In a survey of the brown dorcopsis, Dorcopsis muelleri, on Salawati Island, Papua, Indonesia, 2 new species were found in the stomach. Dorcopsistrongylus ewini n. sp. can be differentiated from its congeners in having the proximal end of the spicule twisted and from Dorcopsistrongylus labiacarinatus in having shorter intestinal diverticula and in the proportions of the elements of the ovejector. Dorcopsistrongylus salawatiensis n. sp. can be differentiated from its congeners in having bilobed lateral lip-like elements and an elongated terminal bulb of the esophagus. A survey of other Dorcopsis and Dorcopsulus spp. may reveal more species of Dorcopsistrongylus.
