Description

Adult (Fig. 1 a , b , c ). Wing expanse 11.0-12.0 mm. Head. Frons dark grey; vertex deep purple; occiput dark grey. Antenna deep purple with ocherous cilia. Labial palpus slightly upcurved; first segment ochre; second segment pale ochrous grey at the junction with first segment, overall greyish-purple; third segment dark greyish-purple with ochrous purple at the apex. Tongue ventrally greyish-ochre, dorsally pale grey. Thorax. Tegula orange. Thorax orange; prothorax dark grey; mesothorax with pale greyish-silver at caudal margin; metathorax dark grey, pale ochre at the caudal margin. Abdomen dark purple; second segment with ochrous white scales caudally; fifth segment dorsally white. Wing. Fore-wing entirely vermilion with grey base, bright vermilion at the edge of the apex; fringes fuscous, few bright vermilion at the apex. Hind-wing fuscous with dark ochrous base; in male, one frenulum originating from four pairs of strands; in female, three frenula originating from each strand; fringes fuscous. Male genitalia (Fig. 1 d , e ). Uncus blunt with numerous setae on the lateral margin; apically bifurcate and sharp. Gnathos absent. Valva broad, gently bent twice with round apex, slightly wider from the first bent part to the second bent part, narrower from the second bent part to the apex; costa round dorsally; cucullus bean-shaped with numerous setae, slightly shorter than twice the length of uncus; sacculus sclerotised, with ventrally long setae. Vinculum short and thick with blunt apex. Juxta round dorsally with very gently vertices. Anellar lobes developed, club-shaped. Aedeagus approximately twice longer than uncus; cornutus absent; from mid-point to apex narrower and sclerotised, other weakly sclerotised; weakly sclerotised rectangular plate near base; apical patch of stimuli sclerotised, with acute apex. Female genitalia (Fig. 1 f ). Papillae anales length ca. 1.3 times longer than wide, weakly sclerotised, with numerous short setae. Eighth abdominal segment weakly sclerotised, cephalodorsally round, with long setae irregularly arranged along the caudal margin. Apophyses posteriores slightly 1.5 times longer than apophyses anteriores. Ostium bursae cup-shaped, crescent-shaped sclerotised structure inner. Ductus bursae narrow, slightly longer than half of the corpus bursae. Corpus bursae with two crescent-shaped signa near the caudal margin. Ductus seminalis very narrow and long, originating at about half of ductus bursae with microspines overall; bulla small, at about 2 / 5 of ductus seminalis.

Diagnosis

This species is similar to A. ignipicta , but has differences in the marking of the fore-wing and structures of the genitalia. In A. ignipicta , the fore-wing is dark red with a black posterior margin and in the male genitalia, the costa is angled dorsally and the anellar lobes are oval-shaped. However, in this species, the fore-wing is entirely dark red and, in the male genitalia, the dorsal margin of the costa is rounded and the anellar lobes are club-shaped.
