( Figs 5 , 22 , 36 )

Macrobathra myrocoma Meyrick, 1914: 218 . TL: India (Assam). TD: NHMUK.

Material examined. CHINA, Guangdong: 2♁ 2♀, 6.VIII.2002 – 14.VII.2007 ; Guangxi: 57♁ 41♀, 3.IV.2002 – 3.VIII.2020 ; Guizhou: 11♁ 9♀, 29.VII.2001 – 27.VII.2019 ; Hunan: 19♁ 14♀, 12.VIII.2001 – 7.VIII.2020 ; Fujian: 1♁ 7♀, 28.VII–2.VIII.2008 ; Zhejiang: 24♁ 11♀, 17.VIII.1999 – 12.VIII.2005 .

Diagnosis. Macrobathra myrocoma differs from its congeners in the male genitalia by the conical valva narrowed to narrowly rounded apex; and in the female genitalia by the ductus bursae anteriorly membranous and granulated, and the large globular corpus bursae with a pair of relatively smaller signa ( Fig. 36 ).

Description. Adult ( Fig. 5 ). Wingspan 10.5‒13.0 mm.

Male genitalia ( Fig. 22 ). Socius slightly asymmetrical; left brachium widened from base to basal 2/3, slightly narrowed from distal 1/3 to rounded apex, concave on outer margin; right brachium widened from base to distal 4/5, distal 1/5 concave on outer margin, rounded at apex. Valva conical, narrowed to narrowly rounded apex, with dense setae ventrally; right valva shorter than left valva. Saccus as long as left valva, almost aequilate, apex obtusely rounded. Anellus slightly narrowed to obtusely truncate apex on dorsal surface, widely band-shaped basally and sub-rectangular distally on ventral surface. Aedeagus cylindrical, with wrinkles.

Distribution. China (Fujian, Guangdong, Guangxi, Guizhou, Hunan, Zhejiang), India.

Note. Meyrick described this species based on a female. The male is described for the first time herein.
