Extreme degree of chromosome number variability in species of the spider genus Scytodes (Araneae, Haplogynae, Scytodidae)
(Wiley-Blackwell, 2008-05-01)
Genus Scytodes includes most species of the spider family Scytodidae. Until now, 187 species of the genus have been described. In spite of this great diversity, only three Scytodes species were karyotyped so far. The present ...

Chromosomal data of two pholcids (Araneae, Haplogynae): A new diploid number and the first cytogenetical record for the New World Clade
(Amer Arachnological Soc, 2005-01-01)
Mesobolivar luteus (Keyserling 1891) and Micropholcus fauroli (Simon 1887) specimens were collected in Ubatuba and Rio Claro, both in the state of São Paulo, Brazil. Mesabolivar luteus showed 2n (male) = 15 = 14 + X and ...
Comparative cytogenetic analysis among filistatid spiders (Araneomorphae: Haplogynae)
(2017-04-01)
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 ...

Phylogeny of Sicariidae spiders (Araneae: Haplogynae), with a monograph on Neotropical Sicarius
(Oxford University Press, 2017-03)
Sicariids are an infamous spider family containing two genera: the poorly known Sicarius Walckenaer and the medically important Loxosceles Heineken & Lowe. We present the first broad survey of the morphology of the family ...
Venomous Loxosceles Species (Araneae, Haplogynae, Sicariidae) from Brazil: 2nâ™ = 23 and X1X2Y Sex Chromosome System as Shared Characteristics
(2020-04-06)
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 ...
Evolução cromossômica em aranhas caranguejeiras (Mygalomorphae) e Haploginas Basais (Araneomorphae)
(Universidade Estadual Paulista (Unesp), 2013-04-26)
As espécies de aranhas pertencentes aos grupos Mygalomorphae e Haplogynae (Araneomorphae) exibem uma grande diversidade cariotípica, isto é, 2n=14 a 2n=110 e sistemas cromossômicos sexuais (SCS) dos tipos X0, XY, X1X20 e ...
