Holotype. Male imago, Province Santiago de Cuba, La Alcarraza (Guamá), 4-II-1989, N. Kluge.

Caribaetis alcarazzae was described by Kluge (1992a) from La Alcarraza in the Sierra Maestra. It is distinguished by its highly contrasting color pattern with abdominal terga 2 and 6–7 very dark on a pale background, as compared with C. planifrons where markings occur on a yellowish background.

Ecology. Another 18 nymphs have been reported by Rodríguez and Pérez (1998) from the Río Jibacoa, but comparison of a nymph from the type locality with these specimens would indicate that the Río Jibacoa material may belong to Caribaetis planifrons and not to C. alcarrazae (González-Lazo personal communication). Considering this and the report of Cañizares (1998), the species is considered rare in Cuba.

Nymphs have been collected in the months of November through January. Kluge (1992a) reported the species in February.

Geographic distribution. Formerly limited to La Alcarraza in the Sierra Maestra in the Eastern Region, we recently determined a nymph from the Río Mayarí with the label “03-II-01 cols. Andana y Fonseca” which expands the distribution to the Nipe-Sagua-Baracoa Massif, also in the Eastern Region ( Fig. 4 ).
