Diagnosis

The new species is diagnostic in the male genitalia by the subtriangular cucullus with a semiovate concavity on the ventral margin, a horn-shaped posterior lobe of the juxta, which is serrate laterally, and in the female genitalia by the tongue-shaped signum about half the length of the corpus bursae.

Etymology

The specific epithet is derived from the Latin “ serrat -” and “- lobus ”, referring to the laterally serrate posterior lobe of the juxta in the male genitalia.

Description

ADULT ( Figs 5A View Fig , 9A View Fig ). Wingspan 9.5–12.0 mm. Head dark yellowish brown. Antenna creamy white. Labial palpus yellowish brown; third palpomere slightly longer than second palpomere. Thorax and tegula dark yellowish brown. Forewing with costal margin almost straight except slightly arched basally, apex produced, termen oblique; ground colour yellowish brown; markings blackish brown: discal stigma small; discocellular stigma oblong; apex with blackish brown spot; fringe yellowish brown in basal half, blackish brown subterminally, pale brownish yellow terminally; R 3 close to R 4+5 at base, R 4 and R 5 stalked for about 3/5 length of R 5, R 5 to termen, M 2 and M 3 subparallel, CuA 1 and CuA 2 short-stalked. Hindwing grey; fringe pale yellow tinged with greyish brown; M 3 and CuA 1 stalked for about ⅓ length of M 3.

MALE GENITALIA ( Fig. 14A View Fig ). Uncus large U-shaped, longer than median process of gnathos, triangularly produced on anterior margin; caudal lobe horn-shaped, with dense setae. Gnathos with basal plate rectangular; median process broad in basal 2/5, narrowed to distal ⅓, then slender to pointed apex, curved ventrad preapically by right angle. Valva broad basally, narrowed to cucullus; cucullus shorter than half length of valva, subtriangular, narrowed from middle to bluntly rounded apex, straight on costal margin, densely setose, with semiovate concavity beyond middle on ventral margin; costal bar slender, angled at middle; sacculus taenioid, wide at base, narrowed to cucullus. Vinculum broad; saccus subtriangular with blunt anterior margin. Juxta shield-shaped, with denticle at middle below posterior margin, semicircularly produced at middle on anterior margin; posterior lobe large, horn-shaped, slightly shorter than juxta, serrated laterally. Aedeagus slightly longer than valva, wide at base, gently narrowed toward apex, nearly straight, without dorsal denticle, with numerous granules in vesica; cornuti consisting of two horns at basal ⅓ and before apex, respectively.

SEVENTH ABDOMINAL STERNITE ( Fig. 17H View Fig ). Anterolateral rib thin and curved, reaching to before posterior margin of sixth abdominal sternite; posterolateral lobe subtriangular.

FEMALE GENITALIA ( Fig. 20F View Fig ). Eighth abdominal sternite concave at middle on posterior margin.Apophyses posteriores about 3 times as long as apophyses anteriores. Lamella antevaginalis slightly sclerotized and semicirclular. Antrum sac-like, membranous. Ductus bursae slightly longer than corpus bursae, narrow in posterior ⅓, broad and with sparse conic spines in anterior ⅔, granulose anteriorly; ductus seminalis arising from middle of ductus bursae, slender. Corpus bursae elliptical, granulose; signum large, tongue-shaped, longer than half length of corpus bursae, densely denticulate, with longitudinal median furrow.
