Cacia tonkinensis is a species of beetle in the family Cerambycidae. It was described by Maurice Pic in 1926. It is known from Vietnam. [1]
Beetles are a group of insects that form the order Coleoptera, in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently. The largest of all families, the Curculionidae (weevils) with some 70,000 member species, belongs to this order. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops.
Maurice Pic was a French entomologist who specialised in Coleoptera. He contributed to Mary-Louis Fauconnet's Catalogue raisonné des coléoptères de Saône-et-Loire and wrote many short papers, many in L'Échange, Revue Linnéenne describing world beetles. His most important work was for Sigmund Schenkling's still very relevant Coleopterorum Catalogus.
Vietnam, officially the Socialist Republic of Vietnam, is the easternmost country on the Indochina Peninsula. With an estimated 94.6 million inhabitants as of 2016, it is the 15th most populous country in the world. Vietnam is bordered by China to the north, Laos and Cambodia to the west, part of Thailand to the southwest, and the Philippines, Malaysia, and Indonesia across the South China Sea to the east and southeast. Its capital city has been Hanoi since the reunification of North and South Vietnam in 1976, while its most populous city is Ho Chi Minh City.
