history
Mid-Crestacous Kachin Amber is an important resource for the study of variation, evolution, and ecology of microarthropods, including microarthropods, including microarthropods, including arachropods. Its unique preservation offers a unique opportunity to find biological associations between organisms with high loyalty. The whips scorpions (Thyppondaida) are rare in the fossil record, with some known from the period of paleoic period and cetaceous period. However, ecological interologications of other organisms remain unevenly unexplored.
result
Here, we describe a new species in whip scorpion, Mesothelypyphhonus xiaoae SP. Nov., from Kachin Amber. These species are diagnosed by small body size, a surface of the pedipalp coxal appysis, six stomach teeth Sternite III. Especially, fossil includes a heterosigmatic mite (acariforms: prostigmemes: heteroshatmata: trochometridiidae) attached to the first leg of whip scorpion. MITE appears to pick up a large area specified by a foot mainly used for host sensory purposes, which may be more difficult to exclude. This association is likely to represent a chance of phoresy, which mite benefits from transportation and protection provided by whip scorpion.
Finally
Based on modern knowledge of Troops in troops Biology and host association, we suggest that while whip or host host is likely to be a nesting-nesting Apoidea (bees or Wases). This hypothesis means mid-cretaceous ecosystems include early trails that show nesting behaviors, which gives an important goodness for the development of old symbol.
