Remarks

• Systematics: Although the condition of the single type specimen is rather poor, it is considered that enough can be seen to determine that this species is not congeneric with C. banksiae Maskell. Its exact generic placement is somewhat uncertain but is here tentatively placed in Sinhalacoccus Hodgson gen. nov. as it shares the following characters with S. koebeli: (i) dorsal derm quite thick and dense in mature specimens, with reticulate areolations; (ii) a dorsal medial longitudinal area present, containing few or no setae, ducts or pores, extending anteriorly from anal plates although it is not clear how far forwards it extends; (iii) dorsal setae conical and spinose; (iv) large flat, closed dorsal pores, here considered to be preopercular pores, present on either side of medial area; (v) dorsal tubular ducts of three types, with largest situated away from margin; (vi) marginal simple pores present in association with line of marginal setae; (vii) stigmatic clefts each containing stigmatic spines in a triangular area on dorsum slightly away from margin; (viii) anal plates with anterior and posterior margins subequal in length; (ix) each anal plate with four small setae near apex; (x) multilocular disc-pores mostly each with 10 loculi; (xi) ventral tubular ducts forming a submarginal band; (xii) with a tubular duct type present ventrally in transverse bands across abdominal segments anterior to multilocular disc-pore bands; (xiii) antennae eight segmented; (xiv) legs well developed, each without a tibio-tarsal articulatory sclerosis, and (xv) claw digitules both broad but perhaps with one slightly narrower than other. (Hodgson, 2026) Slide-mounted specimens of S. fryeri differ from those of S. koebeli as follows (characters for S. koebeli are given in brackets): (i) marginal spinose setae far fewer, numbering about 22 between anterior stigmatic clefts (with 35‒46 between clefts); (ii) each stigmatic cleft containing only 3 stigmatic spines (with 8‒16 stigmatic spines in each cleft); (iii) multilocular disc-pores few, restricted to posterior 5 abdominal segments (abundant, present widely throughout abdomen and on meso- and metathorax also); and (iv) spiracular disc-pore bands narrow, each containing fewer than 40 pores (each disc-pore band broad, containing 100+ pores). In addition, according to Green (1909: 1922), their appearances in life are very different. The dorsum of S. fryeri does not appear to have the prominent ridges of threads described for S. koebeli but apparently does have “A long, stout, curling white filament [which] arises from near the posterior extremity, on each side, extending upwards and backwards. Several waxy spots, on each side of the abdomen, possibly mark the position of other similar filaments that have been lost.” No structures were located on the dorsum of the slide-mounted specimen that could have secreted these filaments. Perhaps the curling filaments were fungal, although there was little sign of this in the specimen.(Hodgson, 2026).
• Structure: “Adult female ovate, highly convex, depressed laterally; with a strongly marked umescence on each side of the dorsum. Colour dull olivaceous brown, dusted with mealy secretion which is condensed into a thick covering on the marginal area. Dense, vertical waxy bands of an ochreous white colour, arise from the stigmatic areas on each side, extending far onto the dorsum. A long, stout, curling white filament arises from near the posterior extremity, on each side, extending upwards and backwards. Several waxy spots, on each side of the abdomen, possibly mark the position of other similar filaments that have been lost.” (Green, (1922: 1028) S;lide mounted body large and oval, with anterior end rather pointed; broadest across abdomen; with shallow stigmatic clefts; anal cleft perhaps 1/8th body length. Body 7.5 mm long and possibly 5.7 mm wide (Green (1922: 1028) says body length 8 mm). (Hodgson, 2026).
