The first worldwide revision of the wasp genus Ufens Girault, 1911 (Hymenoptera: Trichogrammatidae: Oligositinae) is presented. Ufens is known to parasitize primarily hemipteran eggs and is a cosmopolitan genus most common in temperate and semi-arid regions such as the southwestern United States and Australia. Forty-three species are recognized here. Included in the revision are five species formerly in the genus Ufensia, herein synonymized, and 32 new species. In addition, seven species are removed from Ufens and placed in renewed combination in Mirufens. Because thirteen nominal species remain unidentifiable they are treated as nomina dubia. A worldwide key to species is provided. A preliminary phylogenetic hypothesis is presented utilizing both molecular and morphological data in maximum parsimony analysis. Molecular data, however, are limited to twelve of the recognized species. Thirty-seven morphological characters were utilized, both alone and together with molecular data. Due to greater confidence in molecular results and overall lack of resolution, the results of the paired-down molecular plus morphological analysis were utilized as a backbone for analyzing the complete morphological data set. Overall, results are inconclusive, with few relationships consistently recovered. There does appear to be a Holarctic clade, but even this result is tenuous.
Frederik van Zyl Slabbert was a man on a mission, whether as an academic, an opposition politician, a democratic facilitator or a businessman. Perhaps this was a product of his restless, probing intellect, or his early ambition to become a dominee in the Dutch Reformed Church. When he famously led a delegation of leading Afrikaners to Dakar in 1987 to meet the exiled ANC, many saw it as a breakthrough, while others felt he had been taken in. And yet his reputation – for honesty, integrity, wit and courage – still towers above many of his contemporaries. Slabbert was always different. As an academic turned politician, the charismatic Slabbert brought unusual intellectual rigour to Parliament, transforming the upstart Progressive Federal Party into a force that challenged the National Party government. But disillusioned by the paralysis of formal white politics, and by the growing polarisation of South African society, he resigned in 1986 to explore democratic alternatives to the impasse into which the country had been led under apartheid. Largely side-lined during the democratic transition, he continued to pursue a broad range of initiatives aimed at building democracy, empowering black South Africans and transforming the economy. Albert Grundlingh's penetrating biographical study offers sharp insights into the thinking and motivation of this most unlikely politician. Concise but wide-ranging, Slabbert: Man on a Mission provides new perspectives on a figure who even today remains something of an enigma.
