Explanation of Names
Lagoa Harris, 1841 was treated as a synonym of Megalopyge in Neumoegen & Dyar (1894). This synonymy was reversed and then reapplied several times since. Dyar (1903) & (1910) treated Lagoa as a valid species. Forbes (1923) and Hopp in Seitz (1934) followed the synonymy. McDunnough (1937) recognized Lagoa as did Davis in the Hodges 1983 Checkist (1). Becker (1995) (2), Epstein & Becker (1995) (3) and Epstein (1996) (4) placed Lagoa back as a synonym of Megalopyge, having found no reason for overturning the synonymy. Pohl et al. (2016) (5) followed Becker (1995). - paraphrased from comments by Marc Epstein 5/15/2018
Numbers lists seven species for North America, including some that were formerly assigned to the genus Lagoa.
