This work is intended as a consensus list of valid tick names, following recent
revisionary studies, wherein we recognize 896 species of ticks in 3 families.
The Nuttalliellidae is monotypic, containing the single entity Nuttalliella
namaqua. The Argasidae consists of 193 species, but there is widespread
disagreement concerning the genera in this family, and fully 133 argasids will
have to be furt... hiện toàn bộ

Vocalizations of anuran amphibians have received much attention in studies of
behavioral ecology and physiology, but also provide informative characters for
identifying and delimiting species. We here review the terminology and variation
of frog calls from a perspective of integrative taxonomy, and provide hands-on
protocols for recording, analyzing, comparing, interpreting and describing these
so... hiện toàn bộ

A phylogenetic analysis of sequences from 503 species of hylid frogs and four
outgroup taxa resulted in 16,128 aligned sites of 19 genes. The molecular data
were subjected to a maximum likelihood analysis that resulted in a new
phylogenetic tree of treefrogs. A conservative new classification based on the
tree has (1) three families composing an unranked taxon, Arboranae, (2) nine
subfamilies (fiv... hiện toàn bộ

The Muscidae (Diptera) of the Neotropical Region are catalogued. 843 extant and
3 extinct species in 84 genera are listed together with their synonyms, giving a
total of 1209 names. References are given to the original descriptions and the
subsequent taxonomic, biological and applied literature, the location of types,
and the geographic distribution. A comprehensive bibliography is provided. There... hiện toàn bộ
The order Cypriniformes is the most diverse order of freshwater fishes. Recent
phylogenetic studies have approached a consensus on the phylogenetic
relationships of Cypriniformes and proposed a new phylogenetic classification of
family-level groupings in Cypriniformes. The lack of a reference for the
placement of genera amongst families has hampered the adoption of this
phylogenetic classification... hiện toàn bộ
The invasion of the pheretimoid earthworms in North America, especially the
genera Amynthas and Metaphire, has raised increasing concerns among ecologists
and land managers, in turn increasing the need for proper identification.
However, the commonly used keys to this group are more than 30 years old with
outdated taxonomic information and are based primarily on internal morphology.
The requiremen... hiện toàn bộ

The small nurse frogs of the genus Allobates (Anura, Aromobatidae) represent one
of the most challenging taxonomic issues of the Neotropics. During several
amphibian surveys in the Middle Tapajós River region, state of Pará, Brazil, we
collected phenotypic, ecological, and molecular data on species of this genus,
leading to the identification of a new species included in the Allobates

Gobio baliki, new species, is described from the stream Büyük Melen in the
northwestern Anatolian Black Sea basin. The new species is distinguished from
other gudgeons in Anatolia by the breast being completely covered by scales,
scales extending slightly behind the isthmus; 5–6 scales between the posterior
extremity of the pelvic-fin base and the anus; the distance between the anus and
the anal-f... hiện toàn bộ

A new early dinosaur, Unaysaurus tolentinoi gen. et sp. nov., from the
continental Late Triassic red beds of the Caturrita Formation (Carnian-Norian,
c. 225 million years old) of southern Brazil is described. U. tolentinoi is
represented by a semi-articulated skeleton comprising an almost complete skull,
lower jaw and postcranial elements. It differs from all other dinosaurs by
several cranial (e.... hiện toàn bộ
