We review eleven Astrotischeria Puplesis & Diškus (Lepidoptera: Tischeriidae) species which possess a novel character for the Tischeriidae family: a highly modified valva of the male genitalia with one ventral and two dorsal lobes (or processes). The species are distributed in the Americas, including the USA, Caribbean (St. Thomas), Central America (Belize, Guatemala and Honduras), and South America (Ecuador, Bolivia, and Brazil). Species for which the biology has been studied are associated with host plants from Asteroidea of the Asteraceae family. The following seven species are described as new: Astrotischeria trilobata Diškus & Stonis, sp. nov., A. amazonica Diškus & Stonis, sp. nov., A. maya Diškus & Stonis, sp. nov., A. selvica Diškus, Carvalho-Filho & Stonis, sp. nov., A. casila Diškus & Stonis, sp. nov., A. onae Diškus & Stonis, sp. nov., and A. furcata Stonis & Diškus, sp. nov. A new informal species unit, the A. trilobata group, is designated for diagnostic purposes despite some doubts about monophyly of the group. Astrotischeria longeciliata (Frey & Boll) is synonymized here with the North American A. helianthi (Frey & Boll), a species not belonging to the A. trilobata group, syn. nov. For the first time, a method of rearing of adults from mining larvae, specifically adopted for Tischeriidae, is detailed. All species treated in the paper are illustrated with photographs or drawings of the adults, male genitalia, and, if available, the female genitalia, leaf mines and habitats. A distribution map for the species of the A. trilobata group and a scheme of the trophic relationships of the global Tischeriidae fauna are also provided.

Rhinoscleroma is a chronic, slowly progressive granulomatous bacterial infection that is endemic to the tropical world, namely, Central America and Africa. It is occasionally seen in the United States of America (USA). It predominately affects the nasal mucosa but can also involve the rest of the upper respiratory tract. The well-known causative agent for rhinoscleroma is the bacteriumKlebsiella rhinoscleromatis, a subspecies ofKlebsiella pneumoniae. However,Klebsiella ozaenaecan also, albeit very rarely, cause rhinoscleroma. The diagnosis is confirmed by histopathology examination that shows the characteristic Mikulicz cells, considered pathognomonic for this infection. We report a patient with histologically proven rhinoscleroma with pharyngolaryngeal involvement in whom cultures yieldedKlebsiella ozaenae. To the best of our knowledge, only two cases of rhinoscleroma due toKlebsiella ozaenaehave been reported in the literature to date. Our case illustrates the importance of recognizing this infection in a nonendemic setting such as the USA. A lack of awareness and a delay in the diagnosis of this disease can lead to complications including upper airway obstruction, physical deformity, and, rarely, sepsis. In addition, it must be remembered that the treatment of rhinoscleroma is challenging and requires a prolonged course of antibiotics to achieve a definite cure and avoid relapses.

Chagas disease (CD), caused by the protozoan Trypanosoma cruzi, is a public health concern, mainly among countries in South and Central America. However, despite the large number of immigrants from endemic countries living in the USA, awareness of CD is poor in the medical community, and therefore it is significantly underdiagnosed. To avoid the catastrophic cardiac complications of CD and to prevent maternal–fetal transmission, widespread educational programs highlighting the need for diagnosis are urgently needed.

This article analyses attempts to regulate the access to arms in Central America from the beginning of the World War I to the end of the 1920s. During these years, the USA was not only the politically and economically dominant force in the region – they were also the main provider of weapons. In a region where societies were reshaped by the integration into a global economy, political groups depended on the access to weapons to enforce their claims for power. This gave the US government the possibility to use arms exports as well as arms embargos to shape politics in the region. Within this setting, arms control through international law became a contested subject. The First World War boosted international debates about disarmament. The Wilson administration joined these debates with proposals, which would have enabled Washington to better control the flow of arms into the Western Hemisphere. Central American governments, on the other hand, joined disarmament negotiations in Geneva to shape international law in a way to restrict Washington’s influence in the region and to ensure equal treatment at the international level. The impact of this conflict was not limited to the Western Hemisphere, and it left its imprint on European disarmament policies. Thus, this article reveals how international arms control was inscribed at the same time in imperial and anti-imperial agendas in a region with formally sovereign states.

