Researchers examined the distinct pattern of spots and six darker and lighter transverse stripes, divided by a light stripe in the center, on the abdomen of these spiders.
The upper body of Trichopelma grande is covered with dense chestnut-brown hairs along the edges, while the center remains smooth and hairless, showcasing a dark brown surface. The size of the head of the discovered spider significantly exceeds that of other known species within the genus.
