Remarks

• Systematics: C. ghesquierei is clearly a member of the C. rusci-group but differs from the other members of this group in having the following combination of characters: (i) absence of ventral tubular ducts in cephalic region and often on abdomen; (ii) stigmatic setae on each side meeting between clefts and extending from near each eyespot a long way past each posterior cleft; also often with a few present between eyespots anteriorly; (iii) each stigmatic setal group broadening to 4 setae deep in each cleft, and with non-marginal stigmatic setae extending a long way along margin laterally; (iv) stigmatic setae sharply cone-shaped, (v) presence of only 1-5 marginal setae on each side laterally between clefts and (vi) large dorsal setae on each anal plate all located near posterior margin. In almost entirely lacking ventral tubular ducts, C. ghesquierei is similar to C. balachowskyi, C. singularis and C. galeatus. C. singularis differs from the other 3 species in having a band of stigmatic setae around the entire margin (absent from some parts of the margin on other 3 species). It also resembles C. galeatus, particularly in having the large dorsal setae on the anal plate restricted to near the outer margins of each plate but, based on the available material, differs from C. galeatus in having many more stigmatic setae on each side, meeting laterally between the clefts. It is possible that C. ghesquierei is a synonym of C. galeatus but, based on the available specimens, they are easily separable.
• Structure: Unmounted material. The waxy test of 80 year-old dried specimens rather clear yellow but some clearly showing a basic structure similar to that of C. rusci, with a series of marginal plates, anterior 2 lateral pairs each with white stigmatic lines, plus a larger dorsal plate with a central dark nucleus. With wax removed, younger specimens with a central dorsal dome and a short caudal process. Mounted material. Body rather roundly oval and probably fairly convex, with shallow stigmatic clefts; lateral tubercles distinct although small. Caudal process short and stout, probably directed rather upwards. Length of young specimens 1.6-2.5 mm, width about 1.0-1.5 mm.