This article is an attempt to critically analyze the policy of the 45th President of the United States Donald Trump regarding the southern border of the USA with Mexico. The paper analyzes the approach of Washington under the administration of D. Trump to the problem of the joint border between USA and Mexico, as well as conducts a comprehensive assessment of the main programs underlying the most pressing changes in D. Trumps policy in this area. In particular, the paper focuses on the structure of migration flows between 2017 and 2019, as well as on the reasons behind those changes. The author looks at the root causes of the unprecedented increase in the flow of potential migrants and refugees, and correlates them with the ongoing political, economic and humanitarian crises in the Central American sub-region. An important focus is given to the increasing role of Mexico in the settlement of this issue, as well as to the potential impact of such cooperation between the authorities of the United States and Mexico on the situation in Central America and Latin America in general. The significance of this paper is determined by the objective necessity of academic evaluation of the Donald Trumps administration impact on the United States governmental and foreign policy course. The author argues that the approach of the 45th president of the United States regarding traditionally sensitive issues like US - Mexico border control and migration has been mostly based on coercive tactics with obvious disregard towards social basis and root-causes of the issue at hand. One of the most distinguished traits of this approach is the practice of outsourcing managing the problem of refugees from Central America to the border-country, which in this specific case is Mexico.

Changes to the taxonomy of North and Central America Leptohyphes (Ephemeroptera: Leptohyphidae) include the following. Leptohyphes ferruginus and L. apache are revalidated. The adult stage of L. ferruginus is diagnosed based upon subimagos and a reared female adult and a partially emerged male adult. Leptohyphes piraticus is placed as a junior synonym of L. ferruginus. Leptohyphes vulturnus and L. zelus are shown to be junior synonyms of L. zalope. Leptohyphes hispidus, L. lumas, L. spiculatus, and L. succinus are placed as junior synonyms of L. apache. Leptohyphes castaneus, L. tarsos, and L. consortis are placed as junior synonyms of L. sabinas. Leptohyphes brunneus is placed as a junior synonym of L. musseri. Leptohyphes lestes is newly reported from the USA. Numerous problems and errors asssociated with original descriptions of Leptohyphes species are discussed. A taxonomic key is presented to all known larval stages of North and Central American species of Leptohyphes.

AbstractEvidence has been slowly accumulating that the urban home gardens of immigrants or transnational migrants in the USA conserve food plant diversity with roots in the developing world. Published species lists for home gardens indicate that, at least at the species level, this diversity is not novel but consists of widely grown, culturally important plant species that are also available through the horticultural trade. In 2018, we returned to the home garden of a Mexican-origin household in Chicago and confirmed the identity of a plant provisionally identified as Jaltomata darcyana during an earlier inventory of the garden. A recently named species of Central America, J. darcyana has not been previously recorded in cultivation. Collection of this species from a Chicago garden suggests that urban gardens may harbor other novel species awaiting documentation by urban ecologists and botanists.

Abstract M. zapota, commonly known as sapodilla, is an evergreen tree, 5-20 m tall, with a round, dense crown. Its native range encompasses Central America, Mexico and the West Indies, but it is now widely cultivated for its fruit to a greater or lesser extent in tropical and subtropical lowlands worldwide. It is an important fruit tree all over South-East Asia, grown in home gardens, orchards and plantations. The largest producers of sapodilla fruit are India, Thailand, the Philippines and Malaysia, but it is also grown commercially elsewhere in Asia, South and Central America, and Florida in the USA. Escapes from plantations have caused the species to be classed as a moderately invasive weed in the tropics (Binggeli et al., 1998), although in the USA it is of particular concern in southern and central Florida, where it is classed as a Category I invasive displacing the native flora (Florida Exotic Pest Plant Council, 2001). It is also listed as invasive in Trinidad and Tobago (Trinidad and Tobago Biodiversity, 2017). Trees cast dense shade, making it difficult for other plants to survive in the understorey. Seedlings also grow very densely, inhibiting the establishment of native plant species.
