  A new Cataleptoneta species (Araneae, Leptonetidae) from sulfidic caves in Greece and Albania Abstract A new species of the genus Cataleptoneta Denis, 1955, Cataleptoneta sulfur sp. nov ., is described from caves in the Vromoner Canyon (Sarandaporo River Valley), on the Greek–Albanian border (northwestern Greece and southern Albania), on the basis of both sexes. Drawings, scanning electron micrographs, and digital images of diagnostic features are presented. Analysis of COI mitochondrial barcode sequences confirmed the species distinction from all the other sequences. Within the species two separate lineages, unique to each cave were found. The genus Cataleptoneta is not monophyletic as now circumscribed and confirmed also by the phylogenetic analysis of the sequences.

Ramp traps versus pitfall traps for collecting epigeal arthropods: a case study in a coniferous forest in Southwest Finland


ABSTRACT

Pitfall traps are commonly used to sample epigeal arthropods, but they are not ideal in areas where soil disturbance is restricted or not possible. Ramp traps are a less well known alternative that does not require excavation. To compare the performance of the two trap types in capturing epigeal arthropods, both ramp (n = 12) and pitfall traps (n = 12) were set up in four paired transects in Korkiakallio forest (Turku, Finland), in summer 2022. The project team identified adult spiders to the species level, and other arthropods to the family level. Ramp traps captured significantly more individuals of ants (Hymenoptera: Formicidae), beetles (Coleoptera), true bugs (Hemiptera), and spiders of the species Minyriolus pusillus (Wider, 1834) (Araneae: Linyphiidae), while pitfall traps captured more myriapods (Myriapoda). Our findings provide additional evidence that ramp traps are not only a viable alternative to pitfall traps in challenging environments, but also complement (and should ideally be used alongside) pitfall traps.
