A total of 17 species of cladid crinoids are documented from the late Kinderhookian Meadville Shale Member of the Cuyahoga Formation of northeastern Ohio, the most diverse assemblage of Kinderhookian-age cladids known in North America. One new genus, six new species, and seven new combinations are reported. New taxa include Cuyahogacrinus lodiensis new genus and species, and the new species Cyathocrinites simplex, Atelestocrinus meszarosi, Goniocrinus sceletus, Aphelecrinus gracilis, and Lebetocrinus ohioensis. New combinations include Logocrinus warreni (Laudon et al., 1952), Histocrinus aegina (Hall, 1863), Paracosmetocrinus richfieldensis (Worthen, 1882), P. corycia (Hall, 1863), Acylocrinus lyriope (Hall, 1863), Linocrinus merope (Hall, 1863), and L. paternus (Hall, 1863). Remaining taxa include Cyathocrinites lamellosus (White, 1863) and Ascetocrinus whitei (Hall, 1861), both of which also occur in the Osagean Burlington Limestone, and the endemic species Cosmetocrinus crineus (Hall, 1863) and Pachylocrinus subtortuosus (Hall, 1863).Collectively, the cosmopolitan genera and species of cladids show a greater overall affinity with Osagean cladid faunas than with other Kinderhookian cladid faunas. However, this is true for other Kinderhookian cladid faunas as well that individually have more taxa in common with Osagean faunas than other Kinderhookian faunas. This suggests a greater degree of endemism and local speciation during the Kinderhookian as a prelude to the rapid radiation of cladids, and other crinoids, during the Osagean.

New portunoid fossils from southern Argentina and from the west coast of North America permit the reevaluation of the generic and family relationships within the Portunoidea Rafinesque, 1815. It has previously been suggested that the Portunidae and the Geryonidae Colosi, 1923, are closely related families (Manning and Holthuis, 1989). The new fossils suggest that the Geryonidae may in fact be derived from a portunid progenitor,ProterocarcinusFeldmann, Casadío, Chirino-Gálvez, and Aguirre Urreta, 1995, through a process of peramorphosis in which juveniles of the geryonid speciesChaceon peruvianus(d'Orbigny, 1842) resemble adults ofProterocarcinus latus(Glaessner, 1933). Examination of several genera within the portunid subfamily Polybiinae Ortmann, 1893, includingImaizumilaKarasawa, 1993;Megokkosnew genus;MinohellenusKarasawa, 1990;PororariaGlaessner, 1980;PortunitesBell, 1858; andProterocarcinus,suggests that the subfamily had an amphitropical distribution early in its history. New taxa reported here includeMegokkosnew genus andPortunites nodosusnew species. New combinations includeChaceon peruvianus(d'Orbigny, 1842),Imaizumila araucana(Philippi, 1887),Megokkos alaskensis(Rathbun, 1926),Megokkos hexagonalis(Nagao, 1932),Megokkos macrospinus(Schweitzer, Feldmann, Tucker, and Berglund, 2000),Minohellenus triangulum(Rathbun, 1926), andProterocarcinus latus(Glaessner, 1933).

In preparation for upcoming studies, several new taxa of Australian Erotylinae (Coleoptera: Erotylidae) need to be described to make names available. New genera and species in Dacnini and Megalodacnini are described. Echinothallis banderbearella, new genus and species (Dacnini); Microdacne, new genus, with four new species (Dacnini), M. gloriousa, M. lamingtonia, M. nardia, M. styxia; and Episcaphula (Tropidoscaphula) megalodacnoides, new species (Megalodacnini). Variation of female terminalia and other characters in several genera are discussed regarding the monophyly and generic diversity of Dacnini.

The Detarieae, a small tribe of tropical arborescent Leguminosae, has been reported as host of two species of jumping plant-lice: the Neotropical Macrocorsa beeryi (Caldwell) on Hymenaea courbaril and the Afrotropical Retroacizzia mopanei (Pettey) on Colophospermum mopane. Here we add from Brazil 18 new species of Colophorina, Jataiba gen. nov. and Mitrapsylla from Copaifera, as well as nine species of Jataiba gen. nov. and Platycorypha from Hymenaea. In addition to Jataiba, a new genus which is created for five new species on Copaifera and one on Hymenaea, we erect the new genus Apsyllopsis for Psyllopsis mexicana, which is synonymised with Psyllia beeryi Caldwell. Two new combinations are proposed: Apsyllopsis mexicana (Crawford), comb. nov. from Psyllopsis, and Epiacizzia favis (Brown & Hodkinson), comb. nov. from Euphalerus. The new taxa are described and illustrated, and keys are provided for the identification of adults and immatures, as far as known. Immatures of Apsyllopsis and Colophorina induce galls on the leaves whereas those of the other taxa are free-living. Colophorina spp. seem to be monophagous whereas members of the other genera tend to be oligophagous. All host species are associated with two or more psyllid species. Copaifera langsdorffii, which hosts 11 species of three genera, constitutes a super-host.

