This pattern of extreme phenotypic divergence but limited genetic divergence matches that in some other island radiations. For example, the plant genus Bidens (Asteraceae) shows more morphological diversity among the 19 species in Hawai’i than it does throughout the entirety of the Americas, and yet the total genetic diversity in Hawai’i is comparable to that found within individual species of mainland Bidens (Helenurm & Ganders, 1985). The St Helena Peaks Bembidion appears to have undergone a classical adaptive radiation (Schluter, 2000; Gavrilets & Losos, 2009). The ecological opportunity provided by arrival on a depauperate island with few small predators, and perhaps none	en	Maddison, David R, Sproul, John S, Mendel, Howard (2020): Origin and adaptive radiation of the exceptional and threatened bembidiine beetle fauna of St Helena (Coleoptera: Carabidae).
