Five species of Phasmida which have not previously been recorded from Borneo have been found in Brunei, Sarawak and Sabah. One species, Planispectrum bengalensis (Redtenbacher, 1906), represents a genus which is previously unrecorded from Borneo. Six new synonyms are given and an old synonym is corrected. The eggs of Asceles conicipennis, Sosibia peninsularis and Orthonecroscia pulcherrima are described and illustrated for the first time. The lectotypes of four species, Asceles acutegibbosus Redtenbacher 1908, Ocellata atrosignata Redtenbacher, 1908,
Lopaphus hadrillus Westwood, 1859, and Platymorpha bengalensis Redtenbacher, 1906, are designated.
