Amarygmini
Amarygmini is a tribe of darkling beetles in the family Tenebrionidae. There are more than 80 genera in Amarygmini. Description Adult Amarygmini are active long-legged beetles that fly readily. They have an unhidden membrane between the front margin of the Clypeus (arthropod anatomy), clypeus and the Labrum (arthropod mouthpart), labrum. In males, the base of the aedeagus is asymmetric, more or less acutely drawn out, directed towards the right and fused with the parameres. The dorsal side of the aedeagus is directed towards the dorsum of the body. Most larvae of Amarygmini have a regular, oval excavation on the ninth abdominal Tergum, tergite. The Australian ''Chalcopteroides'' is an exception, instead having short urogomphi borne on an oblique projection. Life cycle Like other beetles, Amarygmini go through Holometabolism, complete metamorphosis with the life stages of egg, larva, pupa and adult. Amarygmini are one of several tenebrionid groups to have long-lived larvae an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amarygmus
''Amarygmus'' is a genus of Darkling beetle, darkling beetles (family Tenebrionidae). It is in the tribe Amarygmini and is the oldest genus of the tribe. The genus occurs in Australia (mainly in the north), New Guinea, Hawaii, Africa and Eurasia. Description ''Amarygmus'' is a variable genus. Some descriptions of adults are given below: * In species found in Borneo, the apices of the Mandible (arthropod mouthpart), mandibles are bifid and not truncate. The femora of the legs are usually enlarged in the middle or at the apical third. There are hairs usually on the Clypeus (arthropod anatomy), clypeus, legs, antennomeres and, frequently, as a sexual character on the underside of males. Traits found in related genera, such as long, erect hairs on Prothorax, pronotum and Elytron, elytra (found in ''Bunamarygmus'') are absent. * In species found in Australia, the body is usually oval (rarely subparallel), convex and glabrous. Body length ranges from 6 to 15 mm. The colour is usually ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chalcopteroides
''Chalcopteroides'' is a genus of darkling beetle, defined by Embrik Strand in 1935, and replacing the older name ''Chalcopterus'' which was preoccupied. The type species is ''Chalcopterus iridicolor''. The genus occurs throughout Australia. Description ''Chalcopteroides'' range from 6 to 23 mm in length. They are oblong in shape, glabrous and usually a metallic blue or green colour. The mandibles lack a sulcus and have either truncate or rounded apices. The lateral margins of the pronotum are complete. The Elytron, elytra usually have only superficial and minute punctures (sometimes they have impressed striae). The metaventrite is long. The tarsal vestiture (hairs on the tarsi) is mostly black. Ecology Some ''Chalcopteroides'' are known to live in soil. Additionally, arthropod fragments have been found in guts of some species, suggesting a Scavenger, scavenging or Predation, predatory lifestyle. Species Below are the species of this genus: * ''Chalcopteroides acuta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johannes Von Nepomuk Franz Xaver Gistel
Johannes von Nepomuk Franz Xaver Gistel ''Gistl(11 August 1809 – 9 March 1873) was a German naturalist. He worked at the Museum of Natural History in Regensburg, and wrote on a range of topics under the pseudonyms Garduus and G. Tilesius (an anagram). His contributions to entomology include descriptions of species, with many new names he proposed now mostly relegated to synonymy. Gistel's father Franz Xaver Gistl (1783–1815) worked at the a royal riding school and died in 1813. Gistel was raised by his mother, Maria Anna Gistl (née Hahn, born 1772) and his older sister Katharina Leonora (born 1808). School records indicate that his original name was Lorenz Gistl. He was educated in schools in Rempart and Schönfeld before joining the royal gymnasium in Munich in 1822. His degrees in medicine and philosophy appear to be fake. He wrote works on entomology such as ''Die jetzt lebenden Entomologen, Kerffreunde und kerfsammler Europa’s und der übrigen Continente'' (1836) and ...
