Gergithus Pigrans
''Gergithus'' is a genus of tropical Asian planthoppers in the family Issidae, erected by Carl Stål in 1870. Like all planthoppers, adults feed on plant sap and are capable of escaping by leaping. The genus like other members in the tribe appears somewhat rounded and beetle-like, in some cases, with a mimetic resemblance to ladybird beetles. Species are mostly distributed in the Indomalayan Realm. Description The genus is closely related to ''Hemisphaerius'' but differs in having longer frons (forehead) and legs. The frons lacks a median keel (carina) or tubercles on the frons, pronotum or mesonotum. The rounded tegmen which resembles the elytra of beetles are often patterned. Although some species show variations in pattern, many species can be recognized on the basis of the patterns. Species ''Fulgoromorpha Lists On the Web'' includes: # '' Gergithus bimaculatus'' # '' Gergithus bipustulatus'' # '' Gergithus complicatus'' # '' Gergithus conspicularis'' # '' Gergithus ...

Carl Stål
Carl Stål (21 March 1833 – 13 June 1878) was a Swedish people, Swedish entomologist specialising in Hemiptera. He was born at Karlberg Castle, Stockholm on 21 March 1833 and died at Frösundavik near Stockholm on 13 June 1878. He was the son of architect, author and officer Carl Stål then Colonel, Swedish Corps of Engineers. He matriculated at Uppsala University in 1853, studying medicine and passing the medico-philosophical examination in 1857. He then turned to entomology and completed his Ph.D. at the University of Jena in 1859. The same year he became assistant to Carl Henrik Boheman in the Zoological department of the Swedish Museum of Natural History in Stockholm, where, in 1867, he was appointed keeper with the title of professor. He made collecting trips in Sweden and throughout Europe and visited other museums including the collection of Johan Christian Fabricius in Kiel. His study of the Fabrician types resulted in his "Hemiptera Fabriciana". A significant part of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
