Article Reference Introduced or established? Convergent evidence indicates imported pine wood nematode vectors occupy gaps in native distribution
Monitoring regulated quarantine plant pathogens and, when relevant, their vectors is compulsory in the European Union. Local Monochamus species (Coleoptera, Cerambycidae) vector the pine wood nematode, Bursaphelenchus xylophilus, a non-native pest already established in most of Portugal. Only 29 M. galloprovincialis individuals were trapped in Belgium in ten years (2013–2022), despite a dense coverage of pheromone-baited traps, suggesting absence or a very rare local occurrence in the country. In the northern neighbouring countries, only one single established population is known in The Netherlands and one in Denmark. A species distribution model based on pheromone-trap catches (negative and positive) of M. galloprovincialis from 4,914 traps in 29 European countries between 2008 and 2019 was developed, using the overall climate conditions and the distribution of seven pine tree species as explanatory variables. The effect of spatial scale was tested with a multi-scale approach. With a 225*225 km spatial grain, the major explanatory variables were the mean diurnal temperature range and, to a lesser extent, the presence of Pinus spp. The model predicted a low probability of presence in Belgium, the Netherlands, Great Britain and north-western Germany compared to southern Europe. Genotyping allowed to conclude that at least some of the beetles caught in Belgium originated from foreign locations. All catches were located close to entry points, suggesting introduction with imported material. The small size of most of the Belgian pine stands may also explain the absence or apparently transient status, or rareness of Monochamus spp. This study thus suggests that surveys in Belgium should privilege entry points rather than local forest stands.

Article Reference A three-species problem: a further example of homeomorphy in freshwater Ostracoda (Crustacea), with the description of a new genus and new species from a Brazilian river
Homeomorphy is common in the valves and carapaces of Ostracoda. One of the best-known examples in non-marine ostracods is the morphological similarity in the extreme armature of anterior and posterior spines on the left valve in both Strandesia bicornuta Hartmann, 1964 from India and in Rudjakoviella prolongata (Triebel, 1962) Malz, 1973 from Margarita Island (West Indies). Here, we describe a third representative with such armature, Pseudocypricercus bonito gen. nov. spec. nov. from Brazil. These new taxa belong to the Cypricercinae McKenzie, 1971, which is characterized by the presence of the Triebel's loop in the middle of the attachment of the caudal ramus. The main characteristics of Pseudocypricercus gen. nov. are the shape and length of the β seta on the mandibular palp, which is slender and elongated, compared to other genera of this subfamily; the absence of seta d on the first thoracopod, and the absence of seta d2 on the second thoracopod, amongst other features. Pseudocypricercus bonito gen. nov. spec. nov. also has large anterior and posterior spines on the left valve as well as a posterior spine and the anterior blunt protrusion on the right valve. In addition, both the mandibular coxa and the third endite of the maxillula have remarkable large fist-like setae, while the male right prehensive palp has a perpendicularly positioned second segment. The similar armature on left valve and right valve in this taxon makes the homeomorphy known from R. prolongata and S. bicornuta into a “three-species problem”.

Four species are recorded for the first time from Ngounié Province, one from Estuaire Province, two from Moyen-Ogooué Province, one from Arboretum Raponda-Walker, and five for Crystal Mounts National Park. We report several new records of foraging heights in trees.
