Farfantepenaeus subtilis (Pérez-Farfante, 1967) and F. brasiliensis (Latreille, 1817) (Decapoda, Penaeidae): Ontogenetic comparison using the combined analysis of secondary sexual characters and molecular markers
(2019-08-01)
Most identification keys of species of Farfantepenaeus use the shape of secondary sexual characters as a dichotomic character, but this approach focus only on adults. The lack of similar diagnostic tools for juveniles, ...
A new genus and three new species of Neotropical Tanyproctini (Coleoptera: Scarabaeidae: Melolonthinae)
(Magnolia Press, 2012-04)
A new genus of scarab beetle, Eideria Neita & Ocampo, and three new species, E. pentaphylla Neita & Ocampo, E. glabripenis Neita & Ocampo, and E. pedroantonioi Neita & Ocampo, are described based on specimens collected in ...
Systematics value of micromorphological and palynological characters in stenocephalum Sch. Bip (vernonieae, asteraceae)
(Tubitak Scientific & Technical Research Council Turkey, 2018-05)
Micromorphological and palynological characters of all Stenocephalum Sch.Bip. species (Vernonieae, Asteraceae) were analyzed to evaluate their reliability as taxonomic markers at generic level and discussed in relation to ...
Phylogenetic position of Argentinian and Chilean endemic species of Senecio ser. Culcitium (Asteraceae) with an evolutionary analysis of morphological characters
(Magnolia Press, 2019-01-09)
In its current circumscription, Senecio ser. Culcitium Cabrera, which includes ca. 40 South American species, is characterized by discoid, sometimes nodding capitula, calycular bracts resembling a multiseriate involucre, ...
The importance of molecular characters when morphological variability hinders diagnosability: systematics of the moon jellyfish genus Aurelia (Cnidaria: Scyphozoa)
(PeerJ Inc., 2021-09)
Cryptic species have been detected across Metazoa, and while no apparent morphological features distinguish them, it should not impede taxonomists from formal descriptions. We accepted this challenge for the jellyfish genus ...
Taxonomia e filogenia de Plistonax Thomson, 1864 (Coleoptera, Cerambycidae, Lamiinae)
(Universidade Federal de Minas GeraisBrasilICB - DEPARTAMENTO DE ZOOLOGIAPrograma de Pós-Graduação em ZoologiaUFMG, 2020-02-17)
The family Cerambycidae is one of the most diverse groups of the order Coleoptera, comprising about 36,000 species. The taxon is divided into eight subfamilies, and Lamiinae is the most representative, with more than 21,000 ...
A synopsis of the South American genus Gomphomacromia (Odonata: Gomphomacromiinae)
(Taylor & Francis, 2005-12)
Gomphomacromia mexicana is shown to be a junior synonym of G. chilensis based on a comparison of the holotype male with the original description of G. chilensis and specimens identified as that species from Chile. Examination ...
Leaf characters of Lavoisiera, Microlicia and Trembleya (Microlicieae, Melastomataceae) and their implications for taxonomy
(2018-06-01)
In Microlicieae taxonomical delimitation of Lavoisiera, Microlicia and Trembleya is problematic. This study aims to fill this gap by identifying leaf characters that are useful for taxonomy of these genera. Species of ...
The importance of molecular characters when morphological variability hinders diagnosability: Systematics of the moon jellyfish genus Aurelia (Cnidaria: Scyphozoa)
(2021-09-09)
Cryptic species have been detected across Metazoa, and while no apparent morphological features distinguish them, it should not impede taxonomists from formal descriptions. We accepted this challenge for the jellyfish genus ...
Combined phylogeny of ray-finned fishes (Actinopterygii) and the use of morphological characters in large-scale analyses
(Wiley Blackwell Publishing, Inc, 2017-08)
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 ...
