“…That decision should await a more rigorous study of the speciose Plebeia ‐like group. To enforce monophyletic taxa, the genus Schwarzula should be synonymized under Scaura , sensu Michener (1990), and Dolichotrigona should be synonymized under Trigonisca , sensu Camargo & Pedro (2005). The revised morphological diagnosis for Scaura follows Moure (1951: 51) and that for Trigonisca follows Camargo & Pedro (2005: 70).…”

Stingless bees (Meliponini) are one of only two highly eusocial bees, the other being the well studied honey bee (Apini). Unlike Apini, with only 11 species in the single genus Apis, stingless bees are a large and diverse taxon comprising some 60 genera, many of which are poorly known. This is the first attempt to infer a phylogeny of the group that includes the world fauna and extensive molecular data. Understanding the evolutionary relationships of these bees would provide a basis for behavioural studies within an evolutionary framework, illuminating the origins of complex social behaviour, such as the employment of dance and sound to communicate the location of food or shelter. In addition to a global phylogeny, we also provide estimates of divergence times and ancestral biogeograhic distributions of the major groups. Bayesian and maximum likelihood analyses strongly support a principal division of Meliponini into Old and New World groups, with the Afrotropical+Indo-Malay/Australian clades comprising the sister group to the large Neotropical clade. The meliponine crown clade is inferred to be of late Gondwanan origin (approximately 80 Mya), undergoing radiations in the Afrotropical and Indo-Malayan/ Australasian regions, approximately 50-60 Mya. In the New World, major diversifications occurred approximately 30-40 Mya.

“…Thus, the amber samples were set aside as unworkable in terms of their taxonomic value, whereas the bee was successfully extracted from the copal and identified as a new species, following dissection in alcohol under a stereomicroscope.

Amber and copal are renowned for preserving insects and other inclusions with lifelike fidelity. However, due to their frozenin-time nature, they are taxonomically subequal to Recent insects, which commonly require dissection in order to identify them to species level. This can be overcome to a degree through digital dissection using computed tomography, but this technique is time consuming, expensive, and not widely accessible. We attempted to dissolve inclusions out of Dominican and Baltic ambers and Quaternary Colombian copal using chloroform. Extraction of specimens from amber was unsuccessful, but we were able to extract a stingless bee from the less polymerized copal and dissect it under a microscope as if it were a recently caught insect. We were able to examine all of the features that are considered to be diagnostic for extant species, and thus our subfossil is taxonomically equivalent to a living species. The copal bee is a new species of the Trigonisca longitarsis species group (=Dolichot-rigona), which is described and figured herein as Trigonisca ameliae n. sp. (Hymenoptera: Apidae). The ability to extract inclusions from (sub)fossil resins facilitates more accurate studies of Quaternary tropical forest biodiversity, in addition to molecular paleobiology and taphonomic physiochemical changes resulting from diagenetic processes following entombment in copal-and amber-forming resins. Colombian copal is radiocarbon dated within the age range <60 (postbomb) to 10,612 ± 62 years old.

“…In G. subterranea the period of maximum activity coincides with the high temperature time during the day. Despite having black color, this species is small (5.80 mm long (Camargo & Moure, 1996)), an important feature, since smaller Meliponini species suffer less restrictions at warmer periods, compared to larger species (Roubik, 1993).…”

“…However, to date, few studies have addressing these issues in subterranean stingless bees. Geotrigona subterranea occurs in the Brazilian states of Bahia, Minas Gerais, Paraná and São Paulo (Camargo & Moure, 1996). Its nest is built in subterranean cavities of various types, usually abandoned nests of ants and termites.…”

Flight activity of bees is influenced both by environmental factors and by internal condition of the colonies. Information about external activity of bees is very important, because it provides data of the species biology, supplying subsidies for the use of these insects in the pollination of crops. The present work aim to evaluate the flight activity of Geotrigona subterranea (Friese, 1901) (Hymenoptera: Apidae) in natural environment. This study was performed on the Instituto Federal do Norte de Minas Gerais, in the municipality Januária, Minas Gerais State. Two natural nests were observed. The activities of bees of the colonies were recorded three days each month, during the period of December 2011 to November 2012, totaling 924 observations. It was recorded the number of bees leaving and entering the nest, and the type of material transported by them for ten minutes each hour from 5 a.m. to 7 p.m. The bees entered the colony carrying pollen, resin, detritus and also without apparent material. The bees began external activities by 6 a.m. at 20°C and finished at 6 p.m. at 28.8°C. The peak of activity of G. subterranea occurs on schedule from 1 to 2 p.m. Even though G. subterranea makes their nests in underground, their foraging activities are very similar to others stingless bee species that usually nest on tree cavities or aerial places. This indicate that despite their particular nesting way the external factors as climatic ones will significantly modulate their foraging pattern in a daily and seasonal way.
