Diagnosis. Loboschiza ellipsa sp. nov. is most similar to L. namphromensis sp. nov. They differ by the presence of a yellowish patch on the hindwing of L. ellipsa that is absent in L. namphromensis . The posteroventral region of the metathorax has two dense patches of oblong-ovate brown scales in L. ellipsa , whereas the same region has shortovate black scales in L. namphromensis . The hind tibia is shorter than first tarsal segment in L. ellipsa but is equal in length in L. namphromensis . The anterior margin of abdominal sternum IV has two elliptical patches of dense scales in L. ellipsa that are absent in L. namphromensis . Finally, the ventral pointed process of the cucullus has a bifid spine at its apex in L. ellipsa , compared to the pointed, curved spine in L. namphromensis .

Description. Head ( Fig. 8 View FIGURES 6–10 ): Lower frons orange white, upper frons and vertex yellowish orange mixed with light orange; labial palpi porrect, first segment light orange, second segment slightly widened to apex, light yellowish orange, slightly darkened to orange apically, third segment orange, paler at apex.

Thorax: Pronotal collar orange; tegulae orange red with elongate light brown patch in basal 2/3; mesonotum orange to orange red with light brown bands laterally; metathorax with two distinct patches of dense, shiny brown, oblong ovate scales posteroventrally ( Fig. 12 View FIGURES 12–13 ); hind tibia rather short, about 3/4 length of first tarsal segment, enlarged by two tufts of long whitish grey hair pencils on inner side, upper group reaching slightly beyond end of tibia, lower group longer, reaching end of first tarsal segment ( Fig. 15 View FIGURES 14–16 ). Forewing subrectangular, wingspan 12.0–12.5 mm in male ( Fig. 3 View FIGURES 1–5 ) (n = 10); costal margin evenly curved, termen rather straight and oblique; costal strigulae well developed, orange white separated by blackish streaks; wing pattern two-toned, basal 2/3 with light brown ground color, slightly darker to dorsum, with various shape of well-defined oblique orange bands, apical 1/3 with transverse, irregular sinuous orange striae on blackish ground, fringe scales blackish; underside light greyish brown with yellowish white spots along costa and termen between R 5 and M 1 and between M 1 and M 2. Hindwing broad, brown, slightly paler toward base, with irregular longitudinal yellowish patch medially; underside light greyish brown.

Abdomen: Sternum I+II with two tufts of moderately long fan-liked spiniform setae anteromedially, beyond with two small pits ( Fig. 18 View FIGURES 17–20 ), membrane between sternum III and IV with two curved, folded, weakly sclerotized lobes connected medially, outermost with coremata of dense long setae, beyond on sternum IV anteriorly with two sclerotized, elliptical, dense patches of very short spines, sternum VIII with an elongate subtriangular, moderately sclerotized plate medially. Male genitalia ( Fig. 23 View FIGURES 21–28 ) with tegumen ovate, moderately wide, with moderately dense scale sockets except lateromedially; uncus absent; socii moderately large, subtriangular, pendant, rounded apically, densely setose; gnathos composed of two narrow bands, sclerotized basally, arising at apical 1/3 of tegumen; vinculum wide; juxta subtriangular; caulis long, anellus surrounding basal 1/5 of phallus; phallus moderately long, slightly sinuate and tapered to pointed apex, with dense cornuti sockets; valva hook-shaped, dorsal margin slightly concave; ventrobasal 1/2 of sacculus with large, dense patch of setae, more dense medially, ventroapical margin with dense row of setae reaching toward neck; neck wide, concave ventrally, with sparse short setae; cucullus with dorsal portion dome-shaped, rounded apically, densely setose, ventral portion a long, narrow projecting lobe, tapered to apex, pointed ventrally with a strong bifurcate thorn at apex ( Fig. 24 View FIGURES 21–28 ).

Distribution. Thailand (Chanthaburi, Sa Kaeo, Trat province)

Etymology. The specific epithet ( ellipsa = ellipse) refers to the shape of two elliptical patches on sternum IV anteriorly.
