Diagnosis

The male differs from those of Typhochlaena seladonia by shorter and broader embolus (Figs 8–10). Differs from Typhochlaena costae sp. n. by the embolus longer and stouter. The females differ by the strongly curved spermathecae, diverging, in their basal portion (Fig. 11). Additionally, the females have cephalothorax and legs covered with dark setae having a blue metallic sheen under light, abdomen black ventrally and dorsally with a central pinkish stripe having zigzag border (Fig. 24). The males are light brown and the abdomen is black with a dorsally pale stripe similar in shape to that of the female.

Etymology

The specific name refers to the project AMMA – arachnids and myriapods from Brazilian Atlantic rainforest carried out by the arachnologists from Museu Nacional, Rio de Janeiro, who collected the types.
