Descriptions and remarks
Macroboring; substrate xylic; tracemaker invertebrate
Emended diagnosis.—Elongate borings in xylic substrata and associated resins, nearly circular in cross section, with an approximately constant diameter. Borings are straight to sinuous or contorted and intertwined and predominantly occur parallel to the fibers of xylic substrata (modified from Donovan, 2018; Mayoral et al., 2020).
Revised diagnosis: Apectoichnus predominantly parallel to the grain or fibres in a xylic substrate, length/width ratio greater than 5. Sinuous to contort.
