The bloodsucking biting midges of Argentina (Diptera: Ceratopogonidae)

A key is presented for the identification of the adults of 54 species of bloodsucking ceratopogonids, 51 of which are known inhabitants of Argentina, and Culicoides uruguayensis Ronderos, C. pifanoi Ortiz, and C. trilineatus Fox, which are known to occur in bordering Uruguay and Paraguay. Wing photographs are provided of females of the 45 species of Culicoides. Three new species of Culicoides Latreille from Northeastern Argentina are described and illustrated: C. austroparaensis Spinelli, C. bachmanni Spinelli, and C. williamsi Spinelli. The following six species are recorded for the first time from Argentina and/or bordering localities in Paraguay: Leptoconops brasiliensis (Lutz), C. gabaldoni Ortiz, C. ginesi Ortiz, C. pifanoi Ortiz, C. pseudocrescentis Tavares and Luna Dias, and C. trilineatus; and C. estevezae Ronderos and Spinelli is newly recorded from Misiones province of Argentina. C. lopesi Barretto is excluded from the Argentinean ceratopogonid fauna.

Description of Culicoides (Mataemyia) felippebauerae sp. n., Forcipomyia musae immatures, and occurrence of F. genualis, breeding in banana stems in Brazilian Amazonia (Diptera: Ceratopogonidae)

The following three species of Ceratopogonidae were collected breeding in the rhizomatous herb Phenakospermum guyannense Endl., 1833 in the vicinity of Manaus, Brazil, a new species, Culicoides (Mataemyia) felippebauerae Spinelli, Forcipomyia (Forcipomyia) genualis (Loew), and F. (Phytohelea) musae Clastrier & Dellécole. C. (M.) felippebauerae is described and illustrated as adult, pupa, and fourth instar larva, the adult compared with the adult of C. barthi Taveres and Souza and larva and pupa with those of C. dicrourus Wirth & Blanton and C. macieli Tavares & Ruiz, the only species with known immatures in the subgenus. The pupa and fourth instar larva of F. (P.) musae are described and illustrated and compared with immatures of F. (P.) edwardsi Saunders.

Redescription of the immatures stages of Forcipomyia (Phytohelea) bromelicola (Lutz, 1914) (Diptera: Ceratopogonidae)

The fourth instar larva and pupa of Forcipomyia (Phytohelea) bromelicola (Lutz) are redescribed and illustrated, and compared with immatures of F. (P.) musae Clastrier and Delécolle and F. (P.) dominicana de Meillon and Wirth. Both life stages were photographed using scanning electron microscopy and phase-contrast light microscopy. The immatures were collected from bromeliads in Florida, USA.

The Patagonian species of the genus Atrichopogon Kieffer, with a biogeographic analysis based on Forcipomyiinae (Diptera: Ceratopogonidae)

The following five new species of Atrichopogon Kieffer from southern Argentina and Chile are described and illustrated: A . aridus Spinelli & Marino, A . comechingon S. & M., A . endemicus S. & M., A . inacayali S. & M. and A. similis S. & M. A. aridus and A . comechingon also occur north of Patagonia. The previously known species A . obfuscatus Ingram & Macfie is redescribed, and notes on its type are provided. A key to recognition of males and females of the seven species inhabiting Patagonia is included. A biogeographic parsimony analysis of endemicity (PAE) interprets the relationships among the provinces of the southern South America. It is based on seven areas of endemism and distributional data of 30 species of the subfamily Forcipomyiinae. The analysis results in two most parsimonious cladograms and their strict consensus depicts the following relationships: ((Monte, Patagonian steppe) (Central Chile, Magellanic Moorland (Magellanic Forest, Maule, Valdivian Forest))).

A new species of Bezzia Kieffer from Argentinean Patagonia (Diptera: Ceratopogonidae)

Abstract. Bezzia, galesa Spinelli, a new Patagonian species, is described in all stages and illustrated by using binocular, phase-contrast and scanning electron microscopy. Immatures were collected associated to submerged filamentous algae in an unnamed pond in western Chubut province, Argentina, and reared to adults in the laboratory. Adults and immatures of this new species are compared with the most similar species Bezzia ventanensis Spinelli, Bezzia, roldani Spinelli et Wirth and Bezzia blantoni Spinelli et Wirth. Details on the rearing process and feeding behavior in laboratory are given.

