Amblyomma is a genus of the ticks (Ixodidae). It is distributed worldwide, with most of the species occurring in the New World . Certain species cantransmit infectious diseasesas vectors , including Rocky Mountains spotted fever in humans and tularemia , anaplasmosis, and water-borne heart disease in animals.

features

The mouth parts are significantly longer than the part of the Gnathosoma that is close to the body (called "base capituli"), so bites can be more painful than from other ticks. The genus is endowed with eyes. There are ornaments on the chitin shield. This genus does not have additional shields on the anus.

The ticks can get very large. The females of Amblyomma tuberculatum reach up to 25 millimeters. This makes them the largest ticks on the North American continent. The species Amblyomma varium , which lives in South America and feeds on sloths , can grow even larger.

distribution

Numerous species of this genus are known. They can be found in warm regions north and south of the equator on all continents. They can occur in the northern hemisphere up to 40 degrees latitude , in the southern hemisphere they reach 50 degrees south latitude . They also occur within this range on islands far away from the mainland such as the Galápagos Islands and the Antilles . Many endemic forms are found here.

Way of life

The ticks not only parasitize mammals, but can also attack amphibians and reptiles . Amblyomma dissimile affects iguanas and Amblyomma tuberculatum is found on turtles.

Systematics

The genus Amblyomma is the third largest within the family of ticks. The species list is based on Kolonin (2009).
