Hagenulus (Turquinophlebia) grandis Kluge 1994:265 (male and female imagos, nymph, egg).

Holotype. Male imago, Province Santiago de Cuba, Arroyo Paco ( Río Palma Mocha ), 24-II-1989, N. Kluge.

Like Borinquena sexta , the species was described from specimens collected in Arroyo Paco, a tributary of the Río Palma Mocha. Kluge (1994) states this is the largest leptophlebiid in Cuba. The gills are broadened basally, the lateral margins of the mandible are strongly curved, and the labrum is broad, triangular, and cleft distally (without denticles).

Ecology. Aldana and Fonseca (2001) reported these nymphs to be scattered and rare as only 11 specimens were found in two localities in Holguín Province. They were found by lifting rocks in the rapids of relatively cold water streams with a depth of approximately 100 cm and scanty vegetation cover. The bottom was bedrock.

Geographic distribution. Distribution is limited to the Eastern Region of Cuba ( Fig. 9 ), specifically the provinces of Santiago de Cuba (type locality) and two locations in Holguín Province: 3 nymphs, Moa , 6/ 24-VI-2000 ; 8 nymphs, upper basin of the Río Mayarí .
