The tick was sent to the State Entomologist for identification. Figure A shows the tick. Figure B shows a close-up of the mouthparts. Figure C shows a close-up of one of the spiracular plates. What is your diagnosis? Based on what criteria? Also, what is the public health importance, if any, of this genus in North America?
