Genus Neoraistrickia (Potonie 1956).
Diagnosis: Trilete. Amb triangular. Sculpture varies in shape from spinate to
bacculate to pilate.
Known distribution: Permian of Western Australia (Balme and Hennelly 1956),
Permian of Tanganyika (Hart 1960), Upper Permian of Raniganj Coal (Bharadwaj
1962; Salujha 1964), Permian of Brazil (Cazzulo-Klepzig et al. 2009); Permian
of India (Mishra and Jha 2017).
Discussion: Neoraistrickia is distinguished from Raistrickia (Potonie and Kremp
1955) in outline; Raistrickia being circular in outline, while Neoraistrickia is distinguished by a triangular Amb. Horriditriletes (Bharadwaj and Salujha 1967)
closely resembles Neoraistrickia ramosa, and may well be its synonym. (Neoraistrickia) Horriditriletes ramosus is recorded from Lower Permian of Godavari
Graben, South India (Mishra and Jha 2017).
Neoraistrickia ramosa (Hart 1960) (Fig. 2.39).
Occurrence: Lower to Upper Permian of Collie-Muja Basin.
Description: Trilete. Amb triangular; sides straight to concave, apices rounded.
Laesurae extending almost to equatorial margin. Sculpture of exine irregular in
shape, size and distribution; bacculate, pilate or echinate.
Dimensions: 40–60 µ (15 specimens measured).
