Article Reference Results of ant collections on Santa Cruz Island within the framework of the 2012 Global Taxonomy Initiative Ant Course at Galápagos (Hymenoptera: Formicidae)
During a ten-days ant course carried out in November 2012 within the framework of a Belgian Focal Point to the Global Taxonomy Initiative GTI type 2 grant, eight students and four instructors collected 22 ant species at ten sites distributed along an altitudinal gradient on Santa Cruz Island in the Galápagos Archipelago (Ecuador). Disturbed and urbanized zones as well as natural areas were visited. We discuss the results and link the collected species to altitude and vegetation types occurring on Santa Cruz Island.

Article Reference Survey on the distribution of the Sweet potato weevil, Cylas species-complex in Ghana (Coleoptera: Brentidae)
The Sweet potato weevils of the genus Cylas are the most destructive pests of sweet potato and are widely distributed in Africa. The aim of this study was to identify and document the species of Cylas occurring in sweet potato production zones in Ghana. A survey was conducted in 23 localities in 2015 from July to December in seven regions in Ghana in order to determine the identity of the pest. We collected nine thousand and two specimens from Central, Eastern, Greater-Accra, Northern, Volta, Upper-East, and the Upper-West regions. Two species were identified: Cylas brunneus Fabricius, 1797 and Cylas puncticollis Boheman, 1833. Cylas puncticollis occurred in all regions and represented 6,107 specimens (68%), while 2,895 of the specimens (32%) could be assigned to C. brunneus. The latter is restricted to the southern sector including Volta, Central, Eastern and Greater Accra Regions. When considering both species in the southern sector, the Volta Region accounted for 3,117 specimens (48%) followed by 1,447 (22%), 987 (15%), and 980 (15%), from the Central, Eastern, and Greater-Accra Regions, respectively. The dominant species in southern and northern sector was C. puncticollis.

Article Reference Camponotus fallax (Nylander, 1856), an expected species finally discovered in Belgium (Hymenoptera: Formicidae)
In this paper we announce the first observation of the ant Camponotus fallax (Nylander, 1856) in Belgium and add it to the Belgian checklist. Specimens were collected in Sint-Martens-Voeren with an eclector trap mounted on a dead fruit tree.

Article Reference Is Lasius bicornis (Förster, 1850) a very rare ant species? (Hymenoptera: Formicidae)
Since its description based on a single alate gyne by the German entomologist Arnold Förster, Lasius bicornis (Förster, 1850), previously known as Formicina bicornis, has been sporadically observed in the Eurasian region and consequently been characterized as very rare. Here, we present the Belgian situation and we consider some explanations for the status of this species.

Article Reference Silpha tyrolensis Laicharting, 1781 (Coleoptera: Silphidae), an unexpected addition to the Belgian fauna
In the course of the Belgian Silphidae Project, four specimens of Silpha tyrolensis Laicharting, 1781 were encountered when studying the unidentified Silphidae in the entomological collection of the Haute École Provinciale de Hainaut-Condorcet in Ath. These are the first records of this species for Belgium and are from the period 1990–2010. Subsequent recent trapping in the region where the specimens were found revealed no additional specimens. In this paper the records are presented and the distribution of the species in Belgium and Europe is mapped and discussed.

Article Reference First observations in Belgium of the introduced ‘minute hooded beetle’ Arthrolips fasciata (Erichson, 1842) (Coleoptera: Corylophidae)
In September 2020 a specimen of the Corylophidae Arthrolips fasciata (Erichson, 1842) was discovered in mushrooms on decaying beech in a garden in Sint-Denijs-Westrem. In October 2020 a second specimen of this species was discovered in Beisbroek Sint-Andries Bruges also on decaying beech. These are the first records of the species in Belgium. Hence, we expect more Belgian records of this species in the near future. A species list of the Corylophidae known to occur in Belgium is given.

Article Reference Note on Asilidae (Diptera) collected near Mount Kilimanjaro, Tanzania
We present a list of five species of Asilidae collected in February-March 2018 near Mount Kilimanjaro, Tanzania. Three species are new for science and are described here: Pegesimallus uhuruensis sp. nov., Ommatius uhuruensis sp. nov. and Oligopogon kilimanjaroensis sp. nov. Moreover, the species Machimus ugandiensis Ricardo, 1919 was recorded for the first time in Tanzania.

Article Reference 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.

Article Reference Confirmation of Nicrophorus sepultor Charpentier, 1825 as a Belgian species (Coleoptera: Staphylinidae: Silphinae)
In this note the status of the burying beetle Nicrophorus sepultor Charpentier, 1825 as a Belgian species is confirmed based on eight specimens found in the collections of the Royal Belgian Institute of Natural Sciences (RBINS). The records are presented, mapped and the diagnostic features of this species are given.

Article Reference Recent and old records of the rare myrmecophilous beetle Haeterius ferrugineus (Olivier 1789) in Belgium, Luxembourg and North-East of France
Haeterius ferrugineus (Olivier 1789) is a rarely observed histerid beetle which lives permanently in ant nests. We provide the first records of this species in Flanders, the northern part of Belgium, and give an overview of the scattered records for this species in Belgium, Grand-Duché of Luxembourg and the border region in the North of France gathered over the past 150 years.
