Morphological phylogeny of cobweb spiders and their relatives (Araneae, Araneoidea, Theridiidae)
- I. Agnarsson
- 1 August 2004
The results suggest the monophyletic origin of both kleptoparasitism and araneophagy in the lineage leading to Argyrodinae, negating hypotheses that either arose from the other.
Undersampling bias: the null hypothesis for singleton species in tropical arthropod surveys.

The lognormal distribution deserves greater consideration as a richness estimator when undersampling bias is severe, and should be the default null hypothesis for singleton frequencies.
A revision of the New World eximius lineage of Anelosimus (Araneae, Theridiidae) and a phylogenetic analysis using worldwide exemplars
- I. Agnarsson
- 1 April 2006
A revision of the New World ‘eximius lineage’ containing the most intensely studied Anelosimus species, and a phylogenetic study including worldwide exemplars, corroborate previous findings of convergent evolution of permanent sociality in the genus.
The phylogeny of Cetartiodactyla: the importance of dense taxon sampling, missing data, and the remarkable promise of cytochrome b to provide reliable species-level phylogenies.
Phylogenomics Resolves a Spider Backbone Phylogeny and Rejects a Prevailing Paradigm for Orb Web Evolution
Reconstructing web evolution and spider diversification in the molecular era

- 31 March 2009
A broad higher-level phylogeny of spiders is constructed combining molecular data with traditional morphological and behavioral characters to test the hypothesis that the spider orb web evolved only once, and finds strong support for a single origin of orb webs.
Shark tales: a molecular species-level phylogeny of sharks (Selachimorpha, Chondrichthyes).
Cytochrome b and Bayesian inference of whale phylogeny.
Spider phylogenomics: untangling the Spider Tree of Life
Contrary to long held beliefs that the orb web is the crowning achievement of spider evolution, ancestral state reconstructions of web type support a phylogenetically ancient origin of the orbweb, and diversification analyses show that the mostly ground-dwelling, web-less RTA clade diversified faster than orb weavers.
