The cleptoparasitic bee genus Epeolus Latreille, 1802 is for the first time reviewed for species occurring in the Caribbean, Central America and Mexico, and a single dichotomous identification key to the females and males of species present or likely to be present in these regions is presented. A total of 25 species have been confirmed as present across the region, although another 10 likely occur south of the Mexico–United States border. Three species are newly described—E. hanusiae sp. nov., E. nomadiformis sp. nov. and E. odyneroides sp. nov.—and redescriptions are provided for species occurring exclusively south of the United States of America (species occurring north of Mexico were recently revised elsewhere) except E. danieli (Genaro, 2014) comb. nov., which was recently described. One subspecies is elevated to species level (E. obscuripes Cockerell, 1917 stat. nov.). The following five names are newly synonymized under those of four valid species: Trophocleptria schraderi Michener, 1954 syn. nov. under E. boliviensis Friese, 1908, Tro. odontothorax Michener, 1954 syn. nov. under E. claripennis Friese, 1908, E. rugosus Cockerell, 1949 syn. nov. and E. xanthurus Cockerell, 1917 syn. nov. under E. luteipennis Friese, 1916, and E. schmidti Friese, 1925 syn. nov. under E. obscuripes. A diagnosis is provided for the presumably monophyletic and almost entirely Neotropical species group originally regarded as a separate genus, Trophocleptria Holmberg, 1886. Differential diagnoses accompany the descriptions / redescriptions of Neotropical species of Epeolus, and known collection records and information about their ecology are presented.

Tungiasis is a common parasitic infection inmany parts of the world, including South and Central America and parts of Africa. It is rare in other places, such as in India and Pakistan and imported cases have been reported in Taiwan, Italy, the United States of America, etc. Our diagnosis was made based on histopathologiocal features of the parasite, which corresponds too ther reports and description of tungiasis.1-3 It was treated by surgical excision alone. The fact that the disease has never been reported in Nepal makes it difficult to diagnose clinically, but should be considered in the future. Histopathology can aid in diagnosingthis rare condition.Keywords: Nepal; tunga penetrans; tungiasis.

SARS-CoV-2 is a deadly virus that has affected human life since late 2019. Between all the countries that have reported the cases of patients with SARS-CoV-2 disease (COVID-19), the United States of America has the highest number of infected people and mortality rate. Since different states in the USA reported different numbers of patients and also death cases, analyzing the difference of SARS-CoV-2 between these states has great importance. Since the generated RNA walk from the SARS-CoV-2 genome includes complex random fluctuations that also contain information, in this study, we employ the complexity and information theories to investigate the variations of SARS-CoV-2 genome between different states in the USA for the first time. The results of our analysis showed that the fractal dimension and Shannon entropy of genome walk significantly change between different states. Based on these results, we can conclude that the SARS-CoV-2 genomic structure significantly changes between different states, which is resulted from the virus evolution. Therefore, developing a vaccine for SARS-CoV-2 is very challenging since it should be able to fight various structures of the virus in different states.

The milliped genus Abacion is summarized, and tesselatum Rafinesque, lactarium (Say), magnum (Loomis), and texense (Loomis) are recognized as valid species even though a low level of gene interchange may be occurring between tesselatum and magnum in coastal Georgia and tesselatum and lactarium in Illinois. Geographic races do not appear to be developing in any species, and all other species group names are relegated to appropriate synonymies. Abacion occurs widely in the eastern half of the United States, from the Atlantic Ocean to the central Great Plains and from the Great Lakes to southern Florida and northeastern Mexico. Species ranges overlap broadly, and instances of sympatry and syntopy are common. The species are similar anatomically, and the most reliable taxonomic characters are found on the male gonopods, particularly the configurations of the coxal processes and the distal elements of the telopodites.

Histopathology Examination

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.

Effective Buffer

On repeated occasions in the nineteenth century, Asian cholera irrupted from its traditional center in the great river basins of India and spread in pandemic waves throughout parts of Europe, North Africa, and North America. In Spain alone 600,000 deaths resulted from cholera during four great invasions (Cárdenas, 1971: 224). The United States experienced terrifying outbreaks beginning in 1832, 1849, and 1866 (Rosenberg, 1962) which also touched parts of Mexico, Central America, and the Caribbean. Initially South America escaped the onslaught. Some Brazilians speculated that the intense heat of the equator, or the vast expanse of the Atlantic ocean, somehow offered an effective buffer to the southward spread of cholera (Rego, 1872: 84). But this “sweet illusion” was shattered in 1855. Indeed the first city in Brazil struck by Asian cholera was Belém, capital of the vast northern province of Pará located astride the equator at the mouth of the Amazon river.

Three New Species

AbstractThe genus Ericydeus Pascoe (Polydrosinae: Naupactini) distributed throughout the United States of America up to Argentina is revised and a cladistic analysis including 16 species is conducted. Three new species are described: E. bahiensis, E. argentinensis and E. cupreolus. Ericydeus humeralis Hustache is synonymized under E. nigropunctatus (Chevrolat); and E. modestus viridans (Boheman) and E. modestus duodecimpunctatus (Dalla-Torre, Emden & Emden) are elevated to species rank. Other valid species are: E. hancocki (Kirby), E. schoenherri (Perty), E. sedecimpunctatus (Linnaeus), E. yucatanus (Champion), E. roseiventris (Champion), E. quadripunctatus (Champion), E. modestus (Gyllenhal), E. forreri (Champion), E. lautus (LeConte) and E. placidus (Horn). In the cladogram obtained the species from South America gather in a clade (E. argentinensis, E. sedecimpunctatus, E. nigropunctatus, E. schoenherri, E. hancocki, and E. bahiensis) and the species from Central and North America form a separate clade (E. yucatanus, E. roseiventris - E. quadripunctatus, E. cupreolus, E. viridans - E. modestus, E. duodecimpunctatus, E. forreri, E. lautus - E. placidus). The character evolution follows a southern-northern direction. The paper includes a redescription of the genus, redescriptions or descriptions of its 16 species, a dichotomous key, habitus photographs, drawings of diagnostic structures, distribution maps, a cladogram, and a discussion of the phylogeny and distribution of the genus.
