case_images: The three mites were identified as O. bursa females based on the following morphological characteristics: tritosternum present, a posteriorly narrowed genitoventral shield, dorsum of body with relatively few setae, elongate, edentate chelicerae, sternal plate wider than long, short, shearlike chelae with well-developed, distinct fixed and movable digits, a teardrop shaped anal plate with anal opening at the anterior end (Figure 2), single holodorsal shield gradually decreasing in width posteriorly; a j6 setal pair shorter, not reaching the bases of following pair and the third pair of setae clearly on posterior corners of sternal shield (Figure 3).
