Wilhelm Ferdinand Erichson
Dr Wilhelm Ferdinand Erichson (26 November 1809 in Stralsund – 18 December 1848 in Berlin) was a trained medical doctor and a German entomologist. He was the author of many articles about insects mainly in '' Archiv für Naturgeschichte''. When writing in Latin, he latinised ''Wilhelm'' to ''Guillelmus'' becoming either ''Guil. F. Erichson'' or ''G.F. Erichson.'' He wrote a paper in 1842 on insect species collected at Woolnorth in Tasmania, Australia, which was the first detailed research published on the biogeography of Australian animals and was very influential in raising scientific interest in Australian fauna. Erichson was the curator of the Coleoptera collections at the ''Museum fur Naturkunde'' in Berlin from 1834 to 1848. Erichson's Scarabaeidae classification is nearly identical to the modern one.

Diving Beetle
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 long, though much variation is seen between species. The European ''Dytiscus latissimus'' and Brazilian ''Megadytes ducalis'' are the largest, reaching up to and respectively. In contrast, the smallest is likely the Australian ''Limbodessus atypicali'' of subterranean waters, which only is about 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. H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copelatus
''Copelatus'' is a large genus of small diving beetles. There are some 470 described species in the genus, found worldwide, but they are most diverse in tropical South America, Africa and South-East Asia. Systematics The genus ''Copelatus'' is divided into several subgenera (''Colepatus'', ''Papuadytes'' etc.), some of which are sometimes treated as separate genera. It may be paraphyletic with respect to the smaller Copelatinae genera '' Lacconectus'' and ''Aglymbus''. The species include: Species * '' Copelatus abonnenci'' Guignot, 1939 * '' Copelatus acamas'' Guignot, 1955 * '' Copelatus advena'' Sharp, 1882 * '' Copelatus aemulus'' Bilardo & Rocchi, 1995 * '' Copelatus aequatorius'' Régimbart, 1899 * '' Copelatus aethiopicus'' Régimbart, 1906 * '' Copelatus agrias'' Guignot, 1954 * '' Copelatus aldabricus'' J.Balfour-Browne, 1950 * '' Copelatus alternatus'' Sharp, 1882 * '' Copelatus amaroides'' Guignot, 1952 * '' Copelatus amatolensis'' Omer-Cooper, 1965 * '' Copelatus ...

Copelatinae
Copelatinae is a subfamily of diving beetles, in the family Dytiscidae. The subfamily contains seven genera: '' Agaporomorphus'', ''Aglymbus'', ''Copelatus'', '' Exocelina'', '' Lacconectus'', '' Liopterus'', and '' Madaglymbus''. Of these, the largest is ''Copelatus'', which has about 470 described species found worldwide, but most diverse in tropical South America, Africa Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area ... and South-East Asia.
