4. Donacia (Donaciomima) clavareaui

Aedeagus (Fig. 12): Median lobe slender, anterior half of median lobe slightly expanded; ventral edge of median orifice stretched widely and projecting at middle; median foramen expanding apical 1/4 of ventral surface of median lobe. Tegmen in ventrum forming triangular lobe in lateral view and in dorsum forming slen- der lobe in dorsal view.

Male internal reproductive system (Fig. 24): Testis discoid in shape, milky white in color. Accessory glands tubular, tapering toward base; of a pair of accessory glands, shorter gland about half length to and longer gland almost equal length to maximal width of 2 testis lobes combined. Lateral ejaculatory duct tapering toward base, a little less than 2/3 times as long as maximal width of 2 testis lobes combined; common ejaculatory duct about 4.5 times as long as maximal width of 2 testis lobes combined.

Female internal reproductive system (Figs. 41, 61 & 62): Egg cream-yellow in color. Spermathecal organ connected to bursa copulatrix ventro-apically. Spermathecal capsule hook-shaped, slightly tapering toward apex, pale yellowish brown in color and gradually deepening toward base; spermathecal wall relatively thick apically and proximally; spermathecal duct becoming bold toward base, almost equal length to maximal length of spermathecal capsule; spermathecal gland relatively long, about 5.5 times as long as maximal length of spermathecal capsule.
