Titled Blister beetle dermatitis in New Zealand by Christmas TI1, Nicholls D, Holloway BA, Greig D. 

“Seventy-four New Zealand Army personnel with a distinctive bullous dermatosis caused by an endemic beetle are described. These are the first reported cases of this condition in New Zealand. The beetle, Thelyphassa lineata (Fabricius) belonging to the family Oedemeridae was shown to be a vesicant species, as skin contact induced blisters in volunteers. This is a previously unrecognised property of this species.”
