Chilum absent. Eyes six, well developed, ALE largest, ALE oval, PME circular, PLE oval; posterior eye row straight from above, procurved from front; ALE separated by more than their diameter, ALE-PLE separated by less than ALE radius, PME separated by less than their radius, PLE-PME separated by more than PME diameter. Sternum longer than wide, orange-brown, uniform, not fused to carapace, median concavity absent, without radial furrows between coxae I-II, II-III, III-IV, radial furrow opposite coxae III absent, surface rugose, without pits, microsculpture everywhere but front, sickle-shaped structures absent, anterior margin with interrupted transverse groove, posterior margin extending posteriorly beyond anterior edges of coxae IV as single extension, lateral margin with infra-coxal grooves and anterior and posterior openings, distance between coxae approximately equal, extensions of pre-coxal triangles absent, lateral margins with indented extensions between coxae, without posterior hump, ventral pedicel sclerite not fused to sternum; setae sparse, dark, needle-like, densest laterally, originating from surface. Mouthparts: Chelicerae, endites and labium orange-brown. Chelicerae straight, anterior face unmodified; without teeth on both promargin and retromargin; fangs directed medially, shape normal, without prominent basal process, tip unmodified; setae dark, needle-like, evenly scattered; paturon inner margin with short inter-digitating setae, distal region abruptly narrowed, posterior surface unmodified, promargin unmodified, inner margin unmodified, laminate groove absent. Labium triangular, fused to sternum, anterior margin indented at middle; with 6 or more setae on anterior margin, subdistal portion with unmodified setae. Endites distally not excavated, serrula present in single row, anteromedian tip unmodified, posteromedian part unmodified. Female palp claws absent; spines absent; tarsus unmodified, patella without prolateral row of ridges. ABDOMEN: constricted in middle, without long posterior extension, rounded posteriorly, inter-scutal membrane rows of small sclerotized platelets absent posteriorly; dorsum soft portions white, with dark gray markings outlining anterior pair of paramedian white spots, followed posteriorly by lateral pair of white spots, white circle with gray interior, and sharply delimited posterior, transverse white stripe. Book lung covers large, ovoid, without setae, anterolateral edge unmodified. Posterior spiracles connected by groove. Pedicel tube short, unmodified, 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 absent. Epigastric scutum weakly sclerotized, surrounding pedicel, not protruding, small lateral sclerites absent, without lateral joints. Postepigastric scutum weakly sclerotized, yellow-brown, short, only around epigastric furrow, not fused to epigastric scutum, anterior margin unmodified, with short posteriorly directed lateral apodemes. Spinneret scutum present, incomplete ring. Dorsum setae present, dark, needle-like. Epigastric area setae uniform, dark, needle-like. Postepigastric area setae present, dark, needle-like. Spinneret scutum with fringe of long setae. Dense patch of setae anterior to spinnerets absent. Colulus absent.
