Zhuang, Hailing, Owada, Mamoru & Wang, Min, 2014, First record of Hiroshia László, Ronkay & Ronkay from China, with description of a new species (Lepidoptera: Thyatiridae), Zootaxa 3794 (2), pp. 289-293 : 291-293

Hiroshia nanlingana sp. n.

( Fig. 3 )

Type material. Holotype male, China, Jiangxi, Wuyi Mountain, 1500 m, 19. May. 2011, leg. WANG Houshuang and WANG Min. Paratypes: 2 males, Nanling National Nature Reserve, Guangdong, China, 1200 m, 28. April. 2004, leg. WANG Min; 1 male, Nanling National Nature Reserve, Guangdong, China, 1200 m, 19. April. 2011, leg. XU Haiming, DENG Xiaohua, WANG Min; 2 females, Nanling National Nature Reserve, Guangdong, China, 1200 m, 25. April. 2010, leg. XU Haiming, DENG Xiaohua, WANG Min; 1 male, same data as the holotype.

Diagnosis. The new species is very close to Hiroshia albinigra by similar wing shape and forewing pattern, but the forewing is narrower, a part of pattern is white, black crosslines have large curve, reddish brown markings more bright. The male genitalia of this new species can be easily separated from the type species by the slender tegumen, the valval transtilla with a long sclerotized spine, the medial cleft of the ventral side of vinculum and the shorter and weaker carinal process of the aedeagus. The female genitalia differ from those of H. albinigra by the narrower ostial cutting with more rounded cleft around ostioporus, and the shorter but broader signum.

Description. Male and Female ( Fig. 3 A, 3B): Large species, wingspan 48–51 mm, length of forewing 23–25 mm. Head crouched. Eyes large and naked, surrounded by a round black cilium, frons hairy, palpi extended, third joint relatively slender. Antenna lamellate. Metathorax with symmetrical tufts of long hairs, with some greenish scales on the hairs. Forewing rather broad, usually darker brown, with apex pointed and white apical macula, outer margin with a row of black crenulate pattern. Postmedial area with greenish or white crosslines, and a distinctly black pattern; median area with clearly rosy-shaped pattern, orbicular stigma often absent or a small dot, reniform stigma usually with greenish scales, black crosslines distinct; antemedial area with broad white pattern, and porrect white scales present near the basal area. Hindwing brown with a distinct gray white inner zone. Female lack the huge anal tufts, and the external appearance is similar to the male.

Male genitalia ( Fig. 3 C): Long uncus and broad valva heavily sclerotized. Socii slender, shorter than uncus. Subconical tegumen with a fultura superior of reversed T-shaped. Valva of quadrangle, with long acute subcostal process and two variably long spines. Long, claw-like process present on transtilla, heavily sclerotized, as long as socii, with some extension appendices at base. Fultura inferior with symmetrical dentation of short spines. Saccus and vinculum well-developed. Aedeagus medium-long, rather straight and thick. Ventral process of carina hooked, cornuti field like a curled hedgehog.

Female genitalia ( Fig. 3 D): The papillae anales membranous, simple, hairy, with long apophyses posteriores retracting the 8th segment. Ostial part huge, broadly U-shaped, sclerotized, especially the outer margin of the Ushaped. Apophyses anteriores broader than apophyses posteriores, and dark and strongly sclerotized circular region present near the apophyses anteriores. Ostial section distinctly sclerotized. Ductus bursae short, corpus bursae membranous, signum fusiform, covered with some short spines.

Distribution. China (Jiangxi, Guangdong).

Etymology. The specific epithet is derived from one of the type localities.
