Adixoa leucocyanea (Zukowsky, 1929) (Figs 27, 28, 39, 41) Material examined. Holotype. ♀, “29. S. leucocyanea ” / “29.” [Lung tao shan, 19.VII.1917 (Prov. Guangdong, Mt. Longtou, ca 230 km N Guangzhou)], Gen. Prep. AK191 (MNHB, Fig. 28). Additional Material. 1♂, Prov. Guangdong, Lianzhou, Dadongshan, 650 m, 16.V.2012 (Fig. 27, Gen. Prep. 757, NSMT); 3♂, 2♀, Prov. Shaanxi, Lueyang, 20–29.VII.2011 (1♂, Gen. Prep. 760) (CAK). This species as redescribed in detail on the basis of the female holotype (Fig. 28) by Kallies (2007). We here report the discovery of the males of this species, which are described in detail below. Redescription. Male (Fig. 27). Wingspan 23 mm; forewing length 10.5 mm; body length 13 mm. Most body parts black. Head: frons grey, white laterally, labial palps white medially, neck plate white; pericephalic scales white laterally. Thorax: cranio-laterally white bordered; tegulae with medial borders white; with a white spot at the base of the forewing; mesothorax with some white distally; coxae, tibiae and tarsi partly white. Forewing: with well developed transparent areas, PTA extending all the way under the discal spot; ETA well-developed, base of the area between R4 and R5 transparent and part of the ETA, discal spot wide; discal area wide. Hindwing: transparent, outer margin relatively wide; discal spot well developed, long and rectangular. Abdomen: tergites 2, 4, 6 and partly 7 with narrow white distal borders; sternite 1 partly white; sternites 3–5 with white distal borders; anal tuft well-developed, with few white scales, valvae with white scales. Genitalia. Male (Gen. Prep. 757, Fig. 39). Valva long and narrow, dorsal setae field densely covered with well-sclerotized multifurcate hand-like setae; ventral field with simple setae; basal field well-separated, covered with short and very strong setae; gnathos very long, bilobed; uncus very long, straight and narrow; phallus narrow and simple. Female (Gen. Prep. AK191, Fig. 41). Apophyses very long and strong; ductus relatively short; corpus bursae small, simple; ostium very large, protruding, ventrally well-sclerotized. Variability. The specimens from Prov. Shaanxi have a somewhat narrower forewing discal spot and distal area, resulting in a slightly larger ETA. However, there were no detectable differences in the morphology of the male genitalia.
