Mauritius, Reunion. |
Biology |
Host: Nagia
linteola (Lepidoptera: Noctuidae) (Rousse & Villemant,
2012). |
Diagnosis
|
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 (Rousse & Villemant, 2012). |
Comments
|
Most of this genus is confined to the Pacific
region, but some species like E. agrestoria are
widespread outside of this area (Rousse & Villemant, 2012). The
ability of this species to colonize small islands has resulted
in the evolution of local types whose taxonomic status is
discussed by Gauld (1984). Since these fragmented populations
still share the same basic coloration and sculptural pattern,
Townes (1958) treated them as subspecies of E. agrestoria
Swederus. Within 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.; Rousse & Villemant, 2012). |
