Diagnosis. The wing pattern of Antaeola rhinosa sp. nov. is superficially similar to that of A. antaea (Meyrick, 1912) but differs by the absence of a longitudinal creamy band along the subcostal area that is present in A. antaea. The male genitalia of A. rhinosa are distinguished from those of A. antaea by having a long, strongly curved uncus, with a narrowed apex bearing a distinct, narrow, horn-like process dorsoapically, whereas the uncus of A. antaea has a wide, spoon-shaped apex without a horn-like process. The female genitalia of A. rhinosa are distinguished by a pair of extended large oval spinulose sterigma lobes, whereas A. antaea has an aciculate heart-shaped sterigma.
Description. Head (Figs. 3–4): Lower frons greyish white, upper frons light brown; vertex scales brown mixed with dark brown, with mostly light brown apices; antenna brown; labial palpus porrect, first segment light brown, white dorsally, second segment curved upward, widened apically, light brown mixed with brown with a yellowish white spot dorsobasally and a transverse brown band in apical 1/3 (paler in female), apical segment rather short and slender, obtuse, light brown mixed with brown.
Thorax: Pronotal collar light brown mixed with brown; mesonotum and tegulae dark brown mixed with brown, posterior crest dark brown with light brown apices; male hind tibia (Fig. 6) with a tuft of long, creamy scales (i.e., hair pencil) extending from base to terminal end. Forewing subrectangular, wingspan 12.8–16.0 mm in males (n = 20) (Fig. 1), 16.1–17.1 mm in females (n = 6) (Fig. 2); costal margin evenly curved, termen slightly sinuate with two white marks, first a narrow transverse stripe between wing apex and M 2, second a spot between M 3 and CuA 1; costal strigulae well developed, light brown to greyish white oblique streaks separated by small blackish streaks, strigulae 1–2 paired, 3–4 double paired, 5–7 paired, 8 and 9 single; male wing patten mostly darker than female; with brown ground color mixed with diffused longitudinal dark brown narrow stripes, especially between distinct dark brown wing veins, with a distinct longitudinal, light brown, narrow stripe below vein Cu, extending from wing base to end of closed cell, tornal area light brown with dark brown narrow stripes between veins M 3 to CuA 2, basal 1/2 of dorsum with a large, longitudinal, dark brown patch continuing as a row of dark brown spots to near tornus; fringe scales greyish white except dark brown from M 2 to between M 3 and CuA 1; underside brown except greyish white between 1A+2A and dorsum, with yellowish white spots along costa, termen with two transverse, narrow, whitish lines from wing apex to between M 1 and M 2 and from M 3 to CuA 1. Hindwing rather broad, subrectangular, brown, slightly paler toward wing base, anal margin sclerotized, folded (Fig. 5); underside brown.
Abdomen: Male genitalia (Figs. 7–9) with subrectangular tegumen, moderately sclerotized and wide, with moderately dense scale sockets laterally; uncus long and slender, basal 1/3 widened, subtriangular, with sclerotized lateral edges, remaining part narrow, medial 1/3 strongly hooked; apical 1/3 slightly tapered to obtuse apex, densely setose except at apex, with a small subtriangular lobe apicoventrally and a rather short, narrow, horn-shaped process, pointed apically, slightly curved upward; socius fused to sclerotized shoulder of tegumen, with moderately dense setae; gnathos large and sclerotized, originating at 1/2 of tegumen in length, pointing upward, lateral arms moderately wide with patch of small teeth laterally, apical 1/3 fused, subrectangular, with a narrow, median dentate patch, with wide, truncated apex and shallow excavation medially in some specimens (Fig. 8); vinculum moderately wide; juxta subtriangular; caulis rather short; anellus surrounding basal 1/5 of phallus; phallus moderately long, basal half subcylindrical, apical half tapered to apex, cornuti absent; valva long and slender, dorsobasally strongly curved; sacculus rather small, about 1/3 length of cucullus, with a patch of moderately dense setae basally, ventroapical corner round, irregularly serrate (Fig. 9), valva with strongly curved neck, medially with a short horizontal ridge, densely covered with short setae; cucullus long, slender, slightly narrowed medially, rounded apically, densely setose, mixed with dense spines along outer margin, ventrobasal angle round with an oblique patch of dense, moderately long spines reaching costal margin. Female genitalia (Figs. 10–12) with papillae anales densely setose, tergum VIII large and sclerotized, with subtriangular lateral extension densely microtrichiate, sternum VII moderately sclerotized, wide, deeply concave posteromedially, posterior half with dense microtrichia; ostium bursae small, elliptical; sterigma (Figs. 11–12) with a small semicircular ring-shaped lamella antevaginalis, with distinctly, large, sclerotized, spinulose lamella postvaginalis, a pair of separated ridges dorsally, ventrally fused with two large, protruding, divergent, oval spinulose lobes; colliculum narrow, 1/5 length of ductus bursae; ductus bursae long and slender; ductus seminalis arising near middle of ductus bursae; corpus bursae large, ovate, as long as ductus bursae, two small thorn-like signa from expanded subcircular sclerotized bases.
Distribution. Thailand (Chaiyaphum, Chanthaburi, Nakhon Nayok, Nakhon Si Thammarat, Narathiwat, and Sa Kaeo Provinces). This new species can be found in a wide range of elevation between 60– 1,140 m.
Etymology. The specific epithet rhinosa comes from rhinos (Greek) and refers to the horn-shaped process at the uncus tip that reminiscent of a rhinoceros’s horn.
