The mountain pygmy possum ; also simply known as the burramys, is a small, mouse-sized nocturnal marsupial of Australia found in dense alpine rock screes and boulder fields, mainly southern Victoria and around Mount Kosciuszko in Kosciuszko National Park in New South Wales at elevations from 1,300 to 2,230 metres. At almost 14 cm (5.5 in), its prehensile tail is longer than its 11 cm (4.3 in) combined head and body length. Its diet consists of insects, fleshy fruits, nuts, nectar and seeds. Its body is covered in a thick coat of fine grey fur except for its stomach, which is cream coloured; its tail is hairless. On the underside of the female's body is a pouch containing four teats. This possum is the only extant species in the genus Burramys. It is also the only Australian mammal restricted to alpine habitat.
Microlepidoptera (micromoths) is an artificial grouping of moth families, commonly known as the "smaller moths". These generally have wingspans of under 20 mm, so are harder to identify by external phenotypic markings than macrolepidoptera. They present some lifestyles that the larger Lepidoptera do not have, but this is not an identifying mark. Some hobbyists further divide this group into separate groups, such as leaf miners or rollers, stem or root borers, and then usually follow the more rigorous scientific taxonomy of lepidopterans. Efforts to stabilize the term have usually proven inadequate.
The Cossidae, the cossid millers or carpenter millers, make up a family of mostly large miller moths. This family contains over 110 genera with almost 700 known species, and many more species await description. Carpenter millers are nocturnal Lepidoptera found worldwide, except the Southeast Asian subfamily Ratardinae, which is mostly active during the day.
Copromorphidae, the "tropical fruitworm moths", is a family of insects in the lepidopteran order. These moths have broad, rounded forewings, and well-camouflaged scale patterns. Unlike Carposinidae the mouthparts include "labial palps" with the second rather than third segment the longest. With other unusual structural characteristics of the caterpillar and adult, it could represent the sister lineage of all other extant members of this superfamily. The genus Sisyroxena from Madagascar is also notable for its unusual venation and wing scale sockets.
The Tineodidae or false plume moths are a family of moths with in some cases unusually modified wings: Like in some related moths, the wings of several Tineodidae are decomposed into several rigid spines. This is a small family, with about a global total of 20 species described to date; some undescribed species are known or suspected to exist however. They seem to be of Australian origin, where they are most diverse, but range through the Wallacea to Southeast and South Asia, and into the Pacific to the Marquesas Islands.
The Depressariinae – sometimes spelled "Depressiinae" in error – are a subfamily of moths in the superfamily Gelechioidea. Like their relatives therein, their exact relationships are not yet very well resolved. It has been considered part of family Elachistidae sensu lato or included in an expanded Oecophoridae. In modern classifications they are treated as the distinct gelechioid family Depressariidae.
Xyloryctidae is a family of moths contained within the superfamily Gelechioidea described by Edward Meyrick in 1890. Most genera are found in the Indo-Australian region. While many of these moths are tiny, some members of the family grow to a wingspan of up to 66 mm, making them giants among the micromoths.
Achthina ctenodes is a moth in the family Dudgeoneidae, and the only species in the genus Achthina. It is found in Kenya.
Dudgeonea leucosticta is a moth in the Dudgeoneidae family. It is found in India, Sri Lanka and Malaysia. Two subspecies are recognized. Nominate subspecies from Asia and D. l. sierraleonensis from Sierra Leone.
