This volume is the fifth in a series of Taxonomic Guides to the Stick Insects of South East Asia and the eighth book on stick insects by the author. It is the third volume to report on the stick insects of Borneo. This book follows the concept of the first four volumes by the author in this series: A Taxonomic Guide to Stick Insects of Borneo (2016), A Taxonomic Guide to Stick Insects of Borneo Volume II (2017), A Taxonomic Guide to Stick Insects of Singapore (2017) and A Taxonomic Guide to Stick Insects of Sumatra Volume I (2018). The present account is once again lavishly illustrated with beautiful colour photographs of the relevant species of stick insects being discussed in the book.
A Taxonomic Guide to Stick Insects of Borneo (2016) listed 337 Bornean species or subspecies of which 5 new subgenera, 15 new genera and 52 new species were described. Together with these were 5 subspecies, 7 species, 2 genera with revised statuses, 1 generic synonym, 19 specific synonyms, 46 new combination names for Bornean taxa. A Taxonomic Guide to Stick Insects of Borneo Volume II (2017) listed 373 Bornean species or subspecies from 92 genera of which there were 4 new genera with 37 new species. In addition there were 4 new combinations names, 3 new synonyms. This latest volume lists 369 currently recognised Bornean species or subspecies, with 14 new species or subspecies. There are 12 new synonyms, 11 new nomenclatural combinations, 6 nominate subspecies, 11 lectotypes designated, 1 neotype designated and 9 revised statuses.
Even with the description of additional species there has been a decrease in the number of Bornean species. This is because quite a number of synonyms were encountered during the course of this study. Many species of stick insects have been repeatedly described as new; therefore some names have had to be reduced to synonymy. Furthermore, some species were found during this survey to have been misidentified and are not of Bornean origin. These taxa are therefore removed from the Bornean list.
