Phylus melanocephalus

Paler specimens of P. melanocephalus were long referred to as separate species Phylus palliceps, distinguished in particular by having a pale head, P. melanocephalus being restricted to insects with a dark head. Pagola-Carte et al. (2005) found no morphological or habitat differences between specimens referred to the two supposed species, and a continuous gradation of colour, and concluded the two should be synonymised. ==References==
