Willemsegryllacris n. gen.
Diagnosis: Size and shape of body more or less similar to those other medium size gryllacridines (Fig. 84) as Ocellarnaca and Eugryllacris . Head with a medium size and with a very prominent median ocellus, occupy much of the frons (Fig. 85); lateral ocelli rounded and small, space between antennal cavities as wide as 1.5 time the wide of scapus; fore coxa with an unarticulated spine, legs moderately short, robust, with five pairs of movable ventral on fore tibiae and four pairs on ventral margin of middle tibiae; wings well developed, long and little surpassing the apex of abdomen; hind wings hyaline. Abdomen without traces of femoro-abdominal apparatus; 9 th tergite of the male with two lobules (as Zalarnaca but more prominent to the new genus) and with a very small pair of hooks, mostly covered by the lobules; paraprocts and cerci simple (Fig. 86), 10 th tergite short and inconspicuous; male subgenital plate moderately small, transverse, with moderately long and simple styles. Female unknown.
Included species: Type species: Willemsegryllacris barnesi (Chopard, 1937) n. comb. (before Gryllacris barnesi).
Etymology: Dedicated to Dr. Luc Willemse as acknowledgement for his help, plus typical terminationgryllacris common to genera of this family.
Comparisión: Willemsegryllacris is similar as Ocellarnaca to the very well developed median ocellus, but in the new genus it is more prominent. Willemsegryllacris differs from Ocellarnaca in a not lobate 9 th tergite and hooks very little developed. From the other Gryllacrae genera, the new genus differs in its very well developed median ocellus, hind wings hyaline in contrast to Pardogryllacris, Lyperogryllacris and Xanthogryllacris .
