Female palp claws absent; spines absent; tarsus unmodified, patella without prolateral row of ridges. ABDOMEN: Book lung covers elongated, about 3x longer than wide, rather pear- or dumbell-shaped. Pedicel dorsal part of epigastric scutum with subterminal ridge, scuto-pedicel region with slightly modified hair bases (appearing as small denticles). Dorsal scutum surface smooth but hairbases on dorsal scutum pit-like, causing a punctate impression. Epigastric scutum without lateral joints, posterolateral part with row of longitudinal ridges. Postepigastric scutum not fused to epigastric scutum. LEGS: tibia IV specialized hairs on ventral apex present, femora in dorsal view: Femur IV recurved, Femora I-II procurved, Femur III straight, tibiae special hairs on ventral apex of tibia III & IV thin, plumose, distally flattened, with fringed lateral margins and spatulate tips, metatarsi special hairs on ventral apex of metatarsi III & IV short, dagger-like, with finely serrated ridges on surface and coarsely serrated lateral margins; dorsal apex of metatarsi I-IV with small, shieldlike appendage. Leg spines absent. Tarsi I to IV superior claws tooth not examined in detail. Trichobothria examined with Compound microscope. GENITALIA: Dorsal view: thoma et al. (2014): "Dorsal view (Figs. 8FG): receptaculum (re) oval, containing an oval sac-like structure (sa), laterally framed by long, posteriorly pointed sclerites (apodemes; lap); globular appendix (gap) lying dorsally of receptaculum about 1/3 as long as receptaculum; posterior part of receptaculum dorsally covered with papillae (pap); a transverse sclerite (tsc) lies anteriorly to the receptaculum and bears medially a nail-like structure (na).".
