Distribution

Known only from caves in the state of Pará, northern Brazil (Fig. 19).

Natural history

All 767 specimens (34♂, 179♀, 554 immatures) of Carajas paraua sp. n. were collected in 104 caves distributed in rock outcrops covered by canga vegetation (details in Mota et al. 2015[1]) surrounded by the Amazon Forest. This species is restricted to the underground environment of iron caves that exist in canga, in the ore (a rock with more than 60% iron and little or no silica, carbonates, or sulfides) and iron formations (designated for itabirites, ferruginous dolomites, hematitic phyllites, jaspilitos, and hematite) from Flona of Carajás. The specimens were found on the ground, under rocks in aphotic zones with high relative humidity (≥ 98%) and frequently in caves with bat colonies. The tiny size of the fangs of this species seems to indicate that their diet is based on micro invertebrates such as mites, Collembola and Diptera larvae, often found in high abundance in soil areas with bat guano. Carajas paraua sp. n. is a troglobite spider with a distribution restricted to iron caves in target areas of mining and regions of iron formation with high economic interest.
