Species of Russula (Russulaceae), a large, cosmopolitan, ectomycorrhizal fungal genus are notoriously difficult to identify. To delimit species and to evaluate their morphology, we sequenced the similar to 400 bp ITS2 ribosomal DNA region from 713 Pacific Northwest Russula specimens from Benjamin Woo's exceptional collection. As a topological constraint for analysis of the ITS2, we sequenced and inferred a phylogeny from the ITS, LSU, RPB2 and EF1-alpha regions from 50 European and North American specimens of major clades in Russula. We delimited 72 candidate species from Woo's collection's ITS2 sequences using ABGD, GMYC, PTP, and mothur software. To guide application of names, we sequenced a similar to 200 bp portion of the ITS from 18 American type specimens. Of the 72 delimited species, 28 matched a type or a currently barcoded European species. Among the remaining 44 are poorly known or undescribed species. We tested the congruence of morphology with delimitations for 23 species represented by 10 or more specimens each. No morphological character alone was consistently diagnostic across all specimens of any of the 23 candidate species. Ordination of combined field characters followed by pairwise multivariate analysis of variance showed that centroids were significantly different in 221 of 253 species pair comparisons. Ordination also showed that specimens from the same species were widely dispersed, overlapping with specimens from other species. This explains why only 48.5% of specimens were correctly assigned to their species in a canonical variates analysis of combined field and spore characters. Based on sequence comparisons, we contribute to correcting the broad and confusing misapplications of European names that have long obscured patterns of Russula's geographical distribution and diversification. Our evidence suggests that morphology in Russula diverges slowly, and that phenotypic plasticity, convergence, or retention of ancestral polymorphisms blur the distinctions among recently derived species.

An important compendium of fossil fungi is now publicly available through a searchable online database. The original compendium was the work of Kalgutkar and Jansonius, who combed through 238 references and collated and annotated published descriptions for 1783 taxa of fungal fossils. By translating these data to a FileMaker Pro database and to the Web, we increase options for searching, sorting, annotating and updating this information. Database search results provide lists of names, ages and thumbnail images of palynomorphs. An individual record from the results list can be expanded in a new browser window to show a complete description for a taxon. The database is timely because developments in molecular systematics are helping to place spore characters in a phylogenetic framework. Some of the previously ambiguous fossil fungi can now be placed into phylogenetic lineages. We anticipate that the Web version of the data will serve as a convenient entry point into the fungal fossil record, leading to integration of more information from fossils into fungal phylogenies.

Taeniogonalos sauteri Bischoff: Fukui Prefecture Category: Prefectural endangered species, Class II
●Characteristics of the species
A beautiful species with a body length of 8-11mm and a yellow-reddish brown mottled pattern on its body.
Although much about its life cycle is unknown, eggs are laid on the leaves of willows and alder trees, and these eggs enter the bodies of lepidopteran larvae that feed on the leaves, and the lepidopteran larvae become food for hornets. It is a parasitic wasp with a complex life cycle in which the larvae of the hornet's hornet larvae grow inside the larvae of the hornet.
●Habitat
Distributed in Honshu, Shikoku, Kyushu, the Ryukyu Islands, and Taiwan.
In the prefecture, it has been collected from Izumi Village, Ono City, and Miyama Town from mid-September to mid-October.
It flies to the leaves of walnut and pear trees covered with aphids in search of honeydew, but the exact location of its habitat is unknown.
Factors threatening survival
The depopulation of rural areas has led to a decrease in the number of wooden houses, reducing the number of nesting sites for the hornets, which are their hosts, and the aerial spraying of herbicides and pesticides are threatening their survival.

