Item Allodapine bees in the Arabian Peninsula (Hymenoptera, Apidae) : a new species of Braunsapis from the Sarawat Mountains, with an overview of the Arabian fauna. (American Museum novitates, no. 3801)(American Museum of Natural History., 2014-04-29) Engel, Michael S.; Alqarni, Abdulaziz S.; Hannan, Mohammed A.; Hinojosa-Díaz, Ismael A.; Michener, Charles D. (Charles Duncan), 1918-2015.An interesting new species of allodapine bee (Xylocopinae: Allodapini: Allodapina) is described and figured from males and females captured in the Sarawat Mountains near al-Baha, representing the first records of the tribe for Saudi Arabia. Braunsapis alqarnii Engel and Michener, new species, is similar to the small species of the genus known from Africa and Madagascar but is distinguished on the basis of several features, most notably the male hind legs and terminalia. Notes are provided on the known allodapine fauna of the Arabian Peninsula, with a key to the species.Item Allodapine bees of Madagascar (Hymenoptera, Apoidea). American Museum novitates ; no. 2622(New York, N.Y. : American Museum of Natural History, 1977) Michener, Charles D. (Charles Duncan), 1918-2015."This is a taxonomic revision of Malagassy allodapine bees, with keys, descriptions, and illustrations. At least 13 species are known, seven of which (Braunsapis madecassella, Effractapis furax, Allodapula rufa and platyprosopon, Halterapis kraussi and tulearensis, and Macrogalea infernalis) are described as new and one, whose name was preoccupied, is provided with a new name (Allodapula benoisti). Outstanding among the findings are (1) a new parasitic genus, Effractapis, allied to and presumably parasitic upon Braunsapis; (2) distinctive groups of species tentatively placed in Halterapis and Allodapula but not closely related to other species of these South African genera; and (3) species of Braunsapis and Macrogalea closely related to African members of these genera"--P. [1].Item Bees of Panamá. Bulletin of the AMNH ; v. 104, article 1(New York : [American Museum of Natural History], 1954) Michener, Charles D. (Charles Duncan), 1918-2015.Item Biologies of African allodapine bees (Hymenoptera, Xylocopinae). Bulletin of the AMNH ; v. 145, article 3(New York : [American Museum of Natural History], 1971) Michener, Charles D. (Charles Duncan), 1918-2015."A few allodapine bees (genus Halterapis) mass provision their nests, but most feed their larvae progressively. The structure and behavior of larvae and pupae enables them to maintain their positions in the hollow stems in which they live. In common genera such as Braunsapis and Allodape, the arrangement is from youngest below to oldest above. Each larva in these genera is fed by means of provisions placed on its venter by adult bees. In the genus Allodapula, however, larvae are together in a clump instead of one above another and feed from a common food mass. Such matters as positions of eggs, larvae, and pupae, and ways in which larvae are fed, are summarized in the preliminary account of each genus and in the section entitled Allodapine Biology. In the Conclusions are found comments on which of the physiological or behavior characteristics are ancestral and which derived. Social behavior of allodapines is treated both in the Species Accounts and the section on Allodapine Biology. The allodapines are noteworthy for the small sizes of the populations of adults in their colonies and the failure of many nests, even of the more social species, to acquire workers at all. They range from simple subsocial species in which each nest normally contains only a single bee and additional mature adult females are rare and seem almost accidental, to those in which nearly 40 per cent of the nests contain two or more mature adult females. Even in the small and facultative groups of adult females, weak polymorphism arises. This is shown behaviorally in that certain females (workers) do most of the foraging, others (queens) do little foraging when workers are present. The workers often do not mate. Many workers, unlike queens, do not experience much ovarian development, although others do and probably lay some eggs. There is meager evidence that workers are short lived compared to queens. In some species the mean size of workers is less than that of queens. In all these features (except, of course, mating) intermediacy is common and many bees can be placed as to caste only arbitrarily. In an Appendix preliminary descriptions are given for eleven new species falling in the genera Allodape, Braunsapis, Allodapula, and Exoneurula in order to validate names for forms on which biological information is presented"--P. 294.Item The biology of Scrapter and its cuckoo bee, Pseudodichroa (Hymenoptera, Colletidae and Anthophoridae). American Museum novitates ; no. 2335(New York, N.Y. : American Museum of Natural History, 1968) Rozen, Jerome G., Jr. (Jerome George), 1928-; Michener, Charles D.

Bulletin of the AMNH ; v. 130(New York : [American Museum of Natural History], 1965) Michener, Charles D. (Charles Duncan), 1918-2015.Item Comparative external morphology, phylogeny, and a classification of the bees (Hymenoptera). Bulletin of the AMNH ; v. 82, article 6(New York : [American Museum of Natural History], 1944) Michener, Charles D. (Charles Duncan), 1918-2015.Item An exomalopsine bee in early Miocene amber from the Dominican Republic (Hymenoptera, Apidae). (American Museum novitates, no. 3758)(American Museum of Natural History., 2012-09-14) Engel, Michael S.; Grimaldi, David A.; González, Víctor H.; Hinojosa-Díaz, Ismael A.; Michener, Charles D. (Charles Duncan), 1918-2015.The first fossil exomalopsine bee is described and figured from two females, one very partially preserved in early Miocene amber from the Dominican Republic. Anthophorula (Anthophorula) persephone Engel, new species, is distinguished from its modern counterparts mainly by the broader pterostigma in which its inner breadth is greater than that of its marginal veins. This record expands the Dominican amber melittofauna to 21 species. Brief comments are made on the discovery as well as the Dominican amber bees in general. The new combination Thaumatosoma (Chalicodomopsis) glaesaria (Engel) is established.Item The generic classification of the anthidiine bees (Hymenoptera, Megachilidae).

