Candidate Species

Borreliae of the relapsing fever group (RFG) are heterogenous and can be divided mainly into three groups according to vectors, namely the soft-tick-borne relapsing fever (STBRF) Borreliae, the hard-tick-borne relapsing fever (HTBRF) Borreliae, the louse-borne relapsing fever (LBRF) Borreliae, and the avian relapsing fever ones. With respect to the geographical distribution, the STBRF Borreliae are further subdivided into Old World and New World strains. Except for the Avian relapsing fever group Borreliae, which cause avian spirochetosis, all the others share infectivity in humans. They are indeed the etiological agent of both endemic and epidemic forms of relapsing fever, causing high spirochaetemia and fever. Vectors are primarily soft ticks of Ornithodoros spp. in the STBRF group; hard ticks, notably Ixodes sp., Amblyomma sp., Dermacentor sp., and Rhipicephalus sp., in the HTBRF group; and the louse pediculus humanus humanus in the TBRF one. A recent hypothesis was supported for a common ancestor of RFG Borreliae, transmitted at the beginning by hard-body ticks. Accordingly, STBRF Borreliae switched to use soft-bodied ticks as a vector, which was followed by the use of lice by Borrelia recurrentis. There are also new candidate species of Borreliae, at present unclassified, which are also described in this review.

ABSTRACTThe ascaridoid nematodes with more than two uterine branches, which occur in snakes and lizards, are grouped into three genera: (1) Polydelphis (without interlabia, with four uterine branches) containing the type species, P. anoura, occuring in Old World Pythons, with P. brachycheilos as a species dubium. (2) Travassosascaris, a new genus with interlabia and with four uterine branches, with type species T. araujoi (new name for P. quadrangularis (Schneider) of Araujo, 1969) occuring in New World rattlesnakes. (3) Hexametra, (without interlabia, with six uterine branches) containing species in lizards and snakes. In lizards, H. hexametra (type species), H. applanata, H.angusticaecoides and H. rotundicaudata are tentatively differentiated. In snakes, two Hexametra species are tentatively differentiated: (1) H. boddaertii (with three synonyms) in New World pit vipers and colubrids; (2) H. quadricornis (with twenty-two synonyms) in Old World viperids, elapids and colubrids. The morphology, host range, geographical distribution, development and harmful effects of these species are discussed.

Megachile is treated here as a single genus combining Megachile with Chalicodoma. In the Americas the genus occurs from Alaska and Canada to southern Chile and Argentina, and is well represented in the tropics. Despite their economic and ecological importance as pollinators, the biology of few species has been studied in detail largely because they are difficult to identify. The 419 species in the catalogue are allocated to 28 subgenera (including 10 Old World species introduced to the region and one species dubiously recorded from the New World). Summaries of information on each species’ classification, biology and geographical distribution are given.

The geographical distribution of Smicra differs much from that of Leucospis. Unlike the latter genus, which is spread thinly and somewhat equally over the warm and temperate regions of the earth, Smicra, with very few exceptions, is limited to the New World, where there are some species in North America, many in Mexico and in the West Indies, and great abundance in the tropical parts of South America, and the genus has thus much more influence than Leucospis in regulating, by means of transfer, the increase of other insect tribes.

Morphological Characters

Eight new species of Neotropical Zanthoxylum L. (Rutaceae) are here described based upon their morphological characters. Zanthoxylum amplicalyx Reynel, which belongs to Zanthoxylum sect. Tobinia (Desv. ex Ham.) Griseb., has the largest calyx segments for its section. The others, Z. brisoferox Reynel, Z. chocoense Reynel, Z. impressocordatum Reynel, Z. magnifructum Reynel, Z. mauriifolium Reynel, Z. sambucirhachis Reynel, and Z. tingana Reynel, belong to the most speciose section, Macqueria Comm. ex Triana & Planch., and are distinguished by a variety of characters. Zanthoxylum magnifructum has the largest fruits of any species in the genus in the New World. Of the newly recognized species, four have a geographical distribution in Ecuador, three in Colombia, and one in Cuba.

AbstractMansonella ozzardi(Nematoda: Onchocercidae) is a little studied filarial nematode. This human parasite, transmitted by two families of dipteran vectors, biting midges (most of them members of the genusCulicoides) and blackflies (genusSimulium), is endemic to the Neotropical regions of the New World. With a patchy geographical distribution from southern Mexico to north-western Argentina, human infection withM. ozzardiis highly prevalent in some of the Caribbean islands, along riverine communities in the Amazon Basin, and on both sides of the border between Bolivia and Argentina. Studies conducted in Haiti between 1974 and 1984 allowed the first complete description of the adult worm and permitted clarification of the taxonomic position of this filarial species. This paper reports the known geographical distribution ofM. ozzardiin Neotropical regions of the Americas, and focuses on the current situation in Haiti where this filariasis remains a completely neglected public health problem.
