Platycypha cf. caligata (Selys, 1853)
- scientific: P. caligata (Selys, 1853) f. â€ślacusâ€ť Pinhey, 1982
Type locality: Lake Malawi, Malawi
This form confined to Lake Malawi is potentially a distinct species. Male is similar to typical P. caligata by (a) humeral and metapleural stripes narrow, about as wide as hind femur is thick, black of mesepimeron usually clearly dissected by pale ‘posthumeral’ stripe; (b) sides of S1-3 and thorax reddish; (c) Abd at least blue on S6-10; (d) at most S2-5 with apical black bar; (e) paraprocts less than half as long as cerci (lateral view). However differs by (1) only on rocky shores of Lake Malawi; (2) smaller, Hw 18-19 mm rather than 20-24 mm; (3) tibiae narrow, outer dilation of hind tibia 1-2x as wide as shaft, rather than 2-4x; (4) with age, dorsal blue markings on S2-3 become rufous and S4-5 become largely black, rather than S2-5 all remaining blue.

Large lakes in open landscapes. Often splash zones, usually with rocks, and probably submerged roots, dead trunks or branches and/or coarse detritus. Recorded at around 400 m above sea level.
