3893: a distal + mesial fragment of a quadrangular-section sagaie, 10 mm wide x 10 mm thick with both perpendicular and zigzag or 'tectiform' marks on one face and many short tick marks along two edges (Fig.
Macropterous, wings broad and elongate, well exceeding abdomen, held steeply tectiform (almost parallel to body) in repose.
Males are characterised by the tectiform anal segment and strongly reduced vomer, which is almost fully covered by the poculum.
IX considerably shorter than VIII and tectiform; both with the posterior margin irregularly sinuate and tuberculate.
IX considerably shorter than VIII, narrowed towards the posterior, tectiform and with a very blunt longitudinal median bulge, which diverges in the posterior half and terminates in two low, rounded lobes near posterior margin of segment.
IX about half the length of VIII and slightly tectiform. Anal segment strongly declivent with the posterior margin narrowed and produced in two small rounded projections on each side of the base of the supra-anal plate, the latter tectiform, shorter than anal segment and gradually narrowed towards a bluntly rounded apex.
Calcar approximately 2/3 length of basitarsus (0.69:1, n = 11), flattened, tectiform, and narrowing distally to acuminate apex, bearing a continuous row of 18 or more black-tipped teeth on outer lateral margin (range 18-23; n = 11; 20 on holotype).
Calcar approximately 2/3 length of basitarsus (0.71:1), flattened, tectiform, and narrowing distally to acuminate apex, bearing a continuous row of more than 15 black-tipped teeth on outer lateral margin (range 16-25; 18 on holotype).
Calcar slightly shorter in length than basitarsus (0.9:1), calcar flattened, tectiform, and narrowing distally to acuminate apex, bearing a continuous row of more than 15 very small black-tipped teeth on posterolateral margin (15-18) becoming reduced near apex.
