description: <i>Dinelytron agrion</i> Westwood, 1859. <i>Dinelytron agrion</i> Westwood, 1859: 6; Kirby 1904: 408 (commentaries on holotype); Redtenbacher 1906: 150 (redescription); Rafael &amp; Heleodoro, 2017 (Brazilian catalog); Brock et al. 2019 (world catalog). <i>Examined material</i>. Holotype <i>_</i> (Fig. 4A) (examined by photo): “BM [British Museum], agrion, westw. [ood], Vila Nova [Amazonas, Tapajos river], Bates [collector], <i>Dinelytron</i> ? Agrion, Westw., Amazon, Villa Nova ” (NHM). Ordinary material: “ Brasil, Manaus, Res. Ducke, 01.xii.2013, E. Aluim col.” (1 <i>_</i> INPA). <i>Description of genitalia</i> (<i>_</i>). Mainly membranous, with dorsal and ventral lobe continuously connected. Dorsal lobe having small rigid spiny sensilla; left, median and right posterior processes conspicuously present; with conspicuous sclerotization, heavily pigmented at left median margin (Fig. 7A, C, E) Median posterior process with several small spikes (Fig. 7E). Dorsal left sclerite slender, tubuliform, slightly curved; completely internal and close to dorsal-most wall of the genitalia; cleft between ducts conspicuous (Fig. 7A). Basal pouch bifurcated, resembling a “U”, pointed latero-posteriorly, external to genitalia (Fig. 7A, B). Sclerotized tube of ejaculatory duct present, with triangular base, positioned next to dorsal left sclerite, seeming connected (Fig. 7C). Internal sclerite present, “C” shaped, positioned under basal pouch (Fig. 7D). Ventral lobe with lower and upper lobule, having several small scattered sensilla. Having small bifurcated digitiform projection medially at upper lobule. <i>Holotype condition</i>. Mid left and right posterior legs missing. Right posterior wing basally broken in anal area. <i>Geographical records</i>. Brazil, <i>Amazonas</i>: Manaus. <i>Remarks</i>. Westwood (1859) described this species uncertain of its placement in <i>Dinelytron</i>. Kirby (1904) had the same doubt when examining the holotype, but confirmed that <i>D. agrion</i> was related to Prisopodidae. As our results demonstrate, this species belongs without a doubt to Paraprisopodini, due to the short tegmina and convex venter. Furthermore, the male genitalia do not fit in the pattern of any Prisopodini genus. Despite all these evidences, this species <b>is not going to</b> be transferred to another tribe or genus in the present work to respect the unpublished work of Oskar Conle (pers. comm., unpublished results), whom reached this conclusion previously. Thus, in the present work, <i>Di. agrion</i> is still treated as <i>Dinelytron</i> and to highlight this decision the name of the species is displayed between quotation marks in the phylogeny results. This is the first time the genitalia of this species are described.
