Other material examined
PUERTO RICO: Isla Mona: same data as holotype, 1 imm. (EME sel_846); Camino de los Cobros, VI.2006, A. Puente-Rolón, SCC06_059, under bark of Bursera, 1 imm. (CAS sel_502); Maricao: Bosque Estatl de Maricao, 18°08'51.2"N, 66°59'35.0"W, 10.VI.2006, 700–800 m, S. Crews, A. Puente- Rolón, serpentine forest, 1 imm. (CAS sel_440).
Etymology
The specific name comes from the Taino word ‘amona', the indigenous name for the type locality. It is to be treated as a noun in apposition.
Diagnosis
