Key characters
- c2, d2, e2 absent (Figs. 1-2)
- f2 present or absent; when present inserted in lateral position (Fig. 2)
- h2
- not elongate
- many species with short dorsal setae, subequal in length (Figs. 1-5)
- anterior margin of prodorsum with broad flat projection extending over coxae I-II and base of gnathosoma (Figs. 1, 6)
- ventral, genital and anal plates well developed (Figs. 7-9)
- 2 pairs ps setae (Fig. 9)
- 4 segmented palp
- solenidia on tarsus I-II short, rod-like (Fig. 10)
- deutonymphal dorsal setae differ in shape to those of adult (often diagnostically significant)
Similar taxa
Cenopalpus - c2 present; solenidia on tarsi I-II long, slender (Fig. 10); with distinctive ventral plate, delimited by pattern in cuticle
Amblypalpus - no setae in f-series present; ventral and genital plates not developed
Number of species
over 300

Distribution
World wide.
By far the most species are recorded from Neotropical region ~129 spp.), followed by Nearctic (~69 spp.) and Oriental (~49 spp.) regions.
Species rich countries include: China, Greece, Italy, Mexico, Pakistan, USA
Hosts
- usually red, orange, brown in colour when alive (Figs. 11-12)
- often with dark markings dorsally
- eggs red
Colour

Remarks
The dorsal setae of the deutonymphal differ in shape to those of adult and these differences can be of significance for species separation.
