Remarks

• Systematics: This species appears most similar to C. ehretiae, C. rhodesiensis and C. tangandae due to the presence of multilocular disc-pores extending anteriorly onto the metathoracic segments (although only on 1 out of 5 specimens of C. giliomeei). Adult female C. giliomeei can be distinguished from the others in this group by the following character states: (i) lack of dorsal tubercles (present on C. ehretiae, C.rhodesiensis and C. tangandae); (ii) few (4–6) preopercular pores (C. ehretiae with 6–10, and many more on C. rhodesiensis, 21–32, and C. tangandae, 18–28); (iv) multilocular disc-pores with mainly 10 loculi on segment VII but becoming fewer more anteriorly (as on C. rhodesiensis, but all with 5 loculi on C. ehretiae or with up to 12 loculi on C. tangandae); and (v) multilocular disc-pores also present sporadically on metathoracic segments (extending to at least mesothorax on C. rhodesiensis and C. tangandae). (Łagowska & Hodgson, 2019)
• Structure: Adult female C. giliomeei can be diagnosed by a combination of the following features: (i) dorsal derm with clear areolations; (ii) dorsal microducts of perhaps 2 types; (iii) dorsal tubular ducts, dorsal tubercles and pocket-like sclerotizations absent; (iv) preopercular pores few (4–6), present in a linear group just anterior to anal plates, (v) anal plates together quadrate, each plate with a subdiscal seta, 1 apical seta and 3 or 4 subapical setae; (vi) numerous marginal setae, each strongly setose, straight or slightly curved; (vii) each stigmatic area with 3 stigmatic spines, each median spine about 1.5x longer than lateral spines; (viii) ventral tubular ducts absent; (ix) multilocular disc-pores, each with 6–10 loculi, present on all abdominal segments and sporadically on metathorax; and (x) each claw without a denticle.
