A new dragonfly,Austroprotolindenia jurassica (Odonata: Anisoptera), from the Upper Jurassic of Australia

Beattie, R.G. & Nel, A., June 2012. A new dragonfly, Austroprotolindenia jurassica (Odonata: Anisoptera), from the Upper Jurassic of Australia. Alcheringa, 189–193. ISSN 0311-5518.

Austroprotolindenia jurassica gen. et sp. nov., a new Mesozoic Australian dragonfly, is described from the Talbragar Fossil Fish Bed (Upper Jurassic) of eastern Australia. It shows some similarities with the Eurasian Mesozoic petalurid family Protolindeniidae, but its incomplete state of preservation prevents us assigning it to a particular anisopteran clade.

Community-based development, non-governmental organizations and social capital in post-apartheid South Africa

Community-based development strategies are gaining in credibility and acceptance in development circles internationally and notably in post-apartheid South Africa. In parallel, the concept of social capital and the role of supportive nongovernmental organizations are receiving attention as key catalytic elements in encouraging and assisting community-based initiatives. In this paper, a well-documented initiative, the Hertzog Agricultural Co-operative in Eastern Cape province, is re-examined after the passage of several years to assess the impact of social capital and the involvement of a particular non-governmental organization in ensuring the sustainability and economic survival of the project. While both elements have proved critical to the project's life-cycle, particularly in recent years, concerns over possible dependency and project sustainability exist.

A new family of ‘libelluloid’ dragonflies from the Middle Jurassic of Daohugou,northeastern China (Odonata: Anisoptera: Cavilabiata)

Nel, A. & Huang, D.Y., 8.5.2015. A new family of ‘libelluloid’ dragonflies from the Middle Jurassic of Daohugou, northeastern China (Odonata: Anisoptera: Cavilabiata). Alcheringa 39, 525–529. ISSN 0311-5518

A new well-preserved Middle Jurassic fossil of Cavilabiata is described and attributed to a new family (Daohugoulibellulidae), genus and species (Daohugoulibellula lini), from the Daohugou beds of China. Together with examples of Juralibellulidae from the same outcrop, they represent the oldest records of the Cavilabiata. The potential closest relative of the new family could be the Late Jurassic Nannogomphidae, suggesting a significant diversity of Cavilabiata during the Middle Jurassic.

Two new stem-stoneflies discovered in the Pennsylvanian Avion locality,Pas-de-Calais,France (Insecta: ‘Exopterygota’)

Schubnel, T., Perdu, L., Roques, P., Garrouste, R. & Nel, A.,26 February 2019. Two new stem-stoneflies discovered in the Pennsylvanian Avion locality, Pas-de-Calais, France (Insecta: ‘Exopterygota’). Alcheringa 43, 430–435.

Avionptera communeaui gen. et sp. nov. and Gulou oudardi sp. nov., the second and third Carboniferous representatives of the stem group Plecoptera (after G. carpenteri) are described and illustrated. A. communeaui is attributed to the Paleozoic family Fatjanopteridae, of which the only previous member was Fatjanoptera mnemonica. Based on a re-examination of the families Gulouidae and Emphylopteridae, the former family is restored to the Plecoptera stem group and the latter is transferred to the Archaeorthoptera.

South Africa's Current Transition in Temporal and Spatial Context

This article analyses South Africa's current postapartheid transition in the light of earlier transformations of its social and economic order. The first of these prior transformations is the abolition of slavery and the shift to liberal capitalism, which took place in the early nineteenth century. The second is the rapid industrialization of the late nineteenth and early twentieth centuries. Each of these transformations, as well as the current transition, is explained as being partly the outcome of a broad shift in capitalist practice, innovated in the metropoles of the global economy. Due to South Africa's situation within global economic networks, each of these shifts, at different times, raised the threat of a dislocation in South Africa's prevailing social order. However, each prior transformation and, it will be argued, the current transition, has been 'managed' by established elites so as to ensure minimal change to the overall distribution of privilege. This conservative 'management' of shifts in capitalist practice, it is suggested, has been facilitated through South African elites' historic engagement with cultural discourses circulating across a global terrain. In this article then, contemporary South Africa is located within both material and discursive networks which have historically influenced the country's distribution of privilege.     

Exceptionally well-preserved dragonflies (Insecta: Odonata) in Mexican amber

Zheng, D., Nel, A., Jarzembowski, E.A., Chang, S.-C., Zhang, H. & Wang, B., May 2018. Exceptionally well-preserved dragonflies (Insecta: Odonata) in Mexican amber. Alcheringa xxx, xxx–xxx.

Dragonflies (odonatans) are comparatively rare as amber inclusions, and most are not well preserved on account of their size. Here, we report a single piece of Mexican amber with one complete dragonfly and two damselflies. The dragonfly is attributed to the extant gomphid Erpetogomphus Selys Longchamps, and the damselflies belong to the extant coenagrionid Argia Rambur. Both genera are nowadays distributed widely in Mexico. The new discovery dates the origins of these two genera to the Miocene at least.

A new,extraordinary ‘damselfly-like’ Odonatoptera from the Pennsylvanian of the Avion locality in Pas-de-Calais,France (Insecta: ‘Exopterygota’)

Nel, A., Roques, P., Prokop, J., & Garrouste, R., 11 September 2018. A new, extraordinary ‘damselfly-like’ Odonatoptera from the Pennsylvanian of the Avion locality in Pas-de-Calais, France (Insecta: ‘Exopterygota’). Alcheringa 43, 241–245. ISSN 0311-5518.

Enigmaptera magnifica gen. et sp. nov., type genus and species of the new odonatopteran family Enigmapteridae, is described from the Moscovian of Avion (northern France). It is the sister group of the major clade Neodonatoptera, placed together in the new clade Paneodonatoptera. Its wing venation has characters never found in other Odonatoptera. It is a further case of convergent wing petiolation in this superorder. Enigmaptera magnifica, like the protozygopteran Jacquesoudardia magnifica from the same outcrop, probably lived like the extant damselflies along the shores of lakes and rivers, hunting the small insects found in the same deposits. These discoveries show that very small insects were significant elements of the entomofaunal diversity and trophic chains of the Late Carboniferous ecosystems.
