About Pseudagrion citricola Barnard, 1937
The mature male of Pseudagrion citricola has a bright yellow face, and a black head top with bright blue postocular spots. Its upper eyes are black, while the lower parts are yellow, amber, and light green. The upper thorax is dark blue, shiny when young, and becomes lightly pruinescent with age; the lower thorax is greenish blue. The abdomen is dull dark blue, and becomes more pruinescent in older specimens; the upper half of abdominal segments 8 and 9 is bright mauve-blue. The wings are clear, with dull brown pterostigmata that darken as the individual ages. In South Africa, only two other sprite species share the yellow face trait of Pseudagrion citricola. Pseudagrion gamblesi is much larger, has a striped thorax, and is restricted to faster-flowing rivers at lower altitudes in KwaZulu-Natal and Mpumalanga. Pseudagrion citricola occurs across the entire range of Pseudagrion caffrum, but Pseudagrion caffrum lacks blue postocular spots and has brighter rusty red pterostigmata. This sprite species is endemic to South Africa and Lesotho. It is most common in highland grasslands, but also occurs in the Karoo and at low elevations in parts of the Western and Eastern Cape. No known threats currently affect this species, and its population is locally abundant and apparently stable. Pseudagrion citricola inhabits pools and slow-flowing sections of streams and rivers.
