RESUMEN

The Museum für Naturkunde of the Humboldt-Universität zu Berlin houses one of the most important and extensive collections of Muscidae (Diptera) in Europe as it includes more than 700 species described by Paul Stein and many others described by two other European dipterists, F. H. Loew and T. Becker. The relevance of the collection is even greater due to the excellent geographic coverage of this material. In this paper, we give a morphological and taxonomic revision of the 114 types of Coenosiini deposited in this collection. Differential diagnoses, notes on the types and photographs of some of them (habitus and labels) are provided.

RESUMEN

The morphology of the male terminalia of fourteen African species of Helina Robineau-Desvoidy, 1830 (Diptera, Muscidae) is described and illustrated: H. dorsalis (Stein, 1914); H. emdeni Pont, 1980, H. fuscibasis Emden, 1951; H. gracilior Emden, 1951; H. hirtipes metatarsalis Emden, 1951, H. juxtamedialis Emden, 1951; H. lasiopa Emden, 1951; H. mollis (Stein, 1906); H. naivashensis Emden, 1951, stat. nov. (herein raised to species rank); H. nemoralis (Stein, 1913); H. novarae (Schiner, 1868), H. penicillata Emden, 1951; H. quadruplex (Stein, 1913); and H. trinubilifera (Malloch, 1921). These species demonstrate that the terminalia can be very varied, with different shapes of sternite 5, sometimes with very strong and long setae, and a short or elongated cercal plate and surstylus that sometimes can bear spines. Some of these species also share other external characters that are unusual among Helina, such as the arrangement of the katepisternal setae as an equilateral triangle, the absence of an anterodorsal seta on mid tibia, and wings with dark clouds. Most of these species are well described in the literature, but the male terminalia have never been studied in detail. The material studied here is deposited in the Natural History Museum (BMNH), London, United Kingdom.

RESUMEN

Spilogona breviaristata sp. nov. from South Africa is described and the morphology of the male terminalia of seven African Spilogona Schnabl (Diptera, Muscidae) species are described and illustrated: Spilogona biguttata Emden, Spilogona fuscotriangulata Emden, Spilogona natalensis Zielke, Spilogona pertinisetodes Emden, Spilogona quasifasciata Emden, Spilogona semifasciata Emden and Spilogona spinipes (Bigot). The material studied is deposited in the Natural History Museum (BMNH), London, United Kingdom, and paratypes of the new species are also in the Museu Nacional, Universidade Federal do Rio de Janeiro (MNRJ), Rio de Janeiro, Brazil, and the Oxford University Museum of Natural History (OUMNH), Oxford, United Kingdom.

RESUMEN

The genus Brachygasterina Macquart is Neotropical, with six species recorded from Argentina, Chile, Ecuador and Colombia. A new species was found among an extensive unidentified muscid material from South America in the collection of the California Academy of Sciences collection (San Francisco, California, U.S.A.). Brachygasterina maculata, new species, from Santiago, Chile, is here described and illustrated, and its position in the genus Brachygasterina is discussed.

RESUMEN

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-Universitãt zu Berlin) has been examined.

Cordiluroides Albuquerque é um gênero neotropical de Coenosiinae (Muscidae), conhecido por seis espécies. O gênero é registrado pela primeira vez na Costa Rica, através de três espécies: C. listrata Albuquerque, 1954, C. insularis (Willliston, 1896) e C. bistriata (Wulp, 1896) sp. rev.. Uma chave para identificação das espécies da Costa Rica é fornecida, bem como a redescrição das três espécies e ilustrações de caracteres morfológicos e da terminália. C. bistriata e C. vittifera (Stein, 1904) são consideradas boas espécies e por isso removidas da sinonímia de C. insularis. O material-tipo de C. listrata (Museu Nacional, Rio de Janeiro), de C. insularis e C. bistriata (The Natural History Museum, London) e de C. vittifera (Museum für Naturkunde, Humboldt-Universitãt zu Berlin) foi examinado.

RESUMEN

Interpretation of the generic names Trichomorellia Stein and Cyacyrtoneura Townsend is clarified by the examination of their type species, when available, and by analysis of the literature. The following new synonymies are proposed: Dasymorellia Malloch, 1923 is a junior synonym of Trichomorellia Stein, 1918; Cyacyrtoneura cyanea Townsend, 1931 is a junior synonym of Pyrellia violacea Robineau-Desvoidy, 1830; and Cyrtoneuropsis Townsend, 1931 (preocc.) and Cyacyrtoneura Townsend, 1931 are junior synonyms of Morellia Robineau-Desvoidy, 1830. Trichomorellia boliviana Townsend, 1931 is designated type species of Trichomorellia.
