(Troglodytidae; Ϯ Sumichrast's Wren H. sumichrasti) Gr. ὑλη hulē woodland, forest; ορχιλος orkhilos wren; "Hylorchilus,1 new genus. Type. Catherpes sumichrasti LAWR. ... Like Microcerculus, this genus is characterized by the plainness of its dark brown plumage, the tail and wings being unmarked, as is most of the body. The secondaries are almost of the same length as the primaries, and the tail is short and spiky in form, being made up of soft slender feathers narrowed gradually at the tip. The tail is so short that it does not reach to the end of the outstretched feet in the dried skin. The body is short and stout, with strong legs and feet as in Microcerculus. The bill, however, is more as in Catherpes, being long, unnotched at the tip and with similarly narrow, oval, slit-like nares ... It forms a distinct type of Wren of generic value and having Microcerculus as its nearest ally. Some of its characters indicate a close relationship to Catherpes as well, so that its position appears to be that of an intermediate group between these two genera. ... These birds inhabit the gloomiest recesses of the heavy tropical forest, keeping about jutting rocks on steep hillsides, where the forest is so dense that the undergrowth is sparse and the sun scarcely penetrates to the ground ... 1 ὑλη, forest, and ορχιλος, wren, in reference to the habits of the type species."
