Genus Cilliba von Heyden, 1826

Type species: Notaspis cassideus Hermann, 1804 , by original designation

Diagnosis: Typical representative of higher Uropodoidea sensu Athias­Binche & Evans (1981), with well marked pedofossal grooves (FP I–FP IV). Cuticle well sclerotised, brown in colour; body flat, subcircular, cuticle smooth or punctate, may be sculptured centrally with small pits. Marginal shield broad with ca 6 pairs of lyrifissures (id), separated from dorsal shield or fused with it anteriorly. Marginal setae numerous, short, hook­like. Submarginal setae simple, shorter than dorsal setae. Dorsal setae simple or lanceolate, each accompanied by a circular porus. Five pairs of simple sternal setae (st1–st5), and three pairs of lyrifissures: iv1 near camerostome, iv2 near setae st5 and iv3 below pedofossal grooves IV. Epigynium of female large, tongue­shaped, articulated below the level of coxae IV, ornamented, with one pair of lyrifissures located near the posterior edge of the shield (ig), covering endogynial shield (sg) and endogynial sac (seg). Operculum (opr) of male oval, surrounded posteriorly by semicylindrical postgenital element (pg), with one pair of eugenital setae (plg), situated at a level between coxae III and IV. Five pairs of simple ventral setae (v1–v5). Two pairs of simple adanal setae (Ad1, Ad2) and unpaired postanal seta (Pa). Each pair of ventral setae accompanied by circular porus. Idiosomal chaetotaxy for immatures and adults as in Table 1 . Peritremes short, Vshaped, without poststigmatic section, located near the margins of the body. Two pairs of lyrifissures (il) and several pairs of globular glands (gv, gl) located in and between pedofossal grooves and on opisthosoma. Tritosternum 6­branched, with broad base. Hypostomal setae h1 longer than the others, h2 short, h3 = h4, h4 longer than h2. Tarsus I without claws, but with long terminal seta; leg chaetotaxy as in Table 2 .
