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.
