First record of a Japanese marine shore dolichopodid fly, Thambemyia (= Conchopus) borealis (Takagi), from the Neotropical Region (Diptera: Dolichopodidae)
Abstract:Thambemyia Oldroyd is a marine shore dolichopodid genus in the aphrosyline subgroup of the subfamily Hydrophorinae. The genus was erected by Oldroyd (1956) based on the greatly elongated proboscis of the Malaysian species T. pagdeni Oldroyd. Since the early 1980’s the generic limits of Thambemyia have been in flux as a result of differing opinions regarding the proposed synonymy of the related genus Conchopus Takagi, 1965 by Meuffels & Grootaert (1984). Masunaga et al. (2005) argued to retain the generic s… Show more
“…The aphrosyline genus Thambemyia (as synonym of Conchopus) consists of 30 described species (Yang et al 2006;Masunaga & Saigusa 2010;Grichanov 2013) from China, Japan, Thailand, Malaysia, Brunei, Hawaiian Islands and India. Additionally, T. borealis (Takagi), 1965 is introduced in New World, with records from USA (Masunaga et al 1999) and Peru (Brooks & Cumming 2009). Species of Thambemyia are exclusive inhabitants of rocky seashores, and the life history of T. borealis was described by Sunose & Satô (1994).…”
A new species of Thambemyia Oldroyd, T. fusariae sp. nov., is described from the Brazilian State of Bahia. This is the first record of Thambemyia from the Neotropical Region, apart the Palearctic T. borealis (Takagi), introduced in USA and Peru. T. fusariae sp. nov. belongs to the subgenus Thambemyia, making the group an unusual case of Neotropical-Oriental disjunction.
