Six new species forming the Sumbana species group in genus Nemophora Hoffmannsegg 1798 from Indonesia

NEWS - Sumbawa longhorn ( Nemophora sumbana Kozlov, sp. nov.), Timor longhorn ( Nemophora timorella Kozlov, sp. nov.), shining shade longhorn ( Nemophora umbronitidella Kozlov, sp. nov.), Wegner longhorn ( Nemophora wegneri Kozlov, sp. nov.), long brush longhorn ( Nemophora longipeniculella Kozlov, sp. nov.), and short brush longhorn ( Nemophora brevipeniculella Kozlov, sp. nov.) from the Lesser Sunda Islands in Indonesia. The Lesser Sunda Islands consist of two parallel, linear oceanic island chains, including Bali, Lombok, Sumbawa, Flores, Sumba, Sawu, Timor, Alor, and Tanimbar. The oldest of these islands have been continuously occurring for 10–12 million years. This long period of isolation has allowed significant in situ diversification, making the Lesser Sundas home to many endemic species. This island chain may act as a two-way filter for organisms migrating between the world's two great biogeographic regions, Asia and Australia-Papua. The recognition of a striking cli...

Golden tortoise beetle (Charidotella sexpunctata)

Kepik emas or golden tortoise beetle ( Charidotella sexpunctata ) is a type of leaf beetle species in the Chrysomelidae family, up to 14mm long and bright golden in glass discs. These insects usually live on Ipomoea carnea trees that grow in environments close to water. C. sexpunctata takes refuge in a transparent disc consisting of three parts with four signs as fals legs, a pair of antennas and six legs. This beetle is able to change color if it feels threatened by flowing liquid between the cuticles and the glittering gold color turns into blood red or worn brown. Kepik emas usually lay eggs up to 20 items, white and attached to the branches or on the underside of the leaves. Yellowish or reddish brown larvae will appear from eggs that hatch within 5 to 10 days. Adults and larvae eat leaves which cause large holes.