The generic limits of Arrhenia Fries, Geotus Pil. & Svr., Leptoglossum Karsten, Leptotus Karst., Mniopetalum Donk & Singer, Phaeotellus Kühn. & Lam., Pleuromycenula Singer, and Rimbachia Patouillard are examined. Two genera, Arrhenia and Rimbachia, are recognized. Keys for the species in these genera are presented and reports of the various species are reevaluated based largely on a restudy of original materials. New combinations in Arrhenia are based on Agaricus fissus Leysser, Merulius lobatus Pers., Helvella retiruga Bull., Leptoglossum alnetorum Singer, and Cantharellus spathulatus Fr. New species combinations in Rimbachia are based on Cyphella arachnoidea Peck, Agaricus bryophilus Pers., Cyphella muscicola var. neckerae Fr., Cantharellus furfuraceus Petch, and Pleuromycenula ellipsoidea Singer. Rimbachia paludosa sp. nov. is described from Ontario, Canada. Leptoglossum muscigenum (Bull.:Fr.) Karst. is a synonym of A.spathulata (Fr.) Redhead, Mniopetalum globisporum Donk & Singer is a synonym of R.arachnoidea (Peck) Redhead, Mniopetalum distinctum Horak is a synonym of R.furfuracea (Petch) Redhead, Leptoglossum candidum Reid is a synonym of R.neckerae (Fr.) Redhead, and Geotus glaucus sensu Pilát & Svrček 1954 is actually A.fissa (Leyss.) Redhead. Mniopetalum bisporum Singer is reduced to a subspecies of R. arachnoidea and Mniopetalum megalosporum Singer to a subspecies of R. neckerae (Fr.) Redhead. In North America, Arrhenia auriscalpium is an arctic–alpine species, A. lobata is an arctic–boreal–alpine species, and A. acerosa and A. retiruga are boreal species. Rimbachia arachnoidea and R. bryophila are boreal species. Arrhenia spathulata and A. fissa are known only from Europe. All Arrhenia and Rimbachia species are bryophiles. Cantharellus polycephalus Bres. is transferred to Pterygellus Corner and Leptoglossum bambusicola Corner is transferred to Marasmiellus Murrill. Pseudocraterellus leptoglossoides Corner is a basidiolichen and the type of a new genus, Semiomphalina Redhead. Pleuromycenula circularis Singer is transferred to Helotium Tode, and P. flava Singer is the type of a new genus, Flabellimycena Redhead. Campanella inquilina Romagnesi, based on Leptoglossum conchatum sensu Romagnesi non Velenovský, is described as new. Cantharellus prescotii Weinm., the correct name for Cantharellus albidus auct. non Fries, is transferred to Gerronema.

We describe the Cephalozygoptera, a new, extinct suborder of Odonata, composed of the families Dysagrionidae and Sieblosiidae, previously assigned to the Zygoptera, and possibly the Whetwhetaksidae n. fam. The Cephalozygoptera is close to the Zygoptera, but differs most notably by distinctive head morphology. It includes 59 to 64 species in at least 19 genera and one genus-level parataxon. One species is known from the Early Cretaceous (Congqingia rhora Zhang), possibly three from the Paleocene, and the rest from the early Eocene through late Miocene. We describe new taxa from the Ypresian Okanagan Highlands of British Columbia, Canada and Washington, United States of America: 16 new species of Dysagrionidae of the existing genus Dysagrion (D. pruettae); the new genera Okanagrion (O. threadgillae, O. hobani, O. beardi, O. lochmum, O. angustum, O. dorrellae, O. liquetoalatum, O. worleyae, all new species); Okanopteryx (O. jeppesenorum, O. fraseri, O. macabeensis, all new species); Stenodiafanus (S. westersidei, new species); the new genus-level parataxon Dysagrionites (D. delinei new species, D. sp. A, D. sp. B, both new); and one new genus and species of the new family Whetwhetaksidae (Whetwhetaksa millerae).

New taxa of the family Ropalomeridae from Costa Rica are described, and additional records of ropalomerid flies fromMexico and Central America are provided. The new genus and species Acrocephalomyia zumbadoi can be easily distin-guished from all other ropalomerid genera by the following combination of characters: angular forward projection of head,absence of ocelli, flat face, bare arista, long scutum, and scutellum triangular-shaped and dorsally flattened with only onepair of apical bristles with bases approximated. The new species Ropalomera aterrima can be recognized from congenersby remarkable differences of the head, the shape of the scutellum, the absence of scutal vittae, fumose wings, and by theblack coloration of the body, ocellar bristles large, one postpronotal bristle, scutum without pollinose vittae and flat scutellum. Lenkokroeberia chryserea Prado and Kroeberia fuliginosa Lindner are newly confirmed for Costa Rica.
