The scale of
measurement given in descriptions of new species is from the centre of the
thorax to the forewing apex.
Information on habitat preference has been gained almost entirely from
light trap surveys of G. Kinabalu (Holloway, 1976), the G. Mulu National
Park (Holloway, 1984), from collections made by Col. M.G. Allen, T.W.
Harman and colleagues in Brunei, by W. Boyd-Wallis in Kalimantan and by
A.H. Kirk Spriggs and Dr S.J. Willott in Sabah. Additional data on the
fauna of softwood plantations and material from the Forest Research Centre
Collection, Sepilok, have kindly been made available by Dr Chey Vun Khen
of the Sabah Forest Department (Chey, 1994). Similar data for Peninsular
Malaysia have been made available by Dr Jurie Intachat of the Forest
Research Institute of Malaysia (FRIM; Intachat, 1995). Some additional
records were made in March, 1997, from sampling during the International
Pilot Course on Environmental Evaluation using Insects as Indicators held
at Universiti Malaysia Sabah: geometrids were used as one indicator group.
Broad vegetation categories were discussed in Part 4 of this series.
Data on geographical range are mainly from the collections of The
Natural History Museum (BMNH), but with some additional data on the
Sumatran fauna that have been made available through the collecting
activities of Dr E. Diehl and other members of the Heterocera Sumatrana
Society: material of Drepanidae and Uraniidae is mostly in the Zoologische
Staatssammlung Munich, (ZSM). Data for Peninsular Malaysia are
supplemented from the collections of Mr H.S. Barlow and FRIM, the latter
particularly through recent surveys conducted by Dr Intachat.
Many host-plant data are drawn from unpublished records of the
International Institute of Entomology. These are collated from material
submitted to the Institute for identification from throughout the
Indo-Australian tropics. Of particular note in recent years are records
from material submitted by the Indian Central Agricultural Research
Institute Station in the Andaman Is. Unpublished records for the
Epipleminae of Taiwan have been provided by Chen (1997) and Mr Shen-Horn
Yen. Plant nomenclature follows Mabberley (1987).
Holotypes of new taxa have been deposited in The Natural History Museum
except where indicated to the contrary.
Nomenclatural details of all genus-group names are to be found in Fletcher
(1979), and are therefore not repeated here. Fletcher did not indicate
generic gender. Whilst the Code of Zoological Nomenclature stipulates that
adjectival species-group names should agree in gender with the genus-group
name, the application of this in the Geometroidea is fraught with
difficulty (Holloway, 1993). Given modern requirements for computerised
database construction, and given the confusion that rectification would be
likely to cause amongst users of biosystematics not familiar with the
niceties of the Latin language, all species names given here have the
orthography of the original description. The reader should also note that
the convention of putting author names in parentheses, where the genus of
combination is not the original one, has not been followed, as the
situation is clear from the synonymy attached to each species treated.