Molecular phylogenies for the fungi in the Ascomycota rely heavily on 18S rRNA gene sequences but this gene alone does not answer all questions about relationships. Particularly problematical are the relationships among the first ascomycetes to diverge, the Archiascomycetes, and the branching order among the basal filamentous ascomycetes, the Euascomycetes. Would more data resolve branching order? We used the jackknife and bootstrapping resampling approach that constitutes the “pattern of resolved nodes” method to address the relationship between number of variable sites in a DNA sequence alignment and support for taxonomic clusters. We graphed the effect of increasing sizes of subsamples of the 18S rRNA gene sequences on bootstrap support for nodes in the Ascomycota tree. Nodes responded differently to increasing data. Some nodes, those uniting the filamentous ascomycetes for example, would still have been well supported with only two thirds of the 18S rRNA gene. Other nodes, like the one uniting the Archiascomycetes as a monophyletic group, would require about double the number of variable sites available in the 18S gene for 95% neighbor-joining bootstrap support. Of the several groups emerging at the base of the filamentous ascomycetes, the Pezizales receive the most support as the first to diverge. Our analysis suggests that we would also need almost three times as much sequence data as that provided by the 18S gene to confirm the basal position for the Pezizales and more than seven times as much data to resolve the next group to diverge. If more data from other genes show the same pattern, the lack of resolution for the filamentous ascomycetes may indicate rapid radiation within this clade. DOI 13. Carmean D, Kimsey L.

SYSTEMATIC Trigonalidae
A phylogenetic analysis of generic relationships and revised generic concepts for the Trigonalidae is presented. The Trigonalidae is divided into two subfamilies, the Orthogonalinae and the Trigonalinae. Orthogonalinae consists of a single primitive genus, Orthogonalys, sharing many generalized apocritan characters, but lacking advanced trigonalid characters including antennal tyloids and female metasomal armature. No synapomorphies have been detected for the Orthogonalinae. Trigonalinae are characterized by the presence of tyloids. The Trigonalinae were originally defined by the absence of female armature, and were therefore polyphyletic because armature has been lost several times. Within the revised concept of Trigonalinae, the tribe Trigonalini is characterized by the presence of elongate parameres and an intertorulus distance subequal to the distance between the torulus and the eye. A second tribe, Nomadinini, is based on the secondary loss of tyloids, and comprises the previous subfamilies Seminotinae, Nomadininae, Bareogonalinae and Lycogastrinae. The two tribes Trigonalini and Nomadinini share the presence of female armature, although in some Trigonalini it has been secondarily lost. The genera Labidogonalos Schulz, Lycogastroides Strand, Lycogonalos Bischoff, Nanogonalos Schulz, Poecilogonalos Schulz and Taiwanogonalos Tsuneki are synonymised under Taeniogonalos Schulz. The species Lycogaster zimmeri Bischoff, Tapinogonalos maschuna Schulz, and Trigonalys pictifrons Smith (placed in Lycogaster by Schulz, 1906a) are transferred to Taeniogonalos. The genera Discenea Enderlein and Stygnogonalos Schulz are synonymised under Trigonalys Westwood. The species Labidogonalos flavescens Bischoff, L. sanctaecatharinae Schulz, Trigonalys lachrymosa Westwood (placed in Lycogaster by Bischoff, 1938), T. maculifrons Cameron (placed in Labidogonalos by Bischoff, 1938) and T. rufiventris Magretti (placed in Lycogaster by Schulz, 1907a) are transferred to Trigonalys.Trigonalys costalis Cresson is synonymised with Taeniogonalos gundlachii (Cresson). Xanthogonalos fasciatus Bertoni and X.severini Schulz are synonymised with Trigonalys sanctaecatharinae (Schulz). Mimelogonalos partiglabra Riek and M. punctulata Riek are synonymised with M. bouvieri Schulz. Lectotypes are designated for Trigonalys melanoleuca Westwood and Taeniogonalos fasciatipennis (Cameron). The author of Trigonalys maculifrons is Sharp (1895), not Cameron (1897), and the author of Taeniogonalos enderleini is De Santis (1980), not Schulz 1906. Viereck (1914) designated Trigonalys pulchella Cresson as type of the genus Tapinogonalos Schulz, preceding Bischoff's (1938) designation, making Tapinogonalos a synonym of Orthogonalys. A new genus, Afrigonalys, is proposed for the three species that were described in ‘Tapinogonalos’sensu Bischoff, nec Viereck. Link DOI 12. Crespi, BJ; Carmean, DA; Mound, LA; Worobey, M; Morris, D.