A new Neotropical species of Atrichopogon Kieffer, and a redescription of A. casali Cavalieri & Chiossone (Diptera: Ceratopogonidae)

A new species of Atrichopogon with distinctively pigmented wings, A. clastrieri, is described and illustrated from males and females collected in several localities of northern Argentina and Paraguay, and compared with its most similar congeners A. bicuspis Borkent & Picado, A. nubeculosus Macfie and A. nebulosus Macfie. Male and female of A. casali Cavalieri & Chiossone were collected together in northeastern Argentina and Paraguay and are described and illustrated. The allotype of A. casali was misidentified in the original description and belongs to some other, possibly undescribed, species. Sobre la base de macho y hembra capturados en diferentes localidades del norte de Argentina y de Paraguay, se describe e ilustra una especie nueva de Atrichopogon con alas pigmentadas, A. clastrieri. Esta nueva especie es comparada con A. bicuspis Borkent & Picado, A. nubeculosus Macfie and A. nebulosus Macfie, sus congéneres con alas pigmentadas mas similares. Se describen e ilustran el macho y la hembra de A. casali Cavalieri & Chiossone, capturados en asociación en el noreste de Argentina y Paraguay. El alotipo de A. casali fue identificado erróneamente en la descripción original y pertenece a otra especie no identificada.

New contributions to the knowledge of the immatures of Stilobezzia punctulata Lane and Stilobezzia fiebrigi Kieffer (Diptera: Ceratopogonidae).

The fourth instar larva of Stilobezzia punctulata Lane is described for the first time and the one of Stilobezzia fiebrigi Kieffer is redescribed. They are illustrated and photomicrographed from material collected in different aquatic environments of the province of Corrientes, Argentina. Both species show features typical to carnivorous-predatory larva.

The following three new species of Forcipomyia ( Metaforcipomyia ) from southern Argentina and Chile are described and illustrated: F . mapuche and F . morenoi from northwestern Patagonia, and F . darwini from Deceit island in the Cape Horn. The previously known, spotted-wing species F . maculosa Ingram & Macfie is placed in the subgenus Metaforcipomyia , and notes on its type are provided. Forcipomyia galliarii Marino & Spinelli is excluded from the subgenus Metaforcipomyia and is considered to belong to the subgenus Euprojoannisia Brethes. A key to females and males of the seven New World species of the subgenus is included. Se describen e ilustran las siguientes tres especies nuevas de Forcipomyia ( Metaforcipomyia ) del sur de la Argentina y Chile: F . mapuche y F . morenoi del noroeste de la Patagonia, y F . darwini de la isla Deceit en el Cabo de Hornos. Se incluye en el subgenero Metaforcipomyia a F . maculosa Ingram & Macfie, y se ofrecen notas obtenidas a partir del estudio del tipo. Se excluye del subgenero Metaforcipomyia a Forcipomyia galliarii Marino & Spinelli, y es considerado como perteneciente al subgenero Euprojoannisia Brethes. Se incluye una clave para hembras y machos de las siete especies del subgenero que habitan el Nuevo Mundo.

A Revision of the Forcipomyia squamitibia Group in the Neotropics with the Description of Three New Species (Diptera: Ceratopogonidae)

A revision of the Neotropical species of the Forcipomyia squamitibia group, revealed three new species, F. (F.) catarinensis from southern Brazil, Colombia and Costa Rica, F. (F.) quechua from northwestern Argentina and F. (F.) rioplatensis from northeastern Argentina and northwestern Uruguay, which are described and illustrated. Forcipomyia (F.) squamitibia Lutz is redescribed from the original type material, a lectotype is designated, and F. (F.) soriai Wirth is recognised as a junior synonym. The remaining known species of this group are diagnosed, and keys to males and females are provided for the identification of the nine recognised species.RésuméTrois nouvelles espèces du groupe Forcipomyia squamitibia, F. (F.) catarinensis n. sp. du sud du Brésil, Colombie et Costa-Rica, F. (F.) quechua n. sp. du nord-ouest de l’Argentine et F. (F.) rioplatensis n. sp. du nord-est de l’Argentine et nord-ouest de l’Uruguay sont décrites et dessinées. On redécrit Forcipomyia (F.) squamitibia Lutz, avec le materiel type, on designe le lectotype et on propose F. (F.) soriai Wirth comme un nouveau synonyme de F. (F.) squamitibia. On diagnostique les autres espèces du groupe connues et on donne une clé pour identifier les mâles et les femelles des neuf espèces reconnues du groupe squamitibia.
