1. Notocearagryllus leipnitzi Martins-Neto, 2002 b

Etymology. In honor of the foraminiferologist Prof. Dr. Itamar Ivo Leipnitz (UNISINOS-RS).

Holotype. RGMN-T029, Martins-Neto Collection, housed at the Sociedade Brasileira de Paleoartropodologia – SBPr.

Type locality, type stratum and age. As for Notocearagryllus dutrae Martins-Neto.

Diagnosis. As for the genus.

Description (Holotype, Fig. 1 C). Male tegmen 25 mm long as preserved (around 2/3 of the probable total length). RP, CuA and pre-lanceolate cell partially preserved. Speculum fairly square, with the anterior margin slightly curved than the posterior one. Anterolateral margin as long as the posterolateral one. sp1 reaches the distal part of the posterior margin and the apical part of the anterolateral margin, parallel to the anal margin, converging on sp2; sp2 reaches the distal part of the posterolateral margin and the apical part of the anterolateral margin, close to the sp1 extremity. CuA secondary branches beginning above the speculum, and zigzag-shaped at their base, perpendicularly deflecting toward the apical margin, then running, slightly convergent, alongside the anal margin. Intraspecular cells numerous immediately under the speculum and also after it. Chords notably curved. The d vein partially fused to CuP, converging towards CuA. The d-am crossvein situated at the boundary of both anterior and anterolateral margins of the speculum. Apical part of d connected to the apical part of the posterolateral margin of the speculum by a long cross-vein. The area below the posterior margin of the speculum of similar width to the adjacent areas (area below the anterolateral margin of the speculum and area between the posterolateral margin of the speculum and the most proximal CuA secondary branch) and filled by parallel cross-veins.

Remarks. This specimen was originally described by Martins-Neto (2002b) under the collection number RGMN-3000, now removed to a definitive collection number RGMN-T029 at the same Institution (SBPr).
