Diagnosis. This species is distinguishable by the greyish-yellow area between the medial and postmedial lines of the forewing. L. acutiprocessa resembles L. anthyalus , but differs by the male genitalia. The uncus is long and pointed apically but that of L. anthyalus is snake head shaped apically; the basal process of the costa of this species is needle-like, but that of L. anthyalus is hook-like.

Description. Head. Dark-brown. Frons blackish-brown, convex; vertex with a cluster of erected black scales. Antenna of male and female filiform, brown. Labial palpus dark-brown, the second segment with thick and long scales apically, extending beyond frons. Thorax. Forewing length: male 13–14 mm, female 12–14 mm. Thorax dark-brown, patagia and tegulae covered with mixed greyish-brown scales, patagia longer than half of mesothorax. Legs brown, ends of segments greyish-white; hind tibia with two greyish-white hair-pencils at opposite side of spurs. Wing-pattern. Forewing dark-brown; subbasal line double, black, visible at costal margin; antemedial line double, black, wavy; medial line black, slightly wavy, arched between cell and anal margin, with two clusters of erected black scales anteriorly; reniform black; area between medial and postmedial lines greyish-yellow; postmedial line double, black, dentate with black patch at outer side near costal margin and thin, black, slightly wavy line between postmedial and submarginal lines; submarginal line black, slightly dentate, bordered with greyish-brown shadow anteriorly; terminal line black, interrupted at vein ends; fringes blackish-brown basally, greyish-brown terminally. Hindwing greyish-brown with basal half almost transparent, veins black. Underside: forewing greyishbrown with darker terminal half; postmedial line dark greyish-brown, band-like; terminal half of costal margin with four small greyish-yellow patches; hindwing with terminal half dark-brown, postmedial line same as on forewing. Abdomen. Dark-brown. Male genitalia. Uncus long, pointed apically. Gnathos short, connected, forming a small ring at middle. Valva long, narrow, basally triangular; sacculus with a series of long hairs; basal process of costa long, narrow, needle-like, longer than uncus. Saccus inverted triangular. Aedeagus long. Female genitalia. Ovipositor short, wide, with thick hairs. Apophyses posteriores long and thin, apophyses anteriores short. Ostium rounded. Post-ostial invagination small, triangular over ostium. Appendix bursae same size as corpus bursae. Corpus bursae rounded, with a small strip-like signum.

Material examined. Holotype: male, CHINA, Hainan: Jianfengling, 6.V.1973, coll. Chen Yixin ( IZCAS). Paratypes: Hainan: 6 females, Jianfengling, 7.VI.1973, 18.IV.1978, 13.IV.1980, coll. Zhang Baolin, Chen Yixin ( IZCAS). Guangxi: 1 female, Napo, Beidou, 550 m, 22.VI.2000, coll. Zhu Chaodong; 1 female, Pingxiang, 24.IV.1980 ( IZCAS). Guangxi: 6 females, Pingxiang, 11–17.V.1963, coll. Yang, Jikun ( CAU).

Distribution. China (Hainan, Guangxi).

Etymology. The specific name is derived from the Latin prefix acuti - (which means acute) and processus (which means process). This refers to the needle-like basal process in the costa of the male genitalia.

Remarks. The species Lophoptera pustulifera Walker, 1863 was recorded in China based on the specimens from Hainan cited above by Chen (1999). Here, we re-identified the specimens and stated that they represent a new species, therefore Lophoptera pustulifera is not distributed in China.
