Taxonomic Revision of the Genus Bothus (Bothidae; Pleuronectiformes)
The taxonomic status of its 59 nominal species of the genus Bothus (Pleuronectiformes: Bothidae) has been revised, based on a morphological study of 320 type and non-type specimens. Of the 59 nominal species examined in the study, 18 have found to be valid and are re-described. The genus Bothus …

A taxonomic revision of the Nearctic species of the genus Bezzia (Diptera: ceratopogonidae)
This study is intended as a collective standardization of descriptions and illustrations of the species of Bezzia in the Nearctic Region. Forty-three species are reviewed, 14 of which are new. Two species are thought to be junior synonyms. A new subgeneric name, Aspinabezzia, is proposed for the …

A taxonomic revision of the spiny members of subfamily celastroideae (Celastraceae) in Southern Africa
A taxonomic revision of all the southern African spiny members of the Celastroideae is presented. Evidence from macromorphology, leaf anatomy, ecology and phytogeography is used as a basis for classification. The genus Gymnosporia (Wight & Am.) Hook. f. is reinstated, deviating from Maytenus by the …

A taxonomic revision of the squat lobsters (Anomura: Chirostyloidea and Galatheoidea) of South Africa
… the fauna were made almost 20 years ago. Thus, a revision of these superfamilies is long overdue. This study relied on examination of historic material housed in the Natural History Collections of the Iziko South African Museum, as well as ad-hoc sampling to carry out morphological analyses and …

Systematics of Tridactyloidea (Orthoptera: Caelifera): Taxonomic revision of extinct taxa with comments on extant taxa
… However, the monophyly of families and other taxonomical subcategories have not been resolved. My goal was to provide a stable taxonomy for this group by developing robust phylogenetic hypotheses with a total evidence approach. Specifically, I aimed to produce a taxonomic revision of fossils …

Taxonomic Revision of the Pirate Perches (Percopsiformes: Aphredoderidae) Reveals Three New Species and Elevates Two Subspecies
The Southeastern United States is home to exceptionally high fish diversity among temperate latitudes. Species richness and endemism in this region is commonly attributed to historic biogeographic processes dating back to the Pliocene or earlier, and influences of sea levels through a relatively …

Taxonomic revision of taxa originally described in Leptosphaeria from species in the Ranunculaceae, Papaveraceae and Magnoliaceae
… study are as follows: first, completion of a taxonomic revision of the species of Leptosphaeria described from plant species in Ranunculaceae, Papaveraceae and Magnoliaceae; second, completion of a taxonomic revision of L. vagabunda and its infraspecific taxa. Twenty-six taxa described from …

More than meets the eye: A taxonomic revision of the Nearctic species in the eye-gnat genus Amiota Loew (Diptera: Drosophilidae)
… such as North America. This thesis presents a taxonomic revision of the Nearctic species of the genus <em>Amiota</em> Loew. Twenty-three species are identified as being new to science for publication at a later date. This increases the total species known in the Nearctic to 34. <em>Amiota …

A morphological phylogeny with a taxonomic revision of African species of Goniodes (Insecta: Phthiraptera: Ischnocera) sensu lato from the Galliformes (Aves)
… supported apical groups cannot from a gross taxonomic perspective be effectively “described/circumscribed” in light of morphology alone. It is thus apparent that the reality of the biological complexities associated with ubiquitous morphological convergence in the Ischnocera at large, and …

Molecular phylogeny, generic delineation, and historical biogeography of Cryptocheilus Panzer, 1806 and Heterodontonyx Haupt, 1935 with taxonomic revision of Australian species using mitochondrial genes, the ribosomal operon and UCE loci
… and Heterodontonyx, have had a problematic taxonomic history due to their morphological similarity and affinities to the Palaearctic genera. My project aims to: 1-delineate the two morphologically similar Cryptocheilus and Heterodontonyx, 2- build a molecular phylogeny of Cryptocheilus and …

Studies of the South African species of Eulophia R. Br. ex. Lindl. (Orchidaceae)
… work was undertaken to provide a much-needed taxonomic revision of the South African members of the genus Eulophia R.Br. ex Lindl. (Orchidaceae). To obtain data for delimiting and giving rank to taxa, studies were made of morphological variation, geographical distribution, cytology and ecology.
