Abstract The genus Ceartocystiopsis includes ascomycetes fungi belonging to the Ophiostomatales that are not well recognized in the world. Described species so far have been found mainly in association with bark beetles in the Northern Hemisphere. The aims of this study were therefore to survey of distribution of species of Ceratocystiopsis associated with bark beetles infesting Picea abies and Pinus sylvestris in Norway. Adults for 22 different bark beetle species were collected from 13 stands in Norway. During this study, we recovered 126 isolates showing affinities to Ceratocystiopsis representing six species, including two described and four undescribed taxa. The four undescribed taxa collected during this work were characterised based on their morphological characteristics and multi-gene phylogenies. Herein, we describe these new species as Ceratocystiopsis chalcographii sp. nov., Ceratocystiopsis debeeria sp. nov., Ceratocystiopsis norroenii sp. nov. and Ceratocystiopsis troendelagii sp. nov. Ceratocystiopsis norroenii and C. rollhanseniana were the most frequently isolated species although the latter species had a much wider vector range. This study expands our knowledge about the taxonomy and species diversity of Ceratocystiopsis and beetle-fungus relationships.

Xestocephalus Van Duzee is among the most common and widespread genera of Cicadellidae in the temperate and tropical regions of the world. In the present study, 205 specimens of the genus Xestocephalus were collected in Thailand, whereas only a single species of the genus was recorded previously using Malaise trap field sampling, studied by comparative morphology. Seventeen species were recognized, including twelve new species: X. binarius sp. nov., X. chrysanthemum sp. nov., X. cowboyocreus sp. nov., X. densprint sp. nov., X. dimiprocessus sp. nov., X. exproiecturus sp. nov., X. gracilus sp. nov., X. limpidissimus sp. nov., X. malleus sp. nov., X. nonattribus sp. nov., X. recipinams sp. nov., and X. tenusis Liang sp. nov. Four species were recorded in Thailand for the first time: Xestocephalus abyssinicus Heller and Linnavuori, Xestocephalus asper Linnavuori, Xestocephalus ishidae Matsumura, and Xestocephalus toroensis Matsumura. Detailed morphological descriptions of all 17 species are given; photographs of external habitus and male genitalia of the species from Thailand are provided. A checklist of species of the genus is also given, and a key to all Thailand Xestocephalus species is also provided.

Taxonomic System

Agaricus is a species-rich genus with more than 500 species over the world. Recent studies on tropical Agaricus revealed new tropical clades and a revised taxonomic system was consequently developed. Agaricus subg. Minoriopsis, a sixth subgenus was recently added, comprising species exclusively from the Americas. The diversity of Agaricus is little studied in Mexico, despite this country has a long history in the consumption of wild edible fungi. In this paper, we introduce a new species A. guzmanii and a new record for A. globocystidiatus from Mexico based on morphological characteristics and molecular data. Phylogenetic analyses indicate that they belong to A. subg. Minoriopsis.

Previous studies and data presented here suggest that odors from healthy host Scotch pine (Pinus sylvestris) and nonhost Norway spruce (Picea abies), as well as major monoterpenes of these trees at natural release rates, significantly reduce the attraction of flying bark beetles,Pityogenes bidentatus, of both sexes to their aggregation pheromone components grandisol andcis-verbenol in the field, as tested by slow rotation of trap pairs. In contrast,P. bidentatusmales and females walking in an open-arena olfactometer in the laboratory did not avoid monoterpene vapors at release rates spanning several orders of magnitude in combination with aggregation pheromone. The bark beetle may avoid monoterpenes when flying as a mechanism for avoiding nonhost species, vigorous and thus unsuitable host trees, as well as harmful resinous areas of hosts. Inhibition of this flight avoidance response in beetles after landing would allow them to initiate, or to find and enter, gallery holes with high monoterpene vapor concentrations in order to feed and reproduce.

Great Knowledge

Although the world species diversity of Marilia Müller 1880 is not great, knowledge about this group may be underestimated, since several areas are poorly studied, especially in Northeast Region, Brazil. Two new species are described and illustrated here based on specimens collected in Maranhão State, from which the genus has not been reported previously. Despite the similarity of Marilia caramuru sp. nov. with M. elongata Martynov 1912, differences between them are observed especially in segment X and preanal appendages, in addition to details of wing venation. The unique set of spiniform projections on endotheca, and the wrinkled prominence on sternum VIII distinguish Marilia paraguassu sp. nov. from all other species in the genus. The material examined has been deposited in the Coleção Entomológica Professor José Alfredo Pinheiro Dutra, UFRJ, Rio de Janeiro, Brazil, and in the Coleção Zoológica do Maranhão, UEMA, Maranhão, Brazil.

