Morphological phylogeny of cobweb spiders and their relatives (Araneae, Araneoidea, Theridiidae)
This paper offers the first cladistic analysis of a wide selection of theridiid genera based on morphological data. The analysis treats 53 theridiid taxa representing 32 genera ( Achaearanea , Anelosimus , Ameridion , Argyrodes , Ariamnes , Carniella , Cerocida , Chrysso , Coleosoma , Dipoena , Emertonella , Enoplognatha , Episinus , Euryopis , Faiditus , Kochiura , Latrodectus , Neospintharus ...
متن کاملMorphology and Evolution of Cobweb Spider Male Genitalia (araneae, Theridiidae)
This study elucidates the homology of elements of the male palps in the spider family Theridiidae. We survey and illustrate 60 species from 29 out of the 86 currently recognized genera representing all subfamilies. The study is buttressed by a phylogenetic framework, and uses a new method to evaluate critically competing homology hypotheses based on various criteria. Among the classic criteria ...
متن کاملThe phylogeny of the social Anelosimus spiders (Araneae: Theridiidae) inferred from six molecular loci and morphology.
We use fragments of three nuclear genes (Histone 3, 18SrDNA, and 28SrDNA) and three mitochondrial genes (16SrDNA, ND1, and COI) totalling approximately 4.5kb, in addition to morphological data, to estimate the phylogenetic relationships among Anelosimus spiders, well known for their sociality. The analysis includes 67 individuals representing 23 of the 53 currently recognized Anelosimus species...
متن کاملGenera of euophryine jumping spiders (Araneae: Salticidae), with a combined molecular-morphological phylogeny.
Morphological traits of euophryine jumping spiders were studied to clarify generic limits in the Euophryinae and to permit phylogenetic classification of genera lacking molecular data. One hundred and eight genera are recognized within the subfamily. Euophryine generic groups and the delimitation of some genera are reviewed in detail. In order to explore the effect of adding formal morphologica...
متن کاملPhylogeny of entelegyne spiders: affinities of the family Penestomidae (NEW RANK), generic phylogeny of Eresidae, and asymmetric rates of change in spinning organ evolution (Araneae, Araneoidea, Entelegynae).
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 morphology of the male pedipalp, which features (among other things) a retrolateral tibial apophysis (RTA). The presence of an RTA is synapomorphic for a large clade of spiders exclusive of Eresidae. A molecular data matrix based ...
