Taxonomic and nomenclatural issues in the butterfly family Hesperiidae are reviewed with reference to ICZN rules, historical treatments, recent phylogenetic studies, and prevailing usage. Particular attention is given to subfamily and tribal classifications, where older names and synonymies have at times conflicted with prevailing usage, requiring careful evaluation under the Code. At the genus level, long-debated cases such as the priority of Muschampia versus Sloperia are reviewed, while at the species level, complex situations such as the Pyrgus alveus species group and thestatus of names like bellieri and foulquieri are considered in detail. For the subfamily Heteropterinae, the relationship between the older name Cyclopidinae and the later but widely used Heteropterinae illustrates the importance of balancing historical accuracy with nomenclatural stability. The review emphasizes the need for consistent application of ICZN provisions in order to promote stability and comparability across regional checklists. Nonetheless, several issues remain unresolved,and further progress will depend on broad genomic research, preferably based on whole genomes, together with extensive morphological studies that consider the full variability of traits acrosspopulations.

A systematic and synonymic list of the Papilionidae of Western Palearctic butterflies hyperlinked to the original descriptions (Lepidoptera, Papilionoidea)

A systematic and synonymic list of the Papilionidae butterflies of the Western Palearctic is presented, with all names hyperlinked to their original descriptions. The work covers taxonomic hierarchy from family to species level, incorporating historical synonyms, typification details, and bibliographic references, providing a comprehensive and navigable tool for lepidopterists and taxonomists.

First Records of Neptis sappho (Pallas, 1771) in Albania.

Neptis sappho (Pallas, 1771), has a wide but fragmented range from Japan to Eastern Europe. Although previously undocumented in the literature, N. sappho was recently confirmed in Albania, occurring in habitats dominated by the invasive Robinia pseudoacacia. These records lie at the southern edge of its European range. Suitable habitats extend beyond the recorded sites, suggesting that N. sappho is likely more widespread in Albania than currently documented.

Lepidium didymum L., a new host plant for Pieris mannii (Mayer, 1851). Is this new host plant facilitating the species' rapid northwestern expansion?

The first confirmed use of Lepidium didymum (Brassicaceae) as a larval host plant of Pieris mannii (Mayer, 1851) is documented, based on oviposition and successful rearing in Belgium. The discovery of this new hostplant highlights the species’ ecological plasticity and may be a contributing factor regarding the ongoing expansion of the species across urbanised areas of north-western Europe. The widespread presence of L. didymum in disturbed habitats may help sustain and extend future populations.
