A revision of the Neotropical eumenine wasp genus Stenosigma Giordani Soika, 1978 (Hymenoptera, Vespidae)

Abstract

The Neotropical eumenine wasp genus Stenosigma Giordani Soika, 1978 is revised. Stenosigma mariae Ferreira & Hermes sp. nov. and S. panamensis Ferreira & Hermes sp. nov. are proposed as new. An updated identification key for species, new distributional records, and additional information on the species currently recognized within the genus are presented.

The Eumeninae (Hymenoptera, Vespidae) of Hong Kong (China), with description of two new species, two new synonymies and a key to the known taxa

“…The Eumeninae are all solitary wasps, although some species display behaviours that are considered precursors of eusociality in Vespidae, such as communal nesting and progressive provisioning of food for the brood. The subfamily contains about 3800 valid species worldwide, in 204 extant genera (Carpenter 1986;Yamane 1990;Zhou et al 2011;Tan et al 2018;Pannure et al 2016;Ferreira et al 2018;Li and Carpenter 2018;Selis 2018;Carpenter unpubl.). They are usually predators of Lepidoptera or Coleoptera larvae, although predation on larvae of sawflies is also recorded.…”
