ABDOMEN: inter-scutal membrane rows of small sclerotized platelets absent posteriorly; dorsum soft portions soft pink tegument. Pedicel scutal ridges very weak. Epigastric scutum not protruding, small lateral sclerites present. Postepigastric scutum absent, postepigastric scutum vestigial; replaced by two oblique and elongated stripes surronding posterior spiracles and two medial and rounded platelets close to epigastric furrow. Colulus replaced by three setae. LEGS: Leg spination (only surfaces bearing spines listed, all spines longer than segment width): femora: I p0-0-3; patellae: I v0-2-2; r0-1-1; II p0-1-1; tibiae: I r2-1-1; II r1-1-1; metatarsi: I v1-1-0. Tarsi I to IV superior claws tooth not examined in detail. Trichobothria not examined. GENITALIA: Ventral view: anterior receptaculum with median longitudinal narrow spoon-like sclerite, extending forward from epigastric furrow to booklung covers line; small recurved sclerite at alf lenght of the spoon-like sclerite; large recurved scerite as wide as pedicel diameter close to epigastric furrow; small globular posterior receptaculum behind small half-moon sclerite located close to epigastric furrow.
