Coleoscirus

Gnathosoma. Pedipalps 5-segmented; basifemora and telofemora fused but retain a dark line which indicates the presence of the joint. Pedipalps extend beyond the subcapitulum by at most the apical half of the tibiotarsi. Pedipalp tibiotarsal tubercle plain, not bifurcate as in Scutascirus. Subcapitulum bears 6 pairs of setae: 2 pairs of adoral setae and 4 pairs of subcapitular setae (hg1–4). Idiosoma, dorsal. Dorsal idiosoma heavily sclerotized and the plates well-demarcated. A single dorsal shield present; it may range in size from terminating anteriorly to cupule im to being holodorsal. No papillated line or other marking indicates the separation of the proterosomal and hysterosomal shields. 2 pairs of setae and 2 pairs of setose sensillae present on the proterosomal. Setae c1–h1, c2, and f2 and cupule im present dorsally. Dorsolateral plates (such as present in Scutascirus) absent. Idiosoma, ventral. Coxae I–II fused and coalesce medially to form a sternal shield which often has a prominent apex caudally. Sternal plate complemented with 5–7 pairs of setae. Coxae III–IV fused and may extend laterally and caudally past the genital plates. Genital plates each bear 4 setae; 2 pairs of genital papillae visible underneath the plates. Anal plates bear two pairs of setae (ps1 and ps2). Seta h2 located ventrally near the anal plates. Cupule ih present in close proximity to h2. Legs shorter than the idiosoma, never constricted apically so as to end in lobes. The apices of solenidia, especially on tarsi I, may be swollen. Trichobothrium on leg tibia IV present. Ambulacral claws on either side of a four-rayed empodium present. Males similar, except up to three shields or plates may occur on the dorsal idiosoma (that is the proterosomal shield may not be fused to a hysterosomal plate and up to two hysterosomal plates may be present) and coxae I–IV may be fused into a holoventral shield.
