Diagnosis

The female of Zorascar pasunepomme gen. et sp. nov. is characterized by the epigyne with a median lobe (ML) that is narrow and deeply concave medially and copulatory openings (CO) exposed laterad of median lobe ( Figs 16E , 18A , 19A ).

Etymology

The species name, a noun in apposition, refers to the famous painting of René Magritte depicting an apple, named ‘Ceci n’est pas une pomme’, to which the genitalia appear to be reminiscent.

GENITALIA. Epigyne ( Figs 16E , 18A , 19A–B ) with median lobe (ML) narrow and deeply concave medially (MS), copulatory openings (CO) exposed laterad of ML; lateral lobe (LL) with pair of stout basal, blunt, conical projections (LP); spermathecae dark, comma shaped as in transparency. Endogyne ( Figs 18B–D , 19C–F ): sperm ducts (CD) short, cylindrical, with three twists; spermathecae (S) reniform, with fairly narrow ventral base, and dorsal, roughly semicircular part, provided with few pores; fertilization ducts (FD) short, flattened and slightly curved.

Male

Unknown.

Distribution
