Calopterygoidea Selys-Longchamps 1850

Description

4.1.5.1. ‘ Calopterygoidea ’ group 1 - Priscagrionidae .

This group includes only the newly established family Priscagrionidae (see below Revisions to the Classification of Zygoptera), which was represented by a single taxon in our analysis: Priscagrion kiautai. Previously placed tentatively in the superfamily Calopterygoidea, it is now recovered as sister to the remaining ‘Calopterygoidea’ + Coenagrionoidea (BS = 100, PP = 1, QS = 0.92/0/0.99). In the molecular analyses of Dijkstra et al. (2014), Priscagrion was found to group with Sinocnemis and previously called Incertae Sedis Group 5 (Dijkstra et al., 2014; Schorr and Paulson, 2019). Therefore we propose the family, Priscagrionidae (see below Revisions to the Classification of Zygoptera), which includes two genera, Priscagrion and Sinocnemis, with two and three species respectively. The genera are restricted to streams in China and Vietnam, are similar in build and coloration with relatively long legs, and share the apparent apomorphy of a drawn-out internal fold on the genital ligula. Remarkably, both genera were described only in the past two decades and little has been published on their behaviour. Both perch with wings open, with Sinocnemis resting on broad leaves (Kalkman, 2008) and pictures in (Zhang, 2019). No nymphs are known for either genus.
