    An overlooked family-group name among bees: Availability of Coelioxoidini (Hymenoptera: Apidae)

    Get PDF
    Recent phylogenetic analysis of the family Apidae has applied the tribal name Coelioxoidini to the distinctive genus Coelioxoides Cresson, which has been thought to be related to Tetrapedia Klug.  However, the nomenclatural status of such a family-group name has not yet been assessed.  Herein, we determine that this family-group name is available and discuss its authorship and proposal date

    New host record for the enigmatic Neotropical mantidfly genus Anchieta Navás, 1909 (Neuroptera, Mantispidae), a mimic of wasps and stingless bees

    Get PDF
    Species of Symphrasinae (Neuroptera: Mantispidae) are ectoparasitoids of larvae and pupae of holometabolous insects, primarily of Hymenoptera in their larval stages. Herein we present the third case of an association between the mantidfly genus Anchieta Navás, 1909 with the order Hymenoptera. The hymenopteran species attacked by the as of yet undescribed species of Anchieta is Montezumia dimidiata Saussure, 1852 (Vespidae: Eumeninae), a predacious wasp that constructs mud nests. The association was observed in Peruvian Amazonia (near Tarapoto, San Martín), after rearing the mantidflies from a wasp nest. The biology and mimicry pattern with stingless bees of the reared Anchieta species is discussed

    A new subgenus of <i>Heterotrigona</i> from New Guinea (Hymenoptera: Apidae)

    Get PDF
    A new subgenus is established within the Indomalayan stingless bee genus Heterotrigona Schwarz (Meliponini). Sahulotrigona Engel & Rasmussen, new subgenus, is distinguished from amongst other Heterotrigona, particularly the subgenus Platytrigona Moure, within which one of the two included species was previously placed. The subgenus presently includes two species from New Guinea: Heterotrigona (Sahulotrigona) paradisaea Engel & Rasmussen, new species, and H. (S.) atricornis (Smith), new combination. A key to the subgenera of Heterotrigona is provided and the species are tabulated, resulting in the following new combinations: Heterotrigona (Platytrigona) flaviventris (Friese), H. (P.) hobbyi (Schwarz), H. (P.) keyensis (Friese), H. (P.) lamingtonia (Cockerell), H. (P.) planifrons (Smith), H. (Sundatrigona) lieftincki (Sakagami & Inoue), and H. (Su.) moorei (Schwarz). The stingless bees of Papuasia are briefly summarized, and a key is presented to the genera and subgenera of Paupasian Meliponini

    Revision of the bee genus Chlerogella (Hymenoptera: Halictidae), Part III: New records and a new species from Peru

    Get PDF
    This is the publisher's version, also available electronically from https://journals.ku.edu/index.php/melittology/indexA distinctive new species of the bee genus Chlerogella Michener (Halictinae: Augochlorini) is described and figured from central Peru (Santuario Nacional Pampa Hermosa). Chlerogella mabelae Engel, new species, is quite distinctive from other species of the genus and can be recognized by its sculpturing, coloration, and male terminalia. In addition, new Peruvian records for C. azurea (Enderlein) and C. rostrata Engel are appended

    Advances in the knowledge of quinoa pests

    Get PDF
    A wide range of quinoa pests are known throughout the world. The most serious of the Andean pests are Eurysacca melanocampta (Meyrick) and E. quinoae Povolny´ (Lepidoptera: Gelechiidae), found mainly in Peru and Bolivia, which cause considerable yield losses. Insects found elsewhere in the world are polyphagous pests constituting a wide range of potential pests if quinoa is implemented as a crop in those regions. Other major pests include a group of cutworms (Noctuidae). Apart from insects birds cause a major loss through foraging, damaging cotyledonous plants and inflorescences, with yield losses of up to 60%. Cultural practices and host plant resistances will be important components of integrated pest management (IPM). Biological control of the main pests is good; for example, up to 45% of Eurysacca melanocampta in the field are usually controlled by a range of parasitoid species as well as predators in the field. Future research should focus on the main pests in order to reveal basic information on interactions with the host plant. Population carryover from one growth season to another and the role of environmental factors on insect development and population size should also be studied
