Diagnosis. Epistome with three anterior extensions, the anteromedial extension aciculate, spatulate or lanceolate, smooth or serrate, usually longer than the others. Dorsal shield entire, fused anteriorly with peritrematic shields and posteriorly with ventri-anal shield. Pre-sternal area with 0–3 pre-sternal shields. Sternal shield bearing four pairs of setae, totally fused to metasternal and endopodal shields; extending posterolaterally around genital shield. Genital shield with convex anterior margin, truncate posteriorly, bearing one pair of setae. Peritrematic shield fused to metapodal and exopodal shield near coxa IV. Exopodal shields in two pairs – a small subtriangular pair between coxae I–II (not always clearly distinct) and a large elongated pair reaching from midlevel of coxa II to midlevel of coxa IV, the latter shield separated from the peritrematic shield by a strip of unsclerotised cuticle.
