New hyaenodonta (Mammalia) from the middle Eocene of Myanmar
- The middle Eocene Pondaung Formation in Myanmar has yielded a rich mammalian faunaincluding several Primate taxa. Hyaenodonta are known by the genera Kyawdawia, Yarshea,Orienspterodon, and two other indeterminate taxa. We describe here new material of Kyaw-dawia, including some morphological details, a new species of the hypercarnivorous genusPropterodon and an indeterminate species, different from those described earlier in Myan-mar, and characterized by a reduction of m3 and would belong to a third lineage with thesame evolutionary trend as Galecyon and the Limnocyoninae. The hyainailourines (Orien-spterodon) and hyaenodontines (Propterodon) are recorded for the first time in SoutheastAsia and these subfamilies appeared in quasi the same time in Europe illustrating probablya profound change in the carnivorous fauna among Laurasia.

Belgium on the lookout for exotic mosquito species (Diptera: Culicidae).
- Based on the current spread of exotic mosquito species (EMS) in Europe, the number of interceptions in Belgium and suitability models developed for Aedes albopictus (Skuse) in Europe, EMS are likely to establish and spread in Belgium. A prerequisite for their control is their early detection. Therefore, the Belgian federal authorities and the federated entities funded a 3-year active monitoring project (MEMO) (July 2017–June 2020). The aims are early detection of EMS in Belgium, quantifying locally established EMS populations, evaluating the EMS import risk at possible points of entry (PoE), expand reference collections and make recommendations for a future, long-term, cost-effective EMS monitoring plan in Belgium. Monitoring activities are implemented at 23 PoE using adult trapping with CO2 and lure traps, egg sampling with oviposition traps and larval sampling with dipping nets. DNA barcoding is used to validate morphological identifications and to expand the DNA reference database. Specimens are also added to the morphological reference collection at Royal Belgian Institute of Natural Sciences. Since July 2017, four EMS were intercepted. The colonised area of Ae. koreicus (Edwards) in Belgium increased from 7 to 113 km2. Aedes japonicus (Theobald) was detected again in southern Belgium, from where it was thought to be eliminated. This species has now also been collected on the border with Germany. Anopheles pharoensis (Theobald) entered Belgium via cargo transport. Aedes albopictus was intercepted at four PoE. To conclude, EMS are effectively entering and spreading in Belgium and appropriate control management strategies on the national level are urgently required.

The state of the art of the exotic mosquito species in Belgium: new invasion pathways detected.
- In July 2017, a three year monitoring project (MEMO) aiming at detecting and evaluating the occurrence and invasion phase of exotic mosquitoes (EMS) in Belgium started. Adult traps and ovitraps were placed and larval sampling was conducted at 23 locations. These locations were selected based on their high potential of introducing EMS. DNA-based techniques are used to verify the morphological identification of 5% of the collected mosquito specimens. In 2017, 2622 adult mosquitoes, 2916 larvae and 650 eggs were collected. In total 15 species (or complexes) belonging to 5 genera (Aedes, Anopheles, Culex, Culiseta and Coquillettidia) were identified. Morphological and DNAbased identifications were in agreement. Furthermore, DNA sequence data confirmed that adults of the Anopheles maculipennis complex were Anopheles messeae and that both Culex pipiens biotype pipiens and biotype molestus were collected. Culiseta longiareolata was for the first time observed in Belgium. EMS made up 2% of all collected specimens. Three EMS, Aedes japonicus, Aedes koreicus and Anopheles pharoensis were intercepted in 2017. In the first six months of 2018, Aedes albopictus was intercepted at four locations. Previous monitoring projects indicated that Aedes mosquitoes entered Belgium via import of lucky bamboo plants and of tyres. New for Belgium is the interception of Aedes albopictus and Aedes japonicus along the border with France and Germany, respectively. And the interception of Anopheles pharoenis in a cargo airport. In the first case, a possible natural spread from these countries may have occurred. In this perspective, the understanding of the invasion process of the three exotic Aedes species, based on field observations and population genetics, will provide information on their invasion phase (introduction, establishment or spread) and seasonality which will be essential to guide surveillance and control.
