Unlike the other taxa, where specimens were frozen alive, these specimens died during transport and were frozen upon arrival. Likely due to their untimely demise, tracheae suffered from fluid infilling before scanning, resulting in obscured morphology. Several specimens were scanned, and the best example was chosen for inclusion here. Zoraptera are an excellent candidate for further micro-CT study of better-preserved specimens. DESCRIPTION: HEAD: H-DCT and H-VCT in close contact, proceeding anteriad. H-Ant off H-DCT, no other head tracheae visible in this scan. THORAX: T2-S with several branches visible on specimen right side but only two determinable: T2-VB and T2-CT. T2-VB ventrad; T2-VC present. T3-S visible with T3-DLT extending dorsad and posteriorly to link with A1-S. Other thoracic tracheae partial, determined from examining volume cross sections to establish position in the body. ABDOMEN: A1..7-S discernible.
