from the highlands of Mendolong, Sipitang District, and the other from the lowland rainforests of Danum

rostral sutures, preanal pores absent; nuchal collar starts from back of head, and relatively short tail (14.8%
SVL). The new lowland species from Danum Valley, Dibamus vorisi, differs from all congeneric species
in the following combination of characters: SVL to 90.1 mm; body relatively slender, body width 3.9%
SVL, postoculars two; midbody scale rows 20; subcaudals 33 in a male, 11 in a female; frontonasal entire;
nasal suture complete; labial suture absent; preanal pores absent; nuchal collar absent; pale body band
