Diagnosis. Echthromorpha spinator is a dark species characterized by the apical black spots on fore wing.

Description. Seyrig (1932).

Host records. Nagia linteola ( Lepidoptera : Noctuidae ).

Comments. Most of this genus is confined to the Pacific region, but some species like E. agrestoria are widespread outside of this area. The ability of this genus to colonize small islands gives an interesting example of local differentiation, with the development of local types whom taxonomic status is discussed by Gauld (1984). Considering that “most of them” share the same basic coloration and sculptural pattern, Townes (1958) treated all these local forms as subspecies of E. agrestoria Swederus. For the E. agrestoria species group of the Malagasy subregion it appears that E. spinator forms a homogeneous group, including the former E. agrestoria macula (Brullé) of Reunion and E. agrestoria spinator (Fabricius) of Mauritius (Madl, pers. com.). This species is mostly characterized by the densely punctate mesosoma and the black spot on apex of fore wing, making it distinct from the other members of the E. agrestoria complex.

Distribution records. Reunion. Mauritius.
