1 Adult data are based on all studied species and populations, including C. monilipes from Sweden, Germany and Spain. Ontogenetic data are from C. arboricolus n. sp. (topotypical population), C. retractus (near-topotypical population), a species in the ‘retractus group’ (New York population; see text), and C. monilipes (Norwegian population; see Seniczak and Seniczak 2019 and corrections in R12); from each population all instars were studied, except no larva was available from the C. retractus near-topotypical population.
2 Setae (Roman letters) and solenidia (σ, φ, ω) are shown where they are first added and are assumed present through the rest of ontogeny, unless noted in brackets. Setae in parentheses represent pseudosymmetrical pairs; dash indicates no addition; underline indicates solenidion is coupled to seta d, in same alveolus.
3 Seta l' of tibia III is invariably deutonymphal in C. arboricolus, C. retractus and the ‘retractus group’ from New York. By contrast, in C. monilipes l' first forms along with v" in the tritonymph, according to Seniczak and Seniczak (2019); appropriately, l' is absent from both tibiae III of our single deutonymph from Sweden.
