Apioceridae (Insecta: Diptera): cladistic reappraisal and biogeography

Utilizing online resources for taxonomy: a cybercatalog of Afrotropical apiocerid flies (Insecta: Diptera: Apioceridae)

A cybercatalog to the Apioceridae (apiocerid flies) of the Afrotropical Region is provided. Each taxon entry includes links to open-access, online repositories such as ZooBank, BHL/BioStor/BLR, Plazi, GBIF, Morphbank, EoL, and a research web-site to access taxonomic information, digitized literature, morphological descriptions, specimen occurrence data, and images. Cybercatalogs as the one pres...

Contributions of Cladistic Biogeography to the Mexican Transition Zone

Cladistic biogeography of Gleditsia (Leguminosae) based on ndhF and rpl16 chloroplast gene sequences.

We used cladistic analysis of chloroplast gene sequences (ndhF and rpl16) to test biogeographic hypotheses in the woody genus Gleditsia. Previous morphological comparisons suggested the presence of two eastern Asian-eastern North American species pairs among the 13 known species, as well as other intra- and inter-continental disjunctions. Results from phylogenetic analyses, interpreted in light...

Phylogeny and biogeography of the genus Piezura Rondani (Diptera: Fanniidae)

The Holarctic genus Piezura Rondani (Diptera, Fanniidae) is reviewed. Phylogenetic relationships among the species in this group, as well as the biogeography of these species, are discussed on the basis of a cladistic analysis. Piezura graminicola shanxiensis Xue, Wang and Wu, 1998 is redescribed and elevated to species rank based on comparison of its morphology and phylogenetic relationships. ...

Phylogeny and biogeography of the genus Pelinoides Cresson (Diptera-Ephydridae)

A phylogenetic analysis of the 21 species of genus Pelinoides using 44 discrete morphological characters is presented. From the previous proposed three groups, pallipes, sulcatus and cyclocerus, the first is recovered. The sulcatus group appears as paraphyletic in terms of cyclocerus. Pelinoides is present in the Neotropical and Andean Regions and in the Transitional South American Zone. Four a...
