The species was erroneously illustrated (without label data) by Lödl et al. (2012 : plate 15, figs 1, 2) as Cyana interrogationis ( Poujade, 1886 ) . Diagnosis . The forewing length is 18–20 mm in males ( 18 mm in the holotype ) and 18–21 mm in females. The new species is similar externally to C. phaedra but can be distinguished by its slightly wider forewing with a somewhat less elongate apex, the thinner red markings of the forewing with the less curved postmedial line, and the slightly paler hindwing. The male genital capsule of C. leechi differs from those of C. phaedra and C. moupinensis by the more elongate distal section of the valva. Additionally, the saccus of C. leechi is rectangular whereas it is U-shaped in C. moupinensis . The vesica structure of the new species is very similar to that of C. moupinensis and differs only by the presence of the lateral area of a spinulose scobination, which is absent in C. moupinensis . The female genitalia of C. leechi differ clearly from those of the related species by the much shorter sclerotized area in the basal section of the appendix bursae. Additionally, in the new species, the signum bursae is smaller and the gelatinous area of the posterior section of the corpus bursae is longer than in C. moupinensis . Distribution . The new species is known so far from Sichuan Province of China . Etymology . The species is named after John Henry Leech, author of C. phaedra and C. moupinensis .
