Notocearagryllus arturandradai Martins-Neto

n. sp.

Notocearagryllus arturandradai Martins-Neto   , n. sp.

(Pl. IA; Fig. 1 View FIGURE 1. A 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 d 2 distally fused with d 1 before the anterolateral margin of the speculum; h 6 distally fused d-m. Speculum with two straight parallel cross-veins. The first infra specular cross vein continuous to sp 1. 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 d 2 distally fused to d 1 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 sp 1.

Description ( Fig. 1 View FIGURE 1. A 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 1 A base forming a Z-shaped structure. Chords (extension of CuP and 1 A) notably curved. 1 A partially fused with 2 A 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.
