Two conflicting morphological approaches to polyclad systematics highlight the relevance of molecular data for resolving the interrelationships of Polycladida. In the present study, phylogenetic trees were reconstructed based on a short alignment of the 28S rDNA marker gene with 118 polyclad terminals (24 new) including 100 different polyclad species from 44 genera and 22 families, as well as on a combined dataset using 18S and 28S rDNA genes with 27 polyclad terminals (19 new) covering 26 diffe...

The definition, as well as the existence of cryptic species, is still a subject of controversial debates. Some scientists claim that cryptic diversity is a real phenomenon that should be extensively studied while others argue that cryptic species do not exist as they are nothing more than an incompatibility of species concepts. We investigated the enigmatic case of two widely distributed Caribbean intertidal oribatid mites, Carinozetes bermudensis and Carinozetes mangrovi, consisting of five dis...

Phalangeal reduction is a common and widespread phenomenon among tortoises that has been associated with the adaptation to terrestrial life. While reduced manual digit 1 appears characteristic in almost all Testudo species, it is uncertain why the metacarpal I and distal carpal of the same digit are completely missing in some individuals of Hermann’s tortoise (Testudo hermanni hermanni). To clarify this issue, we investigated the number of manual claws in six populations of Hermann’s tortoise (o...

Known for its remarkable biodiversity and high levels of endemism, the Brazilian Atlantic Rainforest has been characterized as one of the most threatened biomes on the planet. Despite strong interest in recent years, we still lack a comprehensive scenario to explain the origin and maintenance of diversity in this region, partially given the relatively low power of analyses involving few independent genetic loci. In this study, we examine a phylogenomic dataset of five ant species to investigate ...

Brachymyrmex is a neglected genus of Formicinae because of its small body size, soft mesosoma, and superficially monotonous external morphology. These features have complicated the documentation of morphological variation, resulting in poorly defined and incompletely described species. Consequently, the taxonomy of the genus is complex and problematic, which has impeded research and conservation efforts. Here, we integrate molecular and morphological data to recognize species boundaries in Brach...

The genus Matuxia Carbayo et al., 2013 currently comprises two species with distribution restricted to southeastern Brazil. In the present study, based on an integrative approach, we examine the genetic diversity within the genus and describe a new species, Matuxia tymbyra Rossi and Leal-Zanchet, sp. nov., representing a southern lineage of the genus. We employed one mitochondrial (cytochrome c oxidase subunit I, COI) and other nuclear (elongation factor 1a, EF-1a) markers to investigate the phy...

The tribe Holcobraconini (Braconidae: Doryctinae) is a group of parasitoid wasps mainly found in the tropical and subtropical regions of the world. It contains seven genera (Holcobracon Cameron, Ivondrovia Shenefelt & Marsh, Liodoryctes Szepligeti, Monarea Szepligeti, Nervellius Roman, Odontobracon Cameron and Zombrus Marshall), most of which are characterized by having the m-cu vein of the hind wing long and strongly curved towards the apex of wing. Some studies, however, found that three doryc...

Nematodes in the Tylenchidae family are one of the most important soil-inhabiting species, yet little is known about this intriguing group. The present review examines newly collected samples of Tylenchidae from worldwide sources as well as slides from museum collections. Together with all available literature, detailed morphology among genera are summarized and compared, allowing us to explore the importance of each morphological character in a phylogenetic framework. An updated phylogeny infer...

Molecular adaptations to life on the Qinghai-Tibetan Plateau (QTP) have been detected in the genomes of many native animals, but the contribution of variations in gene expression to high-altitude adaptation remains to be determined. Here, we sequenced the peripheral blood transcriptomes of the lowland wolf and the Tibetan wolf (Canis lupus chanco), an endemic top predator on the QTP, and analyzed how the gene expression pattern has become modified to cope with the extreme plateau environments. C...

Millipedes have been inhabiting the earth for more than 400 my and show a great diversity regarding their morphology and ecology. For a better understanding of the timing and pattern of millipede evolution, Burmese amber offers a unique window into the Cretaceous period, ca. 99 Ma. Here, we describe the first known fossil of the colobognathan order Platydesmida, the species Andrognathus burmiticus n. sp. based on 15 specimens from Cretaceous Burmese amber. We combine classical light-microscopy a...
