A preliminary phylogeny of Tipula and taxonomic placement of the subgenus Tipula (Sivatipula) (Diptera: Tipuloidea) based on mitochondrial COI gene

The large genus Tipula Linnaeus,1758 contributes heavily to the biodiversity of the family Tipulidae.However,the monophyly of Tipula has not yet been verified.The subgenus Sivatipula Alexander,1964 is possibly the most confusing subgeneric taxon in the genus Tipula because of its members’particularly long antenna and one-armed posterior immovable apodeme on semen pump,which makes its subgeneric position uncertain.In this research,the sequences of cytochrome oxidase I(COI)for 19 Tipula species and five taxa from other genera are analyzed.Considering the molecular evidence on genetic distance as well as phylogenetic analysis and morphological information,our results indicate that(1)the genus Tipula is not resolved as monophyletic in phylogeny based on neighbor joining(NJ)and maximum likelihood(ML)trees because the subgenus Sivatipula doesn’t form a monophyletic clade with the remaining subgenera of Tipula;and(2)Sivatipula may deserve a generic status since it forms an independent phylogenetic line.

Two new species in the subgenus Formotipula Matsumura(Diptera:Tipulidae:Tipula)from China

The morphological differences of internal reproductive organs for these species are listed. Additionally, the characteristic modes of internal reproductive systems for Tipulidae and Limoniidae are compared and summarized.

A new species of Brachypremna(Diptera:Tipulidae)from Dominican amber,with a key of the genus to all fossil species

A new species of Brachypremna Osten-Sacken, 1887 from Dominican amber is described and illustrated, namely B. chenhuameii sp. nov.. The new species is most similar to another fossil species documented in Dominican amber, B. brodzinskii Krzemiński, 1996, by the wing pattern, but is separated from the latter by the absence of final part of Sc, the arcuate origin of Rs, and the length of petiole of cell m1, which is distinctly longer than the cross vein m-m. A key to all fossil species of the genus Brachypremna is provided.
