Item Egg and mature larva of a species of Plebeia with a preliminary overview of the mature larvae of the Meliponini relative to those of other corbiculate taxa (Apoidea, Apidae). (American Museum novitates, no. 3940)(American Museum of Natural History., 2019-09-27) Rozen, Jerome G., Jr. (Jerome George), 1928-; Smith, Corey Shepard.; Roubik, David W. (David Ward), 1951-The egg and mature larva of a presently unnamed species of the bee genus Plebeia are anatomically described, illustrated, and compared with those of other known Meliponini, based on abundant specimens collected from two nests recovered from a tree at the Yasuní Scientific Station, Orellana Province, Ecuador. A key to the four tribes (Apini, Bombini, Euglossini, and Meliponini) of known mature corbiculate larvae is then presented. It, in turn, is followed by a preliminary larval description of the Meliponini based on those taxa the mature larvae of which are known so far. The main feature distinguishing the mature larva of the Meliponini is in its having a tapering slender elongate mandibular apex, which contrasts with the much shorter, robust mandibular apex of the other three tribes. Furthermore, unlike in the other tribes, late stage larval Meliponini possess paired dorsolateral tubercles on most abdominal segments.Item Immature stages of selected meliponine bees (Apoidea, Apidae). (American Museum novitates, no. 3924)(American Museum of Natural History., 2019-04-08) Rozen, Jerome G., Jr. (Jerome George), 1928-; Quezada Euán, José Javier G.; Roubik, David W. (David Ward), 1951-; Smith, Corey Shepard.This paper describes the eggs and last larval instars of certain species of bees belonging to the tribe Meliponini, one of the four related tribes that comprise the corbiculate bees in the subfamily Apinae. The four taxa analyzed include some whose immature stages have previously been described. Our purpose is to identify what is known about the anatomy of immature stages and suggest what needs to be studied to better understand the developmental anatomy of eggs and mature larvae in this group of highly eusocial bees.
