Description.
Imago (
Fig. 55
). Labial palpus with second segment rough-scaled ventrally, third segment as long as second, apex acute. Antenna more than half forewing length. Clypeus with ventral margin rounded. Posterior area of sitophore with four campaniform sensilla in line except left side; anterior area with seven campaniform sensilla. Ocellus present. Forewing (length/width ratio 4.3) with slight tufts of raised scales easily lost and sometimes absent in worn specimens; R5, M1, M2, and M3 separated, CuA1 and CuA2 present (
Fig. 9
); subbasal fascia directed from apex of costa toward posterior margin. Hindwing (length/width ratio 3.9) with R5 and M1 well separated, M3 and CuA1 separated (
Fig. 17
). Male abdominal tergum VIII subrectangular (
Fig. 24
).
Male genitalia (
Fig. 27
): uncus hoodlike, apically rounded, subequal in length with gnathos; ventral part of gnathos cushionlike, trilobed at apex, without basal articulation, dorsal part absent; valva with costal part sinuous, with bulbous base; posterolateral margins of vinculum well developed, symmetrical; tegumen narrower mesially than basally, basal width/length ratio 0.3; phallus as long as length of tegumen, straight, slen- der, with transverse, sclerotized band on ventral surface at base, without cornuti.
Female genitalia (
Fig. 45
): apophyses posteriores about
2 x
length of apophyses anteriores; apophyses anteriores about 1–
2
x length of abdominal segment VIII; antrum sclerotized, cylindrical, width subequal to length of ductus bursae; ductus bursae covered with spinules, with colliculum; signum a small plate supporting a digitate process.
Larva. Undescribed.
Pupa. Undescribed.
Diagnosis.
Arogalea
is superficially similar to the European genera
Stenolechia
,
Parastenolechia
,
and
Stenolechiodes
. However, the one known species,
A. cristifasciella
,
differs from other species in having the trilobed apex of the gnathos in male genitalia.
Arogalea
and
Pseudotelphusa basifasciella
differ from all other Nearctic Teleiodini in having forewings with white ground color, but the latter species differs in having the subbasal fascia extending from the wing base toward the posterior margin.
