Promalactis fortijuxtalis Wang, Du & Li , sp. nov.

( Figs 11 View FIGURES 9–16 , 45 View FIGURES 41–46 )

Type material: Holotype ♂, THAILAND, Khao Yai Nat. Park (12°49'N, 99°56'E), Nakhon Nayok Province, 700 m, 29.ix−6.x.1984, leg. Karsholt, Lomholdt & Nielsen, genitalia slide No. ZMUC-NK013 ( ZMUC) GoogleMaps . Paratype: 1 ♂, same data as holotype ( ZMUC) GoogleMaps .

Description. Imago ( Fig. 11 View FIGURES 9–16 ) with wingspan 11.5−12.0 mm. Head with vertex shining white, frons and occiput dark brown. Labial palpus with basal and second segments yellowish brown on inner surface, dark brown mixed with black on outer surface; third segment black, about same length as second. Antenna with scape white; flagellum with basal several flagellomeres white, remaining ones white and black on dorsal surface, dark brown on ventral surface. Thorax and tegula dark ochreous brown. Forewing dark ochreous yellow; markings white edged with black scales: costal margin with a narrow triangular patch at 3/5, obliquely extending down to midwing; three white streaks arising from dorsal margin: first one from dorsal 1/5 to base of fold, second one from dorsal 2/5 to basal 1/3 of upper margin of cell, broad and slightly arched, third one from dorsal 2/3 to lower margin of cell at distal 1/5; tornus with a small triangular spot; an ill-defined dark-gray streak along distal 1/5 of lower margin of cell; apex with a large wedge-like spot extending along termen, mixed with some black scales; cilia dark ochreous yellow, dark gray along distal part of costal and dorsal margins. Hindwing and cilia gray. Foreleg black, tibia with white spot near base and middle on dorsal surface, with a tuft of short white scales at apex, tarsus with white spots on dorsal surface; midleg with tibia and tarsus yellow on ventral surface, black on dorsal surface, tibia white in basal 1/3, and with a few white scales at middle on dorsal surface, with a tuft of long white scales at apex, tarsus with white spots on dorsal surface; hindleg yellow on ventral surface, black on dorsal surface, tarsus with white spots on dorsal surface.

Male genitalia ( Fig. 45 View FIGURES 41–46 ). Uncus small, nearly rounded, with a small U-shaped notch at middle on posterior margin. Gnathos about 3/5 length of uncus, subtriangular, curved backward; lateral arms narrow, about same length as gnathos. Tegumen branched from middle, rounded anteriorly. Valva very broad and short; costa very short, slightly concave; ventral margin with basal 3/4 convex, distal 1/4 concave; apex deeply concave, forming two apical processes: dorso-apical process short, triangular, basal 2/3 with a triangular fold setose apically; ventroapical process elongate, basally slender, distally broad elliptic and setose, serrate dorsally. Sacculus very broad, subtriangular, reaching basal 3/4 of ventral margin of valva. Saccus very broad, slightly longer than uncus, nearly semi-ovate, bluntly rounded anteriorly. Juxta very strong, sclerotized, narrow at base, with a heavily sclerotized, cymbiform basal process reaching apex of saccus, gradually broadened to 1/5, posterior 4/5 broadly U shaped, margined with dense strong spines dorsally, forming two knife-like lateral lobes, sinuate on posterior margin, setose, reaching base of uncus. Aedeagus curved, slightly shorter than juxta, distally sclerotized, narrowed triangularly, margined with blunt teeth; cornutus absent.

Female unknown.

Diagnosis. This new species is similar to P. spatulata Wang, 2006 . It can be separated by the dorso-apical process of the valva with a triangular fold in basal 2/3, ventro-apical process broad and elliptic distally and the very strong juxta broadly U shaped in the male genitalia. In P. spatulata , dorso-apical process of the valva has no fold, the ventro-apical process is large thorn-like and the juxta is slender in the male genitalia.

Distribution. Thailand (Nakhon Nayok).

Etymology. The specific name is derived from the Latin prefix fort- (= strong) and the Latin juxtalis (= juxta), referring to the very strong juxta in the male genitalia.
