Etymology

This species is named after Sarah Blaffer Hrdy, the trailblazing primatologist and theoretical biologist whose early studies on the reproductive strategies of langurs in Mount Abu, Western India, propelled her to study the pivotal role that the rearing of children by ‘mothers and others’ has played in shaping the evolution of our own species. The name is treated as a noun in the genitive case.

Diagnosis

Hadronotus hrdyae sp. n. is unique in having an incurved stigmalis on the fore wing.
