Smerinthini thumbnails

French Guiana Dilophonotini:
Aellopos, Eupyrrhoglossum, Nyceryx, Perigonia

This tentative checklist will become more accurate as images and information are sent to me. If you would like to assist in the development of this worldwide Sphingidae data/image base, please send info and images to Bill Oehlke.

I have arranged the images in accordance with my perception of wing characters: predominent markings, shape, colour, size.

There are probaby some Peruvian species not dlisted below, and there are some species not officially confirmed for Peru, although I think they have a good chance of being found there.

Females often have a wing shape or pattern that differs from the males. I hope some day to also have a thumbnail checklist for the females.


Aellopos ceculus
Cell spot usually masked by dark band. Fws: dark brown with paler marginal area and slightly paler sinuate post median bands divided by thin darker lines.
Slightly paler am band also divided.
Hws: Broad, transverse yellow band, widening near anal angle.

Aellopos fadus
Wide white stripe across the abdomen. Wings are dark brown. No black cell spot. Outer band (upper half divided in two by dark line) of translucent white spots more extensive than in titan; inner band also divided in two. Hw: pale patches along costa and inner margin reduced, compered to titan.

Aellopos titan titan
Wide white stripe across the abdomen. Wings are dark brown. Fw: black spot end of cell, two bands of translucent white spots. Lower band (cell to inner margin) divided in two by dark line. Hw: pale patches along costa and inner margin.


Eupyrrhoglossum sagra is the only member of its genus with a presence in French Guiana.

Note white/pale spot/crescent in middle of forewing subterminal area.

Note bright yellow hindwing fringe.

Its markings are beautiful and distinct.

Eupyrrhoglossum sagra


Nyceryx maxwelli: Several dark patches against lavender-grey ground colour. Similar to Nyceryx continua cratera but apex of hindwing upperside brown and tornal area not yellow. Hindwing upperside with yellow basal area not extending beyond 1A, and apex brownish-orange (not dark brown).

Nyceryx coffaeae
Almost uniform dark brown ground colour. Outer margin not deeply hollowed out below apex, instead o.m. divided into two roughly equal, almost straight (slightly concave) edges with slight bulge at their juncture.
Large, slightly darker trapezoid with base along inner margin, extending to bottom of cell.

Nyceryx ericea
Prominent diffuse, dark arc, upwardly convex, from near midpoint of costa to anal angle.
Thin, dark, scalloped arc from apex to anal angle. Semitransparent spots in the distal half of the forewing.

Nyceryx tacita
Prominent small white triangular patch in upper half of subterminal area.
Strong dark green suffusions over dark brown in costal regions.
Large dark triangular patch with base from body to midpoint along inner margin with right angle to costa.
Significant pale lines define other dark patches.

Nyceryx riscus
Diffuse, very dark, somewhat angular arc from apex to anal angle. Fine but distinct lines over reddish brown ground colour.
Lacks significant addition markings on forewing.

Nyceryx stuarti
Two black, subparallel, concave lines determnie a smooth arc from apex to anal angle with marginal area and space between two black lines filled with light grey scaling. Small light grey patch along inner margin. Fine lines over reddish brown ground colour.


Perigonia ilus
Lacks solid, dark apical crescent to mid bulge, instead a diffuse, dark arc with lighter internal scaling.

Perigonia lusca : Fw: Dark, slightly irregular, inwardly concave, thick line runs from apex to anal angle. Prominent, straight, dark aml outwardly shaded in dark brown more widely along inner angle, tapers toward costa. Outer margin, oblique, almost straight. Small black dot at base of costa midpoint, slightly larger black, short black streak in cell. Hw yellow band very variable.

Perigonia pallida
Similar to Perigonia stulta but generally paler, forewings narrower. Hindwing upperside very similar to Perigonia stulta but brown border narrower and basal patch deeper yellow-orange tint.
Both species with solid, dark crescent apex to midwing bulge; pallida with less pointed apex.

Perigonia stulta: Crenulations of forewing outer margin are variable in degree of development, but greatly produced near midpoint. Forewing upperside lacks distinct grey-brown or pale brown lunate patch on the outer margin. Forewing underside submarginal line distinct at least from the apex to M2, bordered with grey distally.
