A revision of the Patagonian predaceous midges of the genus Palpomyia Meigen (Diptera: Ceratopogonidae).

This revision of the predaceous midges in the genus Palpomyia Meigen inhabiting the Patagonian region of Argentina and Chile recognizes eight species, provides diagnoses, descriptions, illustrations and a key to all species, as well as new distributional records of previously described species. Four new species are described and illustrated: P . mapuche , P . marinoi , P . septentrionalis and P . yamana (spp. n.). Palpomyia patagonica Ingram and Macfie and P . subfuscula I. and M. are redescribed and illustrated, the previously unknown male of P . patagonica is described and illustrated, and P . subaspera (Coquillett) is recorded for the first time from Patagonia. Palpomyia chilensis Ingram & Macfie is transferred to Austrosphaeromias Spinelli (n. comb.).

Biting midges of the genus Culicoides in South Carolina zoos

Abstract Biting midges of the genus Culicoides (Diptera: Ceratopogonidae) were collected during the summer of 2007 at the Greenville and Riverbanks Zoos in South Carolina with Centers for Disease Control and Prevention (CDC) traps equipped with ultraviolet or incandescent lights and baited with carbon dioxide. Sixteen species of Culicoides were collected, four of which represented more than 80%. They were Culicoides guttipennis (Coquillett), Culicoides mulrenanni Beck, Culicoides obsoletus (Meigen), and Culicoides sanguisuga (Coquillett). C. guttipennis was found on a dead colobus monkey and a dead golden-headed lion tamarin; Culicoides husseyi Wirth & Blanton was collected from an unidentified, abandoned birds nest. Ultraviolet light-equipped traps captured significantly more Culicoides specimens than traps with incandescent light. Half of the collected species previously have been associated with vertebrate pathogens, indicating a potential risk to captive animals.

The Old World biting midge, Forcipomyia (Lepidohelea) pulcherrima SANTOS ABREU, new to the fauna of the United States (Diptera: Ceratopogonidae)

ABSTRACT We provide the first United States records of the Old World biting midge, Forcipomyia (Lepidohelea) pulcherrima SANTOS ABREU (Diptera: Ceratopogonidae), from California, Florida and Hawaii. The fourth instar larva of F. pulcherrima is also described and illustrated for the first time.

A New Predaceous Midge in Brachypogon (Brachypogon) from Alabama and Florida, U.S.A. and New Distibution Records for Brachypogon woodruffi Spinelli and Grogan (Diptera: Ceratopogonidae)

Abstract. Brachypogon (Brachypogon) laneae Swanson and Grogan, new species is described from the Mobile—Tensaw Delta of Alabama, and additional collection localities are provided from Florida. A second species of Brachypogon (Brachypogon) Kieffer from Florida is described, but not named, based on a single male and a tentatively associated female. Brachypogon (Brachypogon) woodruffi Spinelli and Grogan is reported for the first time from Florida and the Cayman Islands, and the male terminalia are re-illustrated to depict certain diagnostic features. An identification key is provided for males and females of the subgenus Brachypogon in North America north of Mexico.

Two new species of the predaceous midge genus Amerohelea Grogan and Wirth from Argentina (Diptera: Ceratopogonidae)

Abstract. Two new species of the predaceous midge genus Amerohelea Grogan and Wirth are described and illustrated from Argentina: Amerohelea paranaensis, Gaddi, Spinelli and Grogan, new species, from the subtropical forest zone of Misiones Province, and Amerohelea xerophila, Gaddi, Spinelli and Grogan, new species, from arid regions in San Luis, Córdoba and Río Negro provinces. The male of A. paranaensis exhibits a tuft of stout setae on the ventral surface of tarsomere 1 of the foreleg, a character previously unknown in the genus. A key is provided for males and females of all species of Amerohelea.
