Asian longhorned tick, (AKA, East Asian, Scrub or Bush Tick)
Newly Discovered Invasive Tick in the United States
Species:
Haemaphysalis longicornis Neumann
Description:
Adult ticks in this Genus are relatively small (easily overlooked), inornate ticks with overall light-to-dark brown coloration. Shape of the female scutum is rounded. They are without eyes. The basis capituli is rectangular, and the head region is “bell shaped” due to the wide expansion of the palps, especially palp article 2. The anal groove is behind the anus. At the species level, H. longicornus has a 5:5 apical hypostomal dentition, and with palp article 3 each possessing an elevated dorso-median spur (suggesting the appearance of a pair of “horns”) and a ventral spur that is broadly triangular in the male, and more acutely pointed in the female.
