Only three species belonging to the genus Ectomyelois Heinrich, 1956 are recorded from China, of which two species, E. bipectinalis sp. n. and E. furvivena sp. n. are described as new. We discuss the status of Ectomyelois that has been treated as a junior synonym by previous authors; we treat it as a valid genus, revised status, based on characters of the venation and female genitalia. Photographs of the adults and illustrations of the genitalia are given, along with a key to the three known Chinese species.

Ectomyelois was established by
Ectomyelois was only represented by the common carob moth E. ceratoniae in China before this study. Herein the three species are described, including two new species: Ectomyelois bipectinalis sp. n. and E. furvivena sp. n.
Genitalia dissections were carried out following the methods described by Li (2002). The photographs of the adults and venation were taken with a Leica M205A, and photographs of the genitalia and details of head were taken with a Leica DM750, with Leica Application Suite 4.2 software to capture images. All the specimens examined are deposited in

Ectomyelois Heinrich, 1956: 43. Type species: Myelois decolor Zeller, 1881, by original designation.
Antenna of male usually shortly ciliate (bipectinate in E. bipectinalis sp. n.), basal shaft without notch or other modifications, of female simple. Labial palpus upturned, nearly reaching apex, third segment distinctly shorter than second. Forewing with R2 closely approximate to the stalk of R3+4+R5, M2 and M3 stalked for less than half of their length. Hindwing with Sc + R1 and Rs strongly anastomosed for most of their lengths, M2 and M3 stalked for not over half of their length. Male genitalia with uncus subtriangular to bell-shaped, apical projection of gnathos simple, slightly bent and furcated at apex, transtilla well developed, juxta U-shaped, with lateral lobes stout, vinculum U-shaped, more truncate and less tapering, phallus without cornutus. Female genitalia with signum consisting of an elongate patch of scobinations (absent in E. furvidorsella) and ductus seminalis from corpus bursae near junction of corpus bursae and ductus bursae.
Ectomyelois is similar to Apomyelois, but can be distinguished from the latter by the forewing with R2 closely approximate to the stalk of R3+4+R5, and the female genitalia with the ductus seminalis arising from the corpus bursae near junction of the corpus bursae and ductus bursae. In Apomyelois, the forewing with R2 shortly stalked with R3+4+R5, and the female genitalia with the ductus seminalis arising from anterior end of the corpus bursae.

This new species is notable superficially for its bipectinate male flagellum. It is much more similar to E. ceratoniae in genitalic structures, but can be distinguished from the latter by the narrower uncus with width almost equaling length, the widest part is at basal 2/5, the apical projection of gnathos approximately 3/5 length of uncus in male, and the elongate corpus bursae three times as long as wide in female. In E. ceratoniae, the uncus is more wide than long, the widest part at base, the apical projection of gnathos nearly the same length as uncus in male, and the corpus bursae is twice as long as wide in female.

The specific name is derived from the Latin prefix bi-, meaning two, and the Latin pectinalis, meaning pectinate, referring to the bipectinate male flagellum.

This new species is similar to E. bipectinalis sp. n., but can be recognized by the male antenna is not bipectinate, the uncus is rather abruptly narrowed beyond its broad base, tapered apical projection of the gnathos is about half length of the uncus and the inverse-goblet transtilla in the male genitaia. In E. bipectinalis sp. n., the antenna is bipectinate, the uncus protrudes triangularly at basal 2/5, the apical projection of gnathos is about 3/5 length of the uncus and the transtilla is trefoiled in the male genitalia. There is little difference in the female genitalia except the corpus bursae is much broader and the signum is smaller than in E. bipectinalis sp. n.

The specific name is derived from the Latin prefix furv-, meaning black, and the Latin vena, vein, referring to the forewing with black scales along its veins in this species.
The genus Ectomyelois is characterized by the wing venation, a signum with a patch of microspines and the inception of the ductus seminalis in the female genitalia. Two new species are assigned to this genus based on these characters. Ectomyelois bipectinalis sp. n. is unique for its bipectinate male flagellum, but the other characters, especially the genitalia, are in accord with the generic characters.
