New taxa of Tanyderidae (Diptera) from Eocene Baltic amber

Abstract

Macrochile hornei sp. nov. from Baltic amber (Upper Eocene) is described and illustrated. Podemacrochile gen. nov. is described with Podemacrochile baltica (Podenas, 1997) as type species. A key to the genera and species of Tanyderidae known from Baltic amber is presented.

A new genus of Tanyderidae (Insecta: Diptera) from Myanmar amber, Upper Cretaceous

“…They have body size ranging from 6 to 30 mm in length (Judd, 2004), and relatively broad wings with prominent brown stripes or bands. The highest number of extant Tanyderidae species occur in the Australian Region (Krzemi nski et al, 2013b). The immature stages of the extant species are aquatic to semiaquatic including association with wet sandy soil and the outer layers of submerged rotting logs in streams.…”

“…The family might have been more diverse in species richness during the Mesozoic (Krzemi nski et al, 2013b). The fossil tanyderids comprise twenty two fossil and amber species in six genera (Bode, 1953;Kalugina, 1988;Kalugina, 1992;Krzemi nski and Ren, 2001;Ansorge and Krzemi nski, 2002;Zhang, 2004;Skibi nska and Krzemi nski, 2013;Krzemi nski et al, 2013b).…”

“…The fossil tanyderids comprise twenty two fossil and amber species in six genera (Bode, 1953;Kalugina, 1988;Kalugina, 1992;Krzemi nski and Ren, 2001;Ansorge and Krzemi nski, 2002;Zhang, 2004;Skibi nska and Krzemi nski, 2013;Krzemi nski et al, 2013b). They are Macrochile Loew, 1850(Upper Eocene), Protanyderus Handlirsch, 1909, Praemacrochile Kalugina, 1985 (from Lower Jurassic to Upper Jurassic), Nannotanyderus Ansorge, 1994 (from Lower Jurassic to Lower Cretaceous), Dacochile Poinar & Brown, 2004 (Cretaceous) and Podemacrochile Krzemi nski, Krzemi nska, Kania & Andrew, 2013 (upper Eocene).…”

“…But Krzemi nski et al suggested that it belongs to a new genus of Podemacrochile that is more similar to Praemacrochile or Nannotanyderus due to the wing venation and morphology of the hypopygium (Krzemi nski et al, 2013b). In addition, Krzemi nski et al described the second species of Macrochile (Macrochile hornei) from Baltic amber (Krzemi nski et al, 2013b). Nannotanyderus is unique for its small size with wing lengths ranging from 1.6 to 4.0 mm.…”