Molecular Phylogenetics and Evolution 9: 163-180 Phylogenetics of social behavior in Australian gall-forming thrips: Evidence from mitochondrial DNA sequence, adult morphology and behavior, and gall morphology
Six species of Australian gall-forming thrips (Insecta: Thysanoptera) on Acacia exhibit soldier castes, individuals with reduced wings and enlarged forelegs that defend their gall against interspecific invaders. We used data from two mitochondrial genes (cytochrome oxidase I and 16S rDNA), adult morphology and behavior, and gall morphology to infer a phylogeny for Acacia gall-forming thrips with and without soldiers, and we used this phylogeny to evaluate hypotheses concerning soldier evolution. Phylogenies inferred from each data set analyzed separately yielded large numbers of most-parsimonious trees and weak support for most nodes. However, when analyzed together the data sets complemented and reinforced one another in such a way as to yield a well-resolved phylogeny. Our phylogeny implies that soldiers originated once or twice early in the history of this clade, that soldiers were lost once or twice, and that soldiers evolved from winged dispersers rather than from non-soldier within-gall reproductive offspring of foundresses. The phylogeny also provides evidence for long-term morphological stasis, an ancient split between eastern and western gall thrips species, and a high degree of conservatism in host-plant affiliations.

parthenogenesis; speciation; walking-sticks
We inferred a phylogeny for the walking-stick genus Timema (Insecta: Phasmatoptera) using mitochondrial DNA sequence, and we used the phylogeny to infer temporal patterns of speciation and the evolutionary history of parthenogenesis. Maximum parsimony, neighbour-joining and maximum-likelihood analyses of 660 base pairs (bp) of cytochrome oxidase I (COT) yielded phylogenies that were well resolved and topologically identical or very similar. Application of an insect molecular clock for COI suggests that the genus originated in southern California, northern Mexico or Arizona about 20 million years ago and underwent a burst of speciation 1.5-3 million years ago during the uplifts of the Sierra Nevada, Coast, and Transverse Ranges. The phylogeny indicates that the three parthenogenetic lineages of Timema have arisen independently and are each closely related to morphologically indistinguishable or similar sexual species. Each of the three lineages exhibits an allopatric or parapatric, and more northerly, distribution with regard to their closest sexual relative. COI divergence levels between each of the three parthenogens and their closest sexual relative suggest ancient origins of parthenogenesis, 1.5-3 million years ago, that may coincide with the extensive glaciation that formed the North American ice sheets.

Annual Review of Entomology 42: 51-71 Ecology and evolution of galling thrips and their allies
galls; behavior; tritrophic interactions; sociality
About 300 species of thrips belonging to 57 genera are known to form galls. Galls are caused by feeding, usually by one or more adults, on actively growing plant tissue. Most thrips genera with galling capabilities exploit multiple plant families, but there are several possible cases of thrips tracking the speciations of their host-plants. Gall morphology in thrips reflects insect phylogenetic relationships rather than those of plants. Galling species and their nongalling allies on Acacia in Australia exhibit a range of complex social behavior, including soldier castes, pleometrosis (i.e. joint colony founding), group foraging, and group defense, that is directly related to the nature of their domiciles. Galling thrips, by virtue of their haplodiploid genetic system and their ecological relationships with plants and natural enemies, are useful for analyzing a wide range of ecological, evolutionary, and behavioral questions.9. Crespi, B; Carmean, D; Vawter, L; VonDohlen, C. (1996) Molecular phylogenetics of Thysanoptera. Systematic Entomology 21: 79-87 Molecular phylogenetics of Thysanoptera
Analyses of morphological data on the higher-level phylogenetics of Thysanoptera have suggested two alternative hypotheses: (1) sister-taxon status of the monophyletic suborders Terebrantia and Tubulifera, and (2) paraphyly of Terebrantia with respect to Tubulifera. Analyses of nucleotide sequence data from the mitochondrial gene cytochrome oxidase I and the nuclear gene 18S rDNA using maximum parsimony, neighbour joining, and maximum likelihood provide strong support for the hypothesis of a sister-taxon relationship between the Terebrantia and Tubulifera. These data resolve this long-standing controversy in thysanopteran phylogenetics and provide a framework for further studies of higher-level relationships in this order.7. Carmean, D; Crespi, BJ. (1995) Do long branches attract flies? Nature 373: 666 Do long branches attract flies?
Strepsiptera and Diptera group together in phylogenetic analysis as an artefact resulting from the high substitution rates in their 18S rDNA sequences. The grouping is an excellent example of long-branch attraction resulting from the violation of the molecular clock for this gene. Link DOI 6. Carmean, D. (1995) Trigonalidae.

