GENUS MATRONA SELYS, 1853

de Selys Longchamps, 1853: 17. – Matrona , defined as subgenus of Calopteryx Leach [1815] . Type species: Matrona basilaris Selys, 1853 , as the only species.

Kirby, 1890: 100. – Matrona upgraded to genus.

Generic diagnosis: Rather large demoiselle damselflies with brilliant metallic green, slender body and long broad wings with rounded apices; male wings either wholly dark opaque or pale to medium brownish, lacking pterostigma; female wings brownish with creamy white pseudopterostigmata. Median space with partly reticulated cross-veins, a morphological synapomorphy that separates the genus both from Calopteryx Leach, 1815 and Atrocalopteryx Dumont et al., 2005 . Vein IA bifurcated, producing a branch basally. After diverging from RP3 (R4+5) the vein IR2 runs parallel to RA. Nodus situated nearer the base of wing than the apex. Wings with numerous intercalated veins. Legs long with slightly curved middle and hind tibiae.
