Sclerurus caudacutus caligineus

Historically known from only two or three localities in the PCE, S. c. caligineus is on the brink of extinction ( CEMAVE, 2018). Three specimens, including the holotype, were collected in 1952 ( MZUSP 36415 , 37367 and 37368; Pinto, 1954), and another three in 1957 ( MZUSP 39041 , LACM 26867 and 26868), at Usina Sinimbu. Another was collected in São Miguel dos Campos ( MNRJ 32033 ) and three at the Murici Ecological Station ( MNRJ 32034 , 32035 and 34537) in the 1980s. The lowland forests of Usina Sinimbu and São Miguel dos Campos were entirely transformed into sugar cane plantations and S. c. caligineus has currently been recorded only at the Murici Ecological Station, where it is very rare ; during more than ten years of mist netting, only one individual was captured there in January 2017.
