Taxonomy and morphology of Apsil Malloch (Diptera, Muscidae, Coenosiinae, Coenosiini) with new records, description of a new species and a key to identification

Taxonomy and morphology of Apsil Malloch (Diptera, Muscidae, Coenosiinae, Coenosiini) with new records, description of a new species and a key to identification. Apsil Malloch (Diptera, Muscidae, Coenosiinae, Coenosiini) includes 10 species, most of them described from Chile, but some also from Argentina. Five of them and one new species were found at the California Academy of Sciences collection (San Francisco, California) during the course of a project developed in that institution. Almost all material studied was collected in Chile, mainly by M. E. Irwin, during the year of 1966. Brief diagnosis of the known studied species (A. apicata Malloch, A. atripes Malloch, A. dilata Malloch, A. maculiventris Malloch (female described for the first time) and A. spatulata, Malloch), the description of A. mallochi, sp. nov. and a key for the identification of all known species are given. Color illustrations of some morphological characters make easier the recognition of the species. New geographic records were assigned.

Cordiluroides Albuquerque from Costa Rica: first records, descriptions and taxonomic changes (Diptera, Muscidae, Coenosiinae)

Cordiluroides Albuquerque is a genus of Neotropical Coenosiinae (Muscidae), known from six species. The genus is here recorded for the first time from Costa Rica, on the basis of three species: C. listrata Albuquerque, 1954, C. insularis (Willliston, 1896) and C. bistriata (Wulp, 1896) sp. rev.. We provide a key for the identification of these Costa Rican species, redescribe and illustrate their external morphological characters and terminalia. C. bistriata and C. vittifera (Stein, 1904) are both considered to be good species and are re-instated from the synonymy of C. insularis. The type material of C. listrata (Museu Nacional, Rio de Janeiro), of C. insularis and C. bistriata (The Natural History Museum, London) and of C. vittifera (Museum für Naturkunde, Humboldt-Universität zu Berlin) has been examined.

Contribuição ao conhecimento de Spilogona Schnabl: redescrição de espécies neotropicais, descrição das terminálias e chave para as espécies latino-americanas (Diptera, Muscidae, Coenosiinae)

Spilogona Schnabl (Diptera, Muscidae, Coenosiinae, Limnophorini) está representado na América Latina por oito espécies. O exame de material tipo de quatro espécies - S. golbachi Snyder, S. hirticeps (Stein), S. trichops (Stein) e S. semicinerea (Stein), a primeira depositada na Fundación e Instituto Miguel Lillo (Argentina) e as demais no Stlaatliches Museum für Tierkunde (Alemanha) permitiu a redescrição dos adultos e a descrição com ilustrações das terminálias masculinas e femininas, as três últimas, pela primeira vez.

Descriptions of new species with a key to identification of the genus Neodexiopsis Malloch (Diptera, Muscidae) in Brazil

Nine new species of Neodexiopsis Malloch from Paraná, southern Brazil, are described: Neodexiopsis cinerea sp. nov. and N. paranaensis sp. nov. from Ponta Grossa; N. facilis sp. nov., N. legitima sp. nov., N. similis sp. nov. and N. uber sp. nov. from Guarapuava; N. erecta sp. nov., N. pura sp. nov. and N. rara sp. nov. from Colombo. A key to the identification of the Brazilian species of Neodexiopsis is also presented.

First record of Coenosia attenuata Stein (Diptera, Muscidae) from Chile, with biological notes

First record of Coenosia attenuata Stein (Diptera, Muscidae) from Chile, with biological notes. Coenosia Meigen (Muscidae, Coenosiinae) species are known as predators of other insects and play an important role as potential biocontrol agents. Six species of Coenosia have been recorded in Europe preying on insects pests, one of them is Coenosia attenuata Stein. This species was recently recorded from the Neotropical Region and is herein recorded for the first time to Chile. Biological notes were included.

Neodexiopsis Malloch from Bolivia with the description of one new species (Diptera, Muscidae)

Neodexiopsis Malloch from Bolivia with the description of one new species (Diptera, Muscidae). Neodexiopsis Malloch (Diptera, Muscidae, Coenosiinae) is a very well represented genus in the Neotropical Region, known from almost 100 species. In Bolivia, it is known only from four species: N. declivis, N. incurva, N. oculata and N. recedens, all described by Stein. The study of material from South America deposited at Muséum national d'Histoire naturelle (Paris, France), enabled the description of one new species to science. A key for the recognition of the five species known to Bolivia is given.
