Cuervo & J. Cruz; 20 heteromorphic males, 20 homeomorphic males, 20 females, 20 tritonymphs ( ZISP), 3 heteromorphic males, 7 homeomorphic males, 4 females, 3 tritonymphs, 1 protonymph ( UMMZ) from nest of Tachornis phoenicobia in palm leaf roof top of shed, CUBA: Artemisa, park 1 km N of Las Terrazas, 22°51'11.3" N 82°56'18.9" W, 15 May 2014, coll.
