Bornean Geometridae of the subfamilies Sterrhinae (176 species
in 21 genera) and Larentiinae (199 species in 56 genera) are described. For each
species a diagnosis and the geographical range are given and, where known,
details of habitat preference and biology. Summary lists are provided of the new
taxa described (9 genera, 55 species and 2 subspecies) as well as of numerous
other taxonomic changes. A checklist of all species summarises the fauna.
In an introductory section the biogeographic and ecological composition
of the Bornean geometrid fauna as a whole is presented within a regional and
global context. It constitutes about one quarter of the known Oriental Region
fauna. The higher classification of the whole family is reviewed and a tentative
For each subfamily, family-group names are listed and some attempt made
to resolve classification at a tribal level. Two lineages are recognised within
the Sterrhinae, and the tribe Trichopterygini is suggested to bear a
sister-relationship to the remainder within the Larentiinae.
A final section notes errata in, and addenda to the previous two
geometrid parts of the series, with description of two new ennomine species and
biological notes on Naxa guttulata Warren, a fern-feeder.
