Neotropical Meliponini: the genus Celetrigona Moure (Hymenoptera: Apidae, Apinae)

Abstract

Three new species of Celetrigona are described: C. euclydiana sp. nov., from Acre, Brazil, C. hirsuticornis sp. nov., from Rondônia, Brazil and C. manauara sp. nov., from the northern Amazon. Additional geographic records are provided for C. longicornis (Friese, 1903), the only previously known species; its nest and the male are described and illustrated for the first time. Diagnosis and an identification key for species are provided, which are distinguished by the pattern of pilosity on the antenna.

The real taxonomic identity of Trigona latitarsis Friese, 1900, with notes on type specimens (Hymenoptera, Apidae)

“…Given that Scaura tenuis does not occur in the state of São Paulo, but only in the Amazon region from Colombia, Ecuador, Peru, Suriname, French Guiana, Bolivia and Brazil (Fig. 29), we can conclude that the locality “Saõ Paulo” written on the label of some syntypes and mentioned by Friese in the original description refers to a small town in the Amazonas State, known as “São Paulo de Olivença”, and not the state of São Paulo, as it has been interpreted since 1900 by different Meliponini taxonomists, including Silveira et al (2002), Camargo and Pedro (2002), Melo and Costa (2004), Camargo and Pedro (2013) and Oliveira et al (2013).…”

“…27A, B). For this species, Camargo and Pedro (2013) had also assumed that the type locality "S. Paulo" is in fact São Paulo de Olivença (Amazonas, Brazil), as this is an Amazonian species, and one that has never been recorded in São Paulo State (Southeastern Brazil).…”

“…The genal area is narrower than the compound eye in profile view and the malar space shorter than the diameter of the flagellum (Silveira et al 2002). The distribution of the genus is broadly Neotropical, from Mexico to southern Brazil (Camargo and Pedro 2013). …”

“…Later, Schwarz (1948) included Melipona longula Lepeletier, 1836, in this subgenus, considering it to have two subspecies (originally treated as varieties): T. (S.) longula longula and T. (S.) longula tenuis (Ducke, 1916), based on width of the hind basitarsus, the edentate mandible and the rather triangular hind tibiae. Currently, these three forms are considered distinct species (Michener 1990, Camargo and Pedro 2013, Oliveira 2016), included in Scaura as an individualized genus apart from Trigona . This interpretation was initiated by Moure (1944) when he included three species of Scaura in a list of Peruvian species.…”
