Bothriocroton concolor, commonly known as the echidna tick, is a hard-bodied tick species endemic to Australia.[1]
They are found across coastal and subcoastal Australia, from Northern Queensland to Kangaroo Island.
As the name suggests, B. concolor has strict host specificity to echidnas, specifically the short-beaked echidna, Tachyglossus aculeatus. The exception is on Kangaroo Island, where B. concolor can be found on Macropus fuliginosus fuliginosus, the Kangaroo Island subspecies of the Western grey kangaroo.[2]
Description
Bothriocroton concolor, like all Bothriocroton, tend to be large, rounded ticks. They are distinguishable by the presence of a conspicuous pointed spur projecting medially from distoventral palpal segment II.[3]
Vector transmission
Bothriocroton concolor can host Borrelia tachyglossi, a bacterium related to, but distinct from Lyme disease and relapsing fever Borrelia. It is not known to be pathogenic to humans or other animals.[4] A Rickettsia bellii sequence of unknown pathogenicity has been previously identified in three B. concolor.[5][6]
