Describing a new species is common in taxonomy. Describing a new genus — the rank above species, representing an entire lineage — is rare. Describing seven new genera simultaneously, from a single insect family, on one of the most studied archipelagos on Earth, is extraordinary.
Published in Zootaxa, Austin and Rubinoff at the University of Hawai'i described ten new species and seven entirely new genera of Hawaiian leaf-roller moths in the family Tortricidae. The new moths span an improbable range of adaptations: some are brilliantly iridescent, one from Hawai'i Island may be the largest tortricid moth in the world, and at least one has lost the ability to fly. One species, Iliahia pahulu, is critically endangered, known from a single grove of approximately 30 sandalwood trees on Lana'i.
The structural insight is about the relationship between survey effort and taxonomic surprise. Hawai'i is the world's most famous natural laboratory for adaptive radiation — honeycreepers, silverswords, Drosophila. It has been studied intensively for over a century. Finding seven new genera in a single paper means that entire evolutionary lineages — not just species but the branches above them — existed unnoticed throughout that century of study. The moths are not rare in the sense of hiding; they are rare in the sense of being overlooked. The overlooking is selective: charismatic groups get attention, leaf-roller moths do not. The discovery reveals that the depth of Hawaiian radiation extends into groups nobody was looking at, and the unknown fraction of biodiversity scales not with remoteness but with the distribution of taxonomic attention.
