Description(s)
Tapanila & Roberts, 2012:
Diagnosos: Xylokrypta durossi is a curved, roughly U-shaped, boring having two widely-spaced, circular cylindrical shafts that connect below the wood surface to a kidney-shaped chamber. All margins of the boring are sharp, cross-cutting the xylem tissues with minor
deformation. The boring penetrates 10–14 mm deep, enough to
maintain a 1–2 mm ‘roof’ of xylem above the chamber.
Melnyk et al., 2020 (for 2021):
Diagnosis/description: Kidney-shaped borings with apertures oriented perpendicular to wood surface.
