1. Donacia (Cyphogaster) lenzi

Aedeagus ( Fig. 9 View FIGURES 9 – 20 ): Median lobe stubby, anterior half of median lobe slightly expanded; ventral edge of median orifice rounded and projecting at middle; median foramen shorter than half of ventral surface of median lobe. Tegmen in ventrum forming large triangular lobe in lateral view and in dorsum forming spoonshaped lobe in dorsal view.

Male internal reproductive system ( Fig. 21 View FIGURES 21 – 33 ): Testis discoidal in shape, milky white in color. Accessory glands very small relative to testis and sac-like; of a pair of accessory glands, both 1/4–1/3 times as long as maximal width of 2 testis lobes combined. Lateral ejaculatory duct uniform in width, 1/3–1/2 times as long as maximal width of 2 testis lobes combined; common ejaculatory duct 1.5–2.5 times as long as maximal width of 2 testis lobes combined.

Female internal reproductive system ( Figs. 34, 35 View FIGURES 34 – 57 & 58 View FIGURES 58 – 75 ): Spermathecal organ connected to bursa copulatrix dorso-apically. Spermathecal capsule scythe-shaped, constricted basally, its opening to spermathecal duct projecting dorsally, light yellowish brown in color; spermathecal duct uniform in width, 1/2–2/3 times as long as maximal length of spermathecal capsule; spermathecal gland tubular, relatively long, about 5 times as long as maximal length of spermathecal capsule.

A: Type of the proximal part of spermathecal capsule; B: presence or absence of the soft plate of the basal extremity of spermathecal duct.
