			'''Résumé''' (traduction libre)<br>
			Dans cette étude, les organes génitaux secondaires mâles de ''[[Platycnemis dealbata]]'' Selys dans Selys & Hagen, 1850 ont été examinés pour la première fois à l'aide d'un microscope électronique à balayage (MEB). La recherche a révélé les caractéristiques ultrastructurales et diverses structures sensorielles de ces organes. Deux types principaux de sensilles ont été identifiés dans l'organe génital secondaire : des sensilles chimiques présumées et des sensilles ciliées qui détectent les stimuli mécaniques. L'étude a examiné en détail des structures telles que la tête de la ligule, les hamuli antérieurs et postérieurs, la lame antérieure et les lames batilliformes. Quatre projections ont été observées sur la tête de la ligule, et il a été suggéré que ces projections jouent un rôle dans le transport du sperme. De plus, les sensilles ciliées sur le sternum aident à détecter le contact avec la femelle et à l'ancrage pendant l'accouplement. Cette recherche a comparé la structure génitale de ''P. dealbata'' avec d'autres espèces de ''[[Platycnemis]]'' et a révélé certaines similitudes et différences. L'étude contribue à notre connaissance de la biologie reproductive et de l'évolution.

	In this study, the secondary male genitalia of ''[[Platycnemis dealbata]]'' Selys ''in'' Selys & Hagen, 1850 was examined for the first time using Scanning Electron Microscope (SEM). The research revealed the ultrastructural features and various sensory structures of these organs. Two main types of sensilla were identified in the secondary genital organ: putative chemical sensilla and hair sensilla that detect mechanical stimuli. The study examined structures such as the ligula head, anterior and posterior hamuli, lamina anterior, and lamina batilliformes in detail. Four projections were observed on the ligula head, and it has been suggested that these projections play a role in sperm transport. Additionally, the hair sensilla on the sternum assist in detecting contact with the female and in anchoring during mating. This research compared the genital structure of ''P. dealbata'' with other ''[[Platycnemis]]'' species and revealed some similarities and differences. The study contributes to our knowledge of the reproductive biology and evolutionary adaptations of the [[Odonata]] taxon by presenting new hypotheses about the functions of these complex structures.
