Jean-Michael Maes reports it in Nicaragua: Nueva Segovia, Esteli, Jinotega, Matagalpa, Granada, Chontales, Zelaya, but those reports may refer to the more recently described Automeris jinotega and Automeris managuana, both of which have hototypes in Nicaragua.
The image below, however, does seem to confirm a presence in at least northern Nicaragua. Other images I have seen as montezuma on Jean-Michael's CD, I have classified as managuana, jinotegana, and celata. I may be in error, but the CD was produced before the newer species were described in 2011.

The forewing ground colour is brown mixed with grey. The basal area is dark and is bordered by a convex am line. The pm line is dark, strongly preapical and marked as indicated above. The cell area is slightly darker than its surroundings and is marked by a series of yellow dots. The forewing apex is very slightly produced and pointed.

In his Hemileucinae 2002 Lemaire recognizes four species in the Automeris montezuma Species Group 7:
Automeris montezuma HT Mexico: Jalisco; mfwl: 29-32mm (28);
ground colour grey (fading to brownish grey), with slightly darker basal area, and silvery suffusion in median area;
strong presence of yellow gold
at vein pm line junctures, at apices of cell mark and along outer edge of am line
Automeris celata HT Costa Rica: Cartago; mfwl: 30-35mm (5); ground colour: yellow-grey-brown with heavier grey suffusion in basal area; fw pm line:
inwardly highlighted by diffuse narrow
band of lighter-yellow scales with continuous suffusion of yellow into the median area; pm line relatively thin, almost concolorous with subterminal area;
outer margin slightly convex
Automeris escalantei HT Mexico: Chiapas; 32-35mm (12)
Fw outer margin straight to slightly convex; not at all oblique. Pm line, inwardly lightly graced with yellow-gold, subparallel to outer margin.
Irregular cell concolorous, but marked by black spots at various apices.
Ground colour: uniform, drab grey or brown with light suffusion of silvery scales, reduce contrast in basal, median, marginal areas.
Automeris pallidior HT Guatemala: Baja Verapaz to Costa Rica (at least to Guanacaste), possibly
from southwestern Mexico to Panama; mfwl: 26-30mm (15); very similar to jinotegana and managuana.
Lemaire indicates additional range data (countries) for the four species listed above. Some of that data, other than Holotype may apply to the newer species listed
below that were not recognized by Lemaire as distinct. The black numbers in parentheses indicates the sample size. Forewing length and range may change considerably as
more specimens are sampled.
In Entomo Satsphingia, Jahrgang 4 Heft 1 23 03 2011 by Brechlin and Meister, those authors add nine species
to the Automeris montezuma Species Group 7:
Automeris juarezia HT Mexico: Oaxaca; 900-1050m; mfwl: 35-36 (8) uniform darker grey or grey brown ground colour; concave, broadly preapical pm line
Automeris altapazia HT Guatemala: Alta Verapaz; 1200m; mfwl: 37mm (1); specimen in Lemaire 2002, Plate 60: 10 is A. altapazia
Automeris wernermeisteri HT Mexico: Oaxaca; 1023-1530m; mfwl: 32-33mm (12); pale ground colour; thick, dark pm line very concave;
very small hw ocellus; hw median band divides wing into inner 2/3 and outer 1/3; similar to A. pallidior
Automeris managuana HT Nicaragua: Managua; 865m; mfwl: 30mm (1); lighter median area, contrasting om area,; lines outlined in lighter scales on facing sides
Automeris jinotegana HT Nicaragua: Jinotega; 1185-1280m; mfwl: 27-30mm (7) uniform, dark grey-brown, with little contrast; both small fw cell mark and am line scarcely visible
Automeris paracelata HT Costa Rica: Puntarenas; 900m; mfwl: 30-32 (5); very similar to A. celata, but more distinct fw pm line
Automeris choco HT Colombia: Choco; 1500m; mfwl: 28mm (1); evenly dark brown; slightly convex pm line, subparallel to slightly convex outer margin
Automeris stumpei HT Costa Rica: Limon; 1430m; mfwl: 34mm (1) almost straight pm line, subparallel to outer margin; fw: almost uniform light brown ground colour;
hindwing ocellus with tiny white pupil
Automeris knorkeorum HT Mexico: Oaxaca; 677-1023m; mfwl: 30-32mm (5); fw: light coloured, bright; fw pm line slightly concave; small hindwing
ocellus; hw median band divides hw in half.
Larvae feed on Robinia pseudoacacia.
