Dorsum with five large plates: a large anteromedial plate, a larger posteromedial plate, a pair of lateral anterior and posterior plates of similar size and a larger pair of medial lateral plates. A pair of tiny platelets, barely more than sclerotized glandularia are located behind the posterior lateral plates. Anteromedial dorsal plate 186 long, posteromedial dorsal plate 251 long. Tips of first coxae extending well beyond anterior idiosoma margin. Coxoglandularia 4 lying on posterior suture line of fourth coxae. Gonopore 106 long. Genital field with 11 pairs of acetabula, the two anterior pairs noticeably larger than posterior pairs. A pair of glandularia flanking the genital field. Length of P1–5: 28, 60, 50, 96, 36. P-2 with a rectangular anteroventral extension. Ventral margin of P-4 with one stout and one thin seta. Length of I-leg-4–6: 88, 96, 100 (to tip of segment).
