متن کاملA formicine in New Jersey cretaceous amber (Hymenoptera: formicidae) and early evolution of the ants.
A worker ant preserved with microscopic detail has been discovered in Turonian-aged New Jersey amber [ca. 92 mega-annum (Ma)]. The apex of the gaster has an acidopore and, thus, allows definitive assignment of the fossil to the large extant subfamily Formicinae, members of which use a defensive spray of formic acid. This specimen is the only Cretaceous record of the subfamily, and only two othe...
متن کاملCretevania bechlyi sp. nov., from Cretaceous Burmese amber (Hymenoptera: Evaniidae).
The fossil evaniid wasp Cretevania bechlyi sp. nov., is described based on a well preserved female specimen from Cretaceous Burmese amber. The new species is placed in the genus Cretevania Rasnitsyn, 1975 based on the elongation of the mid and hind trochantellus, the fore wing venation (e.g. first marginal cell triangular and broad, 2m-cu absent, second sub-marginal cell separated from first di...
متن کاملHymenoptera: Vespidae)
Workers in many insect societies interact via body contact with their nest mates, and social biting and other forms of contact may play a general role in regulating task performance. Here I present evidence that social biting affects task performance without direct reproductive conflict in Polybia occidentalis, a swarm-founding eusocial wasp. Polybia occidentalis workers engaged in social bitin...
متن کاملA new genus of fossil Mymaridae (Hymenoptera) from Cretaceous amber and key to Cretaceous mymarid genera
Myanmymar aresconoidesgen n., sp. n. is described from one female in Burmese amber, dated as about 100 my. It is similar to Arescon on wing features but is unique among Mymaridae in having distinctly segmented palpi. It is the fifth mymarid genus definitely referable to the Cretaceous period. A key to Cretaceous mymarid genera is presented and the features of Myanmymar are compared with the oth...
