P. stramineus was originally named Erirhinus stramineus by Broun in 1881.Broun, T. 1881: Manual of the New Zealand Coleoptera. Part II. Colonial Museum and Geological Survey Department, Wellington. [See p. 709] Then, in 1926, Marshall described a new genus called Dorytomodes, into which he provisionally transferred all species placed by Broun in Erirrhinus [=Erirhinus].Marshall, G.A.K. 1926: Some new Curculionidae from New Zealand (Col.) Annals and Magazine of Natural History (9), 18(103): 1-16, plate I. [See p. 10; '... Erirrhinus, Broun (nec Schh.), must provisionally be merged in Dorytomodes.'] Dorytomodes was subsequently sunk as a synonym of Peristoreus by Edward S. ("Ted") Gourlay in 1950.Gourlay, E.S. 1950: Auckland Island Coleoptera. Transactions of the Royal Society of New Zealand, 78(2-3): 171-202, plates 21-23. Full article (PDF) [See p. 197; 'n.syn.']
P. stramineus has been found in the northern North Island (including nearby offshore islands, e.g. Poor Knights), south to the Hawke's Bay Region.Kuschel, G. 1982: Apionidae and Curculionidae (Coleoptera) from the Poor Knights Islands, New Zealand. Journal of the Royal Society of New Zealand, 12(3): 273-282. [See p. 280] It has also been reported from the South Island (Banks Peninsula), as a seed predator in fruit of Hoheria angustifolia.Sullivan, J.J.; Burrows, C.J.; Dugdale, J.S. 1995: Insect predation of seeds of native New Zealand woody plants in some central South Island localities. New Zealand journal of botany, 33(3): 355-364. [See p. 359]
