Oribatella and Tectoribates (Oribatellidae)

A notogaster with 10 pairs of setae (O1) and with porose areas (O5a) is regarded as characteristic for the stem species of Oribatellidae . Whereas Oribatella and other genera have porose areas (O5a) without known exceptions, Tectoribates shows notogastral saccules instead (O5), a further case of regressive plesiomorphic (figure 7). The same is presumed for the unique species within the genus, Oribatella bromeliarum , with 15 pairs of notogastral setae (O1) (cf. section on ’opisthonotal and humeral characters’).
