A new species of freshwater crab of the genus Hydrothelphusa A Milne-Edwards, 1872, is described based on specimens collected from a forested region of southeastern Madagascar. Hydrothelphusa vencesi n. sp. is clearly distinguished from its congeners by its distinctive first gonopod (G1) with a terminal article that is in the form of a long straight-sided cone, and by a dorsal membrane at the segment junction of G1 that is broad and diamond-shaped. A key is provided to separate the five species of Hydrothelphusa.

The established historical view of the Upper Guinea Coast is that this naturally forested region was at first peripheral to the Manding civilization of the savanna zone. The arrival of Europeans on the coast in the fifteenth century then engendered a southward shift in the centre of gravity of historical processes. The Atlantic trade, in which the savanna states were also deeply involved, gave coastal populations vastly expanded opportunities for wealth accumulation and social mobility. In spite of numerous attempts at political centralization, ‘frontier’ conditions persisted in the region up to – and perhaps after – the establishment of colonial states. These conditions have been held to account for the region-wide importance of cultural institutions which either facilitate social accommodation between heterogenous groups (e.g. Islam, Manding and European linguistic creoles, Manding clan names, and secret societies), or reflect such processes (e.g. bilateral kinship, patron–client relations, and pre-colonial urbanization).

Lepidopteran assemblages were studied at 16 sampling sites in the Hajdúság Region between 2013 and 2020. Although studies targeted development of synthetic phenylacetaldehyde-based and semi-synthetic isoamyl alcohol-based baits for pest monitoring, traps caught 179 species belonging to the Sphingidae, Thyatiridae, Geometridae, Erebidae and Noctuidae families. Most species were pests or widely distributed generalists, but there were also many rare habitat specialists, for example, silvicol species, whose appearance was unexpected in the recently less forested region. The specificity of the two bait types tested differed notably both on family and subfamily levels. Semi-synthetic baits performed better and attracted a wide range of noctuids belonging mainly to the Xyleninae and Noctuinae subfamilies, while synthetic phenylacetaldehyde-based lures showed specificity to Plusiinae subfamilies with lower number of sampled species. Our data fill a gap of knowledge since the fauna studied formerly was nearly unknown and brings attention to the alternative use of volatile traps of agricultural pests in faunistical studies.
