To include the new taxon in the key to Mexican and Central American species of Lestes in MAY (1993), the following modifications should be done:

6(5’) Paraprocts long (more than 0.90 length ofcerci), extending well beyond posterior limit of medial dilatation of cerci........................................................................................................... ....................................... 7

6’ Paraprocts shorter (barely more than 0.70 length of cerci) extending little beyond posterior limit of medial dilatation of cerci.................................................................................................................................. 8

7(6) Mesepisterna with a narrow, metallic green stripe, not contiguous with middorsal carina. Medial dilatation of cerci well developed and strongly serrated.......................................................................... forficula

T Mesepistema with a wide, dark stripe, contiguous with middorsal carina. Medial dilatation of cerci angulated and very slightly denticulated.................................................................................. alfonsoi

8 Cerci in dorsal view with medial dilatation consisting of a welldeveloped lobe ending posteriorly in a distinct notch, paraprocts not distinctly curved inward................................................................ alacer

S' Cerci in dorsal view with medial dilatation less prominent, not ending posteriorly in a distinct notch: paraprocts distinctly curved or slanted inward........................................................................... simplex *. o
