Fig. 8 A–C

Diagnosis

The ventroposterior edge of the gonocoxites, formed by a pair of rounded lobes flanking a shallow emargination, is sinuous (↓ 1, Fig. 8A ); the posteromedial protuberance is small and unmodified (↓ 2, Fig. 8A ). The posterolateral processes of the tegmen have a complicated structuring, including a flat, subtriangular portion pointing ventrolaterally (↓ 3, Fig. 8C ) and a flat, spoon-shaped portion pointing dorsomedially (↓ 4, Fig. 8C ). The elongate gonostylus is markedly wedge-shaped along the apical and medial edges ( Fig. 8B ).

Etymology

The specific epithet refers to Kaikoura, a small coastal town on New Zealand’s South Island, where the holotype specimen was collected.

Material examined
