1. Sobre o gênero Chrysometa (Araneae, Tetragnathidae) no sul do Brasil
RESUMO O macho de C. cambara Levi, 1986 é considerado como pertencente à C. itaimba Levi, 1986. A fêmea de Chrysometa aramba Levi, 1986 e o novo macho atribuído à C. cambara Levi, 1986 são descritos pela primeira vez. Registros atualizados de C. aramba, C. cambara, C. itaimba, C. boraceia Levi, 1986 e C. ludibunda (Keyserling, 1893) são apresentados.

2. Chromosomes of Theridiidae spiders (Entelegynae): interspecific karyotype diversity in Argyrodes and diploid number intraspecific variability in Nesticodes rufipes
Theridiidae is a derived family within the Araneoidea clade. In contrast to closely related groups, the 2n(male) = 20+X1X2 with acro/telocentric chromosomes is the most widespread karyotype among the theridiid spiders. In this work, the cytogenetic analysis of Argyrodes elevatus revealed original chromosome features different from those previously registered

3. Tenacidade e investimento em seda em aranhas de teia orbicular / Tenacity and silk investment in orb web spiders
The origin of the most diverse branch of orbweavers, the Araneoidea, coincides with the origin of the viscid silk in the group Orbiculariae. Many hypotheses were proposed to explain the increased diversity in Araneoidea, however none of them explain this phenomena completely. The present work investigates a new hypothesis: the disappearance of the cribellate

4. Modular evolution of egg case silk genes across orb-weaving spider superfamilies
Spider silk proteins (fibroins) are renowned for their extraordinary mechanical properties and biomimetic potential. Despite extensive evolutionary, ecological, and industrial interest in these fibroins, only a fraction of the known silk types have been characterized at the molecular level. Here we report cDNA and genomic sequences of the fibroin TuSp1, whic
