The female differs by the spermatheca broad at its base, tapering to a single or bifid slender spiraled distal region (Fig. 6). Additionally, females have cephalothorax and legs dark brown or brown, and the abdomen metallic yellowish-green, dorsally with central longitudinal black stripe and a series of five black stripes on both sides, extending laterally (Fig. 26).Male unknown.
The specific nameis derived fromthe Brazilian indigenous Tupi language, meaning “child”. It refers to the local children that found the type specimens high in a tree in Areia, State of Paraíba, Brazil, during an arachnological expedition.
