Diagnosis.
In appearance Ecpyrrhorrhoe allochroa resembles E. damastesalis in the narrow forewing and yellowish hindwing without markings. However, it can be differentiated from E. damastesalis by its smaller size (forewing length: 8.0-10.0 mm), forewing scattered with yellowish brown scales and bearing brown markings (Fig. 3 View Figures 3–12 ), in the male genitalia (Fig. 22 View Figures 22–27 ) by the slender valva, the excurved sella with longer setae ventrally, the long and slender phallus, and long and curved, densely spinulose sclerite on anellus.
Description
(Fig. 3 View Figures 3–12 ). Head. Frons yellow, sometimes white medially, with white lateral bands. Vertex pale yellow. Labial palpus dark yellow or yellowish brown, contrastingly white at base ventrally. Maxillary palpus yellowish brown, pale terminally. Thorax. Dorsal side dark yellow or yellowish brown, ventral side white. Legs white to pale yellow. Wings. Forewing length: 8.0-10.0 mm. Forewing pale yellow, densely scattered with yellowish brown scales, lines and stigmata brown; antemedial line from ~ 1/4 of costa to 1/2 of posterior margin; orbicular stigma oblate, sometimes weak; reniform stigma comma-shaped, slightly concave or bending inwards at middle; postmedial line from 3/4 of costa, dentated beyond basal half of CuA1, bending inward to 1/3 of CuA2, then dentated to 2/3 of posterior margin; fringe dark brown. Hindwing yellowish white, with area pale yellow; fringe pale brown and whitish at tornus. Abdomen. Pale dark yellow or yellowish brown dorsally, white ventrally.
Male genitalia
(Fig. 22 View Figures 22–27 ). Uncus with basal 2/5 nearly triangular and naked. Valva slightly curved, of even width, apex obtusely rounded; sella thumb-shaped and excurved, setose, bearing several spines on ventral margin; sacculus with dorsal 3/5 inflated into a nearly triangular protrusion. Juxta shield-shaped, with base wide, distal 1/4 bifid into thick and short arms with membranous extension; anellus with a long and curved, densely spinulose sclerite (attached to distal end of phallus in Fig. 22 View Figures 22–27 ). Saccus rounded triangular. Phallus long and slender, distal part slightly curved upward and sclerotized, with a cluster of interlaced spicules on vesica; distal end with a bent, spine-like cornutus.

Etymology.
The specific name is derived from the Latin allochrous (= heterochromatic), referring to the color difference between the forewing and hindwing.
