          Abstract

          Se describe la anatomía e histología del aparato reproductor de hembras y machos de Odontotaenius striatopunctatus, especie de pasálido frecuente en bosques tropicales de Mesoamérica. El aparato reproductor de las hembras está constituido por un par de ovarios, cada uno con un par de ovariolas, dos oviductos laterales, un largo oviducto medio una cámara genital, una bursa copulatrix y una gran espermateca incluyendo su glándula. Los machos tienen un par de testículos, cada uno con un par de folículos testiculares, sus conductos deferentes, una vesícula seminal por cada lado, un conducto eyaculador y dos pares de glándulas accesorias. Se menciona la incidencia en los machos de variaciones en el número de folículos testiculares, y se pone en evidencia la presencia de espermatóforo en la familia Passalidae.

          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.
