| Abstract Acanthagrion marinae sp. nov. (Holotype male: BRASIL, Mato Grosso do Sul, Campo Grande, UFMS, 20°29’56.26’’S - 54°36’48.43’’W, 547m, leg. M.E. Rodrigues, 03.ii.2015, collection code: VZYG437, MLP) is described and illustrated on the basis of 15 males. The new species belongs to the apicale species group by having horns on S10 and sclerotized hooks on tip of distal segment of the genital ligula. It can be easily distinguished from other species of the group by a combination of characters of the genital ligulae (presence of setae on segment two; absence of setae at flexure; distal lateral lobes of segment three absent). Notes on habitat and a modification of previous keys for the species of the apicale group are provided. |

| Abstract The American genus Argia, with more than 100 species described, is the most speciose genus of Odonata in the world. In this contribution, the final stadium larva of Argia serva, the southernmost distributed species of Argia, is described and diagnosed based on reared material from Martín García island, Buenos Aires, Argentina. The larva of this species can be easily separated from the other Argentinean Argia by the following combination of characters: sternum of S8 covered with spines (bare in A. translata); antennal segment 3 longer than 1+2 (equal to or shorter than 1+2 in A. joergenseni and A. jujuya); palpal setae absent (present in A. croceipennis). A key to the known larvae of Argia of the Southern Cone is provided. |

| Argentagrion Fraser, currently considered a synonym of Homeoura Kennedy, is revalidated; both genera are rediagnosed and their species illustrated, keyed and mapped. Ischnura sobrina Schmidt is transferred to Homeoura, and a new species, H. obrieni is described, resulting in five species being included in Homeoura (H. chelifera (Selys), H. lindneri (Ris), H. nepos (Selys), H. obrieni sp. nov. and H. sobrina (Schmidt) comb. nov.) and two in Argentagrion (A. ambiguum (Ris) and A. silviae Bulla). |
