Hylophilus grandicornis was never described. Pic (1952) refers to this taxon, and the Zoological record (1923, vol. LX) indicates a reference for this description (Mélanges Exotico-Entomologiques, Vol. 38, p. 4), but after a careful check, I found no such description in the volume cited, nor in the entire publications by Pic in Mélanges Exotico-Entomologiques. I also surveyed a large number of Pic’s papers where Aderidae were discussed and could not find the trace of a description of this taxon. Winkler’s catalogue, 1927 does not list it either. Leaning on the ZCN article 11.1 ( ICZN, 1999), I therefore consider that the name Hylophilus grandicornis Pic is not an available name, although, there is a single specimen from Pic’s original collection at the MNHN labelled “ Hylophilus grandicornis n. sp. ”. I suppose that the description has remained in litteris.

In 1927, Pic described a variety of Hylophilus grandicornis under the name Hylophilus grandicornis v. obscuricornis . The description is limited to 3 words (Antennis nigro-piceis) and was made in reference to grandicornis s. str. After examining the type specimen of this taxon in Pic’s collection (MNHN), it appears to be a bona fide species. I therefore consider that the name Hylophilus obscuricornis Pic, 1927 is available, and that this taxon should be placed in the genus Zarcosia , under the name Zarcosia obscuricornis (Pic, 1927) , comb. nov.

Finally, the type in litteris of Hylophilus grandicornis is similar to that of Hylophilus obscuricornis Pic, 1927 and belongs to this taxon.
