Diagnosis.

Ecpyrrhorrhoe longispinalis can be distinguished from E. digitaliformis and E. puralis in the male genitalia (Fig. 35 View Figures 34–37 ) by the valva gradually broadening to the sub-apex, a hook-shaped sella, a small, sclerotized, ball-shaped sclerite bearing two small spines on opposite sides on the anellus; in the female genitalia (Fig. 50 View Figures 50–52 ) by the antrum without sclerotized processes or triangular, wrinkled sclerites.

Description

(Fig. 19 View Figures 13–21 ). Head. Frons pale yellow, with white lateral bands. Vertex pale yellow. Labial palpus dark yellow, contrastingly white at base ventrally. Maxillary palpus dark yellow, pale terminally. Thorax. Dorsal side dark yellow or yellowish brown, ventral side white. Legs white to pale yellow. Wings. Forewing length: 9.0-13.0 mm. Forewing bright yellow, termen moderately arched; antemedial line fulvous, outwardly curved from 1/4 of costa to 1/3 of posterior margin; orbicular stigma dot-shaped, small, sometimes indistinct; reniform stigma comma-shaped, concave; postmedial line from anterior 3/4 distinctively curved to middle of CuA1, then bending to 1/3 of CuA2, and finally undulated to 2/3 of posterior margin; terminal line and fringe bright yellow. Hindwing yellow, costal area white, postmedial line fulvous, slightly dentate curved, outward from 2/3 of M1 to 1/2 of CuA1, arc-shaped, then bending inward along CuA1, reaching discocellular, then undulated to 2/3 of posterior margin; terminal line and fringe as in forewing. Abdomen. Pale yellow dorsally, black on distal part, white ventrally.

Male genitalia

(Fig. 35 View Figures 34–37 ). Uncus relatively thick, with basal half nearly triangular and naked. Valva curved and slowly broadening to rounded apex, with maximal width at sub-apex; sella hook-shaped with basal half densely setose; sacculus with distal 3/5 inflated into a triangular, rounded protrusion. Juxta with basal margin concave, distal half bifid into stout and pointed arms; anellus bearing a small and sclerotized ball, with two small spines on opposite sides (attached to distal end of phallus in Fig. 35 View Figures 34–37 ). Saccus rounded triangular. Phallus long and slightly curved, cornuti presented as a long sclerite and a long and strong spine on apical end.

Female genitalia

(Fig. 50 View Figures 50–52 ). Anterior apophysis ~ 2 × length of posterior apophysis. Lamella postvaginalis presented as a nearly trapezoidal sclerite. Antrum cup-shaped, strongly sclerotized, decorated with lots of small spines, those spines forming a circle, with a thumb-shaped, sclerotized process on the side of circle; colliculum narrow and moderately long; ductus seminalis connecting to anterior end of colliculum and with a short sclerite located opposite to colliculum; ductus bursae slender, length ~ 2 × as long as diameter of corpus bursae, basal 1/3 bearing a slim sclerite. Corpus bursae globular; rhomboid signum with maximal length almost 1/3 as long as diameter of corpus bursae; second (posterior) signum nearly V-shaped bearing sparse and long spines.

Distribution.

China (Hubei, Hunan).

Etymology.

The specific name is derived from the combination of Latin long - and spinalis (= with spine), referring to the vesica with a long and thick spine.
