Revision And Reclassification Of The Genera Of Phalacridae (Coleoptera: Cucujoidea), Matthew Gimmel
Revision And Reclassification Of The Genera Of Phalacridae (Coleoptera: Cucujoidea), Matthew Gimmel
LSU Doctoral Dissertations
The family Phalacridae is monographed at the genus level using modern phylogenetic and classification methods. A morphological matrix of 106 characters and 2063 base pairs of aligned 18S rDNA sequence data were analyzed both separately and in a concatenated matrix, using maximum parsimony, Bayesian methods, and maximum likelihood. The phylogenetic hypotheses were used to construct a new subfamilial classification for the family. I recognize eight subfamilies, including two described as new: Biophytinae Guillebeau 1894, Eustilbinae Guillebeau 1892, Ochrolitinae Guillebeau 1894, Olibrinae Guillebeau 1892, Olibroporinae, subfam. nov., Olibrosominae, subfam. nov., Phaenocephalinae Matthews 1899, Phalacrinae Guillebeau 1892. Twenty-eight new generic synonymies are …
Revision Of Pocadius Erichson (Coleoptera: Nitidulidae), Andrew R. Cline
Revision Of Pocadius Erichson (Coleoptera: Nitidulidae), Andrew R. Cline
LSU Doctoral Dissertations
A revision of Pocadius Erichson (Coleoptera: Nitidulidae) was completed. A total of 46 species were (re)described, including 25 new species, a key to species constructed, and phylogenetic analysis performed. Taxonomic changes, including nomenclatural emendations, reinstatement of species, and description of new taxa, within this dissertation do not constitute formal changes as defined by the International Code of Zoological Nomenclature. Illustrations of the genitalia, key characters, and dorsal habitus of species are provided. The phylogeny demonstrates a monophyletic Pocadius. The phylogeny suggests a Palearctic origin of the genus with subsequent speciation into the Old World tropics and New World. Host specialization …
