Hagenulus (Careospina) baconaoi Kluge 1994:276 (male and female imagos, nymph, egg).

Holotype. Male imago, Province Santiago de Cuba, Río Baconao , Las Yaguas , 12-II-1989, N. Kluge.

This species was described by Kluge (1994) from specimens collected in La Yaguas (Río Baconao) and Toa (Eastern Region) and Soroa (Western Region). The color pattern resembles that of Careospina hespera sierramaestrae but the color is darker and more extensive on posterior terga, and the labrum is broad with a deep, broad anteromedian margin.

Ecology. The distribution of this species has been considered as rare and patchy ( Aldana and Fonseca 2001, Hernández and Cala 2003). Individuals were captured along stream banks in areas of rapid waters at an altitude of 54 m. All specimens in the collection resulting from thesis projects were found below 600 m, with most collected at altitudes between 0 and 250 m. Nymphs were captured throughout the year, suggesting that adults may emerge at any time of the year.

Geographic distribution. The species is recorded from Soroa in the Western Region and in the Eastern provinces of Guantánamo and Santiago de Cuba. There are also 82 specimens in the collections from the provinces of Granma and Holguín, but no records from the Central or Central-East regions. This finding is interesting because the populations appear to be geographically isolated ( Fig. 11 ). However, it is possible that this species has been overlooked in other regions because of its sparse distribution.
