Brachypylina is a group of oribatid mites, variously listed as a suborder,[1] infraorder,[2][3] or a cohort.[3][4]
Brachypylina are 0.15 to 2.0 mm or more in length, beetle-like, usually tan to dark brown, and covered in armour. Some have pteromorphs (wing-like flaps possessed by some oribatids). The notogastral shield is separated from the prodorsal and ventral shields by a line of dehiscence (circumgastric furrow). There is usually a pair of trichobothria on the prodorsum. There are 3 (rarely seemingly 2) pairs of genital papillae. The subcapitulum is often diarthric, and sometimes has a mental tectum or is suctorial.[4]
Females have a well-developed ovipositor. Males are usually half the mass of females with a smaller genital opening, and they have a spermatophoric organ instead of an ovipositor.[4]
