Abstract There is little published information on this plant pathogenic fungus, which is limited to parts of North, Central and South America. It infects Rubus spp., which exist in other regions of the world with similar environmental conditions, therefore this species may pose a threat to native or agricultural plants if introduced.

Eight species of Horistonotus Candèze (1860), from states of Alagoas and Sergipe, are described and illustrated and a provisional identification key for all Brazilian species of this genus is provided. The described species were collected in the Caatinga, semi-desert tropical woodland, in the Northeastern Region of Brazil. The genus Horistonotus is very numerous with more than a hundred species, distributed throughout of North, Central and South America.

Single Genus

This group was recognized as a sub-family by Newman as early as 1834, and as a distinct family by Haliday in 1839. It is represented at present by a single genus, Oryssus, Latr., which is apparenrly the stem from whence some of the parasitic Hymenoptera originated; i. e., the Megalyridae, Stephanidae, etc.I have now, however, the pleasure of indicating below another genus, indigenous to Africa.Although comparatively few species are described in the group, it yet appears to be widely distributed, species having been found in North, Central and South America, Europe, Africa, Asia and Aru, in the Malay Archipelago.

Basaltic Lavas

A complex composed of ultrabasic and basaltic lavas, chert, arkose, and conglomerate was assembled in the coast of north-central Chile (lat. 30°30′–31°S) prior to 200 Ma. The character of, and relationships between, the rock formations exposed here are consistent with an autochthonous evolution of this part of Chile in the last 200 Ma. Three major episodes of deformation and metamorphism have been observed in this area. The first episode (F1) produced a compositional layering (S1) and amphibolite-facies metamorphism coeval with the intrusion of an extensive igneous complex between 220 and 200 Ma. A second episode of deformation (F2) locally formed reverse faults and tight, recumbent folds in S1. Units in which F2 folds are well developed yield K–Ar and Rb–Sr ages between 163 and 140 Ma. At between 140 and 126 Ma, upright, open to tight folds (F3) formed with sharp hinges and axial planes that strike north and dip steeply east. Structures of similar age, style, and orientation have been reported as far south as Tierra del Fuego. The timing of the F3 deformation appears to correspond to the opening of the South Atlantic Ocean and accelerated westward motion of South America.

Background. AAT deficiency is not a rare disease, but one of the most common congenital disorders increasing susceptibility of individuals with this deficiency to both lung and liver disease as well as other several adverse health effects. Studies to develop accurate estimates of the magnitude of this genetic disorder in any given country is critical for the development of screening programs for detection, diagnosis, and treatment of those individuals and/or families at risk. In the present study, estimates of the prevalence of the two major deficiency alleles PI S and PI Z were estimated for 25 countries in the Caribbean and North, Central, and South America to supplement our previous studies on 69 countries worldwide. Method. Using data on the prevalence of the two most common deficiency alleles PI S and PIZ in the mother countries that provided the majority of immigrants to these 25 countries, as well as genetic epidemiological studies on various genetic subgroups indigenous to the Caribbean and North, Central and South America it was possible to develop new formulas to estimate the numbers in each of five phenotypic classes, namely PI MS, PI MZ, PI SS, PI SZ and PI ZZ for each country. Results. When these 25 countries were grouped into six different geographic regions, the present study demonstrated striking differences when comparisons were made in numeric tables, maps and figures. Highly significant numbers of individuals at risk for AAT Deficiency were found in both the European, Mestizo and Mulatto populations for most of the 25 countries studied in the Caribbean and North, Central and South America. Conclusions. Our studies demonstrated striking differences in the prevalence of both the PIS and PIZ alleles among these 25 countries in the Caribbean and North, Central and South America and significant numbers of individuals at risk for adverse health effects associated with AAT Deficiency in a given country. When these data are added to the results from our earlier studies on 69 countries, we now have data on AAT Deficiency in 94 of the 193 countries worldwide listed in the CIA FactBook.

The myrmecophilous genus Hippeutister Reichensperger, 1935, contains six species, known from scattered localities in North, Central and South America. Two of these, H. californicus n. sp. and H. solisi n. sp. are newly described herein. The other four are H. manicatus (Lewis) (=H. solenopsidis Reichensperger, syn. nov.), H. plaumanni Reichensperger, H. castaneus (Lewis), and H. amabilis (Wenzel). The genus is likely monophyletic, and is easily recognized by the presence of a very broad prosternal keel, which is deeply triangularly incised at the base. Species of Hippeutister are unusual among hetaeriine Histeridae in their occurrence in the nests of fire ants (Solenopsis spp.)
