Notocearagryllus arturandradai Martins-Neto , n. sp.

(Pl. IA; Fig.1 B)

Etymology. In honor of the geologist Artur Andrade (CPCA, Crato, Ceará).

Holotype. CPCA - 3561, Centro de Pesquisas da Chapada do Araripe, Crato, Ceará State.

Locus and Stratum-typicum. As for Notocearagryllus dutrae Martins-Neto.

Diagnosis. Male tegmen with d2 distally fused with d1 before the anterolateral margin of the speculum; h6 distally fused d-m. Speculum with two straight parallel cross-veins. The first infra specular cross vein continuous to sp1. Area below the speculum wide and filled by relatively long and parallel cross-veins. CuA secondary branches sinuous.

Discussion. Notocearagryllus arturandradai Martins-Neto , n. sp. differs from N. dutrae Martins-Neto, 1998 , in having d2 distally fused to d1 before the anterolateral margin of the speculum (close to CuA in N. dutrae ). Additionally, N. arturandradai n. sp. exhibits notably sinuous CuA distal secondary branches (straight in N. dutrae ) and the first infraspecular cross vein continuous to sp1.

Description ( Fig. 1 B). Male tegmen 17 mm long with fairly wide costal area filled with pectinate and relatively long cross-veins. ScP slightly curved, reaching the costal margin at the boundary with the apical margin. Space between R and M filled by a lanceolate cell, with at least five perpendicular cross-veins. R and M notably divergent, forming a wide triangular area. M reaches the apical margin above the apex. CuP and 1A base forming a Z-shaped structure. Chords (extension of CuP and 1A) notably curved. 1A partially fused with 2A at distal part of the “Z”. The area below the speculum is filled by fairly parallel cross-veins. Harp with at least six slightly curved chords, the last aligned to the anterior margin of the speculum and the boundary between the lanceolate-cell and the lancet-like cell. Area between the last harp’s chord and the chord filled by transverse cross-veins, forming a belt of quite homogeneous cells. Apical secondary branches of M sinuous.
