Description

Male (Fig. 1 c ). Wingspan 28-30 mm. Antennae filiform, dark brown; head ochrous, labial palpus long, upcurved, ochrous brown; thorax and tegulae covered in ochrous scales; abdomen dorsally dark brown. Fore-wing ground colour whitish ochrous with a broad dark brown striation from apex to middle of hind margin, reticulate pattern prominent. Hind-wing ground colour light brown, wing pattern not as obvious as fore-wing.

Male genitalia (Fig. 3 c ). Uncus slightly bifid apically, longer with two side processes. Subscaphium hairy. Gnathos strip-type with serried tooth. The valvae weak membranous elongated strips, median valval process hook-shaped, strongly sclerotised. Sacculus process sclerotised, apical part bifid, basal part moderately broader than apical part. Aedeagus short and broad with two clusters of cornuti.

Female: unknown.

Diagnosis

This wing pattern of the new species resembles S. rubricans Owada et Huang, 2016 , but the fore-wing is narrower and the outer margin is curved (triangular fore-wing in rubricans Fig. 1 c , d ), posterior line with a large dark brown area, the uncus is thinner and two processes are longer, the median valval process is thinner and more sclerotised, the sacculus process is slender (Fig. 3 c , d ).

Etymology

The specific name pararubricans is derived from the other specific name rubricans due to the resemblance of the present new species in morphological characters to the species S. rubricans .

Distribution

China: Guangdong (Shaoguan).
