Systematics: Discochiton mancum belongs to the group of Discochiton species that have preopercular pores associated with all four clear areas. It differs from others in this group in having the following combination of characters: (i) only 3 stigmatic spines in each stigmatic cleft; (ii) usually fewer than 12 preopercular pores associated with each clear area; (iii) rather long stigmatic spines, with median spine frequently shortest and (iv) dorsal setae rather long, each 20+ μm long, with a blunt apex. (Hodges & Williams, 2018)
Structure: “Adult female flat, deltoid, with rounded angles, usually asymmetrical, always narrower in front. Colour dark castaneous with a narrow hyaline border and with hyaline canals extending inwards from each stigmatic cleft. Dorsum with a more or less well defined, thin, colourless, polygonal, waxy plates.” “Length 4 to 4.5 mm. Breadth across abdomen 2.75 to 3 mm.” (Green, 1922, p. 1023). (Hodgson & Williams, 2018) Slide-mounted adult female. Body broadest posteriorly, slightly more pointed anteriorly; most specimens showing some asymmetry. Length 3.0–4.5 mm, width 2.0–2.75 mm.