The Holometabola (insects with complete metamorphosis: beetles, wasps, flies, fleas, butterflies, lacewings, and others) is a monophyletic group that includes the majority of the world's animal species. Holometabolous orders are well defined by morphological characters, but relationships among orders are unclear. In a search for a region of DNA that will clarify the interordinal relationships we sequenced approximately 1080 nucleotides of the 5? end of the 185 ribosomal RNA gene from representatives of 14 families of insects in the orders Hymenoptera (sawflies and wasps), Neuroptera (lacewing and antlion), Siphonaptera (flea), and Mecoptera (scorpionfly). We aligned the sequences with the published sequences of insects from the orders Coleoptera (beetle) and Diptera (mosquito and Drosophila), and the outgroups aphid, shrimp, and spider. Unlike the other insects examined in this study, the neuropterans have A-T rich insertions or expansion regions: one in the antlion was 260 by long. The dipteran 185 rDNA evolved rapidly, with over 3 times as many substitutions among the aligned sequences, and 2-3 times more unalignable nucleotides than other Holometabola, in violation of an insect-wide molecular clock. When we excluded the long-branched taxa (Diptera, shrimp, and spider) from the analysis, the most parsimonious (minimum-length) trees placed the beetle basal to other holometabolous orders, and supported a morphologically monophyletic clade including the fleas + scorpionflies (96% bootstrap support). However, most interordinal relationships were not significantly supported when tested by maximum likelihood or bootstrapping and were sensitive to the taxa included in the analysis. The most parsimonious and maximum-likelihood trees both separated the Coleoptera and Neuroptera, but this separation was not statistically significant. The position of the Hymenoptera relative to other orders was not clarified. Including the less derived members in the analysis made the Hymenoptera appear paraphyletic. The two representatives of Neuroptera grouped together as did the two Diptera, both pairs with very significant bootstrap support. DOI 4. Carmean, D.

The biology of the Trigonalyidae (Hymenoptera) is reviewed, with emphasis on adult behaviour. New observations on the vespine parasitoid Bareogonalos canadensis (Harrington) are presented, including oviposition behaviour in Douglas-fir foliage and overwintering in the egg stage. Potential use of Bareogonalos spp. in biological control of vespines is discussed. DOI 3. Carmean, D.

Trigonalidae
Prior to 1900 the yellowjacket parasitoid Bareogonalos canadensis (Harrington) was known only from the holotype collected in 1893 at Victoria, British Columbia (Harrington. 1896. Canad. Entomol. 28: 108). and 27 specimens collected on Gabriola Island in 1897 by Taylor (1898. Canad. Entomol. 30: 14-15). The present deposition of 19 of these 28 specimens is known (Table 1). The holotype was reported lost by Townes (1956. Proc. U.S. Nat. Mus. 106: 295-304) but Sarazin (1986. Canad. Entomol. 118: 957-989) claimed that the holotype is in the Canadian National Collection (CNC). From a study of the pre1900 material, I conclude that the true holotype is in the Zoologisches Museum der Humboldt-Universitaet (Berlin).
Harrington (1896) described the holotype as a male. Taylor (1898) reversed the sexes of his series and Harrington accepted this mistake. Harrington erroneously stated that the holotype was a female, and described the "male" sex using three females (autotypes) (Harrington 1898. Canad. Entomol. 30: 15-16). Harrington's error, though noted by Schulz (1907a.; Wytsman, Genera Insectorum 61: 24 pp.)... Link 2. Carmean, D., J. C. Miller, and B. Scaccia.
