The final instar larvae of Argia reclusa Selys, 1865 and Tigriagrion aurantinigrum Calvert, 1909 are described, diagnosed and illustrated. The larvae of A. reclusa has a very prominent premental ligula, shared with a single species in Brazil, from which it can be separated by a combination of characters. The larvae of T. aurantinigrum is similar to most Oxyagrion in regard to prementum and lamellae shape, and differs from those taxa in palpal and premental setation and number of teeth on the labial palp. Both larvae were collected in a small stream of the Cerrado biome, where both species are common.
描述、诊断并图示了 Argia reclusa Selys, 1865 和 Tigriagrion aurantinigrum Calvert, 1909 的末龄幼虫。A. reclusa 的幼虫具有非常突出的前颏 Ligula，与巴西的一个单一物种共有，可通过组合特征将其与后者区分开来。T. aurantinigrum 的幼虫在颏部和 Lamellae 形状方面与大多数 Oxyagrion 相似，而在触角和前颏的毛和唇须上的齿数方面与这些分类群不同。这两种幼虫均在赛拉多生物群的小溪中采集，这两种物种在那里很常见。
