Which type of cyclonic weather system forms in the tropics?

Cyclonic systems that form in warm tropical waters are tropical cyclones. The tropics are roughly within 23.5 degrees of the equator, where strong daytime heating and low vertical wind shear encourage organized convection and a closed low-pressure circulation. Extratropical cyclones develop from temperature contrasts and fronts in higher latitudes, not from tropical convection. Sub-tropical cyclones form in transitional zones, combining tropical and extratropical characteristics, while anticyclones are high-pressure systems with no cyclone-like rotation. So, the system that forms in the tropics is tropical.
