Leptofoeninae
Pelecinellidae is a small family of chalcidoid wasps, formerly treated as the subfamily Leptofoeninae within Pteromalidae. They, like many small chalcidoids, are brilliantly metallic. The subfamily contains three genera, '' Nefoenus'', '' Doddifoenus'' (with four species) and ''Leptofoenus'' (with five extant species). The species '' Doddifoenus wallacei'' is the largest known chalcidoid wasp, reaching nearly in length (including ovipositor).Krogmann, L., Burks, R.A.

Chalcidoidea
Chalcid wasps (, , for their metallic colour) are insects within the superfamily Chalcidoidea, part of the order Hymenoptera. The superfamily contains some 22,500 known species, and an estimated total diversity of more than 500,000 species, meaning the vast majority have yet to be discovered and described. The name "chalcid" is often confused with the name "chalcidid", though the latter refers strictly to one constituent family, the Chalcididae, rather than the superfamily as a whole; accordingly, most recent publications (e.g.,) use the name "chalcidoid" when referring to members of the superfamily. Most chalcid wasps are parasitoids of other insects, though other life styles are known, with the herbivorous fig wasps acting as pollinators. Various species are used as biological pest control agents or in scientific research. Description Chalcidoids are generally small wasps, averaging 1.5 mm in length and usually being less than 3 mm. The body is often metallic in colour. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pteromalidae
The Pteromalidae are a very large family of mostly parasitoid wasps, with some 3,450 described species in about 640 genera (the number was greater, but many species and genera have been reduced by synonymy in recent years). The subfamily-level divisions of the family are highly contentious and unstable, and the family is thought to be "artificial", composed of numerous, distantly related groups (polyphyletic). Accordingly, details of their life histories range over nearly the entire range possible within the Chalcidoidea, though the majority are (as with most chalcidoids) parasitoids of other insects. They are found throughout the world in virtually all habitats, and many are important as biological control agents. The oldest known fossil is known from the Early Cretaceous. In essence, a "pteromalid" is any member of the Chalcidoidea that has five-segmented tarsi and does not have the defining features of any of the remaining families with five-segmented tarsi. It is highly prob ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Leptofoenus Rufus
''Leptofoenus'' is a genus of wasp in the family Pelecinellidae found in South America, Central America, and southern North America. The genus contains five living species and one extinct species known from early Miocene Burdigalian stage Dominican amber deposits on the island of Hispaniola. With body sizes ranging from ''Leptofoenus'' species are larger than nearly all other species in Chalcidoidea. The genus bears a notable resemblance to the wasp families Pelecinidae, Gasteruptiidae, and Stephanidae The Stephanidae, sometimes called crown wasps, are a family of parasitoid wasps. They are the only living members of the superfamily Stephanoidea. Stephanidae has at least 345 living species in 11 genera. The family is considered cosmopolitan in ....

William Harris Ashmead
William Harris Ashmead was an American entomologist born on 19 September 1855 at Philadelphia. He died 17 October 1908 at Washington D.C. After his studies in Philadelphia, Ashmead worked for the publisher J. B. Lippincott & Co. Later, he settled in Florida where he formed his own publishing house devoted to agriculture. He also launched the '' Florida Dispatch'', an agricultural weekly magazine which included a headed section devoted to injurious insects. In 1879, he began writing papers for scientific publications and, in 1887, he became a field entomologist working for the Ministry for the Agriculture of Florida. The following year, he became entomologist at the Agricultural Research station of Lake City. In 1889, he worked again for the Ministry for Agriculture. The following year, and for two years, he traveled, in particular to Germany, to perfect his entomological knowledge. In 1895, he obtained the post of conservation assistant in the Department of Entomology of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ovipositor
The ovipositor is a tube-like organ used by some animals, especially insects, for the laying of eggs. In insects, an ovipositor consists of a maximum of three pairs of appendages. The details and morphology of the ovipositor vary, but typically its form is adapted to functions such as preparing a place for the egg, transmitting the egg, and then placing it properly. For most insects, the organ is used merely to attach the egg to some surface, but for many parasitic species (primarily in wasps and other Hymenoptera), it is a piercing organ as well. Some ovipositors only retract partly when not in use, and the basal part that sticks out is known as the scape, or more specifically oviscape, the word ''scape'' deriving from the Latin word '' scāpus'', meaning "stalk" or "shaft". In insects Grasshoppers use their ovipositors to force a burrow into the earth to receive the eggs. Cicadas pierce the wood of twigs with their ovipositors to insert the eggs. Sawflies slit the ...

Zootaxa
''Zootaxa'' is a peer-reviewed scientific mega journal for animal taxonomists. It is published by Magnolia Press (Auckland, New Zealand). The journal was established by Zhi-Qiang Zhang in 2001 and new issues are published multiple times a week. From 2001 to 2020, more than 60,000 new species have been described in the journal accounting for around 25% of all new taxa indexed in The Zoological Record in the last few years. Print and online versions are available. Temporary suspension from JCR The journal exhibited high levels of self-citation and its journal impact factor of 2019 was suspended from ''Journal Citation Reports'' in 2020, a sanction which hit 34 journals in total. Biologist Ross Mounce noted that high levels of self-citation may be inevitable for a journal which publishes a large share of new species classification. Later that year this decision was reversed and it was admitted that levels of self-citation are appropriate considering the large proportion of papers f ...

Fossil
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the ...
