Rubroscirus

Gnathosoma. Pedipalps 5-segmented and reach beyond the subcapitulum by at most the distal half of the tibiae. An apophysis on the telofemora present. Stout spine-like seta on the genua and tibiotarsi setae present or absent. Tibiotarsi end in a strong claw. Subcapitulum with 6 pairs of setae: 2 pairs of adoral setae and 4 pairs of subcapitular setae (hg1–4). Subcapitulum is reticulated. Idiosoma, dorsal. Proterosoma bears a shield, complemented with 2 pairs of setose sensillae (at and pt) and 2 pairs of setae (lps and mps). Sensillae at and pt not as densely pilose as in Allocunaxa, Cunaxatricha, and Riscus. Proterosomal shield reticulated. Hysterosomal shield absent in females. Lateral platelets (as in Armascirus and Dactyloscirus) absent. Setae c1–h1, and c2 present. Cupule im present laterad and caudally of e1. Integument not bearing the l shield striated. Striations papillated, not smooth or lobed as in Cunaxa. Idiosoma, ventral. Coxae I–II may be fused; coxae III–IV may be fused. Coxae II–IV setal formula 1-3-1. Genital plates each bear 4 setae; 2 pairs of genital papillae visible underneath the plates. Anal plates bear 1 pair of setae (ps1). 1 pair of setae (h2) associated with, but do not occur on, the anal plates. Cupule ih present in close proximity to h2. Integument between plates striated and bears up to 7 pairs of additional setae. Legs. Tarsi long and slender, and constricted distally but tarsal lobes small and not conspicuous as in Armascirus and Dactyloscirus. A trichobothrium on tibia IV present. Ambulacral claws either side of a 4-rayed empodium present.
