Dorsal shield divided into podonotal and opisthonotal sections, each shield with neotrichy more or less extensive, marginal dorsal setae of r–R series with strong neotrichy, inserted on tubercles; with four pairs of pore-like structures (glands) in each part of the shield. Tritosternum bifurcate. Presternal (jugular) platelets with pair of St1 setae. First sternal platelet entire or divided into two, with pair of St2 setae; second pair of sternal platelets with pairs of setae St3, St4. Genital shield irregularly-shaped; with genital setae St5.
