Figure 1 in What is a 'strong' synapomorphy? Redescriptions of Murray's type species and descriptions of new taxa challenge the systematics of Hypsibiidae (Eutardigrada: Parachela)

Figure 1. Schematic depiction of six types of cuticular pedal bars and other leg structures found in the Hypsibiidae. Note that the edges of convex pulvini may overlap with fully sclerotized cuticular bars but are generally faint and weakly defined when observed under light microscopy. Historically, these edges of pulvini were sometimes described as 'bars' [e.g. see Dastych (1988) for Adropion belgicae or Gąsiorek et al. (2016) for Mesocrista].
