Cladistic Analysis of the Paleozoic Bryozoan Families Monticuliporidae and Mesotrypidae
… for 267 morphological attributes were coded. Cladistic results were compared between the programs PAST and PAUP, and contrasted with phenetic methods. PAUP produced the shortest trees, with better summary index values and low homoplasy. Phenetic results varied, depending largely on the …

Tracing Ainu and Pre-Ainu Cultural Continuity Through Cladistic Analysis of Faunal Assemblages
Cladistics (Hennig 1950, 1965, 1966), a method for establishing evolutionary relationships, is used to compare faunal assemblages from Jōmon (14,000-500 BC; 14,000–2700 cal. BP), Epi-Jōmon (3rd – 7th century; 2700-1500 cal. BP), Satsumon (7th century - 13th century AD; ca. 1500-800 cal. BP), and …

The Sphegigasterini: A Cladistic Analysis and Generic Classification With Reviews of Selected Genera (Hymenoptera: Pteromalidae)
The Sphegigasterini sensu strictu (Boucek, 1988) is defined by the possession of a basal flange on the petiole. The history of the genera belonging to the Sphegigasterini sensu strictu is reviewed. The author's intuitive classification of the genera is given.

Systematic and evolutionary studies of Acacia series Gummiferae (Fabaceae: Mimosoideae)
… series that are endemic to the West Indies, a cladistic analysis of chloroplast DNA restriction site variation of members of Acacia series Gummiferae and related taxa, and a cladistic analysis of morphological data of Acacia series Gummiferae. The results were used to draw conslusions regarding …

Phylogenetic Analysis of Certain Lower Brachycerous Diptera in the Nearctic Region
… is compared with one produced by a rooted Wagner cladistic analysis and by three phenetic analyses: the Pearson product-moment correlation coefficient, the average taxonomic distance, and the mean character distance. Six out-group genera are included for purposes of comparison.

Phylogeny, Classification, and Biogeography of the Cycloteline Therevinae (Diptera: Therevidae)
… using 65 adult morphological characters. Cladistic analysis using parsimony on the 17 ingroup and 4 outgroup taxa provides a well supported hypothesis of relationships among taxa within the Cyclotelini, tribe nov. The Cyclotelini is a monophyletic assemblage of mostly New World genera, …

Taxonomy of the Neotropical Thorny Catfishes (Siluriformes: Doradidae) and Revision of Genus Leptodoras
Cladistic analysis of relationships among Leptodoras and related taxa (Anduzedoras, Doras, Hassar, Hemidoras) using morphological data recovers Leptodoras praelongus (Myers & Weitzman) as the most ancestral species. The most derived clade is composed of two nominal species, Leptodoras juruensis …

Morphology, phylogeny, and evolutionary development in the weevils (Insecta: Coleoptera: Curculionoidea)
… to incorporate numerous fossils into a formal cladistic analysis. In order to develop a more robust morphological character system for cladistic analysis of the higher lineages and to gain a comprehensive understanding of rostrum structure prior to developmental studies examining its formation, …

A revision of Otholobium C.H. Stirton (Papilionoideae, Leguminosae)
… chemistry, pollen anatomy and morphology. A cladistic analysis was made of the genera in the Psoraleeae.

Systematics of the spider genera Mallos and Mexitilia (Arameae: Dictynidae)
… species are described for the first time. A cladistic analysis based on 22 morphological produced a cladogram that supports the monophyly of Mallos and the validity of Mexitilia. For five species of Mallos and one species of Mexitilia mitochondrial and nuclear DNA sequences were analyzed by …

Bithoracochaeta Stein, 1911 (Diptera, Muscidae): revisão das espécies e análise cladística
… of the redescribed species is presented. A cladistic analysis was made using the program Hennig86 based on 17 caracters and 3 out-groups. Based on the cladogram, the phylogenetic relationships among the species of this genus are shown.

Revisão taxonômica e análise filogenética das espécies do gênero neotropical Balacha Melichar (Insecta, Hemiptera, Cicadellidae, Cicadellinae)
… fmale specimens of Balacha is also provided. A cladistic analysis of the known species of Balacha and eleven related outgroup taxa, based on 64 morphological characters, corroborates the hypothesis of monophyly of the genus and its sister group relationship to Pegogonia Young.

Studies in the Dryopteris inaequalis (Dryopteridaceae) complex
… phylogeny of the complex is reconstructed using cladistic analysis of morphological characters. Dryopteris manniana (Hook.) C.Chr., the probabl sister species is used as an outgroup for the analysis. Phylogenetic analysis revealed that there are four monphyletic species and two metataxa in the …

Relações filogenéticas da subfamília Didelphinae: padrões de variação da morfologia crânio-dentária (Marsupialia: Didelphidae)
Used a cladistic analysis to evaluate the phylogenetic relationships among living and fossil genera of the Subfamily Didelphinae. Four different genera were used as outgroups: Caluromys (Caluromyinae, Didelphidae), Sparassocynus (Sparassocynidae), Caenolestes (Caenolestidae) e Dromiciops …

Relações filogenéticas entre os táxons basais da família Trichomycteridae (Siluriformes : Loricarioidea)
… morphological characters and bibliography. After cladistic analysis (length = 117; consistency index = 0.75; retention index = 0.78) of 63 characters, among 12 terminal taxa, is evident that Copionodontinae and Trichogeninae form a monophyletic group, based on 13 sinapomorphies. These are: …

Análise filogenética das espécies de Castoraeschna Calvert, 1952 (Insecta, Odonata, Aeshnidae)
Cladistic analysis including adult representatives of the eight described species of Castoraeschna and four species of the related genera Coryphaeschna, Remartinia and Rhionaeschna, based on 118 morphological characters, is presented. Four different fully resolved trees were obtained using the …

Systematics of psilocaulon N.E.BR. (Aizoaceae)
… Aspazom and Aptenia are used as outgroups in a cladistic analysis of Psilocaulon. The monophyly of Psilocaulon is demonstrated. As a result P. rapaceum Jacq. is excluded and transferred to Caulipsolon Klak gen. nov. The position of Psilocaulon and the monotypic genus Caulipsolon within the …
