Adixoa leucocyanea ( Zukowsky, 1929) 

( Figs 27, 28View FIGURES 21 – 28, 39View FIGURES 38 – 39, 41View FIGURES 40 – 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. AK 191 ( MNHB, Fig. 28View FIGURES 21 – 28). Additional Material. 1 ♂, Prov. Guangdong, Lianzhou, Dadongshan, 650 m, 16.V. 2012 ( Fig. 27View FIGURES 21 – 28, 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. 28View FIGURES 21 – 28) by Kallies (2007). We here report the discovery of the males of this species, which are described in detail below.

Redescription. Male ( Fig. 27View FIGURES 21 – 28). 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 R 4 and R 5 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. 39View FIGURES 38 – 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. AK 191, Fig. 41View FIGURES 40 – 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.
