SUBFAMILY DYNASTINAE

TRIBE CYCLOCEPHALINI

Cyclocephala tridentata (Fabricius) 1801: 170 ( Melolontha ); Paulian 1947a: 68; Chalumeau and Gruner 1977: 587; Chalumeau 1978: 44, 1983a: 149; Endrödi 1985: 99. Distribution. Barbados, Dominica, Guadeloupe, Martinique, St. Lucia ; record Dominican [Domineekan] Republic in Endrödi 1966 is an error. Colombia, Surinam; Lesser Antilles and Latin America .

Chalepus barbatus barbatus (Fabricius) 1787: 10 ( Scarabaeus ); Blackwelder 1944-1957: 253; Paulian 1947a: 73; Endrödi 1966: 403; Chalumeau and Gruner 1977: 590 (suggesting labelling error); Chalumeau 1983a: 216 (doubting Guadeloupe record); Endrödi 1985: 172; Audreau: 2001: 426. Distribution. Barbados, Cuba, Guadeloupe, Hispaniola, Puerto Rico, St. Barthelemy, St. Lucia, St. Martin. Other subspecies are from Guatemala to Argentina. Notes. Apparently introduced to Lesser Antilles.

TRIBE DYNASTINI

Dynastes hercules (Linnaeus) 1758: 345 ( Scarabaeus ); Paulian 1947a: 80; Chalumeau and Gruner 1977: 597; Cartwright and Chalumeau 1978: 21; Chalumeau 1983a: 162; Chalumeau and Reid 2002. Distribution. Dominica and Guadeloupe (type locality) for the nominate subspecies. The subspecies D. h. alcides (Olivier) 1789: 7 (= D. h. reidi Chalumeau 1977: 237; = D baudrii Pinchon 1976 (nomen nudum) occurs on Martinique and St. Lucia . The full range of the species, with nine subspecies, includes these islands and from Mexico to Panama, and throughout northern South America to Bolivia and Brasil ( Chalumeau and Reid 2002; Silvestre 1996); Lesser Antilles and Latin America . Notes. Gruner and Chalumeau (1977) summarize the biology of the species. Adults are attracted to lights, even during nights of full moon; larvae found in decaying trees. Rather common, and the largest beetle species in the Lesser Antilles. The polymorphism in the male horns led to several names being applied to this species.

TRIBE ORYCTINI

Tomarus ebenus (Degeer) 1774: 317 ( Scarabaeus ); Paulian 1947a: 76 ( Ligyrus ); Chalumeau and Gruner 1977: 592; Cartwright and Chalumeau 1978: 26; Chalumeau 1978: 44, 1983a: 156. Distribution. Dominica, Guadeloupe, Hispaniola, Marie-Galante, Martinique, St. Lucia , Saint Martin. Mexico, Colombia, Venezuela, Guyana, Surinam, Brasil; widespread Antilles and Latin America . Notes. Adults attracted to lights; larvae feed on small tubers of Dioscoraceae and Convolvulaceae and may damage gardens.
