- Carapa guianensis (andiroba, crabwood): Amazon Region, Central America, Caribbean
- Carapa megistocarpa (tangare): Ecuador
- Carapa procera (African crabwood, kowi, okoto): West Africa, the Congos

Uses
The timber is important, and oil is produced from the seeds. The name andiroba is from Nheengatu nhandi rob, meaning "bitter oil". Carapa guianensis produces oil similar[clarification needed] to neem oil.
The oil contained in the almond andiroba is light yellow and extremely bitter. When subjected to a temperature below 25 °C, it solidifies producing a consistency like that of petroleum jelly. The oil contains olein, palmitine and glycerin.[citation needed]
Andiroba oil is one of the most commonly sold medicinal oils in the Amazon.[citation needed] It is also used to repel mosquitoes by forming an oilseed cake into balls and burned, or mixed with annatto (Bixa orellana) and formed into a paste applied topically to protect the body from mosquito bites.[5]
Andiroba oil is extracted from light brown seeds collected from beaches and rivers, where they float after being shed by the trees or from the forest ground.
