Persistence and variation in microstructural design during the evolution of spider silk. [PDF]
Sci Rep, 2015 The extraordinary mechanical performance of spider dragline silk is explained by its highly ordered microstructure and results from the sequences of its constituent proteins.

Ancient properties of spider silks revealed by the complete gene sequence of the prey-wrapping silk protein (AcSp1). [PDF]
Mol Biol Evol, 2013 Spider silk fibers have impressive mechanical properties and are primarily composed of highly repetitive structural proteins (termed spidroins) encoded by a single gene family.

Sequential origin in the high performance properties of orb spider dragline silk. [PDF]
Sci Rep, 2012 Major ampullate (MA) dragline silk supports spider orb webs, combining strength and extensibility in the toughest biomaterial. MA silk evolved ~376 MYA and identifying how evolutionary changes in proteins influenced silk mechanics is crucial for ...

A New Genus of the Spider Family Caponiidae (Araneae, Haplogynae) from Iran [PDF]
American Museum Novitates, 2009 Abstract A new genus and species, Iraponia scutata, are established for the first members of the Caponiidae to be found in Iran. Males of this new genus, the second known from Asia, are unique in the family in having an extensive ventral abdominal scutum, and in having lost the posterior median pair of spinnerets.

Three new species of Misionella from northern Brazil (Araneae, Haplogynae, Filistatidae). [PDF]
Zookeys, 2016 Three new species of the genus Misionella are described from Brazil: Misionella carajas sp. n. and Misionella aikewara sp. n. from caves in the states of Pará and Tocantins and Misionella pallida sp. n. from natural and synanthropic dry areas in the states of Piauí, Maranhão, Rio Grande do Norte and Bahia.

First description of the male of Thaida chepu Platnick, 1987 (Araneae, Austrochilidae) with micro-computed tomography of the palpal organ. [PDF]
Zookeys, 2013 The male of the austrochilid spider Thaida chepu Platnick, 1987 is described for the first time. We analyzed the internal anatomy of the palpal organ by using micro-computed tomography to investigate the spermophor as well as the muscles and tendons in ...

On the identity of the type species of the genus Telema (Araneae, Telemidae). [PDF]
Zookeys, 2012 Telema tenella Simon, 1882, the type species of genus Telema, is the only species of family Telemidae reported from Europe and all other 39 congeners occur far from it. However, it has never been properly described. In this paper T.

On the First Asian Spiders of the Family Caponiidae (Araneae, Haplogynae), with Notes on the African Genus Diploglena [PDF]
American Museum Novitates, 2008 Abstract A new genus and species, Laoponia saetosa, are established to contain the first members of the family Caponiidae to be discovered in Asia. Only two Old World genera of caponiids have been described, both from Africa; in having only two eyes, the newly collected spiders from Laos resemble southern African Diploglena, rather than the type genus ...

Zoological Science, 2020 The family Sicariidae comprises the genera Hexophthalma, Sicarius and Loxosceles. This latter is subdivided in eight monophyletic groups based on genitalia morphology and molecular analyses: amazonica, gaucho, laeta, and spadicea (South America); reclusa (North America); rufescens (Mediterranean); spinulosa and vonwredei (Africa).

Comparative cytogenetic analysis among filistatid spiders (Araneomorphae: Haplogynae)
Journal of Arachnology, 2017 Abstract The family Filistatidae is considered sister to Synspermiata or sister to Hypochilidae. Cytogenetic knowledge of this family could be useful for understanding the mechanism of chromosome evolution that has occurred within the group. In this work, two filistatid species belonging to distinct subfamilies, Kukulcania hibernalis (Hentz, 1842 ...
