Article Reference Secrets of de Selys Longchamps archives: one watercolour and two records of nineteenth century observations of the grasshopper species Psophus stridulus (Linnaeus, 1758) and Locusta migratoria (Linnaeus, 1758) in Belgium (Orthoptera: Acrididae)
Next to voucher specimens in entomological collections, also historical archives and historical illustrations can contain valuable taxonomical as well as ecological and faunistic data. We report here faunistic data for two currently extinct Belgian grasshopper species from the year 1862, deduced from a letter accompanied by a watercolour. The letter and watercolour are stored in the archives of Edmond de Selys Longchamps at the Royal Belgian Institute for Natural Sciences (RBINS). Both the watercolour and the letter are discussed, focusing on the observations of Psophus stridulus (Linnaeus, 1758) and Locusta migratoria (Linnaeus, 1758) (Orthoptera) at Lanaken in 1862. Two voucher specimens of these observations and their original labels, that are stored in the RBINS collections, were studied. We can conclude that Egide Fologne was the first to observe P. stridulus in Belgium. He reported this in a letter to Edmond de Selys Longchamps and supplied the watercolour depicting the specimen he collected and donated to Selys for his collection.

Article Reference Integrative taxonomy of giant crested Eusirus in the Southern Ocean, including the description of a new species (Crustacea: Amphipoda: Eusiridae)
Among Antarctic amphipods of the genus Eusirus, a highly distinctive clade of giant species is characterized by a dorsal, blade-shaped tooth on pereionites 5–7 and pleonites 1–3. This lineage, herein named ‘crested Eusirus’, includes two potential species complexes, the Eusirus perdentatus and Eusirus giganteus complexes, in addition to the more distinctive Eusirus propeperdentatus. Molecular phylogenies and statistical parsimony networks (COI, CytB and ITS2)of crested Eusirus are herein reconstructed. This study aims to formally revise species diversity within crested Eusirus by applying several species delimitation methods (Bayesian implementation of the Poisson tree processes model, general mixed Yule coalescent, multi-rate Poisson tree processes and automatic barcode gap discovery) on the resulting phylogenies. In addition, results from the DNA-based methods are benchmarked against a detailed morphological analysis of all available specimens of the E. perdentatus complex. Our results indicate that species diversity of crested Eusirus is underestimated. Overall, DNA-based methods suggest that the E. perdentatus complex is composed of three putative species and that the E. giganteus complex includes four or five putative species. The morphological analysis of available specimens from the E. perdentatus complex corroborates molecular results by identifying two differentiable species, the genuine E. perdentatus and a new species, herein described as Eusirus pontomedon sp. nov. ADDITIONAL KEYWORDS: alpha taxonomy – cryptic species – genetics – molecular systematics – phylogenetic systematics.

Article Reference Newly discovered crocodile mummies of variable quality from an undisturbed tomb at Qubbat al-Hawā (Aswan, Egypt)
A description is provided of the crocodile remains that were found during an excavation carried out in 2019 at Qubbat al-Hawā (Aswan, Egypt). The material consists of five more or less complete bodies and five heads that were in varying states of preservation and completeness. The absence of resin, which was apparently not used during the preparation of the mummies, and the almost complete loss of linen bandages, due to insect damage, allowed a detailed morphological and osteometric description of the remains. Attention was focused on the general state of preservation of the crocodiles, the completeness of their skeletons and skulls, the presence of cut or other marks that could indicate the cause of death, and the processing of the carcasses. Moreover, the possible provenance of the crocodiles, the methods of capture and killing of the animals and their possible chronological attribution are discussed. It is concluded that the manner in which these specimens were prepared, as well as the variation observed in the type of ‘final product’, are unlike any other crocodile material described so far. The preparation method suggests a pre-Ptolemaic date for the deposit. The morphological and metrical features indicate that both Crocodylus niloticus and the recently resurrected species Crocodylus suchus are present among these individuals that range from 1.8 to 3.5 m in length.
