Abstract The pupal case of Mallophora atra Macquart from South America is described, illustrated, and compared with the South American species M. media Clements and Bennett, M. ruficauda (Wiedemann), and M. sylveirii Macquart, and the North American species M. bomboides (Wiedemann), M. fautrix Osten Sacken, M. leschenaulti Macquart, and M. orcina (Wiedemann).

Abstract. The pupal case of the Palearctic robber fly Andrenosoma atrum (Linnaeus) is described, illustrated, and compared with those of Andrenosoma albopilosum Villeneuve and Andrenosoma bayardi Séguy. A key to the pupal cases of these three species is provided.

Adult Diptera from Ozark Caves

Abstract The Diptera fauna of Ozark caves is fairly typical of that found elsewhere in the United States east of the Great Plains. The sphaerocerid Spelobia tenebrarum is the only troglobitic dipteran found in Ozark caves. Probable troglophiles include the mycetophilid Macrocera nobilis, the psychodids Psychoda spp., and the phorid Megaselia cavernicola. The tipulids commonly found in Ozark caves, such as Dactylolabis montana, Dolichopeza spp. and Limonia spp. are probably all trogloxenes, as are the Trichoceridae and Heleomyzidae. The mycetophilids, Exechiopsis umbratica and Rymosia sp., and the culicids are among the most common cave dipterans in the study area. The culicids overwinter in caves and other protected places; they are properly classified as trogloxenes. The main sources of food for cave Diptera are other insects, carrion, guano, and allochthanous plant debris.

Review and analysis of information on the biology and morphology of immature stages of robber flies (Diptera: Asilidae).

Recent publications on the immature stages of robber flies (Asilidae) are reviewed and listed for the 14 currently recognized subfamilies (Asilinae, Bathypogoninae, Brachyrhopalinae, Dasypogoninae, Dioctriinae, Laphriinae, Leptogastrinae, Ommatiinae, Phellinae, Stenopogoninae, Stichopogoninae, Tillobromatinae, Trigonomiminae, and Willistonininae). For the Phellinae there are only limited data on the pupal cases, and for the Tillobromatinae there are only limited data on the eggs (potential oviposition site in soil) and pupal cases. The recent literature is compared with pertinent pre-1972 publications.

THE GENUS ATOMOSIA MACQUART (DIPTERA: ASILIDAE) IN NORTH AMERICA NORTH OF MEXICO

Abstract Atomosia arkansensis, new species, is described from specimens collected in blackland prairie in southern Arkansas, and Atomosia tibialis is reported the first time from North America north of Mexico. A new key to Nearctic Atomosia species is presented. Atomosia melanopogon and A. mucida are noted to be sexually dimorphic. In addition to more standard characters, the open or closed condition of cell r5 and the length of the pedicel and flagellum relative to the length of the scape are used to distinguish similar species. Lectotypes are designated for Atomosia mucida, Atomosia puella, and Atomosia sayii. Atomosia echemon is synonymized with A. puella (new synonymy), and A. mucidoides is synonymized with A. sayii (new synonymy).

Revision of Nearctic Stichopogon Species (Diptera: Asilidae) with White-Banded Abdomens, Including Description of Stichopogon Venturiensis, New Species, from Coastal California

Abstract Nearctic Stichopogon species with white-banded abdomens are reviewed. Stichopogon venturiensis, new species, is described from the Pacific coast in Santa Barbara, Ventura, and Los Angeles counties, California. A lectotype is designated for Stichopogon trifasciatus (Say), and Stichopogon salinus (Melander) from the eastern margin of the Great Basin is synonymized with S. trifasciatus (new synonymy). An identification key to the three Nearctic species of Stichopogon with white-banded abdomens is presented.

Terrestrial arthropods of Steel Creek, Buffalo National River, Arkansas. IV. Asilidae and other Diptera

Abstract Background This is the fourth in a series of papers detailing the terrestrial arthropods collected during an intensive survey of a site near Steel Creek campground along the Buffalo National River in Arkansas. The survey was conducted over a period of eight and a half months in 2013 using twelve trap types, including Malaise and canopy traps, Lindgren multifunnel traps, and pan traps. New information We provide collection records for 38 species of Asilidae and other Diptera, 7 of which are new state records for Arkansas: (Asilidae) Lasiopogon opaculus Loew, 1874; (Lygistorrhinidae) Lygistorrhina sancthecatharinae Thompson, 1975; (Stratiomyidae) Cephalochrysa nigricornis (Loew, 1866), Gowdeyana punctifera (Malloch, 1915), Sargus decorus Say, 1824; (Ulidiidae) Callopistromyia annulipes Macquart, 1855; and (Xylophagidae) Rachicerus obscuripennis Loew, 1863.

The Pupal Case of a Nearctic Robber Fly, Efferia snowi (Hine, 1919) (Diptera: Asilidae)

Abstract The pupal case of the Nearctic robber fly, Efferia snowi (Hine, 1919), is described, illustrated, and compared with the pupal cases of five other Nearctic species. A key is provided to the known pupal cases of Nearctic Efferia species.

The Pupal Case of a Nearctic Robber Fly, Proctacanthus brevipennis (Wiedemann, 1828) (Diptera: Asilidae)

Abstract. The pupal case of the Nearctic robber fly Proctacanthus brevipennis (Wiedemann, 1828) is described, illustrated, and compared with those of P. hinei Bromley, 1928; P. micans Schiner, 1867; P. milbertii Macquart, 1838; P. philadelphicus Macquart, 1838; and P. rufus Williston, 1885. A revised key is provided to the pupal cases of these species. Observations are reported on emerging adults and a newly emerged female P. brevipennis being captured and eaten by a green anole, Anolis carolinensis (Voigt, 1832).

The pupal case of a Nearctic robber fly, Diogmites contortus Bromley 1936 (Diptera: Asilidae)

Abstract The pupal case of the Nearctic robber fly, Diogmites contortus Bromley 1936, is described, illustrated, and compared with the pupal cases of three other Nearctic species, D. discolor Loew 1866, D. misellus (Loew 1866), and D. neoternatus (Bromley 1931). A key is provided to the pupal cases of these species. The main characteristics of the D. contortus pupal case are, (1) abdominal segment 1 with dorsal transverse row of 30 spurs, (2) abdominal segments 5–7 with uninterrupted ventral row of 41–47 bristle-like spines, and (3) abdominal segment 8 with 8 lateral bristle-like spines on each side.
