Gelae
''Gelae'' (pronounced /'dʒɛlɪ/) is a genus of round fungus beetles belonging to the family Leiodidae. The beetles are found in different parts of Central and North America. They are small and rounded, feeding on slime moulds. They were originally placed in the genus ''Agathidium'' following the discovery of the first species, ''G. cognatum'', in 1878. The taxonomic position was revised with description of new species in 2004 by American entomologists Kelly B. Miller and Quentin D. Wheeler. Upon creation of the new genus, the five new species are ''Gelae baen'' (sounding like "jelly bean"), ''G. balae'' ("jelly belly"), ''G. donut'' ("jelly doughnut"), ''G. fish'' ("jelly fish"), and ''G. rol'' ("jelly roll"). ==Discovery and taxonomy==
The first species of ''Gelae'' discovered was ''Agathidium cognatum'' (now ''Gelae cognatum''). John Lawrence LeConte discovered the only specimen at Marquette, Michigan, near Lake Superior, in 1878.〔 Another specimen was found by Andrew Matthews in 1887 from the mountains of Totonicapán in Guatemala, and placed it under the then known genus ''Agathidium''. Henry Clinton Fall collected the third species in 1934 from Sugar Pine, California, US. In 1998, Stewart Blaine Peck, Pedro Gnaspini and Alfred F. Newton Jr. reported the occurrence of closely related but distinct species from their extensive cataloguing of round fungus beetles. They noted that the species had unique features different from ''Agathidium'' and other beetles, and labelled them under "Undescribed Genus 7". With reexamination of the tribe Agathidiini to which they belong, they were reclassified under a new genus ''Gelae'' in 2004. Kelly B. Miller and Quentin D. Wheeler described their significant characters and regrouped them, along with five new species, ''G. baen'', ''G. balae'', ''G. donut'', ''G. fish'', and ''G. rol''. They derived the name from a Latin word ''gelatus'', which means "congealed" or "jellied", and to be pronounced like the English word "jelly". This refers to the slime moulds in which they were found. The species names are merely wordplays without any taxonomical jargon, and are simply "whimsical arrangement of letters", as the authors noted.〔
