Abstract:

The crown wasps, family Stephanidae, are generally believed to occupy a distinguished position as putative relicts of the earliest-diverging lineage of apocritan Hymenoptera (e.g., Sharkey et al., 2012; Mao et al., 2015). More recent analyses have cast some confusion over this hypothesis, with the family instead appearing closer to the Evanioidea or even Trigonalyoidea (Peters et al., 2017; Tang et al., 2019). From most analyses it is clear that the family extends well into the Cretaceous, with crown-group Stephanidae estimated to have appeared by at least the Early Cretaceous and a purported ghost-stem lineage extending into the Early Jurassic or even latest Triassic (Tang et al., 2019). At least parts of such a hypothesis are consistent with the number of mid-Cretaceous fossils representing a variety of crown wasps, including species of both the plesiomorphic subfamily Schlettereriinae as well as putative Stephaninae (Engel & Grimaldi, 2004; Engel et al., 2013; Engel & Huang, 2017; Li et al., 2017). Unfortunately, while such fossil occurrences are of considerable interest, the total available record of fossil crown wasps is poor, with most species documented from the Palaeogene (Engel, 2005; Engel & Ortega-Blanco, 2008), and hitherto only four species from the Late Cretaceous. Given the potentially long gap between the first divergence of the lineage and the appearance of the crown group (Tang et al., 2019), it is precisely for such a group that early diverging stem groups would be of considerable value in resolving relationships and documenting the appearance of apomorphies within the clade. Extensive study of Early Cretaceous and Jurassic deposits for stem-group Stephanidae is necessary in order to provide direct evidence into the early evolution of this critical family of the Euhymenoptera.

Abstract:

The fossil crown wasp <em>Electrostephanus petiolatus</em> Brues <strong>comb. rev. </strong>(Stephanidae, Electrostephaninae) is redescribed from a single male preserved in middle Eocene Baltic Amber. The holotype was lost or destroyed around the time of World War II and subsequent interpretations of its identity have been based solely on the brief descriptive comments provided by Brues in his original account. The new specimen matches the original description and illustration provided by Brues in every detail and we hereby consider them to be conspecific, selecting the specimen as a neotype for the purpose of stabilizing the nomenclature for this fossil species. This neotype exhibits a free first metasomal tergum and sternum, contrary to the assertion of previous workers who indicated these to be fused. Accordingly, does indeed belong to the genus <em>Electrostephanus</em> Brues rather than to <em>Denaeostephanus</em> Engel & Grimaldi (Stephaninae). <em>Electrostephanus petiolatus</em> is transferred to a new subgenus, <em>Electrostephanodes</em> <strong>n. subgen.</strong>, based on its elongate pseudo-petiole and slender gaster, but may eventually warrant generic status as the phylogenetic placement of these fossil lineages continues to be clarified. A revised key to the Baltic amber crown wasps is provided.

Abstract:

The ensign wasps, family Evaniidae, are an immediately distinctive family of parasitoid Hymenoptera, characterized by the reduced metasomal gaster attached high to the mesosoma via a short petiolate first metasomal segment. Species are, where known, parasitoids of roach oothecae. Among the approximately 20 extant genera, the genus Evaniella Bradley, 1905 is a relatively common and widespread group, found throughout the New World and with approximately 75 described extant species (Deans, 2005). In fact, Evaniella is the most widespread New World genus of ensign wasps. Given this, it is remarkable that species of Evaniella should be found in the Eocene of Europe (vide infra), demonstrating a once greater distribution relative to today. Naturally, however, this presumes that the fossil species belong to the crown group of the genus and that the lineage is monophyletic. Monophyly of Evaniella has been supported in recent phylogenetic estimates (e.g., Sharanowski et al., 2019) but fossil species have yet to be included in such analyses for the family.

