Comparative aspects of the internal reproductive system of males in species of Melolonthinae, Dynastinae, and Rutelinae (Coleoptera: Scarabaeoidea) from Mexico
The anatomy of the internal male reproductive systems of 12 species of Melolonthinae (Phyllophaga, Chlaenobia, Macrodactylus, Isonychus), six species of Dynastinae (Cyclocephala), and three species of Rutelinae (Paranomala) (Coleoptera, Scarabaeoidea) of Mexico are described. A total of 350 male spe...

| description | The anatomy of the internal male reproductive systems of 12 species of Melolonthinae (Phyllophaga, Chlaenobia, Macrodactylus, Isonychus), six species of Dynastinae (Cyclocephala), and three species of Rutelinae (Paranomala) (Coleoptera, Scarabaeoidea) of Mexico are described. A total of 350 male specimens representing 21 species were collected. From each species, the reproductive systems were obtained by micro-dissection, placed in a liquid fixative, stained, and drawn to scale. The internal genitalia of each species was described and compared among the species examined. The reproductive system of the Melolonthinae species is comprised of two testicles, each with six follicles, two deferent ducts, two accessory glands, two glandular ducts, an ejaculatory duct, and the aedeagus (not described for any of the species examined). The number of testicular follicles per testicle is as reported in different species of other Scarabaeoidea subfamilies. The length of the accessory glands and the ejaculatory duct varies in the species studied. The ejaculatory bulb is present in all of the species of Dynastinae and Rutelinae examined but in only three species of Melolonthinae. |

Se describió la anatomía del sistema reproductivo interno de los machos en 12 especies de Melolonthinae (Phyllophaga, Chlaenobia, Macrodactylus, Isonychus), seis de Dynastinae (Cyclocephala) y tres de Rutelinae (Paranomala) (Coleoptera, Scarabaeoidea) de México. Se recolectaron un total de 350 ejemplares machos representantes de 21 especies. De cada especie se obtuvieron los sistemas reproductivos por microdisección y fueron colocados en un líquido fijador, después teñidos y dibujados a escala. Se describió la genitalia interna de cada especie y se comparó entre las especies examinadas. El sistema reproductivo de las especies de Melolonthinae consta de dos testículos cada uno con seis folículos, dos conductos deferentes, dos glándulas accesorias, dos conductos glandulares, un conducto eyaculador y el edeago (no descrito en ninguna especie). El número de folículos testiculares por testículo es igual al conocido en diferentes especies de otras subfamilias de Scarabaeoidea. La longitud de las glándulas accesorias y del conducto eyaculador varían dependiendo de cada especie estudiada. Un bulbo eyaculador está presente sólo en tres especies de Melolonthinae y en todas las especies de Dynastinae y Rutelinae examinadas.
