CRUZ ROSALES, Magdalena  and  CASTILLO, María Luisa. Morfología del aparato reproductor en Odontotaenius striatopunctatus (Percheron, 1835) (Coleoptera: Passalidae). Acta Zool. Mex [online]. 2008, vol.24, n.2, pp.23-37. ISSN 2448-8445.

Female and male reproductive system anatomy of Odontotaenius striatopunctatus is described. This passalid species is common inside decomposition logs in the tropical forests of Mesoamerica. The female reproductive system consists of two ovaries with two ovarioles each, two lateral oviducts, a long oviduct, a genital chamber, a bursa copulatrix and a big spermatheca with its gland. The male reproductive system consists of two testes, each with a pair of testicular follicles and respective vas deferens, two seminal vesicles in each side, a long ductus eyaculatorius, the aedeagus, and two pairs of accessory glands. Two males were found with different numbers of testicular follicles. The spermatophore is described by first time for the family.
