KW - Tegenaria atrica [Opisthosoma / / effect of temperature during embryo KW - temperature during embryo development KW - Temperature effect on opisthosoma anomalies in adult] [Phylogeny / / AB - By exposing embryos of Tegenaria atrica C. L. Koch to alternate temperatures of 12[degree]C and 32[degree]C, structural anomalies were caused in all abdominal metameres of that spider. The changes in the shape of abdomen and the persistence of stump appendages in the prothelar and postthelar zone of the abdomen are considered atavistic characteristics related to the phylogenetic past of Arachnida.
