Cayenne tick

A member of the Amblyomma cajennense species complex occurring from southern North America through Central America into northern South America.

Uses livestock, horses, wildlife and other mammals as hosts and can be important where animals and people share tick habitat.

Recorded from Mexico through Central America and into northern South America. Records published under the older broad Amblyomma cajennense concept require taxonomic review.

Species-level confirmation should use authoritative morphological keys and, where necessary, expert or molecular examination. Photographs, host and location alone may be insufficient.

Identification requires the complete combination of family, genus and species-level morphological characters.

Use authoritative comparative keys; do not rely on colour, size, host or geography as a single diagnostic feature.

Photographs alone cannot always confirm this species.

Adult males and females differ in dorsal shield coverage, body proportions and feeding-related expansion; confirm stage and sex with an appropriate species key.

Egg, larva, nymph and adult stages are present; host-use pattern is species-specific.

Seasonal activity varies geographically and should be interpreted from local surveillance.

Human biting is documented. It is associated with spotted-fever-group rickettsiae, but organism detection, proven transmission and regional disease risk are distinct evidence categories.

Human biting is documented. It is associated with spotted-fever-group rickettsiae, but organism detection, proven transmission and regional disease risk are distinct evidence categories.

Human-health relevance is stated only where governed evidence supports human biting or transmission; otherwise no human-vector claim is made.

Livestock and horses in endemic areas may support adult ticks, so animal inspection and locally appropriate veterinary control help reduce infestation and human exposure.

Use habitat-appropriate tick avoidance, animal inspection and veterinary-led control.

Remove attached ticks promptly using evidence-based guidance and seek medical or veterinary advice when indicated.
