AbstractThe genera Haida Keen and Pseudohaida Hatch are revised and transferred from the tribe Coryphiini to the Anthophagini; the Palearctic genus Eudectus Redten bacher is also placed in the Anthophagini. Eudectus crassicornis LeConte is transferred to the new gents Eudectoides. Two new species are described, Haida bisulcata from the Sierra Nevada in California and H. insulcata from Oregon. Pseudohaida ingrata Hatch is transferred to Subhaida Hatch, a member of the tribe Coryphiini.The mouthparts and antenna are illustrated for each genus and the male aedeagus for each species. A key is included to aid in the identification of all the included taxa.

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.

The Individual

The results are given of a survey of the cestode fauna of several thousand fishes representing thirty species common in the Hudson bay drainage system, particularly in the Hudson bay and in the larger lakes of Manitoba and Saskatchewan. The survey yielded twelve species of adult and seven species of larval cestodes, ten of which were identical with European species, while seven were purely North American. The incidence of infection was high and the individual intensity was heavy. The highest incidence and heaviest intensity occurred among nektonic types such as Hiodon, Leucichthys, Esox, Lucioperca and Salvelinus. Benthonic forms such as Catostomus, Ameiurus, Lota, Acipenser and Coregonus, were found relatively free from infection.The North American species of Cyathocephalus and Diplocotyle are regarded as identical with the European species C. truncatus and D. Olrikii; the species C. americanus Cooper, and Bothrimonus intermedius Cooper are rejected. The triaenophorid common in the area is regarded as Triaenophorus tricuspidatus (Bloch), and two morphae are recognized, microdentatus and megadentatus, the latter equivalent to T. robustus (Olsson). Bothriocephalus cuspidatus Cooper is regarded as comprising three sub-species, cuspidatus, hiodontos and luciopercae. The eubothriid cestode in Lota lota maculosa is regarded as identical with the European E. rugosum, but comprising two morphae, conformatus and deformatus. Two new species of Proteocephalus are described, namely coregoni from Coregonus atikameg, and luciopercae from Lucioperca vitreum.

Stratigraphic Range

Galecyon is one of the first appearing hyaenodontid creodonts, as well as one of the most poorly known. New specimens greatly improve our understanding of the morphology of this early Eocene genus, thereby enhance knowledge of the earliest radiation of Hyaenodontidae, and include the first associated upper dental remains, as well as fragmentary cranial remains. The new records substantially expand the stratigraphic range of the genus and allow recognition of two new species. The first, Galecyon peregrinus n. sp., is a small, early species that includes the first records of Galecyon from the earliest Eocene Wa-0 interval. The second, Galecyon chronius n. sp., is a large, terminal species, represented by numerous specimens that extend the range of the genus into the late Wasatchian. The type species, G. mordax, is restricted to specimens that are intermediate in size and stratigraphic position. Phylogenetic analysis of early hyaenodontids confirms the monophyly of Galecyon and places it basal to Prolimnocyon, Prototomus, and Pyrocyon. Arfia is identified as the earliest diverging hyaenodontid sampled, contrasting with prior support for a more crownward position. Prototomus martis is more closely allied to Pyrocyon than to other species of Prototomus. The three North American species of Galecyon form a probable anagenetic lineage.

Abstract. Mennerotodus Zhelezko, 1994, is an extinct lamniform shark known to occur in Paleogene strata of the Tethyan region of Asia and Europe. Although only a single species has been named, multiple subspecies have been erected and used as biostratigraphic tools in Asia. The genus has not been reported with confidence outside of the Tethyan region, but we have identified two new species of Mennerotodus from Paleogene deposits of the southeastern United States. Mennerotodus mackayi sp. nov. is described by teeth occurring in the lower Paleocene (Danian Stage) Pine Barren Member of the Clayton Formation of southern Alabama. A middle Eocene (Bartonian) species, Mennerotodus parmleyi sp. nov., is based on material occurring in the Clinchfield Formation in central Georgia. The early Paleocene record could indicate a North American origin for Mennerotodus relatively soon after the K–Pg event, with subsequent radiation to other parts of the world. The genus is likely more widely distributed than is currently known, but teeth can easily be overlooked due to their similarity to other taxa.

Kribiodorum Kieffer, an otherwise North American and African genus of Chironomini (Diptera: Chironomidae), extends to the Oriental region through two new species. An adult male and female of Kribiodorum malicky sp. n. is newly described from Thailand, and from Brunei (Borneo) a pharate male and the pupa of Kribiodorum belalong sp. n. is described. Additionally, from Namibia (s.w. Africa) a 'manuscript' taxon is described formally with co-authorship of the late Arthur Harrison as Kribiodorum kunene sp. n. Males of the new species and the sole new pupa conform substantially to generic diagnoses based on the North American Kribiodorum perpulchrum (Mitchell). Examination of specimens of African Kribiodorum pulchrum Kieffer and N. American K. perpulchrum confirms their morphological similarity and reaffirms the junior synonymy of Stelechomyia Reiss designated for the North American species. Kribiodorum expands the number of genera of Chironomidae with African and Asian representatives, although unusual in its absence from Australia yet presence in the Nearctic.

Neopolystoma moleri n. sp. and Neopolystoma grossi n. sp. are described as new polystome species on the eyes of Apaloneferox and Pseudemys concinna floridana, respectively from Florida, USA. Eleven other polystome species are currently knownfrom chelonian hosts in the USA, but only Neopolystoma elizabethae and Neopolystoma fentoni were described from the eye.Ocular polystomes are characterized as having spindle-shaped eggs; an exceptionally firm grip on the host; as well as the abilityto stretch, which gives them the advantage of being stationary while extending to feed, reducing the risk of being dislodged.The two new species can be distinguished from known Neopolystoma species by a combination of characteristics including marginal hooklet morphology.

Two new species of the hexactinellid family Tretodictyidae, both collected by submersible, have been discovered off the coasts of North America. The Pacific species, Tretodictyum montereyensis n. sp., has an unusual skeleton with a fused cortex added over the usual tretodictyid system of ridges and grooves on the dermal surface. The Atlantic species, Hexactinella carolinensis n. sp., is unusual among its congeners in having swollen nodes on the dermal skeleton. Diagnoses of both genera have been modified to accommodate the new findings. The fine diactins of both species are found to have shallow brackets and short barbs, confirming their uncinate nature. Addition of these two species raises the number of known North American tretodictyids from one to three.
