Lepidoptera, Oecophoridae, Promalactis, new species, China
The genus Promalactis was established by
Promalactis is represented by the combination of the following characters: the smooth head with metallic lustre, the lanceolate forewings with various dark or white markings against yellow to deep ochreous brown ground colour; the variously shaped symmetrical or asymmetrical valvae and a narrow to very broad sacculus in the male genitalia; and a developed to ill-defined lamella postvaginalis and an elongate thin ductus bursae in the female genitalia.
Little is known about the biology of this genus.
Specimens examined in this study were collected in Anhui, Fujian, Guangdong, Guangxi, Guizhou, Hunan, Jiangxi, Sichuan, Zhejiang Provinces and Xizang Autonomous Region by light traps. Genitalia dissections and slide mounting methods followed

Labial palpus with basal and second segments dark orange on outer surface, basal segment light yellow on inner surface, second segment ochreous yellow on inner surface; third segment dark ochreous brown, white at apex, almost same length as second. Antenna with scape white except dark brown on anterior and posterior margins; flagellum white and dark brown on dorsal surface, dark brown on ventral surface. Thorax and tegula ochreous brown. Forewing orange; a narrow white fascia edged with dense black scales from beyond costal 2/3 to before lower angle of cell, then obliquely straight inwards to 3/4 of dorsum, its anterior1/4 widened and densely diffused with black scales; costal margin with an apical blackish brown spot; two white streaks arising from dorsal margin, edged with dense black scales: basal streak from dorsal 1/5 to above base of fold, straight, second streak from dorsal 2/5 to basal 1/3 of upper margin of cell, sinuate, area between two streaks ochreous brown; cilia orange yellow, dark brown along distal part of costal margin.

This species is similar to Promalactis tridentata Wang & Li, 2004, but can be separated by the sacculus distally curved like a scorpion tail and the cornutus about 1/2 the length of the aedeagus in the male genitalia; and the columniform lamella postvaginalis in the female genitalia. In Promalactis tridentata, the sacculus is nearly straight distally and the cornutus is about 1/3 the length of the aedeagus in the male genitalia; and the lamella postvaginalis is bell shaped in the female genitalia. This species is also similar to Promalactis papillata sp. n. The differences between them are stated under the latter species.

Adult with wingspan 11.0−14.0 mm. This species is similar to Promalactis parasuzukiella Wang, 2006, but can be separated by the sacculus with a digitate apical process, the slender rod-like saccus and the aedeagus with two spine-like apical processes in the male genitalia (Fig. 29); the M-shaped lamella postvaginalis and the oval signum in the female genitalia (Fig. 36). In Promalactis parasuzukiella, the sacculus has no digitate apical process, the saccus is semi-oval and the aedeagus has no apical process; and the lamella postvaginalis is absent and the signum is cross shaped.

This species is very similar to Promalactis jezonica (Matsumura, 1931), but can be separated by the forewing without the white dot at end of the fold (Fig. 14); the uncus having a triangular process at basal 3/5 ventrally, the broad leaf-like juxta, and the aedeagus with a short spine extending from dorsal side at distal 1/4 in the male genitalia (

This species is similar to Promalactis taibaiensis Wang, Zheng & Li, 1997, but can be separated by the aedeagus with two apical spines and two cornuti in the male genitalia; the ductus bursae concave ventrally at middle on posterior margin and membranous between posterior 3/5−3/4, and the signum with small distinct or indistinct teeth on posterior end in the female genitalia. In Promalactis taibaiensis, the aedeagus has four apical spines and one cornutus; the ductus bursae is slightly convex ventrally on posterior margin and entirely sclerotized, and the signum has dense teeth.
Adult (Fig. 15). Wingspan 9.5−11.5 mm. Head with vertex shining white, frons shining leaden grey, occiput yellowish brown. Labial palpus with basal and second segments yellow, third segment dark brown, almost same length as second. Antenna with scape white; flagellum white and black on dorsal surface, dark brown on ventral surface. Thorax and tegula ochreous brown. Forewing ground colour ochreous yellow; a narrow white fascia from costal 1/4 to dorsal 2/5, its inner margin edged with dense black scales, area ochreous brown from inner margin to base; a broad dark grey fascia at 3/5, tinged with black scales, its inner margin straight, outer margin sinuate; a wedge-shaped dark grey fascia from apex of costal margin along termen to end of fold, tinged with black scales; a narrow dark grey band along dorsal margin between two dark fasciae and connected them; cilia yellow, dark grey along distal part of costal margin, grey along distal part of dorsal margin. Hindwing and cilia dark grey.
Male genitalia (Fig. 30). Uncus nearly bell shaped, broad at base, gradually narrowed to 3/5, distal 2/5 slender, rounded at apex, laterally with setae. Gnathos tongue shaped, about 2/3 length of uncus, distal 1/2 scobinate, apex broadly rounded; lateral arm short, band shaped, about 1/3 length of gnathos. Tegumen branched from posterior 1/2, very narrow anteriorly. Valva narrowed and setose distally, apex narrowly rounded and directing dorsad; costa sinuate, concave at base and before apex, projected at middle. Sacculus narrow, slightly concave at basal 3/5 on dorsal margin, distal 2/5 setose; distal 1/5 free, serrate dorsally; apex pointed, directing dorsad, not reaching end of valva. Saccus slender, rod-like, slightly broader at base, rounded at apex, almost as long as valva. Juxta weakly sclerotized, short, with a small, slender awl-shaped basal process; lateral lobes broad, irregularly quadrate, rounded at apex, reaching middle of tegumen. Aedeagus gently curved, dilated distally, with two curved, basally joined distal spines; two joined or separate, spine-like cornuti present at middle: one very small, the other larger, sometimes deciduate.
Female genitalia (Fig. 38). Apophysis anterioris stronger than and about 1/2 length of apophysis posterioris. Ductus bursae about twice length of corpus bursae, posterior margin ventrally concave at middle and protruded laterally, posterior 3/5 sclerotized and sinuate, with some spinules at posterior 3/5, posterior 3/5−3/4 membranous and expanded, anterior 1/4 sclerotized, curved in semi-volute or sinuate; ductus seminalis arising from posterior 2/3 of ductus bursae. Corpus bursae rounded; signum small, nearly oval or rhombic, with small distinct or indistinct teeth on posterior end.

Adult with wingspan 12.5−14.0 mm. This species is similar to Promalactis bitaenia Park & Park, 1998, but can be separated by the forewing with a dark brown fascia (Fig. 16); the sacculus with a bundle of strong setae on the dorsal margin distally, the aedeagus about twice length of the valva and with a small subapical tooth in the male genitalia (
Female genitalia (Fig. 39). Apophysis anterioris about 1/2 length of apophysis posterioris. Eighth tergum with sparse long setae on posterior margin. Lamella postvaginalis heavily sclerotized, dorsal part elongate, nearly quadrangular, rounded on posterior margin, ventral part short, about 3/5 length of dorsal part, trapezoidal; lamella antevaginalis large, anterior 3/5 broad and slightly convex laterally, narrowed near anterior margin, anterior margin straight, triangularly protruded backward at anterior 3/5 laterally. Antrum elongate, tubular, posterior 1/3 broader. Ductus bursae weakly sclerotized except basal small portion heavily sclerotized, membranous near corpus bursae, with two plates near middle: one plate hand shaped, protruded, with three strong, curved spines on anterior edge; the other plate subtriangular, with very short spines on anterior edge. Corpus bursae small, rounded and membranous; signum absent.
