Diagnosis

The female of Andromma anacardium sp. nov. is characterized by the wide sternum and by the epigyne with copulatory openings surrounded by a dark semicircle.

Etymology

The species name, a noun in apposition, refers to the tree Anacardium occidentale L. as the dark pattern of the epigyne ( Fig. 9C ) resembles two nuts of the cashew tree.
