Studies of Ephydrinae (Diptera: Ephydridae), III: Revisions of Some Neotropical Genera and Species

Abstract

Mathis, Wayne N. Studies of Ephydrinae (Diptera: Ephydridae), III: Revisions of Some Neotropical Genera and Species. Smithsonian Contributions to Zoology, number 303, 50 pages, 77 figures, 1980.-The systematics phylogeny, classification, and natural history of four genera, three subgenera, and one species of a fourth subgenus of Neotropical Scatellini are revised. Other taxa of Scatellini not known to occur in the Neotropics but whose status is altered as a consequence of this study are diagnosed and discussed. One new genus, Notiocoenia, and four new species, Limnellia itatiaia, Notiocoenia acutella, N. paniculata, and N. pollinosa, are described. Calocoenia Mathis is elevated to generic status as the sister group of Paracoenia Cresson, Thiomyia Wirth is relegated to subgeneric status as the sister group of Paracoenia sensu stricto, Synhoplos Lamb and Teichomyza Macquart are consigned to subgeneric status in Scatella Robineau-Desvoidy, and Scatophila curtipennis Becker is placed in the subgenus Neoscatella Malloch of Scatella. Keys to genera, subgenera, and species, illustrations, and distribution maps are provided. OFFICIAL PUBLICATION DATE is handstamped in a limited number of initial copies and is recordel in the Institution's annual report, Smithsonian Year.

Laboratory rearing of the urine fly, Scatella (Teichomyza) fusca and observations on feeding and oviposition on pig farms

“…fusca larvae in the rearing medium mainly pupated by securing the posterior end to the exposed part of the brick, presumably because the drier environment improves survival of the flies (McPheron & Broce, 1996), but pupation also took place at the surface of the medium. Mathis (1980) reports that S. fusca adult flies are attracted to light at night. The pupae, like the eggs, mainly adhere to the solid surfaces above the liquid manure flow, and together with the larvae, they may assemble in such masses (Figure 1) as to block drains and sewage pipes (Smith, 1989).…”

Mathis (1980) reports that S. fusca adult flies are attracted to light at night. However, no such observa- tion was made during rearing, as only a few flies found their way into the lit-up hatching traps from dark rearing buckets.…”
