Biology of the bee genus Conanthalictus (Halictidae, Dufoureinae). American Museum novitates ; no. 2602

6 p. : ill. ; 26 cm.Includes bibliographical references (p. 6)."The following details of the nesting biology of Conanthalictus (Sphecodosoma) dicksoni Timberlake and C.(C.) conanthi (Cockerell) are given and where possible are compared and contrasted with the biologies of Dufourea and the other dufoureines: choice of nesting site, number of females to a nest, nest description, pollen plant preference, provisioning habits, appearance of eggs and larvae, feeding activities of larvae, cocoon construction and appearance, number of generations per year, adult activities, and nest associates. The Dufoureinae appears to be a homogeneous and distinctive taxon in terms of its nesting habits"--P. [1]

Ammobatine bees

16 p. : ill. ; 26 cm.Includes bibliographical references (p. 16)."Mature larvae of representatives of four genera of the Ammobatini are taxonomically described--Pseudodichroa, Ammobates, Morgania, and Oreopasites. A key is provided for their identification and the tribe is characterized on the basis of the mature larvae. Pupae of representatives of two genera are described--Oreopasites and Morgania. A preliminary key to the pupae of the subfamily Nomadinae is also presented"--P. 3

Biology and larvae of the cleptoparasitic bee Townsendiella pulchra and nesting biology of its host Hesperapis larreae (Hymenoptera, Apoidea). American Museum novitates ; no. 3005

11 p. : ill. ; 26 cm.Includes bibliographical references (p. 11

Nesting biology, immature stages, and phylogenetic placement of the Palaearctic bee Pararhophites (Hymenoptera, Apoidea). American Museum novitates ; no. 2903

21 p. : ill. ; 26 cm.Includes bibliographical references (p. 20-21)."The following subjects are described for the bee Pararhophites orobinus (Morawetz) from Pakistan: nest architecture, egg deposition, development, larval behavior, cocoon construction, floral relationships, and nest provisions. The authors present a cladistic analysis of the phylogenetic relationships of Pararhophites with other taxa of long-tongued bees using characters of nesting biology and of larval and adult anatomy. The authors agree that Pararhophites probably belongs to the megachilid lineage rather than to the anthophorid/apid line where it has been assigned in the past. McGinley does not make a formal transfer of the genus now because of the unsettled relationships of the families of long-tongued bees; Rozen places Pararhophites in the subfamily Pararhophitinae and places it in the Megachilidae (new subfamily, new placement)"--P.
