Internal sclerite present, heavily sclerotized, except in <i>Di. leukommatos</i> <b>sp. nov.</b> and <i>Di. trimaculatus</i> <b>sp. nov.</b>, positioned next to basal pouch (Figs. 4; 5; 10; 13; 16; 19; 22; 25 and 50H). Ventral lobe with several small digitiform projections; posteriorly with subdivided flagellum in lower and upper lobules. <i>Female</i>. Similar to male, but differing in following aspects: body more robust, longer and wider. Anterior femur as long as wide (Fig. 6A). Abdomen narrowing from abdominal segment 7 towards apex (Fig. 6B-C). Subgenital plate elongated, ellipsoid or rectangular, reaching tergum 10 (Fig. 6D). <i>Examined female material</i>.

Females could not be associated with males due to three reasons: 1) all of the <i>Dinelytron</i> species analyzed were mainly distinguished by the male terminalia and genitalia; 2) diagnostic external morphological characters of the males (e.g. shape of the labrum and clypeus) were not found in the females, even when both sexes were collected in the same area; 3) in some cases, more than one female species were collected at the same location (e.g. Rio de Janeiro, Itatiaia). A safer association can only be achieved through rearing from eggs and molecular analyses. <i>Species included</i>: <i>Dinelytron agrion</i> (<b>note</b>: although it is below demonstrated that it does not belong to <i>Dinelytron</i>, it is not going to be transferred to another genus in the present work). <i>Dinelytron betinho</i> <b>sp. nov.</b> <i>Dinelytron grylloides</i> type-species. <i>Dinelytron hipponax</i> incertae sedis. <i>Dinelytron leukommatos</i> <b>sp. nov.</b> <i>Dinelytron museunacional</i> <b>sp. nov.</b> <i>Dinelytron ramusculus</i> <b>sp. nov.</b> <i>D. shuckardi</i> incertae sedis. <i>Dinelytron trimaculatus</i> <b>sp. nov.</b> <i>Dinelytron unilineatus</i> <b>comb. nov.</b>
