Ocellarnaca Gorochov, 2004

Type species: Ocellarnaca ocellata Gorochov, 2004

Discussion. The genus is closely related to Eugryllacris . It differs by the somewhat brachypterous wing condition resulting in rather short oval fore wings with subparallel veins, and the large conspicuous median ocellus. The projections from male ninth abdominal tergite are larger and more diversified and often consist of a wide trunk with a narrow appendage ( Fig. 23 ). The color pattern of the hind wings with light cross-veins and dark cells agrees with the condition in Eugryllacris , but in Ocellarnaca the fore wings show the same color pattern while in Eugryllacris the fore wings are uniformly colored or with different color pattern.
