Argentina: Macroglossini
Hyles and Xylophanes

This checklist will become more refined on a species by species basis 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.

Since I am often asked to identify species from digital images, and since those images frequently show the moths at rest with the hindwings and abdomen hidden, I have arranged the images in accordance with my perception of forewing and thoracic characters: predominent markings, shape, colour. I have also included information about size, and most often display the moths in spread position as those same abdominal and hindwing features are often very useful when available.

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

Hyles annei
San Juan

Hyles lineata
Catamarca, Cordoba, La Rioja, Salta, Santa Fe (JEF), Tucuman,

Hyles euphorbiarum NV
Buenos Aires, Catamarca, Cordoba, Corrientes, Chubut, Jujuy, La Pampa, La Rioja, Mendoza, Misiones, Neuquen, Salta, San Luis, Tierra del Fuego, Tucuman

Thorax: dark brown tegulae; dark brown head.
Dark brown, dark green, distinct, apical, transverse post median line.
Dark brown shading in cell area.

Xylophanes docilis
Fw o. m. almost straight.
Almost straight, prominent pml meets i. m. close to body.
Three very weak slightly crenulated inner pm lines.
Thin, distinct, dentate sbtrmnl line, greenish inner shading.
Dark brown stripe down middle of abdomen.

Greenish shades fade to brown.

Jujuy, Salta

Xylophanes epaphus EB

The head, body and lower wing are very similar to Xylophanes docilis, although the mesial line is absent on the abdomen.
The forewing apex is much more produced in epaphus, and the outer margin is very convex south of the hollowed out region below the apex.

Xylophanes anubus anubus

Xylophanes anubus is similar in forewing pattern to several species in the group above, especially X. docilis, but note absence of dark brown tegulae, which are instead concolorous with rest of thorax and abdomen.
Also note absence of dark line down center of abdomen. The forewing pm line of anubus is thinner than that of docilis, and it also meets the inner margin closer to the anal angle.


Xylophanes fosteri EB

Xylophanes elara EB

Xylophanes loelia

Xylophanes ceratomioides
Fw o.m. slightly scalloped.
Abdomen: three narrow, longitudinal lines; outer lines posteriorly divergent and expanded into triangular spots.
Costa: conspicuous subapical, apical black spots, largest subapical spot triangular with inner point directed basally.
Median area running out to apex: pale brown with scattered black scales on veins; discal spot small, black.
First four pm lines dissipate preapically before reaching costa, weak fifth line runs to apex. First line slightly sinuate.
Second-fourth lines very scalloped near inner margin.
Oblique postmedian band dark with sinuate black lines within it, inner edge slightly undulate, outer edge deeply excavate from CuA2 to just above M3, forming a pale brown, oval patch; marginal area with black vein spots.

Xylophanes th. thyelia
Xylophanes thyelia has visible characters making it similar to members of the Xylophanes ceratomioides group, but it is a much smaller species.
The head has a dark longitudinal line, bordered ventrally with buff, above the antenna. The tegula have a dark brown median line, bordered on each side by a pale grey stripe, irrorated with pale purple.
The abdomen has a brown midline, bordered by narrow grey lines; a brown lateral line present on segments 2-4, bordered ventrally by a pale buff line that continues posteriorly to segment 7.
The forewing upperside is dark brown and buff. There is a short dark line present basal to the first postmedian line, reaching as far as the discal spot. First, second and third postmedian lines arise almost from the wing base and are quite oblique. The first postmedian line reaches to just beyond M1; the second postmedian line reaches Rs4; the third and fourth postmedian lines very narrow and close, sometimes fused for part of their length distally, running from Rs4 to M3, below which they become a diffuse series of minute spots (continuous and distinct below M3 in Xylophanes thyelia salvini).
The area between the second and third postmedian lines, where they overlap, is conspicuously pale. The fifth postmedian line runs from the apex to M3 as a gradually broadening triangular patch. There is an apical area bounded by the costa, fifth postmedian line and Rs4, and the tornal area bounded by M3, the second postmedian line and CuA2, both pale brown and buff, with scattered individual black scales; Rs4, basal to second postmedian line, highlighted with buff over distal half.
The forewing underside has three dark brown or black, parallel and equidistant postmedian lines.
The hindwing upperside is an almost uniform grey-brown. The median band is barely visible. in the male, the hindtibia have long scales dorsally and ventrally, thus appearing very broad and compressed.

Xylophanes titana

Xyloph. nabuchodonosor

Very distinct species, unlikely to be confused with other species.

Xylophanes pistacina
Fw apex slightly produced, pointed.
O. m. hollowed out below apex, evenly convex to anal angle.
G.c. variable: greenish-buff.
Three subparallel am lines, angled at CUA1.
First two pm lines form broadly preapical, prominent, straight, slightly oblique, dark band.
Third pml very faint.
Fourth pml distinct, vein dots.
Fifth pml curved from apex, continuous with greenish olive patch from M2 to M3.

Xylophanes porcus EB

Xylophanes tyndarus EB

X. chiron nechus, OR

Xylophanes marginalis EB

Xylophanes pluto
Tegulae: dark brown edges.
Fw apex slightly produced, pointed.
O. m. hollowed out below apex, evenly convex, smooth or slightly crenulate, to anal angle.
Five subparallel am lines, evenly convex.
First pml thin but distinct, slightly oblique, recurved toward body at costa.
Additional pmls very dentate, less distinct.
Prominent white subapical, basal-median suffusions.

Xylophanes t. tersa
Tegulae: strong orange midline.
Abdomen: four strong pale brown lines over orange g. c., weaker midline, outer lines.
strong orange lateral bands
Fw o.m. slightly convex below hollowed out subapical area.
1rst, 2nd pmls fused basally.
3rd, 4rth pmls thin over light background.
5-8th pml thicker, but weak basally.
Hw pale yellow spots generally elongating toward apex, more basal closer to margin.
Thin orange suffusion above cream fringe.

Xylophanes resta
forewing length: 36-41 mm.
Tegulae: weak golden midline.
Thorax: grey medial band, bordered laterally, divided medially by brown lines, continuing along abdomen, becoming faint after first two abdominal segments.
Fw: characteristic brown tone,
First pml very strong basally, disappearing towards apex;
second pml fused basally with first; fourth pml less than half width of first.
Hw pale yellow spots larger than tersa,
more distal closer to margin.
