Heliolites is a large and heterogenous [2] genus of extinct tabulate corals in the family Heliolitidae. [3] Specimens have been found in Ordovician [4] to Devonian [5] beds in North America, [6] Europe, [5] Africa, [7] Asia, [8] and Australia. [4] The genus is particularly abundant in the Wellin Member of the Hanonet Formation of Belgium. [9]

Members of the genus are distinguished by a prominent tubular coenenchyme (the tissue linking neighboring polyps) with 14–17 tubules around each corallite (the stony cup in which each polyp sits.) [10]
