The Dytiscidae – based on the Greek dytikos (δυτικός), "able to dive" – are the predaceous diving beetles, a family of water beetles. They occur in virtually any freshwater habitat around the world, but a few species live among leaf litter. The adults of most are between 1 and 2.5 cm (0.4–1.0 in) long, though much variation is seen between species. The European Dytiscus latissimus and Brazilian Megadytes ducalis are the largest, reaching up to 4.5 cm (1.8 in) and 4.75 cm (1.9 in) respectively. In contrast, the smallest is likely the Australian Limbodessus atypicali of subterranean waters, which only is about 0.9 mm (0.035 in) long. Most are dark brown, blackish, or dark olive in color with golden highlights in some subfamilies. The larvae are commonly known as water tigers due to their voracious appetite. They have short, but sharp mandibles and immediately upon biting, they deliver digestive enzymes into prey to suck their liquefied remains. The family includes more than 4,000 described species in numerous genera.
Zopheridae is a family of beetles belonging to Tenebrionoidea. It has grown considerably in recent years as the members of two other families have been included within its circumscription; these former families are the Monommatidae and the Colydiidae, which are now both included in the Zopheridae as subfamilies or even as tribe of subfamily Zopherinae. Some authors accept up to six subfamilies here, while others merge all except the Colydiinae into the Zopherinae.
Ripiphoridae is a cosmopolitan family of some 450 described species of beetles sometimes called "wedge-shaped beetles". Ripiphoridae are unusual among beetle families in that many species are hypermetamorphic parasitoids, an attribute that they share with the Meloidae. Members of the family differ in their choice of hosts, but most attack various species of bees or wasps, while some others attack cockroaches or beetles. Many species of Ripiphoridae have abbreviated elytra, and flabellate or pectinate antennae.
The Indiana Open is the Indiana state open golf tournament, open to both amateur and professional golfers. It is organized by the Indiana section of the PGA of America. It has been played annually since 1915 at a variety of courses around the state. The tournament was not played in 1917.
Mecyclothorax is a genus of beetles that contains over 400 described species or subspecies, mostly from the Hawaiian Islands, and Tahiti and Moorea, French Polynesia. Additional radiations have evolved in Queensland, Australia, New Guinea and New Caledonia. The genus has been divided into five subgenera: Eucyclothorax Liebherr 2018 of Australia, Qecyclothorax Liebherr 2018 of Queensland, Australia, Meonochilus Liebherr & Marris, 2009 of New Zealand, Phacothorax Jeannel 1944 of New Caledonia, and the more widely distributed subgenus Mecyclothorax Sharp 1903 [in Australia, the Sundas, New Zealand, the Society Islands, and Hawaii]. The adelphotaxon to Mecyclothorax is hypothesized to consist of the genera associated with Amblytelus Blackburn, also distributed in Australia, and therefore the evolutionary history of Mecyclothorax commenced in Australia.
Dyschirius is a genus of beetles in the family Carabidae:
Orphinus is a genus of beetles in the family Dermestidae, the skin beetles. The genus is distributed in Africa, Asia, and the Australian region, especially in tropical areas; at least one species is cosmopolitan. There are about 88 species.
