Mexico: 1 male, Veracruz, 9.5 mi E Orizaba, Rd. 150, 7.vii.1962, F. Hill, ELM & J. Campbell ( ISU) ; 1 male, Veracruz, Rd. to El Vigía, 4 mi N Santiago Tuxtla, Hwy 180, 3 mi from Hwy. 180, 13.vii.1973, ELM ( ISU) ; 1 male, Veracruz, Rd. to Cerro San Martín from San Andrés Tuxtla , 8 mi from Hwy. 180, 14.vii.1973, ELM ( ISU) .
Etymology: The specific epithet is taken from the Latin guttatus (= drop), indicating the shape of the hypandrial median tongue.
Description: Male. Head. White in ground colour; vertical and orbital markings large, blackish brown; coronal suture black; frontal suture bordered with broad blackish brown band dorsally; frons with two pairs of blackish brown bands, internal pair narrow, external pair broad and not reaching frontal suture; gena blackish brown except eye margin white; eye black, IO/D = 0.7; ocelli white, ocellar field black; antennal socket bordered with blackish brown band; postclypeus with eight rows of blackish brown spots, fused with each other ventrally to form a large marking, ventro-lateral corner white; anteclypeus blackish brown. Antenna brown, scape darker. Mouth parts blackish brown.
Thorax. Prothorax blackish brown. Mesonotum pale brown; anterior surface of scutum blackish brown; anterior margin of lateral lobe and postero-lateral margin of anterior lobe of scutum black, posterolateral margin of lateral lobe and posterior part of anterior lobe white; scutellum brown, anterior margin blackish brown; postnotum brown. Metanotum pale brown, anterior lobe of scutum brown with white longitudinal line medially; scutellum brown, anterior margin blackish brown. Meso- and metapleurites blackish brown, with white longitudinal band medially.
Legs. Brown; fore leg except tarsus and hind tibia paler; all femora with pair of blackish brown spots ventrally; all tibiae with blackish brown band near distal end; middle femur with paler region medially.
Forewing ( Fig. 36B View Figure 36 ). Spots in cell a 1 apparent. Opposing spots in cell r large, almost touching each other. Proximal band broad, broadly interrupted just beyond fork of M + Cu, strongly constricted at anterior end in cell cua, including triangular pale spot. Median spots dense, some spots fused with each other, forming larger markings. Distal band apparent, broad in cell r 5. Spot on roof of cell m 3 apparent and broad. Submarginal spots apparent; spot in cell r 1 and m 3 smaller than others. Marginal clouds apparent and dark. Hindwing. Hyaline with faint brown marking in cell cup; veins brown.
Abdomen. Mostly black ventrally, each segment with blackish band dorsally and laterally. Terminalia. Clunial arm long and narrow, sickle-like in shape and forming free process apically. Epiproct ( Fig. 37E, F View Figure 37 ) chair-shaped, postero-dorsal margin with strongly projected transversal ridge, its median part with square-shaped thin keel; epiproct lobe long and wide, broader than long, narrowing dorsally, posterior surface slightly swelling. Paraproct: ventro-lateral band short, triangular; distal process long, directed upward. Hypandrium ( Fig. 37G View Figure 37 ): left process needlelike, almost straight, directed posteriorly; right process lamellate; median tongue small and short, length/width ª 2, nearly parallel sided and rounded apically, dorsal surface covered by weak denticles. Phallosome ( Fig. 37H View Figure 37 ): pseudoparameres long, needle-like. Aedeagus strongly projected dorsally, rectangular, sclerotized region extending to endophallus opening. Phallobase broadest at the middle, anterior margin rounded.
