Tarsal segmentation

A 1–2 segmented tarsustarsus:
(pl. tarsi) the subdistal leg segment between the tibia and the pretarsus (apotele).
is the norm for most groups of arthropods, but insects commonly have up to 5 tarsal segments (tarsomeres) and several groups of arachnids (whipscorpions, some opilionids) have one or more pairs of tarsitarsus:
(pl. tarsi) the subdistal leg segment between the tibia and the pretarsus (apotele).
highly subdivided. Most mites have 1-segmented tarsitarsus:
(pl. tarsi) the subdistal leg segment between the tibia and the pretarsus (apotele).
, but a few have 2-segments, and rarely (e.g., some Anystidae) highly subdivided tarsitarsus:
(pl. tarsi) the subdistal leg segment between the tibia and the pretarsus (apotele).
