Dermacentor nitens is a hard tick that, in North America, is limited in distribution to areas of Florida and surrounding areas in the southeastern United States.11 The tick pictured does not have a scutum, as do the hard ticks, so it is an argasid, or soft tick. The prominent spines covering this tick's cuticle allow the tick to be readily identified as Otobius megnini, the spinose ear tick.12
