| Abstract: | A population of Prorachias bristowei Mello Leitão 1924, a monotypic trapdoor spider, was studied in earthen road banks in southeastern Brazil. We assessed burrow densities, depths and widths, morphometric measures of spider bodies and recorded life history traits. Most burrows belonged to intermediate juveniles, followed by adults and a few juveniles. Egg sacs (mean of 131 eggs) and newly hatched spiderlings received parental care within the maternal burrow. Entrance diameters and burrow depths were significantly correlated with cephalothorax width and length, the length of the first leg and length of chelicera and number of eggs. Food items were Isopoda, Coleoptera, Hymenoptera and Ensifera. The clumped behavior and low dispersal ability can make the spiders vulnerable to anthropogenic modifications of their habitats. |
