Fufius candango sp. n. Figs 16-26, 45

Fufius funebris : Guadanucci and Indicatti 2004: 256, figs 1-6 (male, misidentified).

Diagnosis.

Male and female differ from those of all other species by presence of preening comb on retrolateral tip of metatarsus IV formed by small spines (Fig. 24).

Etymology.

The specific name, candango, refers to the workers who were largely responsible for building Brazil’s capital, Brasilia, where the type specimens of the new species were collected.

Remarks.

The male of this species was erroneously attributed to Fufius funebris Vellard (1924) by Guadanucci and Indicatti (2004). See discussion for Fufius funebris above.
