One of the major problems hindering the systematic study of tachinid flies is that genera are often poorly defined, making it difficult to unambiguously assign species among closely related genera. Within the tribe Winthemiini, an example of this problem is represented by the unstable classification of the Afrotropical species most recently classified as Smidtia capensis (Schiner). This species has been previously assigned to four different genera on the basis of limited examination and evidence. Here, we evaluate the identity and phylogenetic affinities of this species and other members of the tribe Winthemiini using morphological and molecular phylogenetic analysis. We demonstrate that S. capensis actually belongs to the genus Winthemia Robineau-Desvoidy. We also find that Winthemia is paraphyletic with respect to two monotypic genera, Crypsina (type species Crypsina prima Brauer & Bergenstamm) and Hemiwinthemia (type species Hemiwinthemia calva Villeneuve). On the basis of morphological and genetic evidence, we propose to extend the generic limits of Winthemia to include W. londti, sp. nov. (South Africa), W. capensis (Schiner), comb. nov. (South Africa), W. prima (Brauer & Bergenstamm), comb. nov. (China, Japan, Australia) and W. calva (Villeneuve), comb. nov. (D.R. Congo), thus synonymising with Winthemia the generic names Crypsina, syn. nov. and Hemiwinthemia, syn. nov.

Half a century of research on bystander behavior concludes that individuals are less likely to intervene during an emergency when in the presence of others than when alone. By contrast, little is known regarding the aggregated likelihood that at least someone present at an emergency will do something to help. The importance of establishing this aggregated intervention baseline is not only of scholarly interest, but is also the most pressing question for actual public victims—will I receive help if needed? The current paper describes the largest systematic study of real-life bystander intervention in actual public conflicts captured by surveillance cameras. Using a unique cross-national video dataset from the United Kingdom, Netherlands, and South Africa (N = 219), we show that in nine-out-of-ten public conflicts, at least one bystander, but typically several, will do something to help. We record similar likelihoods of intervention across the three national contexts, which differ greatly in levels of recorded violent crime. Finally, we find that increased bystander presence is related to a greater likelihood that someone will intervene. Taken together these findings allay the widespread fear that bystanders rarely intervene to help. We argue that it is time for psychology to change the narrative away from an absence of help and towards a new understanding of what makes intervention successful or unsuccessful.

SynopsisA description is given of a new genus of mammal-like reptile, Mirotenthes, of which a remarkably complete and well-preserved skeleton was collected in 1936 by Professor Camp of the University of California, from the late Permian deposits of the South African Karroo.Unlike the majority of Permian mammal-like reptiles, Mirotenthes was an agile form of small dimensions. Many of the skeletal characters exhibit a significant approach towards the mammalian threshold. The limb structure is very advanced and the digital formula is mammalian. The differentiation of ribs to form a definite rib-cage of mammalian type is particularly noteworthy and may indicate the presence in this genus of a mammalian respiratory mechanism.The systematic study of this complete skeleton does much to bridge the gap between the primitive basal groups of mammal-like reptiles and the advanced Triassic groups from which the mammals derive. It has been known for many years that small, fast-moving carnivorous forms were present in the late Permian fauna, but the evidence has been fragmentary. The complete skeleton described in this paper throws new light on these hitherto poorly known genera.
