In the present study, the histoanatomy of the male reproductive organs was described for Pimelia subglobosa (Pallas, 1781) using light and scanning electron microscopy. Our study results revealed that the reproductive system in P. subglobosa consists of a pair of testes, vasa deferentia, seminal vesicles, two pairs of accessory glands (the first pair of glands is spiral shape and the second pair of glands is long-tubular shape), a ductus ejaculatorius and an aedeagus, all of which are described and illustrated. Each testis is made up of numerous oval testicular follicles. The testes resemble immature broccoli florets. The histo-anatomical examinations of testicular follicles showed that the growth, maturation and differentian zones contain various stages of spermatogenesis-spermiogenesis and could be divided into four stages depending on the shape and histological organization, which is divided into spermatogonia, spermatocytes, spermatids and spermatozoa. Sperm cells that are fully developed are transferred from testicular follicles to the vas deferens, which is in the form of a thin, long and convoluted duct. The seminal vesicle is a wide and sac-shaped structure into which the vas deferens enters. The first pair of accessory glands attach dorsally to the ejaculatory duct above the seminal vesicles. The wall of the second pair of accessory glands is very thin and located just above the first accessory gland. The ductus ejaculatorius connects the other parts of reproductive organs to the aedeagus. The aim of this paper is to summarize current state of knowledge of the male reproductive organs in P. subglobosa. These data are discussed in comparison with the male reproductive system in other coleopteran species.
