The female genital morphology of the orb weaving spider genus Agriognatha (Araneae, Tetragnathidae).

The phylogenetic basis of sexual size dimorphism in orb-weaving spiders (Araneae, Orbiculariae).

Extreme sexual body size dimorphism (SSD), in which males are only a small fraction of the size of the females, occurs only in a few, mostly marine, taxonomic groups. Spiders are the only terrestrial group in which small males are relatively common, particularly among orb-weavers (especially in the families Tetragnathidae and Araneidae) and crab spiders (Thomisidae). We used a taxonomic sample ...

A new orb-weaving spider from the Argentinean flooding pampas grasses: Aculepeira morenoae new species (Araneae, Araneidae).

A new species of the orb-weaving spider genus Aculepeira Chamberling & Ivie 1942, A. morenoae new species, is described and illustrated based on male and female specimens from the Argentinean natural flooding pampas grasses.

Redescription of the orb-weaving spider Gasteracantha geminata (Fabricius, 1798) (Araneae, Araneidae).

The orb-weaving spider genus Gasteracantha Sundevall, 1833 (Araneidae) is notable for its pronounced sexual size dimorphism. Gasteracantha females are characterized by having a highly sclerotized "spiny" abdomen varying in relative size and number of spines, as well as abdomen dorsally and ventrally provided with varying numbers of sigillae (Cambridge 1879). The genus currently includes 70 desc...

Two new species of the orb-weaving spider genus Alpaida (Araneae, Araneidae) from Peru.

Two new species of the orb-weaving spider genus Alpaida O. P.-Cambridge, 1889 are described and illustrated; Alpaida losamigos n. sp. based on females from Madre de Dios, and Alpaida penca n. sp. based on females and males from Cajamarca.
