Remarks
This specimen agrees well with previous illustrations and description of D. peralta (Vredenburg 1928; Borkar & Kulkarni 2019), although with a height of 45 mm it is somewhat larger than the maximum height of 35 mm reported by Borkar & Kulkarni (2019). A very similar species is Dosinia boettgeri Martin, 1879 from the Late Miocene of Java (see Leloux & Wesselingh 2009: pl. 17 figs 6–8), from which D. peralta differs mainly by its more acute anterodorsal margin. Another similar species is Dosinia exasperata from Pleistocene strata in the Philippines (Shuto 1971), which has more irregular commarginal sculpture and the sculpture is scaly on the posterodorsal margin, unseen in D. peralta. Extant specimens of Dosinia exasperata are more roundish and have more steeply sloping antero- and posterodorsal margins.
