Notes on social wasps of the group of Mischocyttarus (Omega) punctatus (Ducke), with description of six new species (Hymenoptera, Vespidae, Polistinae)

Nest camouflage records on five social wasp species (Vespidae, Polistinae) from southeastern Brazil

“…Considering behavioral aspects for more aggressive species, the stinger appears to be sufficient; however, docile species usually adopt other strategies, such as Parachartergus colobopterus (Lichtenstein), which uses camouflage to defend its colonies (strassMann et al 1990). This is also true for Mischocyttarus species (riChards 1978;Giannotti 1999;siLveira et al 2015), and other genera such as Nectarinella (WenzeL 1998) and Leipomeles according to (starr, 1991). Active searches for colonies were carried out between 9 am and 4 pm.…”

New records of Vespidae (Hymenoptera: Vespoidea) for the Colombian Orinoco Region

“…Images were merged using CombineZP software. Taxonomic identification to Biota ColomBiana 20 (1) -2019 ┃ genus and species levels was made according to literature for Neotropical Vespidae (Richards, 1978;Carpenter, 2004;Picket & Wenzel, 2007;Silveira, 2008;Andena et al, 2009;Silveira et al, 2015;Santos Júnior et al, 2015, 2017. The species' occurrence in CEO was compared with the information reported by literature on social wasps for Colombia (e.g.…”

Keys to the Costa Rican species of paper wasps (Hymenoptera: Vespidae: Polistinae)

“…Literature sources included Richards (1978) and subsequent descriptions of new species: Mischocyttarus pelor (Carpenter & Wenzel, 1988), Agelaia melanopyga and A. pleuralis (Cooper, 2000), Chartergellus golfitensis (West-Eberhard, Carpenter, Gelin, & Noll, 2010), Metapolybia mesoamerica (Smethurst & Carpenter, 1997), M. servilis (Cooper, 1999), Polybia selvana (Carpenter & Kojima, 2002) and Protopolybia collombiana (Dos Santos Junior, Silveira, & Carpenter, 2015). There have also been a few changes in species-level nomenclature (Snelling, 1983;Carpenter, 1999Carpenter, , 2012Silveira, 2006;Silveira, Silva, & Felizardo, 2015). Specimens were examined based on collections in the American Museum of Natural History, the Zoology Museum of the University of Costa Rica, and the National Museum of Costa Rica (formerly INBio).…”
