Diagnosis. This new species is externally similar to P. sectoralis Wang, Du et Li, 2013 . Promalactis pugnivalvata sp. nov. can be distinguished by having an apically bilobed valva, the symmetrical lateral lobes of the juxta not reaching base of uncus apically, and the cornutus has three apical spines. In P. sectoralis , the valva is bluntly rounded at the apex, the longer lobe of the asymmetrical lateral lobes of the juxta exceeds middle of uncus, and the spine-like cornutus. This new species is also similar to P. longivalvaris sp. nov., and the diagnostic characters that separate them are stated in the diagnosis of P. longivalvaris sp. nov.

Description. Adult ( Fig. 4 ) with forewing expanse 8.0 mm. Head with frons ochreous yellow, vertex shining white, occiput ochreous brown. Labial palpus with second palpomere pale ochreous yellow on inner surface, brown with white marking on outer surface; third palpomere blackish brown except white basally and apically, shorter than second palpomere. Antenna with scape white tinged with ochreous brown; flagellum brown on ventral surface, white alternated with black on dorsal surface. Thorax and tegula ochreous brown, thorax mixed with white scales posteriorly. Forewing ochreous brown, apex with a white spot tinged with yellow, with white markings edged with black scales: first fascia at base, second fascia from below costal 1/4 oblique to beyond dorsal 1/3, broader anteriorly, narrower posteriorly; costa with a large round white spot at 3/4, reaching lower angle of cell, surrounded with black scales except along costal margin; dorsum with a slender streak from beyond middle obliquely outward to below costal spot; cilia blackish brown along distal part of costa, ochreous yellow mixed with white around apex, grayish brown along distal part of dorsum. Hindwing and cilia brown. Fore and mid legs with femur grayish yellow, tibia blackish brown with white markings dorsally, with a tuft of long white scales at apex, tarsi blackish brown with white rings; hind leg grayish brown tinged with black scales.

Male genitalia ( Fig. 14 ). Uncus with basal 1/3 uniformly broad, narrowed from 1/3 to truncate apex. Gnathos membranous, rectangular, width 2 times its length. Tegumen branched from posterior 1/3, narrowed to apex laterally. Valva mitten-like, narrow at base, slightly widened to before apex; apex deeply concave at anterior 1/3, forming two lobes: dorsal lobe shorter and narrower than ventral lobe, with fine wrinkles apically; ventral lobe longer and wider than dorsal lobe, subtriangular, narrowed to rounded apex, setose; sacculus narrow, reaching ventral 2/5 of valva. Saccus triangular, pointed at apex, about half length of uncus. Juxta rectangular, bearing long setae along basal 1/3 laterally; lateral lobes narrowed to pointed apex, not reaching posterior margin of tegumen; basal rod reaching 2/5 of saccus anteriorly. Phallus slightly longer than valva, slightly curved medially; cortunus placed from basal 1/6 to before apex of phallus, slender, bulbous before apex, apically produced to three curved spines ( Fig. 14 a) of different length, longest spine curved sharply at middle.

Female genitalia ( Fig. 22 ). Apophysis anterioris about 2/3 length of apophysis posterioris. Lamella postvaginalis inverted broad triangular; lamella antevaginalis rounded. Antrum short, funnel shaped. Ductus bursae membranous, basal half relatively narrowed, distal half widened toward corpus bursae, with longitudinal carinae. Corpus bursae elliptic, signum absent.

Distribution. China (Hainan).

Etymology. The name is derived from the Latin pugnus (fist) and valvatus (valva), referring to the shape of the valva.
