Abbreviations The abbreviations are grouped according to the major body subdivisions and are arranged al- phabetically within each section. The body of a damaeid mite consists of two main regions, an anterior propodosoma, which contains the head structures, and a posterior hysterosoma or abdo- men. These are separated by the sejugal groove. The dorsal part of the propodosoma, which in- cludes all structures located dorsally to the leg insertions, is called the prodorsum. The anterior part of the prodorsum, the rostrum, surrounds a cavity, the camerostome, in which a pair of chelicerae and a pair of pedipalps are located. The ventral border of this cavity is formed by the postero-laterally hinged infracapitulum. Together these five structures form the mite mouthparts or gnathosoma. Epimeres I and II are the lateral and ventral part of the propodosoma located between and below the leg insertions. Each epimere is as- sociated with a 5-segmented leg consisting of trochanter, femur, genu, tibia and a distal tarsus with single claw. The notogaster is the dome-like shield which in the adult dorsally covers most of the hysterosoma. It is separated from the ventral part of the hysterosoma by a groove, the circum- gastric scissure. Ventrally to this one finds the epimeres of legs III and IV, and posterior to these the genital and anal regions.
