Dilophonotini of French Guiana

Dilophonotini of French Guiana:
Aleuron, Enyo, Pachygonidia, Unzela

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 French Guianan species not listed below, and there are some species not officially confirmed for French Guiana, 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.

Aleuron


Aleuron carinata
Black belts on anterior margins of abdominal segments; usually hidden except for first two broader belts.
Fw: nine more or less evenly dentate transverse lines between base of CuA2 and outer margin.
Distinct dark slightly concave arc from costa midway between cell and apex to midpoint of outer margin; dark region interior to arc; light region exterior to arc.
light area around small dark cell spot.


Aleuron iphis
Conspicuous abdominal white belt
Fw: Orangey-brown ground colour;
Fw: crossed medially/slightly obliquely by four narrow back lines, the basal most bordered with white basally and distally. Brown scales between the outer three, forming a prominent wide, dark band.
Aleuron chloroptera
No black belts around adomen
Almost uniform drab grey-green with nine, weak, more or less evenly dentate transverse lines between base of CuA2 and outer margin.
Small, darker crescents in submarginal area.






Aleuron neglectum
Similar to iphis.
Abdominal white belt much narrower than in iphis. Fw: black median lines indistinct posteriorly, except the basal most, which is bordered white basally but not distally, except at costal margin.

Enyo


Enyo cavifer
In both sexes forewing apex truncated, not sinuate (concave) as in Enyo gorgon. Ground colour chocolate-brown, almost black in some places. Fw discal cell narrower than in either Enyo gorgon or in Enyo taedium taedium.
Enyo gorgon
Forewing apex produced, with concave outer edge, not straight cut as in Enyo cavifer.
Lower half of wing noticeably darker than upper half.


Enyo lugubris
Body, wings dark brown.
Fw: large black patch covering most of outer half of wing.
Pale tan cell spot with small dark inner pupil,
Fairly straight median line to inside of cell spot.














Enyo ocypete
Fw: dark area not sharply defined, prolonged along antemedian line to posterior margin.
Discal spot small.
Male hw: diagnostic pale yellowish-white anal patch.
Females similar to Enyo lugubris lugubris, but have broad brown belt across base of abdomen (this belt either very narrow or absent in Enyo lugubris lugubris).

Pachygonidia


Pachygonidia caliginosa
 Fw very similar to Pachygonidia subhamata, but apex is pointed (not sinuate between Rs3 and Rs4, i.e. not dentate at the end of Rs4).
Outer margin slightly angulate at bottom of hollowed out region below apex, not as rounded (convex) as in subhamata or mielkei.
Hw: two median transverse pinkish-buff bands, similar to patterns of Pachygonidia mielkei and Pachygonidia subhamata.

Unzela

Japix and pronoe somewhat similar, but fw cell marking in stong contrast with surrounding area in pronoe; masked in japix. Outer, white aml in japix pronounced, very straight; in pronoe weaker, very irregular. Distinct, lighter, basal suboval patch in japix.


Unzela j. japix vi
Unzela pronoe pronoe
