A new synonymy and a new species of Mydidae (Diptera) from Madagascar

摘要

Kondratieff al. (2005) proposed a new genus of mydas fly, Hessemydas from Madagascar and included two new species, H. parkeri Kondratieff, Carr and Irwin and H. tulear Kondratieff, Carr and Irwin. Additionally, the previously described Leptomydas seyrigi Seguy, the only mydas fly previously known from the island was placed in Hessemydas. Seguy (1960) originally described this species from a single male collected at Behara. Kondratieff al. (2005) indicated that despite numerous inquires to the MuseumNational d'Histoire Naturelle, Paris, France, the holotype of L. seyrigi was unavailable for examination. However, recently, through the courtesy of Christophe Daugeron, the holotype was located and made available for examination. Unfortunately, H. tulear was determined to be a junior subjective synonym of H. seyrigi. Also recently, Norman D. Penny, California Academy of Sciences made additional specimens of mydas flies available from Madagascar for determination. Among this material, a new species of Hessemydas was discovered and is described below.
