Holotype. Male imago, [Province Artemisa], Río Cuzco , March 1965, P. Alayo.

The species was defined based on specimens collected in the Río Cuzco around Soroa and other localities in the Western Region ( Peters 1971); it was also reported from the Río Soroa by Kluge (1994) who established the subspecies. All species of Careospina have a short third segment of the labial palpi.

Ecology. Nymphs are found under stones in several microhabitats ( Álvarez 2007) at depths of 1 cm or greater, mostly in rapids and backwaters but preferring rocky bottoms (Kluge 1994). Specimens in the collections representing theses (of diploma) were found exclusively at altitudes less than 250 m, indicating a preference for low altitudes. Nymphs were collected in January, May and June, and Kluge (1994) also reported nymphs in the months of March, April, October, November and December, indicating an apparently non-seasonal life cycle. The adults may emerge in any month of the year.

Geographic distribution. This subspecies is very abundant in the Western Region, especially in the streams of the Sierra de los Órganos, and is also found in the Central Region ( Fig. 10 ).
