Comparative morphology of internal reproductive systems in leaf beetles of the Donaciinae and Criocerinae (Coleoptera: Chrysomelidae) and its implication for the phylogeny Author Matsumura, Yoko Author Suzuki, Kunio text Zootaxa 2008 1845 1 32 journal article 10.5281/zenodo.183289 fe86ae71-2d16-4bc9-a414-ab955d4399f3 1175-5326 183289 14. Lema ( Lema ) concinnipennis Aedeagus ( Figs. 78 , 94 & 95 ): Median lobe stubby; ventral edge of median orifice slightly rounded; median foramen shorter than apical 1/3 of ventral surface of median lobe. Tegmen forming needle-shaped in lateral view. Male internal reproductive system ( Fig. 106 ): Testis large, almost oval and constricted at middle (i.e. peanut-shaped), yellowish orange in color. Accessory gland tubular and slender, about 1/3 times as long as maximal width of apparent testis. Lateral ejaculatory duct a little over than 1/3 times as long as maximal width of apparent testis; common ejaculatory duct relatively short, tapering toward apex, about 2/3 times as long as maximal width of apparent testis. Female internal reproductive system ( Figs. 122 , 142–144 ): Spermathecal organ connected to bursa copulatrix apically. Spermathecal capsule hook-shaped, light yellowish brown in color; proximal part of spermathecal capsule tubular, gradually becoming bold toward base, curving very acutely at basal 1/3 point; spermathecal wall relatively thick; spermathecal duct long, 2/3–3/4 times as long as body length; spermathecal gland tubular, becoming bold toward apex, and about 1.5 times as long as maximal length of spermathecal capsule.
