Redescription of male and female genitalia of Tipula(Emodotipula) holoteles(Diptera), with notes on the structure of the semen pump in the subgenus Emodotipula

The original description of male hypopygium of Tipula(Emodotipula) holoteles Alexander, 1924 is expanded with additional morphological characters and detailed illustrations. The additional morphological descriptions of the female ovipositor along with detailed drawings are provided. The male semen pump and the female vaginal apodeme as well as the spermatheca are also described and illustrated for the first time, representing the first report of these structures of Tipula(Emodotipula) holoteles. Additionally, the taxonomic potential of the semen pump in the subgenus Emodotipula is analyzed and discussed. The new specific name Tipula(Emodotipula) yangi nom. nov. is proposed as a replacement name for junior homonym Tipula(Emodotipula) alexanderi Men, 2017. A worldwide checklist and a key to Chinese species of the subgenus Emodotipula are provided.

Comparative morphological study of female internal reproductive system among nine species in the genus Tipula(Diptera: Tipulidae)

Female internal reproductive systems of nine species in the genus Tipula are described and illustrated,namely T.(Beringotipula)amurensis Alexander,1925,T.(Lunatipula)lunata Linnaeus,1758,T.(Lunatipula)submanca Savchenko,1964,T.(Pterelachisus)biaciculifera Alexander,1937,T.(Sivatipula)parvauricula Alexander,1941,T.(Vestiplex)longitudinalis Nielsen,1929,T.(Vestiplex)sternotuberculata Alexander,1935,T.(Yamatotipula)couckei Tonnoir,1921 and T.(Yamatotipula)marginella Theowald,1980.The morphological differences of internal reproductive organs for these species are listed.Additionally,taxonomic potential of some internal reproductive structures are analyzed and discussed.
