Revisions Of Two Subgenera Of Andrena: Micrandrena Ashmead And Derandrena, New Subgenus (Hymenoptera: Apoidea), David O. Ribble
Revisions Of Two Subgenera Of Andrena: Micrandrena Ashmead And Derandrena, New Subgenus (Hymenoptera: Apoidea), David O. Ribble
Bulletin of the University of Nebraska State Museum
This paper is a monographic revision of the bee subgenera Micrandrena Ashmead and Derandrena, new subgenus, of the genus Andrena in North America. Both subgenera occur in the New World and Micrandrena also occurs in the Old World. Twenty-eight species are treated, of which twelve are new: Andrena (Micrandrena) annectens, ishii, labergei, lamelliterga, lepidii, micheneri, Andrena (Derandrena) arctostaphylae, californiensis, hermosa, murietae, penutiani, viridissima. Thirteen names are placed in synonymy: Andrena semotula Cockerell with candidiformis Viereck and Cockerell; subtilicornis Viereck, nitidicornis Cockerell, chlorogaster nesiotes Timberlake, chlorogaster gavilanica Timberlake, radialis Timberlake, catalinica Cockerell with chlorogaster Viereck; vegana Viereck and Cockerell with illinoiensis …

Bulletin of the University of Nebraska State Museum
The genus Hemipterodectes Berla is redefined and the type species, H. squalocauda is figured. A new genus, Diproctophyllodes (type species, Proctophyllodes (Alloptes) dielytra Trouessert, 1885) is described; D. exquisita (Berla), 1959 is synomized with D. dielytra; and D. oxyrunci, new species, is described.
Biometrical Study Of Morphology And Development Of The Pennsylvanian Trilobite Ameura Sangamonensis (Meek And Worthen), Roger K. Pabian, J. A. Fagerstrom
Biometrical Study Of Morphology And Development Of The Pennsylvanian Trilobite Ameura Sangamonensis (Meek And Worthen), Roger K. Pabian, J. A. Fagerstrom
Bulletin of the University of Nebraska State Museum
Biometrical study of morphology and development in a sample of 100 cranidia, 94 pygidia, 26 free cheeks, and 9 complete specimens of the trilobite Ameura sangamonensis (Meek and Worthen) from the Bonner Springs Shale (Pennsylvanian; Missouri Series) in eastern Nebraska indicates that the dominant growth pattern was isometric. Evidence supporting this conclusion consists of rectilinear size relations among eight pairs of cranidial dimensions, three pairs of pygidial dimensions, and three pairs of dimensions of the free cheeks. Qualitative changes in pygidial morphology during development include a progressive decrease in prominence of the border, increasing width of the posterior border relative …

Bulletin of the University of Nebraska State Museum
Five new genera are described; these and the included species are (type species listed first): Dichobrephosceles with Dermaleichus actitidis Canestrini, 1878 (=Brephosceles dolichocaulus Gaud and Mouchet, 1957, new synonymy), D. eroliae, new species (ex: Erolia alpina, England); Homeobrephosceles with Proctophyllodes (A lloptes) discosurus Trouessart, 1886, Brephosceles orthothrix Gaud and Mouchet, 1957; Onychalloptes with Proctophyllodes (Alloptes) microphaeton Trouessart, 1885, Alloptes minutus Trouessart, 1899; Aramolichus with Aramolichus foliatus, new species (ex: Aramus guarauna, Bolivia); Psilobrephosceles with Dermalichus ortygometrae Canestrini, 1878. Species included in the genus Brephosceles (s.s.) are listed; species transferred to Brephosceles are: Proctophyllodes (Pterocolus) fiagellifer discursus Trouessart, 1885; Pterocolus lambda …

Bulletin of the University of Nebraska State Museum
A systematic study of the acarine subfamily Trouessartinae (except Trouessartia) of the family Proctophyllodidae is presented. Diagnoses are given for the subfamily, five named genera and four new genera. The named genera and their type species are: Allanalges Trouessart, 1886, A. podagricus (Trouessart), 1886; Calcealges Gaud, 1952, C. cyathoplax Gaud, 1952; Hemicalcealges Gaud and Mouchet, 1957, H. margaropygus (Gaud and Mouchet), 1957; Pseudalges Radford, 1950, Proctophyllodes (Pterocolus) analgoides Trouessart, 1885; and Trouessartia Canestrini, 1899, Dermaleichus corvinus Koch, 1840. New genera and their type species are: Arthrogynalges, A. biovoidatus, new species; Bicentralges, B. orientalis, new species; Neocalcealges, N. inattditus, new species; …
