Does this fit?
Face: light blue and black. Labrum light blue with fine black base. Anteclypeus dirty light blue. Postclypeus black. Frons and genae light blue. Head above with black transverse band. A blue line runs across occiput but usually does not quite reach eyes. Sometimes this line is broken, forming postocular spots.
Eyes: light blue with black cap. Cap coincides with black head band.
Prothorax: black, with fine, broken light blue margins.
Synthorax: black and light blue stripes. Sometimes the blue is very light and brownish, and even occasionally completely brown.
Wings: clear.
Pterostigmas: dark grey, almost black, with fine pale margins.
Abdomen: light blue with a black dorsal line of varying widths, that ends in a taper at end of S7 (a little before in some WCP individuals). S8-9 above all blue. S10 blue with fine black stripe above. Superior appendages blackish with whitish extremity. Spine on inferior appendages mostly blue.
Female: with similar markings as male but light brown instead of blue.
Similar species:
This small, sky blue
Africallagma can vary from pale to bright sky, but not sapphire like
Af. sapphirinum.
Af. glaucum without a black marking on S8, unlike
Azuragrion nigridorsum, but like
Proischnura rotundipennis with which it can co-occur.
P. rotundipennis has S7 with black ending squarely at end of segment, not tapering like
Af. glaucum. Also, in life,
P. rotundipennis has blue on its pterostigmas, unlike
Af. glaucum. S9 is all blue in
Af. glaucum but blue and black in
Az. nigridorsum. S10 is much blacker in
Af. sapphirinum than in
Af. glaucum.
Af. elongatum, although with similar colour and patterning to
Af. glaucum, is distinctly more slender and has long black inferior appendages.
so very happy that I was close