American Museum novitates ; no. 2693(New York, N.Y. : American Museum of Natural History, 1980) Michener, Charles D. (Charles Duncan), 1918-2015."Several species of Homalictus and the related genus Urohalictus are markedly larger than other Homalictus. All these large species (all but one of which are new) occur at moderate to high altitudes in New Guinea or nearby islands, regions where other moderate-sized to large Halictinae are almost absent except for Lasioglossum (Parasphecodes?) permetallicum Michener. Five related new species (Homalictus megalochilus, H. torulosus, H. pelorodontus, H. umbonis, and H. sedlaceki) constitute the new subgenus Papualictus. The other large forms of Homalictus seem to have been independently derived, presumably from different small ancestors. Such large species are H. tricolor Michener and the new species H. hirashimai and H. ocellaris. Urohalictus lieftincki, new species, is an extraordinary bee related to Homalictus and Lasioglossum; it is possibly parasitic although one cannot be certain of this in the ansence of females"--P. [1].Item Nests and immature stages of the bee Paratetrapedia swainsonae (Hymenoptera, Anthophoridae).

American Museum novitates ; no. 3281(New York, NY : American Museum of Natural History, 1999) Michener, Charles D. (Charles Duncan), 1918-2015.; Rozen, Jerome G., Jr. (Jerome George), 1928-"A new genus of the bee subfamily Xeromelissinae from Argentina is proposed as Geodiscelis (type species, Geodiscelis megacephala, new species). Geodiscelis possesses a mixture of characters from both of the previously recognized tribes of Xeromelissinae. The tribes Chilicolini and Xeromelissini therefore merge and are no longer recognized, the five genera being united in the subfamily without tribal classification. Prior reports of nests of xeromelissines describe series of cells in burrows in stems or abondoned burrows of beetles in twigs. Geodiscelis, however, nests in loose sand, and cells are isolated at the ends of lateral burrows. It is a probable specialist visitor to flowers of Heliotropium, and its unusual glossa may be related to use of this floral resource"--P. [1].Item New neotropical saturnioid moths (Lepidoptera).

(American Museum novitates, no. 3886)(American Museum of Natural History., 2017-12-06) Engel, Michael S.; Michener, Charles D. (Charles Duncan), 1918-2015.; Boontop, Yuvarin.A new species of stingless bee (Apinae: Meliponini) is described from workers and two males recovered from nests in tree trunks in Kanchanaburi Province, Thailand. Tetragonula (Tetragonula) malaipanae, new species, resembles T. (T.) laeviceps (Smith), T. (T.) pagdeni (Schwarz), T. (T.) testaceitarsis (Cameron), and similar species, but is particularly similar to T. (T.) drescheri (Schwarz). Unlike T. drescheri, the new species lacks a defined black stripe on the underside of the metafemur, has the metatibia reddish brown to testaceous (rather than uniformly chestnut brown, and black with a yellow mark on the inner surface in T. drescheri). Characters of the uncommonly encountered T. (T.) sarawakensis (Schwarz) are also recorded.Item Observations on the behavior of Brazilian halictid bees (Hymenoptera, Apoidea). 4, Augochloropsis, with notes on extralimital forms.

American Museum novitates ; no.2026(New York, N.Y. : American Museum of Natural History, 1961) Michener, Charles D. (Charles Duncan), 1918-2015."The nests of meliponine bees exhibit many features of phyletic and adaptive significance. These characters, which of course result from the behavior of the numerous workers in the colonies, should be considered in conjunction with morphological features and other behavioral ones in assessing the relationships of species of this tribe. Homologies of nest parts are discussed, and a terminology for them is presented. Failure to formalize such matters in the past has resulted in the confused use of the word 'involucrum' for two different structures in different species. The nests of seven species of Trigona from Australia and New Guinea are described. The nests of those species of the subgenus Plebeia that were studied (australis and cincta) differ from other known meliponine nests in having spherical cells which open in various directions, not necessarily upward; from those of other species in which the cells are arranged in clusters, these differ in the presence of an involucrum consisting of a single cerumen sheet. Possibly these features are primitive. It seems reasonably clear that the cluster arrangement of cells found in other species, and considered primitive by previous authors, is in reality an adaptation (associated with loss of the involucrum) making possible the use of small and irregular cavities for nesting places. One species (T. hockingsi) arranges its cells in a manner intermediate between combs and clusters. Reports that two species of Australian Trigona (australis and carbonaria) leave the brood cells open and add provisions to them until as much as three days after hatching of the larvae could not be verified and presumably have no basis in fact. These Australian bees, as do all other Trigona species, mass provision their cells. The establishment of new colonies was not observed, but flights of males and other activities indicate that it must be similar to that of South American stingless bees"--P. 44-45.
