The Aleiodes pallidator species-group is defined, and an identification key is provided for the five species known to occur in the U.S.A. and Canada. Two new species are described: Aleiodes martini Shaw and Marsh, from Florida, and A. xanthoclypeus Shaw and Marsh, known from Canada and Wisconsin, and reared from Lymantriidae species including Dasychira plagiata (Walker) and Olene grisefacta (a new host record for the genus Aleiodes). Five species are illustrated, and their host associations are summarized.

AbstractThe species of the genus Entomacis Foerster in North America north of Mexico are revised. Nineteen species (12 new), including 8 species of the Holarctic-wide perplexa species group, are keyed, described, and figured. These taxa are E. ambigua (Brues), E. apopkaensissp. nov., E. arcticasp. nov., E. cellariasp. nov., E. cepasp. nov., E. eorariasp. nov., E. floridana (Ashmead), E. grandiclavasp. nov., E. longii (Ashmead), E. mellipetiola (Ashmead), E. parambiguasp. nov., and perplexa group members E. californica (Ashmead), E. microbipunctatasp. nov., E. notioxerasp. nov., E. oulasp. nov., E. parvasp. nov., E. perplexa (Haliday), E. sapratasp. nov., and E. subemarginata (Ashmead). Hemilexodes canadensis (Harrington) is synonymized under Entomacis mellipetiola (Ashmead) (syn. nov.). The status of Entomacis latipennis (Ashmead), E. filiformis (Ashmead), and Hemilexis jessei Mann is reviewed. New character complexes, particularly chaetotaxy, are emphasized for Diapriidae species taxonomy.

Species of North American Cybaeus L. Koch (Araneae: Dictynoidea: Cybaeidae) are common moist-forest spiders classified in Holarctic and Californian clades. Here we review the adenes species group of the Californian clade. We recognize nine species: Cybaeus adenes Chamberlin & Ivie, C. amicus Chamberlin & Ivie, C. auburn Bennett spec. nov., C. grizzlyi Schenkel, C. pearcei Bennett spec. nov., C. reducens Chamberlin & Ivie, C. sanbruno Bennett, C. schusteri Bennett spec. nov., and C. torosus Bennett spec. nov. The species of the adenes group have extremely restricted ranges in west central California from Sonoma and Napa Counties south to northern Monterey County and in east central California from Placer and El Dorado Counties. Descriptions, illustrations, range maps, and an identification key are provided for all species.

Karyological Data

The amphiatlantic distribution of the genus Planaria is incompatible with our current hypothesis of the historical biogeography of freshwater planarians. New anatomical studies suggest the possibility that the genus is not strictly monophyletic; new karyological data are strongly corroborative of that conclusion. The karyotypes of the American species of Planaria are almost identical with those of many other North American Planariidae and quite distinct from that of the European species. These findings are inconsistent with the hypothesis that the species of Planaria form a strictly monophyletic group. Therefore the amphiatlantic disjunction is apparent, not real, and the earlier biogeographical hypothesis is protected from one potential falsifier.
