Malgassophlebia andzaba Dijkstra & Mézière, 2015
Redwater Leaftipper

Type locality: Batéké Plateau, Eaux Claires, Gabon

Diagnosis

Male is nearest sympatric M. westfalli by (a) the dark brown to black rather than yellow pronotal hindlobe; (b) the triangular rather than quadrangular Fw discoidal cell, i.e. the sector of the arculus joins it at its distal corner rather than about halfway along the anterior vein; (c) at least partly two rows of cells in the Fw discoidal field proximal to the node, rather than entirely one row from base to beyond node; (d) 6-10 cells in the anal loop, rather than only 3-4; (e) the gradually curved rather than abruptly subapically bent hamule; and (f) the terminally expanded and truncated cerci in lateral view. However, has (1) slightly smaller size, Hw 25.0-26.0 mm (n = 3) rather than 27.0-29.0 mm (n = 5); (2) the black on the labium not expanded laterally of the central lobe; (3) a pale brown rather than black occipital triangle, base of vertex and base of frons; (4) 6-7 cells in the anal loop, not 9-10; (5) the apical border of the genital lobe pointed and smooth, instead of broadly rounded bearing 3-6 denticles; (6) the dorsal carina of S4-8 yellowish brown rather than black; (7) the abdomen barely expanded and widest on S7, with S8 longer than wide, instead of distinctly clubbed and widest on S8, which is wider than long; (8) the cerci lacking a small ventral process at mid-length, well-separated rather than closely apposed in middle, truncated rather than pointed in dorsal view, and bearing an internal spine at their apex; and (9) a narrower epiproct whose base is eclipsed by the cerci in dorsal view and whose apical cleft and tips are triangular rather than rounded.
