Remarks

• Systematics: This species is clearly closely related to C. bernardi and C. ficoides. They are all from the Oriental Region. Cerochiton javanensis has the same arrangement of 8-shaped pores and quinquelocular disc-pores at the apex of each stigmatic band, and each species has two sizes of tubular duct, with the broader duct occurring along margins of each lattice-like line of pores. Like C. ficoides, C. javanensis has a bifurcated posterior stigmatic pore band (non-bifurcated in C. bernadi) but C. ficoides differs in having: (i) some multilocular disc-pores present in transverse bands across abdominal segments VI and VII (absent in C. javanensis); and (ii) a single cribriform plate submedially on each side of abdominal segment IV—although Taiwanese specimens with submedial groups of 3-7 plates (submedial groups of 5-8 plates on each side in C. javanensis). In addition, the layout of the lines of small 8-shaped pores on C. ficoides and C. javanensis appears to be different: the submarginal line on the venter of C. javanensis passes through the spiracles and antennae whereas on C. ficoides it is much more medial; in addition, there are two transverse lines medially on the dorsum of the head and prothorax of C. javanensis whereas these are absent on C. ficoides. (Hodgson & Williams, 2016)
• Structure: Adult female with last group of pores in bifid spiracular furrow reduced in number (9-15); only outer ring of 8-shaped pores present; without transverse rows of multilocular pores on venter; lacelike pattern on dorsum composed of double or triple rows of 8-shaped pores (Lambdin & Kosztarab, 1977a). Adult females of C. javanensis are characterised by the following combination of character-states: (i) dorsum with a reticulate pattern of 8-shaped pores; (ii) lines of reticulation made up of smallest 8-shaped pores; (iii) largest 8-shaped pores restricted to within and around apices of each stigmatic band; (iv) apex of each stigmatic band with groups of 10–18 sunken 8-shaped pores in centre; (v) cribriform plates present in a submedial group of 5–8 on each side of abdominal segment IV; (vi) tubular ducts of two sizes on dorsum, broadest in a line on either side of each reticulation but absent from posterior abdominal segments; (vii) multilocular disc-pores absent; (viii) stigmatic pore bands bifurcated; (ix) spiracular disc-pores near spiracles few but more abundant in each stigmatic pore band apex, and (x) legs stubs absent.
