Sternum as long as wide, pale orange, uniform, not fused to carapace, median concavity present, a small concave pit in posterior half of sternum, without radial furrows between coxae I-II, II-III, III-IV, radial furrow opposite coxae III absent, surface smooth, without pits, microsculpture absent, sickle-shaped structures absent, anterior margin unmodified, posterior margin not extending posteriorly of coxae IV, anterior corner unmodified, lateral margin without infra-coxal grooves, distance between coxae approximately equal, extensions of pre-coxal triangles absent, lateral margins unmodified, without posterior hump, with oval median concavity covering 2/3 of sternum length and 2/3 of sternum width, situated in posterior half, covered with field of clavate setae; setae sparse, light, needle-like, densest laterally, originating from small pits, without hair tufts. Mouthparts: Chelicerae, endites and labium red-brown. Chelicerae straight, anterior face unmodified; without teeth on both promargin and retromargin; fangs without tooth-like projections, directed medially, shape normal, without prominent basal process, tip distally widened; setae light, needle-like, densest medially; paturon distal region unmodified, posterior surface unmodified, promargin unmodified, inner margin unmodified, laminate groove absent. Labium rectangular, not fused to sternum, anterior margin not indented at middle, much more heavily sclerotized than sternum; with 1 or 2 setae on anterior margin, subdistal portion with unmodified setae. Endites distally not excavated, serrula present in single row, anteromedian tip with one strong, tooth-like projection, posteromedian part unmodified, much more heavily sclerotized than sternum. ABDOMEN: cylindrical, without long posterior extension, rounded posteriorly, inter-scutal membrane rows of small sclerotized platelets absent posteriorly; dorsum soft portions red-brown, without color pattern. Book lung covers large, ovoid, without setae, anterolateral edge unmodified. Posterior spiracles connected by groove. Pedicel tube short, ribbed, scuto-pedicel region unmodified, scutum not extending far dorsal of pedicel, plumose hairs absent, matted setae on anterior ventral abdomen in pedicel area absent, cuticular outgrowths near pedicel absent. Dorsal scutum weakly sclerotized, red-brown, without color pattern, covering full length of abdomen, no soft tissue visible from above, not fused to epigastric scutum, middle surface smooth, sides smooth, anterior half without projecting denticles. Epigastric scutum weakly sclerotized, surrounding pedicel, strongly protruding, small lateral sclerites absent. Postepigastric scutum weakly sclerotized, red-brown, long, almost rectangular, covering nearly full length of abdominal length, fused to epigastric scutum, anterior margin unmodified, with long posteriorly directed lateral apodemes. Spinneret scutum present, incomplete ring. Dorsum setae present, light, needle-like. Epigastric area setae uniform, light, needle-like. Postepigastric area setae present, light, needle-like.
