Phylogeny of harvestmen family Gonyleptidae inferred from a multilocus approach (Arachnida: Opiliones)
TLDR
The traditional use of a small set of morphological characters in the systematics of Gonyleptidae is unable to explain the complex evolution of the family.
Molecular phylogeny of Geoplaninae (Platyhelminthes) challenges current classification: proposal of taxonomic actions
TLDR
A phylogenetic hypothesis for selected taxa of Geoplaninae based on the molecular data is presented and discussed in the light of morphological features, and a number of well‐supported clades are unveiling morphologically homogeneous groups.
Phylogeny, biogeography, and electric signal evolution of Neotropical knifefishes of the genus Gymnotus (Osteichthyes: Gymnotidae).
TLDR
Phylogenetic optimization of electric signal waveforms indicate that the ancestral state in Gymnotus is a multiphasic (4+phases of alternating polarity) condition, and independent phase loss has occurred in multiple lineages.
Diversification and Species Boundaries of Rhinebothrium (Cestoda; Rhinebothriidea) in South American Freshwater Stingrays (Batoidea; Potamotrygonidae)
TLDR
The level of intra-specific morphological variation observed in features such as total length and number of proglottids is unparalleled among other elasmobranch cestode species, which is attributed to the large representation of host and biogeographical samples.
Phylogeny and taxonomy of Potamotrygonocotyle Mayes, Brooks & Thorson, 1981 (Monogenoidea: Monocotylidae) with a description of four new species
TLDR
It is found that hypotheses of species delimitation depend greatly on efforts to sample specimens throughout its distributional range and that host specificity within this genus varies dramatically among lineages.
Systematics and phylogeny of Potamotrygonocestus (Platyhelminthes, Tetraphyllidea, Onchobothriidae) with descriptions of three new species from freshwater potamotrygonids (Myliobatoidei,
TLDR
A phylogenetic analysis of six morphological characters for the six named species of Potamotrygonocestus generated a single tree eight steps long, with a consistency index of 0.87, a retention index of0.90, and a rescaled consistency indexof 0.79.
ON THE LARVAL STAGES OF MACROCOELOMA DIPLACANTHUM (DECAPODA: BRACHYURA: MAJIDAE), AND A REVIEW OF MITHRACINE PHYLOGENETIC ASPECTS
TLDR
Larval development of Macrocoeloma diplacanthum (Stimpson) consists of two zoeal stages, followed by the megalopa, which is remarkably consistent with Floridian specimens previously described.
Phylogenetic analysis of the Pinnotheridae (Crustacea, Brachyura) based on larval morphology, with emphasis on the Dissodactylus species complex
TLDR
Larval and adult morphology suggested that Pinnotheres politus should be included within Tumidotheres, and that the traditional subfamilial arrangement comprises paraphyletic taxa within the subfamilies Pinnotherinae and Pinnothereliinae.
