Haemadipsa rjukjuana is a species of terrestrial blood-feeding leach in the family Haemadipsidae (order Arhynchobdellida).[1] They are mostly found in Taiwan, although they have also been confirmed from Gageo Island in South Korea.[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.[3]
A 2011 study found that the species is genetically distinct from Haemadipsa japonica.[4]
Physical description
editHaemadipsa 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.[4]
H. rjukjuana typically grows between 14 and 37 mm long, with a width varying between 2.5 and 5.3 mm.[4]
