First record of three alien termite species in Belgium
-
Subterranean termites (Family Rhinotermitidae) and drywood termites (Family Kalotermitidae) can be pest species as they have the potential to inflict damage to wooden constructions and can therefore cause a significant economic impact. Some species of these families are highly destructive and are invasive in many parts of the world. New introductions and/or the spread of termites are often caused by import of infested wood, plants or soils. The present study reports the first records of three exotic termite species in Belgium, viz. Cryptotermes brevis and Reticulitermes banyulensis in Brussels (Brussels Capital Region), and Reticulitermes flavipes in Brugelette (Hainaut province; Walloon region). The morphological identification of the specimens (N = 8) was validated by DNA-barcoding. Cryptotermes brevis and Reticulitermes banyulensis infestations are probably of little concern as local climatological conditions make it unlikely for either species to survive in the temperate climate in Belgium. In contrast, it is likely that Reticulitermes flavipes may become established and will spread to other sites in Belgium.

First records for Belgium of the ant species Myrmica vandeli Bondroit, 1920 (Hymenoptera: Formicidae)
-
We report the first observations of Myrmica vandeli Bondroit, 1920 for Belgium. The species was found in an oligotrophic, undisturbed wet grassland in Richtenberg, Burg-Reuland in 2011 and 2021. This Myrmica species is rare in Europe and restricted to open wet meadows, swamps, fens and peatlands. Myrmica vandeli is added to the ant fauna of Belgium which now numbers 12 Myrmica species. It is possible that M. vandeli specimens were previously confused with specimens of its sister species Myrmica scabrinodis Nylander, 1846. Hence we suggest to revise all M. scabrinodis samples from the south-eastern part of Belgium (from Hautes Fagnes south to Luxembourg) as it is possible that M. vandeli was left unnoticed before and identified as M. scabrinodis.

First records of a supercolonial species of the Tapinoma nigerrimum complex in Belgium (Hymenoptera: Formicidae)
-
In the summer of 2014, a highly supercolonial Tapinoma was discovered in Ostend, Belgium. This was the first time a Tapinoma species with an invasive behaviour was discovered outdoors in Belgium. The ant belongs to the most widely distributed of four recognized species of the Tapinoma nigerrimum complex and is the only known species being invasive in areas north of the Mediterranean zone. In a first attempt to eliminate the species, a Demand 10CS insecticide solution treatment was initiated in 2015. First results illustrate that this treatment might be efficient, however a long-term monitoring of the site and its neighbourhood are suggested.

First report of the exotic blue planarian, Caenoplana coerulea (Platyhelminthes, Geoplanidae), on Menorca (Balearic Islands, Spain)
-
In April 2009 two specimens of a terrestrial flatworm were collected from under a rock in an orchard at Ciutadella de Menorca on the easternmost Balearic island of Menorca (Spain). Their external morphology suggested that both specimens belonged to the invasive blue planarian Caenoplana coerulea, a species which is native to eastern Australia. Sequence data of a fragment of the mitochondrial cytochrome c oxidase subunit I (COI) and of the entire 18S ribosomal RNA confirm its identification. This is one of the first records of the species in Europe where it has only been found in one locality in the United Kingdom, France and NE Spain.
