Zebragryllus sp. 1 Figs 10–11 Diagnosis This female is similar to that of Z. wittoto, Z. guianensis, and Z. nouragi by the ‘zebra’ pattern on the hind legs (Figs 10A–B, 11J–K). The fore and mid legs have only a few whitish areas on the base of the femora and dorsal surface of the tibia (Fig. 11E–F, H–I). The tympanum is widely open on the outer face proximal portion of the fore tibia (Fig. 11E, G). However, it differs from the species mentioned above in the longer tegmina, reaching up to the second abdominal tergite (Fig. 10C–D), which is more similar to Z. nauta. The first two segments of maxillary palpi are small and subequal in length; the third and fourth are as long as the first and second together; the fifth is longer than any other segment, with the ventral margin slightly arched and the medio-distal portion obliquely truncated, dorsal margin straight and the apex rounded. The only whitish area of the maxillary palpi is the ventral surface of the mediodistal portion; the remaining is dark (Fig. 11D). The abdomen is mostly black but has whitish bands on the anterior and posterior margins of each tergite (Fig. 10A–B). The supra-anal plate is subtriangular, with a distal margin rounded (Fig. 10E). The subgenital plate is similar to that of Z. nouragi, with the posterior margin sinuous in lateral view and concave in ventral view (Fig. 10F–G). The ovipositor is straight and very short, shorter than the hind tibia, with a triangular apex (Fig. 10A–B, 10H–I), similar to Z. guianensis. The copulatory papilla is quite unique, with an ovoid shape, laterally sinuous, and a more membranous dorsal portion (Fig. 11A–B).