A study aiming at the description of invertebrate fauna trapped in contemporary, coniferous resins was undertaken in a mixed forest of Central Europe (Southern Poland). Resins were collected predominately from spruce (Picea abies), but also from pine (Pinus sylvestris) and larch (Larix decidua), the cadavers were extracted from the ethanol solution of resin. As many as 394 specimens were extracted, consisting mainly of insects, but also arachnids, crustaceans and single mollusc were found. Among the collected specimens, some were identified to species, and a few mutual, ecological interrelationships could be traced. Although the amount of collected resins is far from being comparable with the amount of particular types of amber studied in the world so far, the Discussion focuses on similarities and differences in insect inclusions composition in resins and known amber collections.

A new Oodinychus Berlese, 1917 species, O. scolytana sp. nov., was discovered and described from the galleries of bark beetles Polygraphus proximus Blandford from two different parts of Asian Russia. New associations are given for the trematurid mites and bark beetle species. Three bark beetle associated species from the Trichouropoda ovalis-group are moved into the genus Oodinychus as O. hirsuta (Hirschmann, 1972) comb. nov., O. rafalski (Wiśniewski & Hirschmann, 1984) comb. nov. and O. wilkinsoni (Hirschmann &Wiśniewski, 1986) comb. nov. Also, Oodinychus egypticus Abo-Shnaf, El-Bishlawy & Allam, 2018 is transferred to the genus Nenteria Oudemans, 1915.

Three tiger beetle species, Therates differens Sawada & Wiesner, 1999, Calomera brevipilosa (W. Horn, 1908) and Cosmodela separata (Fleutiaux, 1893), are recorded from Vietnam for the first time. The known tiger beetle fauna of this country is thus raised to a total of 132 species (45, or 34% of which are endemic), what definitely ranges Vietnam among the countries of the world with the richest outstanding entomological biodiversity (km2/species ratio: 2.507).

A New Species

The genus Ephoron Williamson, 1802 is widely distributed around the world. In Thailand, only Ephoron indicus Pictet, 1843 was reported in 1961. In this study, a new Ephoron mayfly is described as Ephoron ookaewae sp. nov. In this new species description, the morphological characteristics of larvae and eggs in addition to adults are also shown in detail. Number of tubercles on mandibular tusks, and a median frontal process in larvae, distinguish Ephoron ookaewae sp. nov. from other Ephoron species. Their polar cap shape and a concave indentation in their eggs are also unusual. In addition, the mitochondrial DNA COI sequence data of the newly described Ephoron ookaewae sp. nov. is registered in GenBank. Registration of sequence data for the DNA barcode region of Ephoron mayflies inhabiting the Oriental region remains limited, however it will be useful for future research.

Dialium (Leguminosae, Dialiinae) is pantropical and comprises about 40 species. Presently, only one species occurs in the Neotropics, Dialium guianense, which is found from eastern Mexico to northeastern Minas Gerais, Brazil. The objective of this study was to carry out a thorough taxonomic revision of Dialium in the Neotropics, to determine if species diversity of the genus in this region is underestimated. The study analyzed 765 collections, from 18 herbaria throughout the world, which revealed three groups of specimens that clearly differ from each other and from D. guianense. Morphology and biogeography support their recognition as new species. Dialium hexaestaminatum occurs in northern Colombia and western Venezuela, and is characterized by generally having six stamens, while the other neotropical species have only two. Dialium congestum occurs in Ecuador and southern Colombia and is mainly characterized by the presence of congested inflorescences, unlike the lax inflorescences found in the other neotropical species.  Dialium rondoniense occurs in the state of Rondônia and the most southern part of the state of Amazonas, Brazil. It is characterized by the dense coverage of trichomes on the abaxial surface of the leaflets, as well as the petiolules, petioles, leaf rachis and branches, while the other neotropical species are generally glabrous or covered with sparse trichomes that are imperceptible to the bare eye. The results show that the diversity of Dialium in the Neotropics was underestimated and that the genus has four species in the region. An identification key, illustrations and descriptions of the species are provided.
