It was first described in 2001 by Tamás Szűts and Rudy Jocqué based on a holotype found near Appouasso and is named after the Latin for showing off, after the iridescent colours of the legs.

The male has a distinctive pattern of spots on the tegulum, which has two prongs, and a long embolus that curves so far that it loops around itself.

The female can be distinguished by its epigyne, particularly the large triangular plate and the long coiled copulatory ducts.

[2] The genus is named in honour of the Portuguese arachnologist Amélia Vaz Duarte Bacelar.

[3] The species is named after the Latin word iactare, which can be translated showing off, and refers to the distinctive copulatory organs and the iridescent colouring visible on the legs.

[4] In 2008, the genus was allocated to a clade named the Bacelarella group based on DNA sequencing.

The palpal bulb has a tegulum with a pattern of spots, from which springs a long embolus that curves over so that it circles round over 360 degrees.
