Tipula (Vestiplex) sternotuberculata Alexander, 1935 ( Fig. 7 )

Description. Bursa copulatrix straight and elongated, narrowed medially. Spermatheca three, pear-shaped, laterals (width 0.20 mm, length 0.30 mm) smaller than central one (width 0.25 mm, length 0.35 mm). Spermathecal ducts slightly narrower than bursa copulatrix, not arising from same level, lateral ducts distinctly longer than central one. Lateral ducts same length as bursa copulatrix, butcentral duct shorter, lateral ducts arising front of a single tube. Accessory gland being elongated sac, swollen, connected to each other by narrow tube, terminating in an elongated stem which broad basally and gradually narrowed to apex, subequal in length to accessory gland, connected to base of bursa copulatrix ( Fig. 7 ).

Remarks. In the two species of the subgenus Tipula (Vestiplex) , their accessory glands are sac-like and elongated. We also observed that the middle spermatheca is bigger than the lateral spermathecae in both species.
