Countries & Regions Covered in this Website

The morphotypes and described species illustrated in this publication are primarily from Borneo, which is comprised of Malaysia (the states of Sabah and Sarawak), the Sultanate of Brunei, and Indonesia (the provinces of Kalimantan Barat, Kalimantan Selatan, Kalimantan Tengah and Kalimantan Timur) (Kalimantan West, South, Central and East respectively). In the case of the Thyrididae, for reasons not understood, the Bornean fauna has significantly fewer records than adjacent or nearby areas such as Peninsular Malaysia and Sumatra. For this reason this work on the thyridids includes species known to occur in the region even though they have not yet been reported from Borneo.

The distribution of some Bornean pyralids and thyridids may extend throughout the Oriental and Australian biogeographic regions where moist tropical forest biotopes have historically occurred. This includes the following countries, reading from NW to SE: 

Sri Lanka, India (primarily the States and Union Territories of Karnataka, Kerala, Tamilnadu, West Bengal, Meghalaya, Assam, Mizoram, Manipur, Nagaland, Andaman Islands & Nicobar Islands), Bangladesh, Myanmar (Burma), Thailand, Vietnam, Cambodia, Lao People's Democratic Republic (Laos), Malaysia (Peninsula), Singapore, Philippines, China (south, Hong Kong), Taiwan, Japan (Ryuku Islands), Indonesia (Sumatra, Java, Bali, Sumbawa, Sulawesi and other smaller island groups) and parts of the Australasian region including Timur, New Guinea (West Irian, Papua New Guinea, New Britain), Australia (N.T. & Q.). For practical purposes, we have excluded most species occurring in Sri Lanka, India (except the Andaman and Nicobar Islands), Bangladesh, China (except the south), the island of New Guinea and Australia. However if a species occurs, for example, in both India and New Guinea, but not in SE Asia, it is included as being likely to occur in Borneo, even though the broad disjunct range might suggest a covert species complex.
