Material examined. 9 males and 9 females ( ZISP 6269–6286 ) from Tolmomyias sulphurescens (von Spix, 1825) (Tyrannidae) , COSTA RICA , Rincón de la Vieja National Park , Cordillera de Guanacaste Mts., 10°46’N , 85°18’N ; 16 August 2009 , collectors I. Literak , O. Sychra and M. Capek. Nycteridocaulus pectinatus is a remarkable species within the genus Nycteridocaulus in having a unique structure of terminal lamellae in males, which are strongly indented and resemble a hair comb. The species was previously known from Tolmomyias flaviventris (zu Wied-Neuwied) ( Tyrannidae ) in Trinidad ( Atyeo 1966a ). This is the first finding of this species in Costa Rica, and Tolmomyias sulphurescens is a new host species record for this mite.
