Idiosoma rounded, dorsally highly domed, marginal and dorsal shield fused. All of dorsal setae setiform, with smooth or pilose distal margins. Number of sternal setae four pairs in females (St2 lacking) and five pairs in males; number of ventral setae four or five pairs. Ventral shield with a large and deep cavity; three to four pairs of long needle-like ventral setae can be seen on the lateral margins of this cavity. Genital shield of female linguliform or scutiform, with posterior margin situated between coxae IV. Adanal and postanal setae absent. Genital shield of male circular and placed between coxae III or IV. Peritreme hook-form or R-shaped. Tritosternum with narrow basis, its lacinia with two or three branches. Hypostomal setae are as follows: h1 smooth, long and needle-like, h2 smooth and three or four times shorter than h1, h3 serrate marginally and two times shorter than h1, h4 serrate marginally and three or four times shorter than h1. Palp trochanter of the male bears robust and serrated setae. Corniculi horn-like, digitus fixus of the chelicerae longer than digitus mobilis, chelicerae without internal sclerotized nodes. All legs with a pair of ambulacral claws and with smooth simple setae.
Etymology
The name of the new genus refers to the cavity (depressum) and to its similarity to Rotundabaloghia Hirschmann, 1975 mites. Gender: female.
