, the gall lacks an operculum. A progressive necrosis extends up the gall wall with the advent of pupation; meanwhile the pupa opens an orifice on the wall with the aid of its frontal process and through body contortions. The abdominal spines help the pupa during these movements to anchor itself on the wall; it pushes part of its body out of the gall, when the exuvia splits and the adult emerges (Figure 14B, D). The outer wall eventually collapses, leaving the empty galls appearing as small holes on the host plant branches (Figure 14E, F).

Plants bearing galls of both cecidosid species were found mainly in the Coastal Range (Figs 8A, 14A). The climate in these valleys is typically austral Mediterranean; the vegetation is autochthonous, composed of sclerophyllous forests, palm communities and coniferous forests and steppe at higher altitudes (
