27. Oulema oryzae

Aedeagus (Fig. 91): Median lobe slender; ventral edge of median orifice projecting with rounded apex; median foramen shorter than apical 1/3 of ventral surface of median lobe. Tegmen forming boomerangshaped in lateral view and curved dorsally.

Male internal reproductive system (Fig. 118): Testis large, almost oval and strongly constricted at middle, yellowish orange in color. Accessory glands tubular; of a pair of accessory glands, shorter gland about half length to and longer gland 3/4 times as long as maximal width of apparent testis. Lateral ejaculatory duct relatively short, about 1/3 times as long as maximal width of apparent testis; common ejaculatory duct tapering toward apex, almost equal length to maximal width of apparent testis.

Female internal reproductive system (Figs. 138 & 162): Spermathecal organ connected to bursa copulatrix apically. Spermathecal capsule hook-shaped, tapering toward apex; proximal part of spermathecal capsule very complex, irregularly and highly twisted, uniform in width except proximal part expanded; spermathecal duct about 1.6–2.3 times as long as maximal length of distal part of spermathecal capsule; spermathecal gland tubular, becoming bold toward apex, 2.6–2.8 times as long as maximal length of distal part of spermathecal capsule.
