Etymology.

The specific epithet is a Persian feminine name meaning "queen of fire". Noun in apposition.

Diagnosis.

The new species has an abdominal pattern similar to that of A. parysatis sp. nov. (dark abdomen with posterior median white stripe; less distinct in males) but differs by having a dark pars cephalica (vs. pale). The male palps of the two species differ by the RTA being thin and more than twice as long as the tibia in A. atrisa sp. nov. (vs. broad and as long as the tibia). Judging by the shape of the male palp, A. atrisa sp. nov. is probably closely related to A. sorani sp. nov., as both have a long RTA, a similarly shaped median apophysis, a posterior tegular process and an embolus with an anterior process. The two species differ by the shape of the embolic process (Ep), wider than the embolus and gently bent at the tip in A. atrisa sp. nov. (vs. spine-like). The epigyne of A. atrisa sp. nov. is most similar to that of A. parysatis sp. nov. in having a small anterior hood and a thin furrow between the lateral lobes but differs by the furrow being shorter than the bursa copulatrix (vs. the same length as bursa).
