Etymology

This species is named after Jeanne Altmann, whose seminal paper in the 1970s laid the groundwork for the conduct of field studies of animal behaviour and who, studying baboons, was among the early primatologists to make females rather than males the focus of animal behaviour studies. The name is treated as a noun in the genitive case.

Diagnosis

Hadronotus altmannae sp. n. is similar to H. wintes but differs from it in the following character states: In H. altmannae sp. n. submarginalis is basally closer to and distally distant from anterior margin of fore wing, and posterior margins of T2–T4 are distinctly raised, whereas in H. wintes submarginalis is distant from anterior margin of fore wing the entire length, and posterior margins of T2–T4 are not raised.
