description: Indomyrlaea Roesler & Küppers, 1979
Indomyrlaea Roesler & Küppers, 1979: 118; Roesler, 1983: 55. Type species: Indomyrlaea sutasoma Roesler & Küppers, 1979, by original designation and monotypy.
Diagnosis. This genus is sexually dimorphic: in the male, the flagellum basely has a shallow sinus, on which a row of black toothlet is covered by rough scale tufts, the labial palpus is elongate and obviously upturned beyond vertex, and the base of the forewing usually has dense and thick scales; in the female, the flagellum is common, the labial palpus is not elongate, and the base of the forewing is not thickened. The genus is also characterized by the male genitalia with the process of the gnathos trilobate, somewhat anchor-like, and the female genitalia with posterior half of corpus bursae weakly sclerotized, and ornamented with numerous long spines.
Generic characters. Adults (Figs 2−12). Frons rounded, with rough scales. Ocellus present. Chaetosema well developed. Antenna (Fig. 14) extends about half forewing; scape elongate; male flagellum with a gentle sinus, bearing a rough scale tuft and a row of black toothlet hiding in the tuft. Labial palpus upturned; in male (Fig. 15), second segment stout and vertically upturned beyond head, with a groove on inner surface; third segment very short and slightly bent forward; in female, second segment gently bend, without groove, third segment slightly longer than male, acuminate apically. Maxillary palpus in male (Fig. 16) pappi-shaped, same length and hiding in groove of second segment of labial palpus; in female cylindrical, fanned out distally. Tongue well developed. Forewing (Figs 17, 18) with dense and thick scales at base in male; with 11 vines, R2 stalked with R3+ 4 in basal half, R3+4 and R5 stalked for about 2/3 length of R5, M2 and M3 shortly stalked, CuA1 and M2+3 from lower angle of cell in male, from lower margin but close to lower angle of cell in female, CuA2 free; cell longer than half length of forewing. Hindwing with 10 vines: Sc close to or shortly stalked with Rs, M1 from upper angle of cell, shortly stalked with Sc+Rs, M2 and M3 long stalked, CuA1 and M2+3 stalked beyond cell for half length of CuA1, CuA2 from lower angle of cell; cell shorter than 1/4 of hindwing; anal area in male bearing long scales. Legs with tarsi having two lines of black spines.
Male genitalia (Figs 19, 21 − 25). Uncus triangular to trapezoidal. Apical process of gnathos trilobate, anchorshaped. Transtilla not or weakly sclerotized. Valva narrowly elongate, bearing dense long hair distally and near ventral margin; costa broad, strongly sclerotized, extending to end of valva, with or without distal process; sacculus narrow, strongly sclerotized, usually with a hooked process distally; clasper absent. Vinculum well developed, Ushaped, longer than width. Juxta U-shaped, weakly sclerotized on median area, with a pair of fingerlike lateral lobes. Aedeagus cylindrical, stout; cornuti present. Culcita present on 8th segment of abdomen, usually four pairs, three-dimensional arranged.
Female genitalia (Figs 20, 26−28). Anal papillae triangular. 8th sternite short and wide, collar-shaped. Apophyses anteriores and apophyses posteriores nearly same length. Antrum strongly sclerotized. Ductus bursae shorter than corpus bursae, partly sclerotized. Corpus bursae elongate, oval, posterior half usually weakly sclerotized, with a caudal bursa near junction of ductus bursae and corpus bursae. Signum comprised of numerous long spines. Ductus seminalis incepted at end of caudal bursa.
Distribution. China (Anhui, Fujian, Guangdong, Guangxi, Guizhou, Hainan, Henan, Hubei, Hunan, Jiangxi, Shaanxi, Sichuan, Xizang, Yunnan, Zhejiang), Bhutan, India, Indonesia (Sumatra), Japan, Korea, Sikkim, Sri Lanka.
