Dark-legged Artoria Artoria atrata Prado, Baptista & Framenau, 2024

(after Prado et al. 2024): Males of A. atrata are distinguishable by its colour, with a very dark carapace and first two pairs of legs contrasting with the other yellowish-brown pairs of legs. Their palps resemble A. slatyeri and A. howquaensis by their spoon-shaped tegular apophysis and slightly sclerotized basoembolic apophysis with a small and rounded median flap A. atrata may be separated from both species by the basoembolic apophysis smaller and less projected. It resembles A. howquaensis but not A. slatyeri by the tegular apophysis smaller, with its apex directed retrolaterally (vs. apically) and the embolus darker, narrower and filiform (vs. as a mostly translucent ribbon). Males of A. atrata may be set apart from A. howquaensis by the tegular apophysis with smooth curved prolateral margin (vs. with thin, transverse median keel), and distal margin with a median concavity and a rounded blunt distal lobe at the retrolateral corner (vs. convex and with pointed hook). Females of A. atrata resemble A. howquaensis by the general shape of the epigyne, with a small posteriorly placed median septum with a median notch, and internal genitalia, with large, rounded spermathecal organs. In A. atrata the epigyne is mostly formed by a sclerotized plate in which the lateral lobes merge, with median septum placed at the posterior fourth of the epigyne and surpassing the lateral lobes, while in A. howquaensis the epigyne is poorly sclerotized, with lateral lobes not very well-delimited mesally from median septum and surpassing them posteriorly.
