The chrysomelid genus Dibolia Latr. is revised for North America north of Mexico. Thirteen species are recognized, 6 of which are described as new: D. californica, D. chelones, D. kansana, D. melampyri, D. obscura, and D. penstemonis. Dibolia championi Jacoby is recorded for the first time from the United States and Mexico.All species are described and illustrated, host plant records are provided where possible, and a key for the separation of the species is presented. The distribution of each species is indicated by locality records and distribution maps. A general discussion of the habits of the genus, a brief redescription of the larva of D. borealis Chev., and a brief review of the habits of this species are also included.

As a contribution to our knowledge of diatom biodiversity and biogeography in the United States, high resolution light microscope images are provided for 139 diatom taxa recorded from lake, stream, spring and glacier habitats in Wrangell-St. Elias National Park, Alaska. The spring had the highest taxa richness of the four habitats that were sampled, likely owing to the relative stability of this habitat compared to the others. Most of the taxa were described from northern and alpine locations in Europe and North America and are typical of habitats in the northern Rocky Mountains, with two notable exceptions. Surirellaarctica had been reported previously only from locations in the High Arctic of North America, north of 68°N latitude. Gomphonemacaperatum has a disjunct distribution in montane regions of the eastern and far western contiguous United States. This may be the first record of this taxon from Alaska.

Herein, the cleptoparasitic (cuckoo) bee genusEpeolus(Hymenoptera: Apidae) is revised for species occurring in North America, north of Mexico, and an updated checklist of all species known to occur in Canada and the United States of America is provided with comprehensive descriptions, diagnoses, and a single dichotomous key (using the same couplets for both sexes) to aid in their identification. To increase their recognition among North American naturalists, English common names are also proposed for all North AmericanEpeolus. A total of 43 species is confirmed as present in the region, 15 of which are newly recognized. The following new species are proposed based on unique morphological (and in most cases also molecular) attributes:E.andriyisp. n.,E.attenboroughisp. n.,E.axillarissp. n.,E.basilisp. n.,E.brumleyisp. n.,E.chamaesarachaesp. n.,E.deyrupisp. n.,E.diadematussp. n.,E.ferrariisp. n.,E.gibbsisp. n.,E.inornatussp. n.,E.nebulosussp. n.,E.packerisp. n.,E.splendidussp. n., andE.tessierissp. n.Of the 15, six (E.axillaris,E.brumleyi,E.chamaesarachae,E.diadematus,E.splendidus, andE.tessieris) were identified as new species under different names (nomina nuda) in an M.Sc. thesis by Richard L. Brumley in 1965, but until now they have not been formally described. Detailed morphological comparisons with some evidence from DNA barcoding support the following synonymies, one of whichCwas first proposed by Brumley (1965): a)E.melectimimusCockerell and Sandhouse,syn.n., underE.asperatusCockerell; b)E.crucisCockerell,syn.n., underE.compactusCresson; c)E.mesillaepalmarumLinsley,syn.n., underE.mesillae(Cockerell); and d)E.weemsiMitchell,syn.n., and e)E.vernalisMitchell,syn.n., underE.ilicisMitchell. Only one member of the almost entirely Neotropical “Trophocleptria group” (EpeolusbifasciatusCresson) is confirmed as occurring north of Mexico, and is widespread East of the Rocky Mountains. Known floral associations are indicated for each species, as are suspected or known host species ofColletesLatreille. Evidence is presented that suggests further investigation into the possible synonymy ofColleteswickhamiTimberlake underC.scopiventerSwenk is warranted.

AbstractThe two subgenera and 20 species of the crab spider genus Ebo in North America north of Mexico are described or redescribed, keyed, and illustrated. The subgenus Ebo contains seven species, of which E. iviei, E. evansae, E. contrasts, and E. punctatus are described as new and the female of E. merkeli Schick is described for the first time. The subgenus Titanebo contains 13 species, of which E. cantralli is described as new and the female of E. texanus is described for the first time.
