Haemadipsa rjukjuana

Haemadipsa rjukjuana is a species of terrestrial blood-feeding leach in the family Haemadipsidae (order Arhynchobdellida).

[2][3] Several pathogens have been reported from the leech, specifically Anaplasma, Bartonella, Borrelia, Ehrlichia, Rickettsia, and Wolbachia.

Haemadipsa rjukjuana was the first leech recorded to carry a Bartonella species.

[4] Haemadipsa rjukjuana is distinctive for its colourations on its back, having black splotches over a reddish, yellowish, or greyish background.

Another distinguishing feature of its colouration is its thoroughly black underside and the lack of a clear median stripe on its back.
