Type material. Holotype (): Quebrada Segunda Ref. Nac. Fauna Silv. Tapanti, 1250 m, Prov. Cartago, Costa Rica, G. Mora, mar 1992, L­N 194000, 560000// 741269 ( INBio).

Derivation of name. From condylus (Greek= knuckle, knob, protuberance) for the humeral prominences.

Diagnosis. This species is easily distinguished from all other Ocnosispa by the knoblike humeral protuberances, the angulate frons, and the two longitudinal vittae on the pronotum.
