In the last decade and a half, advances in genetic sequencing technologies have
revolutionized systematics, transforming the field from studying morphological characters or …

We present a phylogenetic analysis of spiders using a dataset of 932 spider species,
representing 115 families (only the family Synaphridae is unrepresented), 700 known …

ABSTRACT A phylogenetic analysis of the two-clawed spiders grouped in Dionycha is
presented, with 166 representative species of 49 araneomorph families, scored for 393 …

El libro tiene una estructura tan simple como su título. Tras unos capítulos iniciales
introductorios, siguen los de claves de identificación y 107 subcapítulos dedicados cada …

The importance of morphology in the phylogenomic era has recently gained attention, but
relatively few studies have combined both types of information when inferring phylogenetic …

Lycosids are a diverse family of spiders distributed worldwide. Previous studies recovered
some of the deeper splits of the family, but with little support. We present a broad …

South America is the fourth largest continent on the planet; its birds, mammals, and
amphibian's biodiversity is relatively well known, but no outright assessment of the continent …

Penestomine spiders were first described from females only and placed in the family
Eresidae. Discovery of the male decades later brought surprises, especially in the …

The structures with which male spiders transfer sperm to females are unique among all
animals in several respects. From the ancestral arachnid sperm transfer mechanism via an …

Phylogenetic relationships within the superfamily Lycosoidea are investigated through the
coding and analysis of character data derived from morphology, behaviour and DNA …
