Shape of submarginalis: straight and adjacent to anterior margin of wing in basal half, then dipping before reaching marginalis. Metasoma. L: W of metasoma: 37.0: 43.0, 1.2× as wide as long. Anterior margin of T1: weakly concave medially. Basal foveae on T1: absent. Sculpture of T1: smooth with setigerous punctae. Sculpture of T2: smooth with setigerous punctae; basal foveae absent.

Etymology

This species is named after the outstanding American evolutionary biologist Patricia Adair Gowaty, who exploded the myth of sexual fidelity in many female song birds and demonstrated that A.G. Bateman’s much quoted, classic study on sexual selection in fruit flies was methodologically flawed, making his conclusions untenable. The name is treated as a noun in the genitive case.

Diagnosis

This species is unique in the H. insulare group in having smooth metasoma with setigerous punctae and absence of basal foveae on T1.
