Fig. 9 A–C

Diagnosis

The gonostylar base in G. nativitas sp. nov. is broader than in any other species of Glemparon (↓ 1, Fig. 9B ). The setae on the ventral gonocoxal surface form a cross-shape ( Fig. 9A ); the medial bridges are densely microtrichose (↓ 2, Fig. 9A ); and the posteromedial protuberance has a T-shaped, sclerotized process that projects ventrally (↓ 3, Fig. 9A ). The tegminal processes have a serrate posterior edge, with the largest sawteeth situated ventrally (↓ 4, Fig. 9C ).

Etymology

The specific epithet is a Latin noun in apposition meaning Christmas, an allusion to Christmas Village Hut on Stewart Island, the type locality.
