Morphological aedeagal parameters (H1: height of bent aedegal part, measured from the level when shaft dorsal margin just starting to bend upward (A either shaft dorsal margin straight, e.g. in Oligonychus afrasiaticus or B undulating, e.g. in O. oenotherae Smiley and Baker) to maximum height of knob dorsal margin, H2: height of knob stem, measured from the level when shaft dorsal margin just starting to bend upward to the level of measuring stem width, L1: length of shaft dorsal margin; L2: length of knob, W1: width of shaft, W2: width of knob stem, AL: length of knob anterior projection, PL: length of knob posterior projection, α1: angle formed between shaft axis and knob axis, and, α2: angle formed between shaft axis and bent part axis) that measured and used in the diagnostic keys for differentiation among some Oligonychus species of the subgenus Reckiella.
