DISTRIBUTION:

Adeloneivaia cayennsis (approximate wingspan: males: 78-90mm; females: larger) flies in
French Guiana: Cayenne: Kaw Mountain area; Saint Laurent du Maroni; Belizon; at elevations of 80-290m.

This species is very similar to other recently (2011 Brechlin & Meister) described or elevated species as well as to Adeloneivaia jason:
Adeloneivaia orientoandensis from Peru: Amazonas; Madre de Dios; and from Ecuador: Napo; at 500-1200m;
Adeloneivaia leopoldina from Brazil: Espirito Santo;
Adeloneivaia kawiana from French Guiana: Kaw;
Adeloneivaia orientoboliviana from Bolivia: Chuquisaca; at 1180-1480m
Adeloneivaia jaustralica from Bolivia: La Paz; Santa Cruz; and from Peru: Amazonas; Madre de Dios; Junin; and from Ecuador: Napo; Pastaza; 800-2000m
Adeloneivaia jamazonica from Peru: Amazonas; San Martin; Cusco; 800-3200m
Adeloneivaia nigripuncta from Nicaragua: Jinotega;
Adeloneivaia jason from Mexico: Oaxaca.

For some species, ranges may be much more extensive than indicated above.

Based on the single image of a male Adeloneivaia cayennsis in the Entomo Satsphingia journal, I offer the following description of that specimen. I do no tknow how consistent these characters would be in a series of specimens.

Solid lavender basal area is separated from dark orange median area by dark slightly concave am line. The cell spot is a small white dot with a dark outline. Most of the subterminal area is orange, concolourous with the median area. The outer margin is straight, slightly obliqueand is inwardly traced by a narrow band (wider near the apex) of lilac scales. The very slightly apical pm line is flexed slightly downward outside the cell.

This species is very similar to A. jason, but I believe jason is more yellowish than orange, and that jason has a forewing outer margin that is very slightly s-shaped with a slight outward projection just before the anal angle.

French Guiana Systematics has a moth depicted as A. jason which might be A. jason, or it could be A. kawiana or A. cayennsis. Wing shape suggests one of the new species (not jason). It is a bit smaller than indicated for kawiana or cayennsis which are same size, but seems to have the more restricted, more intense red on the hindwings which indicates cayennsis. It also has the lilac terminal area of cayennsis, but lacks the downward turn in the pm line.

The species name, cayennsis is indicative of a specimen type location in Cayenne, French Guiana.

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

Adeloneivaia cayennsis fly in January-February, August, December. There are probably additional flight months, and this moth probably broods continuously.

ECLOSION, SCENTING AND MATING:

Adult Adeloneivaia cayennis moths emerge from pupae, and males are smaller than females.

Mating probably begins shortly after dusk with a likely calling period from 10:30 pm. to 1:00 am.

EGGS, LARVAE AND PUPAE:

Night-flying females lay translucent eggs on host plant leaves.

Larvae pupate underground in small chambers.

Care of larvae and pupae should be as for any Neotropical species.

It is hoped that this alphabetical listing followed by the common name of the foodplant will prove useful. The list is not exhaustive. Experimenting with closely related foodplants is worthwhile.
