“…Platycerus caraboides larvae were directly collected from deadwood of deciduous trees in the Vicenza province of Italy (Scaccini, 2016;Scaccini, 2022). A Dorcus parallelipipedus adult and M. melolontha larva (third instar) were collected in Colchester, UK, with the D. parallelipipedus being from a population we have previously studied (Scaccini et al, 2023). The M. melolontha adult was collected from Shottisham, Suffolk, UK.…”

Rectal or cryptonephridial complexes have evolved repeatedly in arthropods, including in beetles where they occur in ~190,000 species of Cucujiformia and Bostrichoidea, and Lepidoptera where they occur in ~160,000 species. Sections of the Malpighian/renal tubules coat the outer surface of the rectum, acting as powerful recycling systems of the gut contents, recovering water and specific solutes. There are hints that a rectal complex evolved independently within another beetle group, Scarabaeoidea. Here we report our observations of rectal complexes in Scarabaeoidea, which support this view. We did not find a rectal complex in the related group, Staphylinoidea, or in Lucanidae, a basal group of Scarabaeoidea. We did observe rectal complexes inMelolontha melolontha(Melolonthini),Pachnoda marginataandCetonia aurata(Cetoniinae), consistent with previous reports from these groups. Intriguingly we found that rectal complexes occur in adult, but notM. melolonthalarvae, and larvae but not adults within Cetoniinae, indicating dramatic pupal remodelling of these organ systems. Insights into the structure of the rectal complexes of Scarabaeoidea are compared with the well-studied rectal complexes of Cucujiformia. Finally we discuss possible functions of the rectal complexes of beetles within Scarabaeoidea, and future approaches to address this question.

Stag beetles are saproxylic species that are associated with deadwood in the larval stage and play an important role in forest ecosystem dynamics. In Italy, Platycerus caprea and Platycerus caraboides are two small, elusive stag beetle species, whose known distribution is often limited or referring to old records. The present contribution increases the knowledge on the Italian distribution of P. caprea and P. caraboides, adding 70% more sites when compared to previously published records. Ecological traits, especially related to the altitude-elevation distribution in Italy, are also described for these saproxylic beetles.
