Material examined. Hainan: 1♁, Duowenling (19.79°N, 109.76°E), Lingao County, 207 m, 20. VIII. VIII.2017, leg. X Bai et al., slide No. KYN21309; 1♁, Gaoshanling (19.93°N, 109.64°E), Lingao County, 171 m, 19.VIII.2017, leg. X Bai et al., slide No. KYN21311; 1♀, Datian Reserve (19.11°N, 108.79°E), Dongfang City, 56 m, 4.VI.2018, leg. X Bai et al., slide No. KYN21350.
Diagnosis. Calamotropha sperlingi is diagnosed by the pale yellowish white forewing with a large subtriangular black medial speckle, with a brownish yellow fascia from before black apical spot to above dorsum and parallel to the subterminal fascia, and the terminal fascia with four brown spots on posterior 3/7; in the male genitalia by the gnathos with spiniform processes at base laterally, and the sacculus with a spiniform process apically.
Redescription. Adult (Fig. 27). Wingspan 16.0–17.0 mm. Frons and vertex pale yellowish white. Maxillary palpus pale brown basally, pale yellow distally. Labial palpus pale yellow except first segment pale brown on outer surface. Antenna white dorsally, pale brown ventrally. Forewing pale yellowish white; medial fascia pale yellow, excurved to angle at anterior 1/4, then sinuate to dorsum; medial speckle black, large, subtriangular; subterminal fascia pale yellow, extending outward and excurved at anterior 1/3, thereafter slightly sinuate inward to dorsum; pale yellow fascia from before black apical spot to above dorsum and parallel to subterminal fascia; apical spot semicircular, black; terminal margin pale yellow, with four brown spots on posterior 2/5, indistinct; fringe pale yellow. Hindwing and fringe pale yellowish white. Legs pale yellow to brown. Abdomen pale yellow.
Male genitalia (Fig. 49). Uncus slender, aequilate except widened at proximal base, rounded at apex. Gnathos shorter and wider than uncus, slightly narrowed to rounded apex, with large spiniform process laterobasally. Valva equally wide from base to about middle, thereafter slightly narrowed to rounded apex, with a fold from middle width of base extending to middle length of valva, parallel to costa; costa convex medially; ventral margin obtuse, with a triangular medial process bearing a short spine, fold from before and beyond this medial process extending obliquely and parallelly inward to near base. Pseudosaccus thumb shaped. Saccus broad basally, narrowed towards obtuse apex. Juxta ovate. Phallus about 1.4 X length of valva, with dense spinules distally; ductus ejaculatorius arising from basal 1/6 of phallus; cornutus absent.
Female genitalia (Fig. 69). Papillae anales ovate. Eighth tergum longer than apophyses posteriores. Apophyses anteriores short. Antrum short. Lamella antevaginalis transversally banded, slightly narrowed medially. Ductus bursae straight, tubular posteriorly, widened toward corpus bursae anteriorly; ductus seminalis arising from ductus bursae medially. Corpus bursae elliptical, not obviously divided from ductus bursae; signum absent.
Distribution. China (Hainan).
Remarks. This study provides more detailed description of the adult and male genitalia. The female of this species is described for the first time.
