Several extensions to implied weighting, recently implemented in TNT, allow a better treatment of data sets combining morphological and molecular data sets, as well as those comprising large numbers of missing entries (e.g. ...

The family Characidae, including more than 1000 species, lacks a phylogenetic diagnosis, with many of its genera currently considered as incertae sedis. The aims of the present study are to propose a phylogenetic diagnosis ...

A likelihood method that approximates the behaviour of implied weighting is described. This approach provides a likelihood perspective on several aspects of implied weighting, such as guidance for the choice of concavity ...

The Neotropical lycaenid hairstreak genus Thepytus Robbins and its eight species are revised. Species treatments summarize nomenclature, distribution, habitat, behavior, and diagnostic traits, as well as noting why each ...

This study evaluates the phylogeny of ray-finned fishes (Actinopterygii) combining most available information (44 markers from nuclear and mitochondrial DNA and 274 morphological characters). The molecular partition of the ...

El género Bostryx Troschel, 1847 es encontrado exclusivamente en Sudamérica, desde Ecuador hasta Chile, principalmente en relación a la cordillera de los Andes. La filogenia de Bostryx está basada en caracteres morfológicos ...

Tipulomorpha (craneflies) comprise one of the largest subgroups of Diptera, but its phylogeny at different levels has been poorly explored. This study presents the most comprehensive cladistic analysis of the group ever ...

Stevardiinae, which consists of 326 species and 44 genera, is a monophyletic subfamily within the family Characidae. In a recent classification of the subfamily, the tribe Stevardiini was expanded from three (Corynopoma, ...

This study aimed at testing the utility of characters derived from chitinous structures of the sting apparatus for elucidating relationships among the genera of Epiponini. The characters were obtained from the spiracular ...
