Diagnosis. Adult ( Fig. 15 ) wingspan 20.0–27.0 mm. Calamotropha latella is diagnosed by the white forewing with the pale yellow medial fascia bearing a large black medial band, and the pale yellow terminal margin with two black dots on posterior 1/4; in the male genitalia by the gnathos serrate mediodorsally, the elongate subovate valva with one small spiniform process near apex ( Fig. 38 ); in the female genitalia by the ductus bursae sclerotized on posterior 4/5, looped at anterior 2/5, and with a long sclerotized plate ( Fig. 59 ).

Remarks. Chen & Song (2002) described C. sawtoothella on the four male specimens, distinguished it from the closely allied species C. latella ( Snellen, 1890) mainly by the valva having one fold that is absent in the latter species. Bleszynski (1961) described C. latella based on 13 male and female specimens, in which he did not mention whether the valva had a fold or not. We collected both male and female specimens in this study. We found our male is identical to C. sawtoothella and the female is identical to C. latella in appearance and genitalia. Hence we propose C. sawtoothella as a new synonym of C. latella .

Distribution. China (Yunnan), India.
