O gênero Anthidium Fabricius na América do Sul: chave para as espécies, notas descritivas e de distribuição geográfica (Hymenoptera, Megachilidae, Anthidiini)

The genus Anthidium Fabricius in the South America: key for the species, descriptive notes, and geographical distribution (Hymenoptera, Megachilidae, Anthidiini). The Anthidiini, in South America, is represented by a single genus Anthidium Fabricius, 1804 (type-species: Apis manicata Linnaeus, 1758). Thirty nine species are treated in this paper, as follows: Anthidium alsinai Urban, 2001; A. andinum Joergensen, 1912; A. anurospilum Moure, 1957 nom. reval. (formerly = A. espinosai Ruiz, 1938); A. atricaudum Cockerell, 1926; A. aymara Toro & Rodríguez, 1998; A. chilense Spinola, 1851; A. chubuti Cockerell, 1910; A. colliguayanum Toro & Rojas, 1970; A. cuzcoense Schrottky, 1910; A. danieli Urban, 2001; A. decaspilum Moure, 1957; A. deceptum Smith, 1879; A. edwini Ruiz, 1935; A. espinosai Ruiz, 1938; A. falsificum Moure, 1957; A. friesei Cockerell, 1911; A. funereum Schletterer, 1890; A. garleppi Schrottky, 1910 = A. matucanense Cockerell, 1914 syn. nov.; A. gayi Spinola, 1851; A. igori Urban, 2001; A. larocai Urban, 1997; A. latum Schrottky, 1902; A. luizae Urban, 2001; A. manicatum (Linnaeus, 1758); A. masunariae Urban, 2001; A. nigerrimum Schrottky, 1910; A. paitense Cockerell, 1926; A. penai Moure, 1957; A. peruvianum Schrottky, 1910; A. rafaeli Urban, 2001; A. rozeni Urban, 2001; A. rubripes Friese, 1908 = A. boliviense Friese, 1920 syn. nov. = A. adriani Ruiz, 1935 syn. nov. = A. kuscheli Moure, 1957 syn. nov.; A. sanguinicaudum Schwarz, 1933; A. sertanicola Moure & Urban, 1964; A. tarsoi Urban, 2001; A. toro Urban. 2001; A. vigintiduopunctatum Friese, 1904; A. vigintipunctatum Friese, 1908, and A. weyrauchi Schwarz, 1943. Some taxonomic comments are made for each species, and new data on geographic distribution are also given. The females of A. andinum, A. igori, A. rozeni and the male of A. anurospilum are described for the first time. Identification keys (for males and females), as well as illustrations for almost all species, are provided.

Distribuição temporal de imaturos de Odonata (Insecta) associados a Eichhornia azurea (Kunth) na Lagoa do Camargo, Rio Paranapanema, São Paulo

Os objetivos deste trabalho foram registrar a abundância e a riqueza de Odonata associada a Eichhornia azurea, durante o período de março de 2004 a março de 2005, na Lagoa do Camargo, lateral ao Rio Paranapanema - São Paulo, após um pulso de inundação extraordinário e também investigar os fatores ambientais determinantes na distribuição da abundância de Odonata. As maiores abundâncias e riquezas ocorreram na estação seca, sendo que Coenagrionidae foi a família mais abundante e com a maior riqueza de gêneros de todo o período estudado. Esta alta abundância possivelmente ocorreu devido a seu comportamento, como postura dos ovos dentro do tecido das macrófitas e hábito escalador. Aeshnidae e Libellulidae apresentaram baixa abundância principalmente na estação seca. Os principais fatores ambientais que afetaram a distribuição da abundância de Odonata foram a temperatura de superfície da água, a pluviosidade e a biomassa de E. azurea.

A new species of Lioptilodes Zimmerman (Lepidoptera, Pterophoridae) from northern Chile

Male and female adults of a new species of Lioptilodes Zimmerman (Lepidoptera, Pterophoridae) are described and illustrated. Immature stages are associated with Baccharis scandens (Ruiz & Pav.) Pers. (Asteraceae). The species was collected in two localities of northern Chile: near sea level in the Azapa valley, in the coastal desert of Arica Province and at 3000 m elevation in Socoroma, Parinacota Province.

Insects associated with exposed decomposing bodies in the Colombian Andean Coffee Region

In Colombia, mainly classic forensic medicine methods were used to clarify crimes until 2004. However, other disciplines, including forensic entomology, started to be considered only after the New Accusatory System introduction in Bogotá and the Coffee Region in 2005. In order to provide tools for obtaining evidentiary material elements in judicial trials, it is presented here the succession of insects throughout the decomposition process of an exposed carcass of Sus scrofa Linnaeus 1758 (Suidae) and the Occurrence Matrix of colonizing species. This process was evaluated under ambient conditions in the Andean rural area of the city of Pereira, in the Mundo Nuevo district, located in a pre-montane Wet Forest area, from October to November 2006. A sampling period of 27 days and 3198 individuals were collected. We found these colonizing species in the following stages of decomposition: Lucilia eximia (Wiedemann, 1819) fresh; Hemilucilia semidiaphana (Rondani, 1850), Oxelytrum discicolle (Brullé, 1840), and Cochliomyia macellaria (Fabricius 1775) bloated; Chrysomya albiceps (Wiedemann 1819), Compsomyiops verena (Walker, 1849), Ophyra aenescens (Wiedemann, 1830) and Musca domestica Linnaeus, 1758 active; Fannia sp. advanced and Stearibia nigriceps (Meigen, 1826) remains. This study provides support tools to define the Post Mortem Interval that may be used by experts from government institutions and laboratories officially accredited.
