CHRYSORTHENCHES CALLIBRYA SPECIES GROUP

Description: Head – Vestiture of vertex appressed but rough around temporal area. Antenna filiform in both sexes, two-thirds as long as forewing costa. Labial palpus slightly ascending, 4× longer than antennal scape; second labial palpomere with ventrodistally denser scale tuft; third palpomere longest. Maxillary palpi three-segmented, as long as antennal scape. Temporal and occipital areas with piliform scales.

Thorax – Forewing narrow, greenish; venation ( Fig. 1F) with Sc reaching margin slightly before middle of costa; R arising from near basal two-fifths of radius; Rs 1-3 reaching margin above apex; Rs 1 arising from anterior margin of accessory cell near basal two-fifths, slightly divergent from R; Rs 2 slightly convergent to Rs 1; Rs 2 and Rs 3 basally separate, divergent; Rs 3 and Rs 4 slightly divergent; Rs 4 reaching margin right below apex; M 2 parallel to M 1 and M 3; CuA 1 and CuA 2 sinuous, close to each other at middle; CuP vestigial as fold in basal five-sevenths; basal fork of 1A+2A near one-third of the length. Hindwing venation ( Fig. 1F) with Sc+R 1 reaching margin at middle of costa; Rs reaching margin above apex; M stem vestigial in basal five-sixths; M 1 slightly close to Rs at middle; M 1 and M 2 slightly divergent in distal half; M 2 nearly parallel to M 3; M 3 and CuA 1 divergent; CuA 1 parallel to CuA 2; CuP present; 1A+2A sinuous, close to CuP at distal one-third, with basal fork one-eighth of length; 3A straight.

Male genitalia ( Fig. 2A–F, H) – Uncus elongate, bifid apically; tuba analis broad, sparsely setose apically; subscaphium densely setose; tegumen subrectangular, setose laterally. Valva obovate or subrectangular, densely hairy, with large, sparselysetose; membranous disc basally, sparsely setose. Anellus densely spinulate. Saccus elongate, digitate, enlarged subapically. Phallus slightly sinuous, broadened basally, opening obliquely at apex, with needle-like and spiniform cornuti; carina strongly sclerotized, spiniform; vesica with a needle-like cornutus, a spinulate, digitate cornutus and five spiniform cornuti ( Fig. 2D–F).

Female genitalia ( Fig. 3A, B) – Ovipositor telescopic; papillae anales with setose, digitate protrusions dorsoapically. Abdominal segment IX with a pair of setose lobes ventrally. Ductus bursae slender, entirely sclerotized. Ductus seminalis arising on accessory sac of corpus bursae. Corpus bursae with accessory sac at middle; signum absent.
