A novel fluid-feeding mechanism for microbivory in the Acariformes (Arachnida: Acari)

摘要: Low temperature scanning electron microscopy (LT-SEM) has revealed anatomical details suggesting that Osperalycus and Gordialycus (Acariformes: Nematalycidae) have an unusual feeding apparatus is hypothesized to be specialized for on the fluid contents of small microorganisms (diameter<5 μm). Both mite genera a strategy appears involve picking up placing them onto subcapitulum puncturing. However, they slightly different variants same basic rupturing mechanism. Whereas evolved expansive convergent rutella hold in place while pushing chelicerae into them, pouch which microorganism inserted. The reinforce this break microorganism. types mouthpart seem adapted minimize waste, appropriate specialization given organically impoverished habitats these mites live.
