A NEW SPECIES OF PAPER WASP FROM COSTA RICA (HYMENOPTERA: VESPIDAE; POLISTINAE, EPIPONINI)
Journal of the New York Entomological Society, 2002Abstract.-Polybia selvana, a new species of paper wasp from Costa Rica, is described. The social wasp genus Polybia is the one of the largest and most commonly encountered paper wasp genera in the Neotropics. Presently, there are 58 species recognized, with another 19 subspecies (Richards, 1978; Cooper, 1993; Carpenter et al., 2000; Raw, 2000).

In the Epiponini, queen number may vary from many to few during the colonial cycle. This cyclical oligogyny may be important for the maintenance of high genetic relatedness found in several taxa of epiponines. Even though queen reduction in accord with the colony cycle has either been demonstrated or inferred for many taxa, the factors responsible for ...

AbstractThe thermal characteristics of a colony of Apoica flavissima, an epiponine wasp, were examined. The nest, with a diameter of slightly less than 30 cm, was built on a twig of an orange tree. The temperature of the roof surface fluctuated greatly, ranging between 19.1 and 41.5°C.

In neotropical swarm-founding wasps, caste differences can be arranged along a spectrum ranging from taxa in which queens and workers are externally similar, to others with fairly distinct caste attributes. In this study, queen-worker differences progressively increase during colony development in Protopolybia exigua and Chartergus globiventris.
