Gêneros e espécies novos de Mesembrinellinae (Diptera, Calliphoridae) da Costa Rica e Venezuela

Abstract

São descritos os seguintes novos táxons: Henriquella gen. nov. (espécie-tipo Mesembrinella spicata da Costa Rica, La Suiza), Giovanella gen. nov. com Giovanella bolivar sp. nov. (espécie-tipo) da Venezuela, Bolivar e Huascaromusca lara sp. nov. da Venezuela, Lara. Mesembrinella spicata Aldrich, 1925 anteriormente considerada como sinonímo de Calliphora xanthorrhina Bigot, 1887, é restabelecida e transferida para Henriquella gen. nov., tornando-se Henriquella spicata (Aldrich, 1925) sp. rev., comb. nov. Ilustrações dos holótipos, incluindo as respectivas terminálias, também são fornecidas.

Checklist and distribution maps of the blow flies of Venezuela (Diptera, Calliphoridae, Mesembrinellidae)

“…These records were not unexpected, as these species have been found in other South American countries: Chrysomya putoria in Argentina, Bolivia, Brazil, Colombia, Ecuador, Paraguay and Peru (Baumgartner 1988, Wolff and Kosmann 2016), Mesembrinella spicata in Costa Rica and Colombia (Bonatto and Marinoni 2005, Kosmann et al 2013), and Mesembrinella umbrosa in Bolivia, Colombia and Ecuador (Guimarães 1977, Peris and Mariluis 1984, Wolff and Kosmann 2016). …”

“…Mariluis and Peris (1984) and Whitworth (2012) for Calliphorinae; Mariluis and Peris (1984), Mariluis et al (1994b), Rognes (1994) and Whitworth (2010, 2014) for Luciliinae; Dear (1985), González-Mora et al (1998), Mariluis et al (1994a), Rognes and Paterson (2005), Whitworth (2010) and Grella et al (2015) for Chrysomyinae, and Dear (1979) for Toxotarsinae. In the case of Mesembrinellidae the keys of Guimarães (1977), Bonatto and Marinoni (2005) and Wolff et al (2014) were used. The dissection and study of male terminalia were carried out following Whitworth (2006, 2010).…”

Review of Thompsoniella Guimarães with description of a new species from Colombia (Diptera, Calliphoridae, Mesembrinellinae)

“…Terminology follows McAlpine (1981) and Bonatto & Marinoni (2005). Body length was measured from the frons to the apex of the abdomen, and wing length from the alar sclerite to the wing apex.…”

A new species of Giovanella Bonatto (Diptera, Calliphoridae, Mesembrinellinae) from Colombia

“…The morphological description used in the diagnosis and description of the new species follows McAlpine (1981). Abbreviations follow two sources, McAlpine (1981), and Bonatto & Marinoni (2005). The measures 'head width' and 'frons width' follow Whitworth (2006), in which the frons width is taken from the narrowest point.…”

“…Giovanella Bonatto, 2005: 884 Diagnosis. According to Bonatto & Marinoni (2005), this genus can be identified by the following combination of characters: anterior spiracle with buttonhole-like opening and no dorsal dilatation; acrostichal setae absent; intra-alar seta 0:1; hyaline wings with strongly developed maculae from base to R 2+3 ; T5 with no discal setae. We consider that character T5 with no discal setae, should be amended, since in the examined specimens the T5 possesses discal setae (little differentiated), a condition which approaches Giovanella to Huscaromusca.…”
