Fufius funebris Vellard, 1924 Figs 1-11, 45

Fufius funebris Vellard, 1924: 153; Guadanucci and Indicatti 2004: 256, fig. 7 (redescribed male and female, male misidentified).

Diagnosis.

The male differs from those of all other species in the genus by the characteristic very long embolus having a subtle constriction on its middle (Figs 1-2). The female differs from those of all other species by the spermathecae having spiraled stalks (Fig. 9).

Types.

Syntypes, 3 males and 8 females, should be deposited in Instituto Vital Brazil, Niterói; 1 female, 1 male in the personal collection of Jean Vellard. Types lost ( Guadanucci and Indicatti 2004).

Remarks.

Vellard (1924) described Fufius funebris based on 3 males and 8 females from Catalão, Goiás, Brazil. The types should be deposited in the collection of Instituto Vital Brazil, Niterói, but were not found and considered lost ( Guadanucci and Indicatti 2004). These authors redescribed this species based on a female from the type locality and a male from Brasilia, Distrito Federal, ca. 260 km northwards. However, additional specimens we obtained from type locality, both male and female, and show that the female was correctly identified by Guadanucci and Indicatti (2004), but not the male. Vellard (1924) published a figure showing in detail the Fufius funebris embolus morphology (Fig. 6), which is very long and has a median constriction. An embolus tapering to its tip can be easily distinguished from the Guadanucci and Indicatti (2004) drawings, as shown in their figs 1-3. Conversely,the bulbs of the specimen we obtained from type locality (Figs 1-2) fits very well with the figure of Vellard (1924) (Fig. 6) and can be assigned without doubts to Fufius funebris . The male of the species Guadanucci and Indicatti (2004) attributed to Fufius funebris belongs to a new species, described below as Fufius candango sp. n.
