Abstract

SPINELLI, Gustavo R.; MARINO, Pablo I.  and  MAUAD, Melina. Wing pattern variation in the Patagonian biting midge, Forcipomyia (Forcipomyia) multipicta Ingram & Macfe (Diptera, Ceratopogonidae). Rev. Soc. Entomol. Argent. [online]. 2012, vol.71, n.3-4, pp.309-313. ISSN 0373-5680.

Examination of the type-series and non-type specimens of the Patagonian biting midge, Forcipomyia (Forcipomyia) multipicta Ingram & Macfie (Diptera: Ceratopogonidae), revealed considerable variation in wing patterns of both sexes. One pattern includes several distinct light spot areas, whereas another pattern (e.g, in the holotype) only features marginal light spots in cell r₃, while other light spots are barely perceptible or absent. The cause(s) of the differential lack of dark macrotrichia in certain areas of the wing membrane in specimens of some series could not be attributed either to their age, sex, or method of preservation.

Keywords : Diptera; Ceratopogonidae; Biting midge; Forcipomyia multipicta; Intraspecific variation; Wing pattern; Patagonia.