Abstract:

Abstract Eucalypts spp., are the most popular hardwood timber species in the world, indigenous to Australia, Indonesia, the Philippines, Timor, and New Guinea. Distribution is attributable to their exceptionally high ability to adapt to diverse ecological conditions and the substantially varying products and services they offer. Leptocybe invasa and Ophelimus maskelli are serious pests causing damage to eucalypt plantations in Tanzania. Due to limited knowledge and literature, a study assessed the infestation status and damages of two gall inducers on three government plantations, namely Korogwe, North Ruvu, and Morogoro forests planted with several Eucalypt species, including E. tereticornis and hybrids of E. grandis x E. camadulensis, from October 2021 to April 2022, through assessments of percentage of infested leaves in three crown parts, the association between stand elevations and the infestation magnitude and damage index. Microsoft Excel and Minitab 19 statistical software were used to analyze the data. Results showed positive correlations between wasp infestations and stand altitude among eucalypt germplasms. Clonal hybrids were more infested. The middle crown part was highly infested, followed by the lower crown part at p= 0.880 and p= 0.641 respectively. L.invasa had a higher invasive capacity than O. maskelli. Control efforts should focus on biological control and greenhouse-gall screening to get resistant genotypes. Nevertheless, mass trapping using a yellow sticky trap and a cattle stable can be used for monitoring the pest population immediately.

Abstract:

Abstract Crows and flatterers are compared in an ancient Greek saying because of their harmfulness and damage to human beings. The saying «it is better to fall amongst crows than flatterers» is attributed to the Cynic seem philosopher Antisthenes of Athens on the basis of several literary sources. All these seem to go back to Cynic doxography and ethics, relying on the Stoic thinker Hecaton of Rhodes. Previous witnesses are not extant, but a reference to the saying could possibly be found in Aristophanes’ Wasps. Indeed, Wasps 42–46 not only features the wordplay κόραξ/κόλαξ as a speech defect of Alcibiades, which seems to be rather a comic device, but also hints at a link between the crow and the flatterer. Performed in 422, before Antisthenes’ teaching as a Cynic, Aristophanes’ Wasps could represent the first literary attestation of the saying on crows and flatterers, which probably went back to the Greek sapiential heritage.

Abstract:

Racism has plagued the United States since its inception. The underside of American history is filled with the reality of racism—the decimation and removal of the Indians, slavery, Jim Crow, internment camps for Japanese Americans, the crime of driving while black, and border patrols, to name some examples. This set covers the period from colonial times until today and all the groups discriminated against at one time or another: Arabs and Muslims, who are the most recent targets, blacks, Asians, the indigenous, Latinos, European immigrants, and Jews. It is the first work to explore the magnitude of the explosive issue and does so in a non-inflammatory manner. More than 450 essay entries present key terms, organizations, movements, incidents, forums, texts, individuals, legislation, theories, and the like. The wide range of entries will facilitate cross-disciplinary reading and research for high school and higher education students and the general reader. As an authoritative ready-reference, it will be crucial for understanding of the minority groups and their experiences with the dominant culture. Most entries contain suggestions for further reading. A timeline, photos, and a host of primary documents uomplement the entries.

Abstract:

Abstract Acanthaster planci was virtually unknown by coral—reef scientists when Jack Barnes published a short paper in Australian Natural History entitled “The Crown of Thorns Starfish as a Destroyer of Coral.” 1 Barnes told of how he had come to know it. A medical doctor and naturalist, he had an interest in poisonous marine animals and he was well—known for alerting the public to the dangers of the extremely venomous “sea wasp” or box jellyfish. In the late 1950s, he had become curious about reports of the existence of a large, spiny “stinging” starfish in Queensland waters. But sightings of it were infrequent and he had given up hope of ever seeing one. Even experienced divers considered the seastar a great rarity.

Abstract:

In this thought-provoking chapter, the author explores the concept of psychological inflexibility, highlighting its presence not only in far-right and far-left ideologies but also in woke politics and neoliberalism. So the author delves into the dangerous consequences of inflexible commitment to ideas that prioritise political or economic gain over ethical considerations, perpetuating inequalities and injustices. It also means a critique of the abuse of intersectionality theory and the creation of a human pyramid that transvalues Jim Crow WASP America. The author concludes by cautioning against the narrow definition of morality and the dangers of technological and financial moguls leading the way in moral governance. Instead, lesser social and economic stakeholders should take the lead in shaping a win-win deal before the present political complexity and geopolitical stage.
