Orangescirula Bu & Li, 1987

Historical review.

Bu and Li (1987a) erected Orangescirulinae and Orangescirula for a new species, Orangescirula yongchuanensis . Smiley (1992) described Orangescirula kethleyi . Corpuz-Raros (1996e) described Orangescirula filipina .

Diagnosis.

Gnathosoma. Pedipalps 5-segmented and reach beyond the subcapitulum by at most the distal half of the tibiotarsi. Basifemoral seta simple or spine-like. Telofemoral seta spine-like. Pedipalps end in a stout claw. Subcapitulum bears 6 pairs of setae: 2 pairs of adoral setae and 4 pairs of subcapitular setae (hg1 - 4). Setae hg1 long and bent.

Idiosoma, dorsal. Proterosoma covered in a shield which bears 4 pairs of setae: 2 pairs of simple setae (lps and mps) and 2 pairs of setose sensilla (at and pt). Dorsal hysterosoma median plate present, fused to proterosomal shield; 1 to 5 pairs of dorsolateral plates present. Plates and shields smooth or reticulated. Seven pairs of setae present on the dorsal hysterosoma (c1 - f1, c2, h2). Unsclerotized integument striated.

Idiosoma, ventral. Coxae I-II fused, coxae III-IV fused; coxae may coalesce medially for form a sternal shield. Each pair of coxae complemented with 3 pairs of setae. The genital plates each bear 4 setae; 2 pairs of genital papillae visible underneath the plates. 4-9 pairs of setae present on the integument between coxae II and the genital plates. Anal plates complemented with 2 pairs of setae (ps1-2). Two pairs of setae (h2, pa) located on the integument near the anal plates. Cupule ih present in close proximity to h2. Legs shorter than idiosoma; they are never constricted apically so as to end in lobes. Trichobothrium on leg tibia IV present. Ambulacral claws on either side of a four-rayed empodium present.
