objectives, I selected exemplar taxa from each genus. I examined at least 4 specimens of each taxon and scored 100+ morphological characters. I then used parsimony analysis to generate hypotheses of relationship.
