Spissustreptus strigilectus is described as a new species from a male specimen collected in the Kabili-Sepilok Forest Reserve, northern Sabah. Although showing some affinity with the sympatric S. hosei (Pocock, 1892), strigilectus differs from all known members of the genus by the presence of an elongated, medially directed, process on the arculus region of the gonopod. The two Phillippine species named Spirostreptus moseleyi Pocock, 1893, and Spirosteptus foveolatus Karsch, 1881, are tentatively referred to this genus, with historical commentary, new combination for both names.
