Review of the genus Calamotropha Zeller (Lepidoptera: Crambidae: Crambinae) from China, with descriptions of four new species Author Li, Weichun Author Li, Houhun text Journal of Natural History 2012 2012-11-30 46 43 - 44 2639 2664 http://dx.doi.org/10.1080/00222933.2012.724719 journal article 10.1080/00222933.2012.724719 1464-5262 5202189 Calamotropha formosella Bleszynski, 1961 ( Figures 3A , 4A and 5A ) Calamotropha formosella Bleszynski, 1961: 33 , figs. 18, 112. Diagnosis This species resembles C. okanoi Bleszynski, 1961 . It can be distinguished from the latter by the ductus bursae not conspicuously divided from the corpus bursae in the female genitalia, the apex of valva concave in C shape, and the vesica with a thornlike cornutus in the male genitalia. In C. okanoi , the ductus bursae is conspicuously divided from the corpus bursae, the valva is pointed distally, and the vesica bears a row of small spine-like cornuti. Figure 3.
