Cascolus ravitis
Description Holotype of Cascolus ravitis, exoskeleton and soft parts (OUMNH C.29698): (a–u) ‘virtual’ reconstructions (a,b,f,h–k,m–u are stereo-pairs); (v) specimen in rock. The exact boundary between structures such as body and limbs, as indicated by colour changes, is somewhat arbitrary. (a) Dorsal view. (b) Ventral view. (c) Anterior part of head, appendages omitted, ventral view. (d) Posterior part of trunk, appendages omitted, ventral view. (e) Right lateral view. (f) Part of trunk, dorsal view. (g) Head and most of the trunk, appendage 1 omitted, posterodorsal view. (h) Head with appendages and trunk segments 1 and 2 with appendages omitted; ventral view. (i) Anteroventral view. (j) Limb base and proximal part of antennules, right ventral oblique view. (k) Antennae, right anteroventral oblique view. (l) Anterolateral view. (m,n) Mandible, left limb: posterior oblique (m) and right anteroventral oblique (n) views. (o) Maxillula, left limb, posterior oblique view. (p) Sternites 3–6, anteroventral view, appendages omitted. (q) Maxilla, left limb, posterior oblique view. (r–t) Trunk appendage 2, left limb: gnathobase (r) and complete limb (s) posterior oblique views; and inner proximal part of endopod (t) posterior oblique medial view. (u) Trunk appendage 5, left limb, posterior oblique view. ai, axial inflation; as?, apodous segments?; ba, basipod; bi, bell-shaped inflation; e1, e2, epipods; en, endopod; ex, exopod; f1–f3, flagella; fu, furrow; hi, indentation in anterior margin of the head shield; gn, coxal gnathobase; h1–h5, head appendages; hr, half-ring of trunk tergite; ie, inflation adaxially forward of each eye (‘eye ridge’); la, labrum; lb, limb base; no, node; or, occipital ring; pa, precoxal area; pe, pedunculate eye; t1–t9, trunk appendages; te, end of the trunk, masked by extraneous matter; tr, trunk; tu, tubercle(s). Numbers refer to trunk segments and trunk tergites/sternites as appropriate. Arrows in (m-o, t) indicate podomere boundaries. Arrow in (s,u) indicates a spine/seta. Scale bars: (a–q), (s–v) are 0.5 mm; (r) is 0.1 mm.
