description: <i>Promalactis anteromacularis</i> Wang, sp. nov. (Figs 4, 11) <b>Type material.</b> <b>China, Hainan:</b> Holotype ♂, Tianchi (18.73°N, 108.87°E), 787 m, 5.VIII.2016, leg. X Bai <i>et al.</i>, slide No. JYY17569. <b>Diagnosis.</b> The new species is superficially similar to <i>P. longimaculata</i> Wang, 2017, but it can be distinguished by the differently structured male genitalia. In <i>P. anteromacularis</i>, the costa has the distal half gradually widened to a truncate apex, the juxta has a slender basal lobe, and the aedeagus has many stout spines; in <i>P. longimaculata</i>, the costa is not widened distally, the juxta lacks a slender basal lobe, and the aedeagus does not have any spines. <b>Description.</b> Adult (Fig. 4). Forewing length 4.0 mm. Head with vertex black, frons brown. Labial palpus: second palpomere black mixed with greyish brown; third palpomere black except white at base and apex. Antenna: scape black on dorsal surface, grey on ventral surface; flagellum black, alternated with pale orange yellow on dorsal surface. Thorax black on anterior half, orange yellow on posterior half; tegula black. Forewing orange yellow; large elongate sub-triangular rust brown blotch from base widened to middle length of wing anteriorly, edged with a white line and sparse black scales along apex and ventral margin; apex with a black spot composed of some diffused black scales; tornus with a few black scales; fringe orange yellow. Hindwing and fringe grey. Foreleg black, tibia with a white dot at base and middle, tarsus white at apices of basal two tarsomeres and apical tarsomere; midleg grey ventrally, black dorsally, tibia with a white dot at middle, tarsus white at apices of basal two tarsomeres and apical tarsomere. Hindleg missing. Male genitalia (Fig. 11). Uncus wide at base, narrowed to distal 1/3, distal 1/3 uniform in width, apex rounded. Gnathos slightly shorter than uncus; mesial plate broadened medially, thereafter narrowed to rounded apex, distal 1/3 with scale-like protuberances. Tegumen divided from posterior 1/4; lateral arms slightly narrowed to rounded apex. Valva narrow basally, widened medially, narrowed from middle to rounded apex; costa very narrow, convex medially, with an overlapped, sparsely setose, sub-triangular area distally; sacculus with basal 2/5 uniformly narrow, concave at basal 2/5, then slightly widened to preapex, apex hooked, directed dorsad. Saccus inverted triangular, wide at base, narrowed to acute apex. Juxta rounded, bilobed posteriorly. Aedeagus straight, about 1.3 times length of valva, with many stout spines running from basal 2/5 to distal 1/5; cornutus very long, spine-like distally. Female unknown. <b>Distribution</b>. China (Hainan). <b>Etymology.</b> The specific epithet of the new species is derived from the Latin <i>antero-</i> and <i>macularis</i>, referring to the large blotch along the anterior area of the forewing.
