“…4) with the software tpsDIG version 2.27 (Rohlf 2013b). Position of the landmarks was based on Owen (2012) and other studies like De Meulemeester et al (2012), Wappler et al (2012), Dewulf et al (2014), Dehon et al (2014, 2017), Gérard et al (2015), and Prokop et al (2017). The two-dimensional configurations of the landmarks were superimposed using the GLS Procrustes superimposition in the software R version 3.0.2 (Rohlf and Slice 1990; Bookstein 1991; Adams and Otárola-Castillo 2013; R Development Core Team 2013).…”

Bumble bees (Bombus spp.) are a widespread corbiculate lineage (Apinae: Corbiculata: Bombini), mostly found among temperate and alpine ecosystems. Approximately 260 species have been recognized and grouped recently into a simplified system of 15 subgenera. Most of the species are nest-building and primitively eusocial. Species of Bombus have been more intensely studied than any other lineages of bees with the exception of the honey bees. However, most bumble bee fossils are poorly described and documented, making their placement relative to other Bombus uncertain. A large portion of the known and presumed bumble bee fossils were re-examined in an attempt to better understand their affinities with extant Bombini. The taxonomic affinities of fossil specimens were re-assessed based on morphological features and previous descriptions, and for 13 specimens based on geometric morphometrics of forewing shape. None of the specimens coming from Eocene and Oligocene deposits were assigned within the contemporary shape space of any subgenus of Bombus. It is shown that Calyptapis florissantensis Cockerell, 1906 (Eocene-Oligocene boundary, Florissant shale, Colorado, USA) and Oligobombus cuspidatus Antropov, 2014 (Late Eocene, Bembridge Marls) likely belong to stem-group Bombini. Bombus anacolus Zhang, 1994, B. dilectus Zhang, 1994, B. luianus Zhang, 1990 (Middle Miocene, Shanwang Formation), as well as B. vetustus Rasnitsyn & Michener, 1991 (Miocene, Botchi Formation) are considered as species inquirenda. In the Miocene, affinities of fossils with derived subgenera of Bombus s. l. increased, and some are included in the shape space of contemporary subgenera: Cullumanobombus (i.e., B. pristinus Unger, 1867, B. randeckensis Wappler & Engel, 2012, and B. trophonius Prokop, Dehon, Michez & Engel, 2017), Melanobombus (i.e., B. cerdanyensis Dehon, De Meulemeester & Engel, 2014), and Mendacibombus (i.e., B. beskonakensis (Nel & Petrulevičius, 2003), new combination), agreeing with previous estimates of diversification.

“…In this context, geometric morphometry can be defined as a quantitative study of shape after removing the effects of scale, translation, and rotation; could be used for this purpose (Benítez and Püschel, 2014). Geometric morphometry uses multivariable statistical techniques to analyze the coordinates of landmarks based on anatomical homologous points that provide a quantifiable result of the differences in shape (Owen, 2012;Benítez and Püschel, 2014). With this tool, it is possible to discriminate and separate taxonomic groups through the shape, describing the differences using landmark displacements.…”

Native stingless bees, Meliponini, are the only social bees that produce honey in addition to honeybees. These bees have been managed in meliponiculture and for crop pollination. In Ecuador, meliponiculture studies are scarce and limited by the lack of species recognition. Traditionally the taxonomic recognition of the species is based on morphological characteristics. In Hymenoptera, the wing shape has proven to be a valuable tool in combination with traditional characters. Due to this, the wing shape was evaluated for discriminating morphospecies in Ecuador’s Amazonian meliponaries. A total of 127 specimens grouped into six genera were analyzed: Melipona (Melikerria) sp., Melipona (Michmelia) sp1., Melipona (Michmelia) sp2., Tetragonisca sp., Paratrigona sp., Nannotrigona sp., Scaura sp., and Plebeia sp. The most significant differences are located at the vein intersection: cubital and cubital 1 (Cu + Cu1), posterior margin of the marginal cell (r and Rs), and basal and posterior marginal cell (M and Rs).

Large-sized wasp, Vespa orientalis L., is a dangerous and widespread enemy to bee hives in Egypt and other countries of the world. There are eleven synonyms known as subspecies, colour forms or so called aberrations of Vespa orientalis, four of them are described from Egypt. Inadequate investigations have been used to identified these colour forms, especially depending upon colour features, without accreditation on other certainty characters such as male genitalia. Morphological with morphometric traits can help in verifying and distinguishing between the subspecies or other forms within individual species. In our study, some body structures of V. orientalis early queens, workers and drones from Egypt were measured including head length and width, mandibles length and width, antennal length, forewing length and width, hindwing length and width, number of hamuli, hind femora length, hind tibiae length and stinger. The result showed that the mean values were; queen head length 6.45 ± 0.03 and 4.54 ± 0.03 for drones, queen head width 6.97 ± 0.03, and 5.08 ± 0.04 for drones, antennal length is longer for drones 10.87 ± 0.07, slightly shorter for queens 10.08 ± 0.08, and distinctly shorter for workers 8.54 ± 0.05, forewing length 24.21 ± 0.12 for queens, and 19.89 ± 0.16 for workers, hindwing length is 14.20 ± 0.19 for queens, and 12.32 ± 0.09 for workers and drones. Some of these characters are effective to discriminating the individual species and can be utilized to emphasized the identification the original species of Vespa orientalis L.
